Poaceae-specific MS1 encodes a phospholipid-binding protein for male fertility in bread wheat.

ABSTRACT: Male sterility is an essential trait in hybrid seed production for monoclinous crops, including rice and wheat. However, compared with the high percentage of hybrid rice planted in the world, little commercial hybrid wheat is planted globally as a result of the lack of a suitable system for male sterility. Therefore, understanding the molecular nature of male fertility in wheat is critical for commercially viable hybrid wheat. Here, we report the cloning and characterization of Male Sterility 1 (Ms1) in bread wheat by using a combination of advanced genomic approaches. MS1 is a newly evolved gene in the Poaceae that is specifically expressed in microsporocytes, and is essential for microgametogenesis. Orthologs of Ms1 are expressed in diploid and allotetraploid
