A Plant-Specific Homolog Influences Gametophyte Development in Sexual Tetraploid Ovules.

Aposporous apomictic plants form clonal maternal seeds by inducing the emergence of non-reduced (2n) embryo sacs in the ovule nucellus and the development of embryos by parthenogenesis. In previous work, we reported a plant-specific () gene (-like) showing expression levels positively correlated with sexuality rates in facultative apomictic . -like displayed contrasting hybridization patterns in apomictic and sexual plant ovules from premeiosis to anthesis.
