Fine mapping and transcriptomics reveal OSG function in regulation of grain size and pollen fertility in rice (Oryza sativa)
Thursday, 22-01-2026 | 08:21
Grain shape is a critical factor that directly influences rice yield and quality, however, the molecular mechanisms underlying the regulation of grain shape development remains elusive. In this study, we characterized an oval-shaped grain mutant, osg, from the rice radiation mutagenesis mutant library via 60Co-γ ray irradiation. Compared to ZH11, the osg mutant exhibited decreased grain length and thousand-grain weight but increased grain width and thickness, while displaying significantly reduced plant height, tiller number,

Study: No One-size-Fits-All Representation of Trust in Science and Scientists
Study: No One-size-Fits-All Representation of Trust in Science and Scientists
Researchers from Australia and New Zealand studied the relationship of trust with social attitudes and motivations in forming perspectives on scientific issues such as climate change, vaccines, and gene drives. The findings are published in the Journal of Trust Research. Trust in science and scientists (TSS) is an emerging field of interest that explores science applications and their impact to society. The role of TSS among scientific topics may vary, depending on other psychosocial factors involved. Researchers surveyed 8,199 participants from New Zealand to explore TSS, focusing on vaccines, climate change, and gene drive.
