The optimization of crop response to climatic stress through modulation of plant stress response mechanisms. Opportunities for biostimulants and plant hormones to meet climate challenges. [PDF]

New Phytol
Summary This review discusses the use of agronomic management practices to enhance crop stress resilience to climate stress through the modulation of natural plant growth regulatory pathways. The use of biostimulants or plant hormones to improve crop resilience is subject to strict regulatory oversight if changes in the regulation of plant growth are ...

Parasitic Plant-Host Interactions: Molecular Mechanisms and Agricultural Resistance Strategies. [PDF]

Adv Sci (Weinh)
Parasitic plants devastate global agriculture through sophisticated molecular interactions with host crops. This review synthesizes current understanding of parasitic plant‐host interactions, from strigolactone‐mediated germination and haustorium formation to host defense mechanisms.

In vitro dynamic and quantitative monitoring of strigolactone-signaling complex formation by time-resolved FRET. [PDF]

Plant J
We developed a new in vitro method using time‐resolved FRET to evaluate the dynamic activation of the strigolactone (SL) receptors. This system was used to gain deeper insights into the molecular mechanism of SL‐signaling complex formation and to detect naturally occurring SLs.

A Reactive Antagonist Strategy: Cysteine-Directed Covalent Molecular Glue in Plant Hormone Receptor Regulation. [PDF]

Adv Sci (Weinh)
The plant hormone jasmonate is perceived by COI1‐JAZ co‐receptors comprising a single F‐box protein COI1 and multiple JAZ repressors with overlapping functions, complicating genetic analysis. We present a reactive antagonist (RA) strategy that selectively promotes COI1 binding to a cysteine‐engineered JAZ variant while blocking wild‐type JAZs, enabling

Ectopic sodium channel expression decreases excitability of Drosophila Kenyon cells. [PDF]

J Physiol
Abstract figure legend: We tested the effects of expressing the bacterial voltage‐gated sodium channel NaChBac in the Kenyon cells of the Drosophila memory centre, the mushroom body. NaChBac expression decreases expression of endogenous voltage‐gated sodium channels (left), reduces action potential firing (upper) and prevents learning (lower). However,

A combinatorial TIR1/AFB–Aux/IAA co-receptor system for differential sensing of auxin [PDF]

, 2012
The plant hormone auxin regulates virtually every aspect of plant growth and development. Auxin acts by binding the F-box protein transport inhibitor response 1 (TIR1) and promotes the degradation of the AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA ...

Pharmacological strategies for manipulating plant Ca2+ signalling [PDF]

, 2018
Calcium is one of the most pleiotropic second messengers in all living organisms. However, signalling specificity is encoded via spatio-temporally regulated signatures that act with surgical precision to elicit highly specific cellular responses.
