Description
Giacomo Bongiorno and co-authors map in this 2026 study the gene pool of a forage grass that plays loose with chromosome counts and sex. Eragrostis curvula hosts many cytotypes, some multiplying genomes, some skipping sex via apomixis. The team gathered a diverse panel and built a pangenome by mapping reads to the reference, then assembling what did not fit.
Polyploid plants carried more new pangenome content than diploids. Genes tied to extra genomes clustered around cell-cycle and DNA copying roles, while apomixis-linked genes leaned to after-transcription control. Family trees and allele patterns split by ploidy as well. The work names candidate genes behind both tricks. Breeders gain leads for seedless forage lines.
