The Ga1 locus of the genus Zea is associated with novel genome structures derived from multiple, independent nonhomologous recombination events
{{output}}
The Ga1 locus controls cross-incompatibility between field corn and popcorn. The Ga1-S haplotype contains 2 types of pectin methylesterase (PME) genes, ZmPme3 and several copies of ZmGa1P that are expressed in silk and pollen, respectively. The ga1 haplotype c... ...
