From a phylogenetic analysis of the TREE domains of TaSG-D1 genes from 898 wheat accessions, the low-elongation allele found in T. sphaerococcum (and its associated phenotypic effects) likely arose via spontaneous mutation from T. aestivum after hexaploidization. Historically, wheat crosses were used to locate the s gene thought to be responsible for grain roundness (Sears, 1947; Salina et al., 2000); however, to date, the exact location and function of this gene has remained unknown. Different explants viz. Attempts to create commercial variety Triticum sphaerococcum Perc. (2013). cv. GSK-3s are known to inhibit downstream targets by facilitating the phosphorylation of serine and threonine residues. Second, the authors found that given the same thousand-grain weight, the flour extraction rate from semispherical grain from ND4332 plants was higher than it was from the more elongated grain of HS2 plants. Triticum sphaerococcum ingår i släktet veten, och familjen gräs. Enter multiple addresses on separate lines or separate them with commas. One year: continues to do very well. Due to multiple ploidy events that occurred during domestication and improvement, the subgenomes of hexaploid (AABBDD) wheat spp. The authors then tested whether the round grain phenotype was caused by a similar mechanism in T. sphaerococcum by obtaining premature termination mutants for the TaSG-D1 haplotype from the ND4332 line. Eats small amounts of wheat. Development 140: 1615-1620. In comparison to bread wheat it has higher protein content (Josekutty, 2008). 1617-1626 ISSN: 1438-2377 Grains of T. sphaerococcum are hemispherical, with a shallow crease. (B) Spikelets from OE-Tasg-D1 plants are shorter than those from OE-TaSG-D1 or wild-type plants. Wheat (Triticum spp), one of the oldest cultivated cereals, is a major food crop grown in many regions with temperate climates. The implications of this paper are twofold: first, the authors have identified Tasg-D1, a gene encoding a GSK-3 protein that negatively regulates cell elongation via BR signalling, as the s gene responsible for the round seed shape found in T. sphaerococcum. Genet. The genus Triticum includes the wild and domesticated species usually thought of as wheat.. INTRODUCTION The polyploidy is a … The authors then tested whether the round grain phenotype was caused by a similar mechanism in T. sphaerococcum by obtaining premature termination mutants for the TaSG-D1 haplotype from the ND4332 line. The authors noted that Tasg-D1 expression was pleiotropic, affecting plant morphological traits (including plant height and spikelet morphology) as well as grain shape and thousand-grain weight.

From a phylogenetic analysis of the TREE domains of TaSG-D1 genes from 898 wheat accessions, the low-elongation allele found in T. sphaerococcum (and its associated phenotypic effects) likely arose via spontaneous mutation from Triticum aestivum after hexaploidization. In these geologically new environments, a group of plants that have symbiotic association with humans evolved from wild plants through domestication in both the Old and New Worlds. Statistics. By whole-genome sequencing of populations from 25 subspecies within the genera Triticum … Växtportalen. A similar analysis of a TaSG-A1 homeolog with a mutation in the TREE domain showed that this gene may also be implicated in grain shape. Given its importance, extensive marker-assisted breeding of wheat varieties has been undertaken to improve the quality and reliability of cultivated wheat but requires the isolation of genetic elements responsible for phenotypes of interest. www.plantcell.org/cgi/doi/10.1105/tpc.20.00110. However, BRs are also known to regulate many other physiological processes, including those responsible for the pleiotropic phenotypes observed here (Zhu et al., 2013). Plant Cell. However, BRs are also known to regulate many other physiological processes, including those responsible for the pleiotropic phenotypes observed here (Zhu et al., 2013). Zhu, J., Sae-Seaw, J., and Wang, Z. Triticum sphaerococcum, also known as Indian dwarf wheat, is endemic to India and Pakistan and is distinguished from other cultivated wheat subspecies by the fact that it produces round grains.

