A natural allele of OsMS1 responds to temperature changes and confers thermosensitive genic male sterility

Abstract

Thermosensitive genic male-sterile (TGMS) lines are widely used for two-line hybrid rice breeding, but the mechanism of TGMS has not been fully elucidated. Here, the authors show that natural allele of the OsMS1 gene, encoding a histone binding PHD finger protein, responds to temperature change and confers TGMS in rice.
