2023年9月25日，万建民院士团队在The Plant Cell在线发表了题为“A CYP78As–SMG4–COPⅡpathway promotes grain size in rice”的研究论文。该团队在水稻中鉴定到一个调控水稻籽粒大小的关键因子SMG4，并阐明其分子机制，为水稻粒型改良提供了新的基因资源。
A new research project aims to unravel the physical limits of cell size in budding yeast, with the ultimate goal of learning more about how cells, the fundamental units of life, modulate size control ...
‘Frameshifting’ therapy for mast cell cancers reduces size, spread
mRNA c-KIT mast cells cancer cell
2021/8/11
A potential new treatment for mast cell cancers reduces the number of mast cells by 'mutating' the messenger RNA (mRNA) before it can deliver instructions for manufacturing the gene responsible for ce...

Mantis Shrimp Size Each Other Before Ceding A Fight
2018/2/1
To a mantis shrimp, walking away from a fight doesn’t mean being a wimp. It means recognizing who they’re up against and knowing when to bail rather than drag out a doomed battle, Duke University rese...

2017/4/27
Biologists have long known that bacteria grow faster and bigger when the quality of nutrients becomes better, a principle in microbial physiology known as the “growth law,” which describes the relatio...
Two single nucleotide polymorphisms in the caprine GnIH gene are associated with litter size
PCR-RFLP SNPs combined genotype candidate gene
2017/6/22
Gonadotropin-inhibitory hormone (GnIH) can decrease luteinizing hormone and/or follicle-stimulating hormone levels in rat, mouse, sheep, and cattle by the direct suppression of gonadotropin-releasing ...

There is increasing evidence for variation in
rates of nucleotide substitution among divergent taxonomic
groups. Here, we summarize published rate data and show a
strong relationship between substi...
