Summary: Neo-tetraploid rice, developed by our research group, is a valuable germplasm with high fertility and strong heterosis. In this study, CRISPR/Cas9 technology was used to edit the TMS5 gene in neo-tetraploid rice, resulting in the development of two mutant lines, H2s and H3s, exhibiting characteristics of thermo-sensitive genic male sterility. These mutant lines were then crossed with tetraploid rice to produce F-1 hybrids, which showed significant advantages.

Summary: This study investigates the translational regulation during the reproductive stage in thermo-sensitive genic male sterile (TGMS) rice using translating ribosome affinity purification (TRAP) combined with RNA sequencing. The differentially expressed genes are enriched in processes related to pollen and anther development, including tapetum programmed cell death (PCD) and lipid metabolism. The results provide insights into the molecular basis of sterility in TGMS rice and have implications for genetic manipulation in breeding systems.

Summary: This study identified a new gene that affects the transition of cell wall during anther development, impacting the fertility restoration of male sterile plants. It was shown that a non-cell-autonomous pathway plays a key role in regulating the cell wall transition process, and slow development may be a critical mechanism for fertility restoration in P/TGMS lines.

Summary: This study analyzed the transcriptome of wheat PTGMS line BS366 during anther dehiscence under fertile and sterile conditions using RNA-sequencing. The differentially expressed genes (DEGs) were mainly related to hormone signal transduction pathway and starch and sucrose metabolism. qRT-PCR validation demonstrated the expression differences of critical DEGs in different conditions, suggesting their involvement in the regulation of anther dehiscence in BS366. A hypothesis model was proposed to reveal the regulation pathway of hormones and sucrose on anther dehiscence. These findings provide new insights into the molecular mechanisms of anther dehiscence in wheat and improve wheat hybrid breeding.

Summary: This study investigates the effect of clay nanosheet surface on the reactions of 1,2-bis(2'-methyl-5'-(N-methylpyrid-4-yl)-thien-3'-yl)perfluorocyclopentene dichloride (DAE2+). The results show that the quantum yield and rate of the reactions are influenced by the clay surface. The adsorption onto the surface enhances the thermo-ring opening rate while suppressing the photo-ring opening quantum yield.

Summary: The discovery and application of environment-sensitive genic male sterile (EGMS) rice germplasm have greatly contributed to hybrid rice production. In this study, a reverse TGMS (rTGMS) line, YnS, was found to be sterile under low temperature and fertile under high temperature. A genetic study identified the RTMS10 locus controlling the rTGMS trait in YnS. The findings provide insights for molecular breeding of rTGMS lines and understanding the rTGMS trait in rice.

Summary: In this study, the role of lncRNAs in the fertility transition of PTGMS rice lines was investigated through strand-specific RNA sequencing and computational analysis. The results showed that lncRNAs play a critical role in pollen mother cells meiosis, anther and pollen development during the fertility transition. Some lncRNAs were identified as precursors for miRNAs or endogenous target mimics, regulating the expression of miRNAs and mRNAs and contributing to the fertility transition process.

Summary: Bioinformatic analysis identified genes TaMut11 and TaSF3 associated with pollen development and male sterility induced by high-temperature in a new thermo-sensitive genic male sterility wheat line. Verification through gene silencing showed that silencing TaMut11 and TaSF3 caused pollen abortion, leading to a decline in fertility. These findings provided insights into the abortive mechanism in environment-sensitive genic male sterility wheat.

Summary: This study developed a high-yielding two-line restorer line R998 with high blast resistance, good grain quality, and high combining ability. By establishing a library of dominant genic male sterile lines, six restorer lines resistant to rice blast were developed. In addition, nine medium indica rice varieties were bred using R998 and its six derived restorer lines. This study provides an idea for group breeding using dominant genic male sterile polymerized favorable genes.

Summary: Water management plays a crucial role in determining rice yield, water use efficiency, uptake of arsenic and cadmium by plants, and greenhouse gas emissions in paddy fields. This study aimed to test the hypothesis that an alternate wetting and moderate drying regime could achieve multiple goals of increasing rice yield, saving water, and reducing harmful elements and greenhouse gas emissions. The results showed that this water management regime effectively increased rice yield, improved water use efficiency, reduced arsenic content, and decreased greenhouse gas emissions.

Summary: Root morphology and physiology have a significant impact on aboveground growth and yield formation in rice. This study aimed to investigate the root morphological and physiological differences among rice varieties with different nitrogen sensitivities and their relationship with grain yield. The findings indicated that the root biomass and activity were higher in N-insensitive varieties, and grain yield was positively correlated with root biomass in these varieties. In N-sensitive varieties, the oxidation activity and zeatin + zeatin riboside contents in roots were positively associated with grain yield, and the application of exogenous 6-BA increased root activity and improved grain yield. Therefore, selecting rice varieties with high root activity or enhancing root activity through cultivation measures could enhance grain yield, especially under lower nitrogen application rates.
