US Patent 11473103 Nucleus-encoded male sterility through mutation in cytochrome P450 oxidase

The invention relates to plants having a nucleus-encoded, recessive, male sterile phenotype and to the gene locus (gst) correlating therewith, including the gene which is responsible for the fertile/sterile phenotype and which is mutated in the sterile phenotype. The invention further provides methods for identifying the genotype correlating with the expression of features indicated above, and the corresponding genetic tools, such as hybridization probes and oligonucleotides. Also described is the use of the plants obtained according to the invention in hybrid breeding and in the production of products obtained from renewable raw materials, such as bioethanol, biogas and sugar-based products.
