Why China should reassess how it rewards young scientists
Talent schemes helped to propel China to the forefront of global science. But the system places undue emphasis on prestigious titles as a means to secure career prospects, putting pressure on young researchers.

Very happy to see that SUBER GENE1 (SBG1; At1g52565) is now annotated in TAIR and Aramemnon! We identified this gene through a GWAS on natural variation in endodermal suberin and had the privilege of naming it. For those interested, the study can be found here: www.nature.com/articles/s41...

Unlike its wild ancestor teosinte, maize lost much of its seed protein during domestication. A paper @nature discovers teosinte genes that, when expressed in modern maize, increase seed protein without lowering crop yield. shorturl.at/zdsvY & highlight @natplants.nature.com: shorturl.at/e3f6C

Teosinte alleles enhance nitrogen assimilation and seed protein without lowering crop yield when expressed in modern maize, providing a powerful strategy for crop improvement to meet future population demands.

Water is essential to life; so how do cells sense and respond to the stress associated with changes in water levels? Work @nature shows that when water is scarce, the plant protein SAM8 forms condensates, trapping RNA-processing factors and so reprogramming translation. shorturl.at/4VZQf
nature.com
Cellular water-potential sensing through biomolecular condensation - Nature
Plants sense water deficiency through SAM8 protein condensation, which responds to reduced hydration and triggers stress adaptation by altering RNA export and gene translation.

Ancient hybridization underlies tuberization and radiation of the potato lineage
Genomic and functional analyses reveal that the potato lineage originated from a homoploid interspecific hybridization event between the Tomato and Etuberosum lineages 8–9 million years ago. The alternate inheritance of highly divergent parental alleles drove the origin of tubers and explosive species diversification and niche expansion into the high Andes.
