Remodelling of cytoskeleton and plasma membrane proteins contributes to drought sensitivity of Arabidopsis rhd2 mutant

The paper identifies proteomic and structural changes in Arabidopsis rhd2 mutant that link drought sensitivity to altered plasma membrane protein homeostasis and cytoskeleton remodeling.

Spatiotemporal distribution of ROS production, delivery and utilization in Arabidopsis root hairs

The paper uses high-resolution live-cell imaging to study ROS production and subcellular localization in Arabidopsis root hairs using three fluorescent probes.

Genetic manipulation of stress-induced mitogen-activated protein kinase modulates early stages of the nodulation process in Medicago sativa

Genetic manipulation of SIMK in alfalfa revealed that SIMK modulates root hair capacity to form infection pockets and infection threads during the early interactions between alfalfa and rhizobia.

Knockout of mitogen-activated protein kinase 3 causes barley root resistance against Fusarium graminearum.

This study shows that knocking out HvMPK3 in barley increases resistance to Fusarium graminearum through reduced hyphal growth and enhanced ROS mitigation.

Cell surface receptor kinase FERONIA linked to nutrient sensor TORC signaling controls root hair growth at low temperature linked to low nitrate in Arabidopsis thaliana

The paper identifies a molecular mechanism involving FER, ROP2, and TORC that controls root hair elongation under low temperature and nitrogen deficiency in Arabidopsis thaliana.

Arabidopsis iron superoxide dismutase 1 protects against methyl viologen-induced oxidative stress in a copper-dependent manner

This study shows that FSD1 in Arabidopsis requires copper for its antioxidative function against methyl viologen-induced oxidative stress, with chloroplast localization being essential.

AtRBOHC/RHD2 vesicular delivery to the apical plasma membrane domain during root hair development

The paper uses advanced microscopy to show that structural sterols are required for delivering GFP-RHD2 to the apical plasma membrane of root hairs during development.

Single amino acid exchange in ACTIN2 confers increased tolerance to oxidative stress in Arabidopsis der1-3 mutant

This study shows that a single amino acid change in ACTIN2 improves oxidative stress tolerance in the der1-3 mutant by altering actin dynamics and antioxidant capacity.

Cortical microtubule remodelling during strigolactone- and light-mediated growth inhibition of Arabidopsis hypocotyls

This study investigates how strigolactone signaling affects cortical microtubule organization and dynamics in Arabidopsis hypocotyls under light and dark conditions.

The interplay of HSP90s with YDA regulates main body axis formation during early embryogenesis in Arabidopsis

This study identifies HSP90s and YDA as regulators of early Arabidopsis embryo development through epigenetic control of WOX2 and WOX8 gene expression.

FSD1: a plastidial, nuclear and cytoplasmic enzyme relocalizing to the plasma membrane under salinity

This study investigates the subcellular localization and function of FSD1, an SOD in Arabidopsis, showing its role in seed germination and salt stress tolerance through plasma membrane relocalization.

Cytokinin fluoroprobe and receptor CRE1/AHK4 localize to both plasma membrane and endoplasmic reticulum

The paper shows cytokinin receptors and fluoroprobes localize to both plasma membrane and endoplasmic reticulum, suggesting multiple perception sites for cytokinin signaling.

Environment and HSP90 modulate MAPK stomatal developmental pathway

The paper shows that HSP90s modulate the YODA-MAPK pathway to control stomatal development and density in response to environmental stress.