OE-Tasg-D1 plants also showed delayed flowering, shorter plant and spikelet height, and lower thousand-grain weight than control plants. Divergent diploid genomes have been combined to produce new polyploid species by spontaneous hybridization between diploid (or diploid with tetraploid) Triticum or Aegilops species. Due to multiple ploidy events that occurred during domestication and improvement, the subgenomes of hexaploid (AABBDD) wheat spp. Plants homozygous for the premature termination mutation were taller, had longer spike length, and showed longer grains than wild-type plants. (A) Relative to the Fielder wild type, plants overexpressing Tasg-D1 (OE-Tasg-D1) show dwarfism, while plants overexpressing TaSG-D1 (OE-TaSG-D1) are marginally taller than wild-type plants. Tong, H., Liu, L., Jin, Y., Du, L., Yin, Y., Qian, Q., Zhu, L., and Chu, C. (2012). Analysis of the resulting plant and grain morphology revealed that lines containing OE-TaSG-D1 (cloned from HS2) showed longer grains than control plants, while lines containing OE-Tasg-D1 (cloned from ND4332) showed shorter, rounder grains (see figure). Triticum sphaerococcum (Perc. Historically, wheat crosses were used to locate the s gene thought to be responsible for grain roundness (Sears, 1947; Salina et al., 2000); however, to date, the exact location and function of this gene has remained unknown. Comparisons of near isogenic lines (NILs) revealed that NIL-Tasg-D1 plants were less sensitive to exogenous BR than NIL-TaSG-D1 plants and showed only marginal root lengthening when exposed to BR concentrations as high as 0.1 μM. Reactions of Hordeum chilense accessions H1 and H7 and their amphiploids, HT8, HT9 and HT28 (named as tritordeum) alongwith wheat lines, T22, T24 and T59 used in their synthesis, were studied for resistance to the Karnal bunt pathogen (Tilletia indica) of wheat. The 1984 Löve classification [] was part of a taxonomic revision of the Tribe Triticeae.Following a broad interpretation of the biological species concept, Löve defined genera by their unique genome constitution, either as genera of diploids or polyploids. Here, we isolated the grain-shape gene Tasg-D1 in T . In turn, Persian wheat is a tetraploid species originating on the southern slopes of the Greater Caucasus in Georgia (Mosulishvili et al., 2017). can be challenging to map. All rights reserved. The record derives from WCSP (data supplied on 2012-03-23) which reports it as an accepted name (record 449051) with original publication details: Wheat Pl. The implications of this paper are twofold: First, the authors have identified Tasg-D1, a gene encoding a GSK-3 protein that negatively regulates cell elongation via BR signaling, as the s gene responsible for the round seed shape found in T. sphaerococcum. Wheat (Triticum spp.) ), one of the oldest cultivated cereals, is a major food crop grown in many regions with temperate climates. sphaerococcum Tamworth, N.S.W. Taken together, these results indicate that Tasg-D1 negatively regulates cell elongation, thereby causing both the round grain phenotype and several other pleiotropic effects. GSK-3s are known to inhibit downstream targets by facilitating the phosphorylation of Ser and Thr residues. sphaerococcum (6x) Short wheat Central Asia Source: Zeven and Zhukovsky (1975) and Hawkes (1982) Classification of Indian Wheat Wheat is an annual plant of poaceae family.

Cheng et al. This result makes sense because Tasg-D1 was found to downregulate brassinosteroid (BR) signaling. Reclassification of Triticum according to Löve 1984, with nomenclatural corrections.. Six subspecies of hexaploid wheat ( Triticum aestivum ) have been identified, but the origin of Indian dwarf wheat ( Triticum sphaerococcum ), the only subspecies with round grains, is currently unknown. Importantly, this site was marked by previous studies as a probable location of the s gene responsible for the round-grain phenotype (Sears, 1947, Singh, 1987). Genetic variability for seedling root number within the genus Triticum was characterized to determine if this trait could be used in wheat breeding. The wheat varieties included six diploid, eight tetraploid, seven hexaploid and three octoploid species together with wheat relatives containing different genomes. This result makes sense because Tasg-D1 was found to downregulate brassinosteroid (BR) signaling. Importantly, this site was marked by previous studies as a probable location of the s gene responsible for the round-grain phenotype (Sears, 1947; Singh, 1987). ), also known as Indian dwarf wheat, is endemic to India and Pakistan, and is distinguished from other cultivated wheat subspecies by the fact that it produces round grains. Triticum turgidum University of Melbourne Plant 41-85 var. Polyploidy appears to have occurred spontaneously in the Triticeae tribe in different periods of history.

