GmMs1 encodes a kinesin-like protein essential for male fertility in soybean

The application of heterosis is a promising approach for greatly increasing yield in soybean (Glycine max L.). Nuclear male sterility is essential for hybrid seed production and the utilization of heterosis. Here we report the cloning of the gene underlying the soybean male-sterile mutant ms-1, which has been widely used for recurrent selection in soybean breeding programs
