Variation in the electrophoretic banding patterns of high molecular weight (HMW) glutenin subunits of 274 hexaploid wheat (Triticum aestivum) varieties from China was examined by sodium dodecyl sulfate polyacrylamide gel electrophoresis. Twenty-seven different major glutenin HMW subunits were identified. Each variety contained 3–5 subunits and 29 different glutenin subunit patterns were segregated. Seventeen alleles were identified based on comparison of subunit mobilities with those previously found for hexaploid wheat. Chinese hexaploid wheats exhibited particular allelic variation in glutenin HMW subunit composition and this variation differed from that found in wheats from Japanese and other countries. Average Glu-1 quality scores of 274 Chinese wheat varieties in the present study have been shown to be higher than that of Japanese wheats. Considerable genetic variation in the HMW glutenin subunit compositions of the Chinese wheats was observed in the present study and previously. Alleles from Chinese hexaploid wheat varieties have not been extensively introduced into Japan and other countries. The present data may indicate possible applications of Chinese germplasm in wheat breeding programs. To improve the wheat quality, genetic variation should be attempted through the introduction of genes of Chinese varieties into varieties in Japan and other countries.

Wheat Landraces

The endosperm storage proteins of 174 Japanese wheat (Triticum aestivum) landraces were fractionated by sodium dodecyl sulfate polyacrylamide gel electrophoresis to determine their high-molecular-weight (HMW) glutenin subunit composition. These are alleles for complex gene loci, Glu-A1, Glu-B1, and Glu-D1, that are present in Japanese hexaploid wheat landraces. These were identified by comparison with the subunit mobility previously found in hexaploid wheat. Twenty-four different, major glutenin HMW subunits were identified. Each landrace contained 3–5 subunits, and 17 different glutenin subunit patterns were observed for 13 alleles in Japanese landraces. Japanese landraces showed specific allelic variation in glutenin HMW subunits, different from those in non-Japanese hexaploid wheats.

Abstract Flower development is an important determinant of grain yield in crops. In wheat (Triticum spp.), natural variation for the size of spikelet and floral organs is particularly evident in Triticum turgidum ssp. polonicum (also termed Triticum polonicum), a tetraploid subspecies of wheat with long glumes, lemmas, and grains. Using map-based cloning, we identified VEGETATIVE TO REPRODUCTIVE TRANSITION 2 (VRT2), which encodes a MADS-box transcription factor belonging to the SHORT VEGETATIVE PHASE family, as the gene underlying the T. polonicum long-glume (P1) locus. The causal P1 mutation is a sequence rearrangement in intron-1 that results in ectopic expression of the T. polonicum VRT-A2 allele. Based on allelic variation studies, we propose that the intron-1 mutation in VRT-A2 is the unique T. polonicum subspecies-defining polymorphism, which was later introduced into hexaploid wheat via natural hybridizations. Near-isogenic lines differing for the P1 locus revealed a gradient effect of P1 across spikelets and within florets. Transgenic lines of hexaploid wheat carrying the T. polonicum VRT-A2 allele show that expression levels of VRT-A2 are highly correlated with spike, glume, grain, and floral organ length. These results highlight how changes in expression profiles, through variation in cis-regulation, can affect agronomic traits in a dosage-dependent manner in polyploid crops.
