AbstractWe show that the positioning of chloroplasts in plant cells affects the ability of photosynthetic organs to depolarize linearly polarized light through diffuse reflection. We apply this phenomenon for the detection of blue-light-induced chloroplast movements using light reflected from leaves…

AbstractBrown planthopper (Nilaparvata lugens, BPH) is a major pest that severely limits rice production. Although plant defense against BPH involves complex metabolic and structural responses, the role of non-protein amino acids (NPAAs) in this process remains poorly understood. Here, we demonstrate…

AbstractPlant Rho/ROP GTPases act as essential molecular switches in disease resistance. However, how their protein stability is regulated and integrated with lignin metabolism remains poorly understood. Here, we demonstrate that the cotton small GTPase GhARAC3 serves as a positive regulator of resistance…

AbstractPoplar adapts to different nitrogen environments by regulating root N uptake and assimilation processes, but the integrated regulatory mechanisms underlying these responses remain unclear. In this study, whole-genome resequencing was performed on 162 poplar germplasm resources (including natural…

AbstractArsenic is a toxic, carcinogenic metalloid that threatens human health through contaminated water and food. Arsenite [As(III)] efflux mediated by ACR3 transporters is an ancient detoxification mechanism conserved across prokaryotes, fungi, algae, and non-angiosperm land plants, yet plant ACR3…

AbstractNitrogen homeostasis in heterocyst-forming filamentous diazotrophic cyanobacteria depends on the coordination between two cell types: heterocysts, which fix atmospheric N2, and vegetative cells, which carry out oxygenic photosynthesis. Yet the cell-type-specific contribution of glutamine synthetase…
