Root expansion microscopy (ROOT-ExM) achieves super-resolution expansion microscopy in plants.

The development of expansion microscopy in the Arabidopsis root enabled the imaging of molecular targets in tissues at diffraction-unlimited resolution.

Long-term heat stress does not affect photosynthesis in the C₄ grass Setaria viridis owing to an effective acclimation response of carbon assimilation, although it inhibits plant growth.

An all-in-one CRISPR toolbox is developed to aid guide RNA library-based loss-of-function and gain-of-function screens in plants.

The kinesin-like protein POS3 dynamically associates with kinetochores and facilitates chromosome alignment in coordination with the microtubule polymerase MOR1 during mitosis.

The Arabidopsis blue-light receptor CRY1 and its downstream HY5 protein optimize daytime stomatal conductance through spatiotemporal control of flavonols and ROS homeostasis in guard cells.

A noncanonical signaling module consisting of a UV-B photoreceptor and a cytoplasmic lipoxygenase mediates stomatal responses to UV-B light.

A systematic investigation of genotype-by-environment interactions for seed oil content in rapeseed revealed that BnaA02.LSH5 affects seed oil accumulation in response to light intensity.

A kinase delays Arabidopsis leaf senescence by stabilizing a phosphatase under oxidative stress, and the aging-related module may be conserved across eukaryotes.

LTD couples chlorophyll biosynthesis with light-harvesting chlorophyll a/b-binding protein transport, maintaining their stoichiometric ratio to ensure the assembly of the light-harvesting complex.

Tomato plants have a tyramine-derived phenolamide metabolic pathway regulated by the G-protein β subunit that is absent in Arabidopsis, which is essential for shoot apex growth and development.

ZmSSRP1, a subunit of the FACT histone chaperone complex, is required for RNA Polymerase II progression during transcription in maize kernel development.

Light activates psbA translation for photosystem II repair in plants by relieving repression by the psbA ORF, toggling a translational regulator bound to psbA mRNA from a repressor to an activator.

TPXL3 targets α-Aurora kinase to mitotic microtubule arrays and activates its function in bipolar spindle assembly.

Protein kinases are essential for enabling seedlings to grow against gravity, potentially by facilitating the appropriate distribution of auxin throughout the growing seedling hypocotyl.

Specific knockdown of the circular RNA Os-circANK reveals its function as a negative regulator of microRNA398b-mediated resistance to bacterial blight in rice.

A DOF transcription factor interacts with a xylem-specific transcription factor, affecting root hydraulics and drought stress responses via combined effects on xylem formation and aquaporin functions.

High throughput phenotyping of a maize multi-founder mapping population reveals genetic factors controlling dynamic photoprotection and photosystem II efficiency in maize.
