不亲和的 meaning in English
incompatible
Examples
- Most plants are hermaphrodite , but have mechanisms such as self - incompatibility that promote allogamy
许多植物是雌雄同体的，但它们存在自交不亲和的机制，从而促进异花受精。 - However , only did a few pollen germinate in inter - specific hybridization between cerasus fruticosa and c . avian and many pollen tubes are crosswise on stigma and couldn " t penetrated into style . although a few pollen tubes entered , they couldn " t continue to grow due to accumulation of callosity in pollen tubes . in view of above - mentioned results , the irregular growth of pollen was the main reason to cause the incompatibility of distant hybridization between cerasus fruticosa and c . avium
而草原樱桃与欧洲甜樱桃种间杂交授粉后花粉在柱头上虽少量萌发，但花粉管在柱头上横向生长，或盘绕，扭曲不能伸入花柱；个别进入花柱的花粉管先端因沉积胼胝质而中途停止伸长未能进入子房到达胚珠，从而说明这种杂交授粉后花粉管的不正常行为是导致草原樱桃与欧洲甜樱桃远缘杂交不亲和的主要原因。 - 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
在孢子体型自交不亲和的芸薹属中，已经鉴定出3个主要与s位点紧密连锁的基因，花粉中的配体scr和柱头中的受体slg与srk ：另外鉴定出4个不与s位点连锁的基因arc1 、 thl1 、 thl2和mod ，它们被认为是si反应的下游蛋白质因子，但是对它们的生物学功能了解的还比较少。 - " xiyuan4 " , a b . olereacea l . and " 2001817 " , a b . napus l . were bred by southwest agricultural university . here using them as materials , we studied and explored thoroughly the dna and cdna sequences of thl2 gene and mod gene with bioinformatical methods . for the first time , based on sequence data , we analyzed the structure , heredity and variation of the dna sequences encoding thl2 and mod , and foresaw the molecular mechanism in self - incompatibility signal process
本研究以西南农业大学繁育的高度自交不亲和的‘西园4号’甘蓝和‘ 2001817 ’油菜为试材，采用生物信息学的方法全面研究和探索性的分析了thl2基因和mod基因的dna与cdna序列，首次从序列数据出发研究这两个编码基因的结构与遗传变异，以及在自交不亲和性信号转导中的作用机理