A previous study in rice showed that overexpression of a GSK protein with a mutated TREE domain disrupted seed elongation, causing plants to produce round grains (Tong et al., 2012). Triticum turgidum L. subsp. (Adapted from Cheng et al. © 2020 American Society of Plant Biologists. In addition, TREE domains are highly conserved across flowering plants, and their phosphorylation is an important step in BR signaling pathways (Choe et al., 2002). Triticum sphaerococcum (Perc. Sears, E. (1947). Since the beginnings of agriculture, agroecosystems (i.e. Due to multiple ploidy events that occurred during domestication and improvement, the subgenomes of hexaploid (AABBDD) wheat spp can be challenging to map. (2020) used positional cloning to identify and functionally characterize a gene linked to grain shape, designated Tasg-D1, near the centromere of chromosome 3 of the T. sphaerococcum D genome. Triticum sphaerococcum Percival; Triticum sphaerococcum Percival is an accepted name This name is the accepted name of a species in the genus Triticum (family Poaceae). Wheat (Triticum spp. Comparisons Between Wild-Type Wheat Plants and Those Overexpressing Tasg-D1 or TaSG-D1. Triticum sphaerococcum [1] är en gräsart som beskrevs av John Percival. (C) Grain from OE-Tasg-D1 plants is rounder and less elongated than grain from OE-TaSG-D1 or wild-type plants. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. Cheng et al.

Choe, S., Schmitz., R., Fujioka, S., Takatsuto, S., Lee, M., Yoshida, S., Feldmann, K., and  Tax, F. (2002). Comparisons of NILs revealed that NIL-Tasg-D1 plants were less sensitive to exogenous BR than NIL-TaSG-D1 plants, and showed only marginal root lengthening when exposed to BR concentrations as high as 0.1μM. Given this difference, the identification of Tasg-D1 as the gene responsible for the round-grain phenotype may permit the future breeding or genetic engineering of round-grained wheat cultivars that better optimize wheat productivity by enhancing flour extraction rate. The classification of Indian wheats is given below: As many as 18 species of wheat have been described and recognized by Percival (1921). In seeds, BR-deficient mutations have been linked to short cell length in seed tissue, resulting in rounder, less elongated grain (Jiang and Lin, 2013). Ripe for the Picking: Finding the Gene Behind Variation in Strawberry Fruit Color, by The American Society of Plant Biologists, Round Effects: Tasg-D1 Is Responsible for Grain Shape in Indian Dwarf Wheat. These early analyses used inheritance analyses to predict that the hypothetical s gene is incompletely dominant, and the authors confirmed this prediction by examining the segregation ratio of grain shape using the offspring of a residual heterozygous line generated by a common wheat HS2 (a large-grained wheat cultivar) and T. sphaerococcum. Wheat is a grass widely cultivated for its seed, a cereal grain which is a worldwide staple food. [2020], Figure 2.). In the 1950s growing awareness of the genetic similarity of the wild goatgrasses led botanists such as Bowden to amalgamate Aegilops and Triticum as one genus, Triticum.This approach is still followed by some (mainly geneticists), but has not been widely adopted by taxonomists. (2020). Department of Ecology, Environment, and Plant Sciences, Stockholm University, Svante Arrhenius väg 20, 10405 Stockholm, SE. The authors noted that Tasg-D1 expression was pleiotropic, affecting plant morphological traits (including plant height and spikelet morphology) as well as grain shape and thousand-grain weight. Given this difference, the identification of Tasg-D1 as the gene responsible for the round-grain phenotype may permit the future breeding or genetic engineering of round-grained wheat cultivars that better optimize wheat productivity by enhancing flour extraction rate. Triticum sphaerococcum , also known as Indian dwarf wheat, is endemic to India and Pakistan and is distinguished from other cultivated wheat subspecies by the fact that it produces round grains. The genus Triticum L. is composed of diploid, tetraploid, and hexaploid species, majority of which have not yet been discriminated clearly, and hence their phylogeny and classification remain unresolved. Due to multiple ploidy events that occurred during domestication and improvement, the subgenomes of hexaploid (AABBDD) wheat spp can be challenging to map. Index words: subtribe Triticinae, Aegilops, Triticum, ploidy level, isozymes. Triticum aestivum sphaerococcum is a ANNUAL. Has taken Triticum vulgare 30 twice on the return of symptoms and is thrilled with her progress over the last year. dicoccon (Schrank) Thell. sphaerococcum 1/T. 130: 1506-1515, Jiang, W. and Lin, W. (2013). We do not capture any email address. In seeds, BR-deficient mutations have been linked to short cell length in seed tissue, resulting in rounder, less elongated grain (Jiang and Lin, 2013). Functional characterization revealed that Tasg-D1 was a Ser/Thr protein kinase glycogen synthase kinase 3 (GSK-3) containing a distinctive TREE (Thr-283-Arg-284-Glu-285-Glu-286) domain. The gene C that controls compact spike in hexaploid wheat T. sphaerococcum is not allelic to gene C ... ploidy … has been an important staple food crop for mankind since the beginning of agriculture. The genus Triticum includes the wild and domesticated species usually thought of as wheat.. The vast majority of angiosperms are (or were once) polyploid, and as hexaploid bread wheat has undergone two ploidy events separated by approximately 0.5 million years, it represents an elegant model to study gene silencing over time in polyploids. aestivum 1/T.

