水稻株型與產(chǎn)量控制基因PAY1的克隆與功能分析
發(fā)布時間:2020-12-20 00:12
株型通常被定義為植物地上部分的三維立體結(jié)構(gòu),其主要構(gòu)成因素有株高、分枝(分蘗)模式、葉形和穗型等。株型是諸多農(nóng)藝性狀的綜合體,它直接影響和決定作物的產(chǎn)量。在作物的進(jìn)化和改良史中,合理的株型一直是高產(chǎn)育種的主要選擇方向。了解株型的遺傳機制將有助于培育出高產(chǎn)優(yōu)質(zhì)的作物新品種。本研究對野生稻滲入系YIL55進(jìn)行EMS誘變構(gòu)建突變體庫,從中選取一個株型變直立緊湊的突變體PAYl作為研究材料。YIL55表現(xiàn)為株高較矮、分蘗較多、分蘗角度大、穗粒數(shù)少及產(chǎn)量低。同YIL55相比,PAY1突變體表現(xiàn)為株高增加、分蘗減少、分蘗角度變小、莖桿變粗、穗子增大、穗粒數(shù)及產(chǎn)量增加等。本研究利用圖位克隆方法,分離了PAY1基因,并對其分子功能進(jìn)行解析。遺傳分析結(jié)果顯示,突變體表型性狀的改變是受一對顯性基因控制。利用PAY1突變體與日本晴雜交的F2群體,將PAY1定位在第8染色體長臂端一個約51 kb的區(qū)間內(nèi)。序列分析結(jié)果表明,定位區(qū)間的LOCOs08g31470基因編碼區(qū)第四個外顯子、第1244堿基處,有一個由G到A的突變,導(dǎo)致PAY1突變體所編碼的蛋白質(zhì)中一個氨基酸殘基由谷氨酰胺轉(zhuǎn)變?yōu)榫?..
