【摘要】：為了從分子水平上探討優(yōu)質(zhì)小麥資源中LMW-GS等位基因與小麥品質(zhì)的關(guān)系,以及在改善小麥品質(zhì)方面的潛在價值,利用小麥Glu-A3和Glu-B3基因的特異引物從強(qiáng)筋型、中筋型和弱筋型小麥共計10份材料中分離出LMW-GS基因后進(jìn)行序列分析。結(jié)果表明,共發(fā)現(xiàn)14個新的核苷酸變異類型和4個肽鏈變異類型。其中,14個新的核苷酸變異類型中,4個為Glu-A3基因變異類型,1個為Glu-B3基因變異類型,9個為Glu-D3基因變異類型。值得注意的是,有2個半胱氨酸數(shù)目特殊的亞基類型被發(fā)現(xiàn),一個是來自師欒02-1含有9個半胱氨酸殘基的GluA3-18基因,另一個是來自偃展4110含有7個半胱氨酸殘基的GluD3-13基因。
[Abstract]:In order to explore the relationship between LMW-GS allele and wheat quality in wheat resources at molecular level and its potential value in improving wheat quality, the special primers of Glu-A3 and Glu-B3 genes were used to analyze the strong gluten type of wheat. LMW-GS gene was isolated from 10 middle gluten and weak gluten wheat and sequenced. The results showed that 14 new nucleotide variants and 4 peptide chain variants were found. Of the 14 new nucleotide variation types, 4 were Glu-A3 gene variants, 1 was Glu-B3 gene variants, and 9 were Glu-D3 gene variants. It is worth noting that there are two specific subunits of cysteine, one from the GluA3-18 gene containing 9 cysteine residues in Shi Luan 02-1, and the other from the GluD3-13 gene with seven cysteine residues in Yanchang 4110.
