Hybrid rice varieties are bred using male-sterile maternal lines, which are unable to self-pollinate. Here, the authors show that mutations of the tms5 gene, which codes for RNase ZS1, result in the accumulation of ubiquitin fusion ribosomal protein mRNAs at high temperature to confer genic male sterility.
