As a universal process in multicellular organisms, including animals and plants, cells usually
emit danger signals when suffering from attacks of microbes and herbivores, or physical …

Abscisic acid (ABA) regulates numerous developmental processes and adaptive stress
responses in plants. Many ABA signaling components have been identified, but their …

Rice is sensitive to cold and can be grown only in certain climate zones. Human selection of
japonica rice has extended its growth zone to regions with lower temperature, while the …

Heterotrimeric G proteins (Gα, Gβ/Gγ subunits) constitute one of the most important
components of cell signaling cascade. G Protein Coupled Receptors (GPCRs) perceive …

In animals, heterotrimeric G proteins, comprising α-, β-and γ-subunits, perceive extracellular
stimuli through cell surface receptors, and transmit signals to ion channels, enzymes and …

In plants, G proteins modulate signaling by the stress hormone, abscisic acid (ABA). We
identify and characterize two novel Arabidopsis proteins that show homology to an orphan …

Photosynthesis is regulated by environmental factors as well as endogenous sugar signals.
Whereas light‐driven sugar biosynthesis is essential for terrestrial organisms, as well as …

Previously, it has been shown that Arabidopsis thaliana leaves exposed to high light
accumulate hydrogen peroxide (H2O2) in bundle sheath cell (BSC) chloroplasts as part of a …

A fascinating feature of plant growth and development is that plants initiate organs
continually throughout their lifespan. The ability to do this relies on specialized groups of …

Investigators studying G protein–coupled signaling—often called the best-understood
pathway in the world owing to intense research in medical fields—have adopted plants as a …
