A pair of non-Mendelian genes at the Ga2 locus confer unilateral cross-incompatibility in maize
Abstract
Unilaterial cross-incompatibility (UCI) systems are regulated by a male-female gene pair that are genetically linked, but no pair of the male and female determinants has been isolated so far. Here, the authors report the cloning of a pair of pectin methylesterases encoding genes at the Ga2 locus confer UCI in maize.
