A high-resolution electron cryo-microscopy structure of the mitochondrial respiratory supercomplex I + III2 from Arabidopsis thaliana shows that the component complexes stabilize each other. A complex I-ferredoxin, subunit B14.7 and the newly defined P9 subunit mediate supercomplex formation.
Plants often need to bend their organs during their growth and development. It is a complex process, and the different mechanisms involved are discussed in the light of recent findings about genes, signalling, modelling and biomechanics.
Cryogenic electron microscopy structure of respiratory supercomplex I + III2 from mung bean reveals interfaces, a new complex I subunit and differences in complex III2 versus other supercomplexes. Resting complex I adopts an intermediate conformational state and a non-canonical active/deactive response.
Potential climate benefits of farming seaweed are large but sensitive to uncertain yields and competition with phytoplankton. Carbon removal by sinking seaweed is much costlier than avoiding emissions by substituting seaweed for land-based crops.
Endogenous formation of nitroxyl has been discovered by real-time detection in plant cells. Evidence shows that nitroxyl has a specific accumulation pattern different from nitric oxide in response to senescence- and hypoxia-induced redox shifts.
This review explores recent advances in research on the regulatory and evolutionary mechanisms of plant specialized metabolism and extrapolates these findings to medicinal plants that synthesize rare molecules.
This Review summarizes our current knowledge from genomics and fossil records about the evolutionary transition from charophycean algae to embryophytes, with a focus on the progressive assembly of the embryophyte genetic innovations during terrestrialization.
eINTACT uncovers Xanthomonas bacterial exploitation of plant osmosignalling by its effector XopD to enhance virulence. This provides the basis for accurately elucidating functions of bacterial type-III effectors in natively infected plants.
A global synthesis reveals that removing woody plants cannot compensate for losses caused by their expansion. The effectiveness of removing woody plants depends on their identity and how long a site has been encroached.
The higher-order organization of the monoterpenoid indole alkaloid biosynthesis in Catharanthus roseus leaves was dissected using single-cell RNA sequencing. This work opens the door to elucidate the spatial distribution of plant specialized metabolism at single-cell resolution, which will improve our understanding of the biosynthesis, transport and storage of specialized metabolites.
PUB30/31 ensure the optimal signalling output of ERECTA for proper plant growth and stomatal development. A heterodimeric partner BAK1 is a kinase and a scaffold that activates PUB30/31, which in turn ubiquitinate ligand-activated ERECTA for degradation.
Species databases are critical tools for biologists and conservationists around the world, but a number of problems, including lack of common standards, are causing issues that even include the miscategorization of species as extinct when they are not.
Reviewing online resources and additional literature on national red lists, 361 extinct seed-plant taxa were identified. Of these, 556 herbarium specimens belonging to 161 extinct species were found to have a high ‘de-extinction candidate’ score.
Photorespiration is not a closed cycle. Around 23–41% of photorespiratory carbon is exported as serine under various photorespiratory conditions. The build-up and relaxation of glycine pools constrain a large portion of photosynthetic acclimation.
BIL1/BZR1 upregulates some brassinosteroid-responsive genes and downregulates others. An integrated approach linking genome-wide analyses with biochemical and structural analyses elucidates the molecular basis of gene repression by BIL1/BZR1.
The compartmentation of monoterpenoid indole alkaloid biosynthesis in periwinkle leaves was determined using single-cell RNA-seq, which reveals the spatial distribution of plant specialized metabolism at the single-cell resolution.
Chromatin accessibility dynamics profiling throughout the development of the stomatal lineage uncovers a crucial role for heterotypic cis- and trans-acting factors. These drive cell-fate commitment during specialized cell-type differentiation.
