Molecular cytogenetics (FISH, GISH) of Coccinia grandis : a ca. 3 myr-old species of cucurbitaceae with the largest Y/autosome divergence in flowering plants.

Cytogenetic and genome research - 1 Jan 2013

Sousa A, Fuchs J, Renner S S

Abstract excerpt

The independent evolution of heteromorphic sex chromosomes in 19 species from 4 families of flowering plants permits studying X/Y divergence after the initial recombination suppression. Here, we document autosome/Y divergence in the tropical Cucurbitaceae Coccinia grandis, which is ca. 3 myr old. Karyotyping and C-value measurements show that the C. grandis Y chromosome has twice the size of any of the other...
