TL;DR: It is shown in rice (Oryza sativa) with Boro II cytoplasm that an abnormal mitochondrial open reading frame, orf79, is cotranscribed with a duplicated atp6 (B-atp6) gene and encodes a cytotoxic peptide and plays an additional role in promoting the editing of atp 6 mRNAs, independent of its cleavage function.

TL;DR: In this paper, a new mitochondrial gene, WA352, which originated recently in wild rice, confers the wild abortive male sterility (CMS-WA) because the protein it encodes interacts with the nuclear-encoded mitochondrial protein COX11.

TL;DR: It is reported that a new mitochondrial gene, WA352, which originated recently in wild rice, confers CMS-WA because the protein it encodes interacts with the nuclear-encoded mitochondrial protein COX11, and can be suppressed by two restorer-of-fertility genes, suggesting the existence of different mechanisms to counteract deleterious cytoplasmic factors.

TL;DR: The results show that rice disease defense genes are initially organized in an expression‐ready state by specific monoubiquitination of H2A and H2B variants deposited on their promoter regions, but are kept suppressed by the BRHIS1 complex, facilitating the prompt initiation of innate immune responses in response to infection through the stringent regulation of BRHis1.

TL;DR: This work introduces an efficient and flexible hpRNAi vector construction method via the isothermal in vitro recombination system (IR-hpRNAi), which rules out the requirement of engineering restriction enzyme cutting sites in target DNA fragments, and is ligation-independent.
