Abstract: Manipulation of male fertility in a polyploid species requires attention to the interaction of male-fertility alleles of multiple genomes. In hexaploid wheat, single-genome heterozygotes for Ms26 provide differential levels of male fertility across genomes. Hexaploid wheat homozygous for mutations in the Ms26 gene on the A, B, and D genomes is male-sterile. Male fertility may be restored by sufficient levels of expression of Ms26 using native Ms26 or a transgene, which may be native to wheat or to another species, or a combination of native and transgenic alleles. CRISPR/Cas9 technology may be used to generate mutations in Ms26 in wheat or rice.

The spring pushes up on the flange to bias the locking pin in an upward, unlocked position and hold it there after the gate is opened.
