Toll9 from Bombyx mori functions as a pattern recognition receptor that shares features wi....
DOI: 10.1073/pnas.2103021118, Toll/Toll-like receptors (TLRs) are key regulators of the innate immune system in both invertebrates and vertebrates. However, while mammalian TLRs directly recognize pathogen-associated molecular patterns, the insect To....2021-05-07 11:28:58Ruonan Zhang, Xiaofeng Li, Jie

Low nitrogen conditions accelerate flowering by modulating the phosphorylation state of FL....
DOI: 10.1073/pnas.2022942118, Nitrogen (N) is an essential nutrient that affects multiple plant developmental processes, including flowering. As flowering requires resources to develop sink tissues for reproduction, nutrient availability is tightly l....2021-05-07 11:28:58Miho Sanagi, Shoki Aoyama, Aki

Character displacement drives trait divergence in a continental fauna [Evolution]
DOI: 10.1073/pnas.2021209118, Coexisting (sympatric) pairs of closely related species are often characterized by exaggerated trait differences. This widespread pattern is consistent with adaptation for reduced similarity due to costly interactions (i....2021-05-07 11:28:53Sean A. S. Anderson, Jason T.
