Measurement of self - incompatible by fluoroscope observation in non - heading chinese cabbage 白菜自交不親和性的熒光測定
Studies on breeding and seed reproduction technique of aijiaohuang self - incompatible line in non - heading chinese cabbage 大白菜自交不親和系小株采種高產(chǎn)技術
In sporophytically self - incompatible brassica , three s - linked genes , the pollen ligand scr , stigma receptor slg and srk , have been identified . in addition , four genes ( arc1 , thl1 , thl2 and mod ) that do not link to s locus have also been found , they are regarded as downstream protein factors of self - incompatibility ( si ) response , however , their biological function is not clear 在孢子體型自交不親和的蕓薹屬中,已經(jīng)鑒定出3個主要與s位點緊密連鎖的基因,花粉中的配體scr和柱頭中的受體slg與srk :另外鑒定出4個不與s位點連鎖的基因arc1 、 thl1 、 thl2和mod ,它們被認為是si反應的下游蛋白質(zhì)因子,但是對它們的生物學功能了解的還比較少。
