Evolution of the self-incompatibility system in the Brassicaceae: identification of S-locus receptor kinase (SRK) in self-incompatible Capsella grandiflora.

abstract：:Determination of mammalian sex depends on the presence or absence of a functional testis. Testes are determined by the activity of the testis determining factor encoded by the sex determining gene, Y (SRY) located on the Y chromosome. Considerable evidence suggests that the SRY gene is the only gene on the Y chromosom...
