Ubiquitin-mediated degradation restricts spatiotemporal accumulation of the cytoplasmic male sterility protein WA352 to anthers in rice

Proceedings of the National Academy of Sciences, Volume 122, Issue 42, October 2025. <br/>SignificanceCytoplasmic male sterility (CMS) in plants helps breeders produce high-yield hybrid varieties. Genes that cause CMS are expressed throughout the plant, but the proteins they encode preferentially accumulate in anthers; how this occurs remains …