Got Rosettes? The Plant List includes 562 scientific plant names of species rank for the genus Triticum.Of these 31 are accepted species names. Triticum monococcum subsp. In addition, TREE domains are highly conserved across flowering plants, and their phosphorylation is an important step in BR signalling pathways (Choe et al., 2002). IGOR V. SARKISSIAN Institute of Life Science, Texas A&M University, College Station, Texas 77843 Received February 2, 1970 OMMON wheat (Triticum aestivum) is adapted widely because of stabiliza'tion of favorable combinations of genes from its progenitors through polyploidy. Second, the authors found that given the same thousand-grain weight, the flour extraction rate from semispherical grain from ND4332 plants was higher than it was from the more elongated grain of HS2 plants. Arabidopsis brassinosteroid-insensitive dwarf12 mutants are semidominant and defective in a glycogen synthase kinase 3β-like kinase. Plant Physiol. Singh, D. (1987). Finally, electron micrographs of the grain pericarp revealed that cell elongation was lower in ND4332 plants than in HS2 plants. Wheat Information Service 64: 17-20.

It belongs to genus Triticum. Finally, electron micrographs of the grain pericarp revealed that cell elongation was lower in ND4332 plants than in HS2 plants. A similar analysis of a TaSG-A1 homeolog with a mutation in the TREE domain showed that this gene may also be implicated in grain shape. Theor. At present, wheat is grown over a wider area than any other commercial crop. increasing of the ploidy level led to a reduction of the intraspecies isozyme diversity, which might be related to the lower genetics variability in polyploids. At present, wheat is grown over a wider area than any other commercial crop. Average seedling root numbers were determined in the laboratory for 143 accessions of wheat including the diploid species Triticum boeoticum Boiss., T. monococcum L., and T. urartu Tum. The sphaerococcum gene in wheat. In the 1950s growing awareness of the genetic similarity (including some shared genomes) of the wild goatgrasses led some botanists to amalgamate Aegilops and Triticum as one genus, Triticum.This approach is still followed by some (mainly geneticists), but has not been widely adopted by taxonomists. 100: 686-689. The 1984 Löve classification [] was part of a taxonomic revision of the Tribe Triticeae.Following a broad interpretation of the biological species concept, Löve defined genera by their unique genome constitution, either as genera of diploids or polyploids. sphaerococcum gene used in this study. DWARF AND LOW TILLERING acts as a direct downstream target of a GSK-3/SHAGGY-like kinase to mediate brassinosteroid responses in rice.
