Whole genome duplication in Brassica rapa is accompanied by both expansion of the circadian transcriptome and widespread temporal reconfiguration of gene regulatory networks consistent with subfunctionalization among pairs of paralogs.
Tobacco plants containing xanthophyll astaxanthin show that both photosystems are fully functional in the absence of carotenes, and these pigments are not essential for photosynthesis.
Plants and humans use a shared mechanism, the eukaryotic metabolic sensor TARGET OF RAPAMYCIN protein kinase and its substrate, an RNA-binding protein called LARP1, to coordinate post-transcriptional gene expression.
Whereas theories of ecological diversity mostly consider continuously supplied nutrients, a seasonal model uncovers a general mechanism that controls diversity and reconciles conflicting experimental findings.
Convolutional neural networks and graph partitioning algorithms can be combined into an easy-to-use tool for segmentation of cells in dense plant tissue volumes imaged with light microscopy.
The first atomic resolution structure of a mitochondrial respiratory complex from plants provides insight into the assembly and evolution of respiration in autotrophic eukaryotes.
Transposable elements and gene amplifications can provide variation needed for novel trait refinement and adaptation to new niches, though a recalcitrant organism-environment mismatch may persist.
