Abstract

Crosses homozygous for the duplication Dp(AR17) are barren regardless of RIP. Sad-1, a semi-dominant suppressor of meiotic silencing, suppresses the barrenness of duplication-heterozygous but not of duplicationhomozygous crosses. Could it be that in the context of the homozygous cross the sad-1+ allele is not detected as being unpaired, and consequently, Sad-1 fails to suppress meiotic silencing?

为什么粗神经孢子虫纯合子的大重复杂交不育

复制Dp(AR17)的纯合杂交无论RIP如何都是不育的。Sad-1是减数分裂沉默的半显性抑制因子，抑制重复杂合杂交的不育性，而不抑制重复纯合杂交的不育性。是否可能在纯合子杂交的情况下，sad-1+等位基因没有被检测到是未配对的，因此，sad-1不能抑制减数分裂沉默?本作品采用知识共享署名-相同方式共享4.0许可协议。这篇常规论文可在真菌遗传学报告:http://newprairiepress.org/fgr/vol51/iss1/6
