Fig. 1: Phylogenetic tree of Vigna based on CENH3 amino acid sequences.
From: Unequal contribution of two paralogous CENH3 variants in cowpea centromere function
Two variants of CENH3 (VuCENH3.1 and VuCENH3.2) were identified in all V. unguiculata accessions, diploid V. mungo, and tetraploid species of V. reflexo-pilosa. Other diploid Vigna species (V. angularis, V. umbellata, V. aconitifolia, V. radiata, V. trilobata, and V. vexillata) encode a single CENH3.
