- Linkage mapping, molecular cloning and functional analysis of soybean gene Fg2 encoding flavonol 3-O-glucoside (1 → 6) rhamnosyltransferase.
- Rojas Rodas F, Rodriguez TO, Murai Y, Iwashina T, Sugawara S, Suzuki M, Nakabayashi R, Yonekura-Sakakibara K, Saito K, Kitajima J, Toda K, Takahashi R.Author information Graduate School of Life and Environmental Sciences, University of Tsukuba, Tsukuba, Ibaraki, 305-8518, Japan.AbstractThere are substantial genotypic differences in the levels of flavonol glycosides (FGs) in soybean leaves. The first objective of this study was to identify and locate genes responsible for FG biosynthesis in the soybean genome. The second objective was to clone and verify the function of these candidate genes. Recombinant inbred lines (RILs) were developed by crossing the Kitakomachi and Koganejiro cultivars. The FGs were separated by high performance liquid chromatography (HPLC) and identified. The FGs of Koganejiro had rhamnose at the 6″-position of the glucose or galactose bound to the 3-position of kaempferol, whereas FGs of Kitakomachi were devoid of rhamnose. Among the 94 RILs, 53 RILs had HPLC peaks classified as Koganejiro type, and 41 RILs had peaks classified as Kitakomachi type. The segregation fitted a 1:1 ratio, suggesting that a single gene controls FG composition. SSR analysis, linkage mapping and genome database survey revealed a candidate gene in the molecular linkage group O (chromosome 10). The coding region of the gene from Koganejiro, designated as GmF3G6″Rt-a, is 1,392 bp long and encodes 464 amino acids, whereas the gene of Kitakomachi, GmF3G6″Rt-b, has a two-base deletion resulting in a truncated polypeptide consisting of 314 amino acids. The recombinant GmF3G6″Rt-a protein converted kaempferol 3-O-glucoside to kaempferol 3-O-rutinoside and utilized 3-O-glucosylated/galactosylated flavonols and UDP-rhamnose as substrates. GmF3G6″Rt-b protein had no activity. These results indicate that GmF3G6″Rt encodes a flavonol 3-O-glucoside (1 → 6) rhamnosyltransferase and it probably corresponds to the Fg2 gene. GmF3G6″Rt was designated as UGT79A6 by the UGT Nomenclature Committee.

- Genome-wide association mapping of yield and yield components of spring wheat under contrasting moisture regimes.
- Edae EA, Byrne PF, Haley SD, Lopes MS, Reynolds MP.Author information Department of Soil and Crop Sciences, Colorado State University, Fort Collins, CO, 80523, USA, erenakae@yahoo.com.AbstractKEY MESSAGE: A stable QTL that may be used in marker-assisted selection in wheat breeding programs was detected for yield, yield components and drought tolerance-related traits in spring wheat association mapping panel. Genome-wide association mapping has become a widespread method of quantitative trait locus (QTL) identification for many crop plants including wheat (Triticum aestivum L.). Its benefit over traditional bi-parental mapping approaches depends on the extent of linkage disequilibrium in the mapping population. The objectives of this study were to determine linkage disequilibrium decay rate and population structure in a spring wheat association mapping panel (n = 285-294) and to identify markers associated with yield and yield components, morphological, phenological, and drought tolerance-related traits. The study was conducted under fully irrigated and rain-fed conditions at Greeley, CO, USA and Melkassa, Ethiopia in 2010 and 2011 (five total environments). Genotypic data were generated using diversity array technology markers. Linkage disequilibrium decay rate extended over a longer genetic distance for the D genome (6.8 cM) than for the A and B genomes (1.7 and 2.0 cM, respectively). Seven subpopulations were identified with population structure analysis. A stable QTL was detected for grain yield on chromosome 2DS both under irrigated and rain-fed conditions. A multi-trait region significant for yield and yield components was found on chromosome 5B. Grain yield QTL on chromosome 1BS co-localized with harvest index QTL. Vegetation indices shared QTL with harvest index on chromosome 1AL and 5A. After validation in relevant genetic backgrounds and environments, QTL detected in this study for yield, yield components and drought tolerance-related traits may be used in marker-assisted selection in wheat breeding programs.

- Introduction of chromosome segment carrying the seed storage protein genes from chromosome 1V of Dasypyrum villosum showed positive effect on bread-making quality of common wheat.
- Ruiqi Z, Mingyi Z, Xiue W, Peidu C.Author information National Key Laboratory of Crop Genetics and Germplasm Enhancement, Cytogenetics Institute, Nanjing Agricultural University, Nanjing, 210095, Jiangsu, China.AbstractKEY MESSAGE: Development of wheat- D. villosum 1V#4 translocation lines; physically mapping the Glu - V1 and Gli - V1 / Glu - V3 loci; and assess the effects of the introduced Glu - V1 and Gli - V1 / Glu - V3 on wheat bread-making quality. Glu-V1 and Gli-V1/Glu-V3 loci, located in the chromosome 1V of Dasypyrum villosum, were proved to have positive effects on grain quality. However, there are very few reports about the transfer of the D. villosum-derived seed storage protein genes into wheat background by chromosome manipulation. In the present study, a total of six CS-1V#4 introgression lines with different alien-fragment sizes were developed through ionizing radiation of the mature female gametes of CS--D. villosum 1V#4 disomic addition line and confirmed by cytogenetic analysis. Genomic in situ hybridization (GISH), chromosome C-banding, twelve 1V#4-specific EST-STS markers and seed storage protein analysis enabled the cytological physical mapping of Glu-V1 and Gli-V1/Glu-V3 loci to the region of FL 0.50-1.00 of 1V#4S of D. villosum. The Glu-V1 allele of D. villosum was Glu-V1a and its coded protein was V71 subunit. Quality analysis indicated that Glu-V1a together with Gli-V1/Glu-V3 loci showed a positive effect on protein content, Zeleny sedimentation value and the rheological characteristics of wheat flour dough. In addition, the positive effect could be maintained when specific Glu-V1 and Gli-V1/Glu-V3 loci were transferred to the wheat genetic background as in the case of T1V#4S-6BS·6BL, T1V#4S·1BL and T1V#4S·1DS translocation lines. These results showed that the chromosome segment carrying the Glu-V1 and Gli-V1/Glu-V3 loci in 1V#4S of D. villosum had positive effect on bread-making quality, and the T1V#4S-6BS·6BL and T1V#4S·1BL translocation lines could be useful germplasms for bread wheat improvement. The developed 1V#4S-specific molecular markers could be used to rapidly identify and trace the alien chromatin of 1V#4S in wheat background.
