Review. Signalling pathways underlying nitrogen-dependent changes in root system architecture: from model to crop species (J. Exp. Bot.)

Nitrogen (N) is one of the seventeen essential nutrients for a plant to complete its life cycle and is one of the most important determinants of productivity of various crops globally. Nitrate (NO3‑) and ammonium (NH4+) are the major plant-available forms of N. The spatiotemporal heterogeneity of N…

Roles for CHROMATIN REMODELING 4 in Arabidopsis floral transition (Plant Cell)

The time at which flowers appear is critical for plant reproductive success. As such, the vegetative…

The embryo sheath is an anti-adhesive structure that facilitates cotyledon emergence during germination in Arabidopsis ($) (Curr. Biol.)

The embryo sheath is a glycoprotein structure formed during seed maturation in Arabidopsis thaliana.…

“The secret is how to die!”: CPK1 controls cell death via phosphorylation of ORE1 (Plant Cell)

Cell death, like all other cellular processes, is controlled by a highly complex signaling network. A…

A feedforward loop controls vascular regeneration and tissue repair through local auxin biosynthesis (Plant Cell)

Plant cells are entrapped in rigid cell walls, so morphogenesis relies on asymmetric cell division (ACD)…

Mars1 kinase signaling in the chloroplast unfolded protein response (eLIFE)

In stressful situations, such as high light and nutrient scarcity, the chloroplast may experience increased…

The cis-regulatory codes of response to combined heat and drought stress (bioRxiv)

As sessile organisms, plants must not only respond to a single stress, but multiple stresses at the same…

March 27, 2020/by Tatsuya Nobori

A plant kinase exploited by a bacterial effector (bioRxiv)

Pathogens have evolved a suite of effector proteins that are secreted into plants and aid successful…

Evidence for physiological seed dormancy cycling in the woody shrub Asterolasia buxifolia and its ecological significance in fire‐prone systems ($) (Plant Biol.)

Physiologically dormant seeds shift between dormancy (i.e., unable to germinate), conditional dormancy…

Update: How plants sense and respond to stressful environments (Plant Phys)

A longstanding question in plant science is how plants “know” that they are under threat. The identification…
