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. WebEvolution and Phylogeny of Self-Incompatibility Systems in Angiosperms A. M. Allen 2 & S. J. Hiscock 2 Chapter 2745 Accesses 50 Citations Abstract The evolution of self-incompatibility (SI) has been debated since its genetic bases were first fully described over half a century ago.
