Incompatibility in angiosperms
WebJan 24, 2024 · Background: Self-incompatibility (SI) is a widely occurring outcrossing mechanism leading to an inability of a fertile seed plant to produce zygotes after self-fertilization. Loss and regain of SI have frequently occurred during angiosperm evolution under the fluctuating selective pressures of inbreeding and outcrossing. WebIn A. lyrata and other crucifers, this gene is a critical regulator of self-incompatibility which is expressed in the stigma. In A. thaliana, this gene is spliced differently, ...
