MAP3Kinase-dependent SnRK2-kinase activation is required for abscisic acid signal transduction and rapid osmotic stress response. [PDF]

, 2020
Abiotic stresses, including drought and salinity, trigger a complex osmotic-stress and abscisic acid (ABA) signal transduction network. The core ABA signalling components are snf1-related protein kinase2s (SnRK2s), which are activated by ABA-triggered ...

Control of abscisic acid synthesis [PDF]

Journal of Experimental Botany, 2000
The abscisic acid (ABA) biosynthetic pathway involves the formation of a 9-cis-epoxycarotenoid precursor. Oxidative cleavage then results in the formation of xanthoxin, which is subsequently converted to ABA. A number of steps in the pathway may control ABA synthesis, but particular attention has been given to the enzyme involved in the oxidative ...

SnapShot: Abscisic Acid Signaling

Cell, 2017
Abscisic acid is a key phytohormone produced in response to abiotic stress conditions and is an activator of abiotic stress resistance mechanisms and a regulator during diverse developmental stages in plants. This SnapShot explores how ABA signaling operates and coordinates resistance during stress responses and modulates plant development.

Abscisic Acid and Stomatal Regulation [PDF]

Plant Physiology, 1972
The closure of stomata by abscisic acid was examined in several species of plants through measurements of CO(2) and H(2)O exchange by the leaf. The onset of closure was very rapid, beginning at 3 minutes from the time of abscisic acid application to the cut base of the leaf of corn, or at 8 or 9 minutes for bean, Rumex and sugarbeet; rose leaves were ...

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

Advanced Science, EarlyView.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...

MaMADS2 repression in banana fruits modifies hormone synthesis and signalling pathways prior to climacteric stage

BMC Plant Biology, 2018
Background While the role of ethylene in fruit ripening has been widely studied, the contributions of additional plant hormones are less clear. Here we examined the interactions between the transcription factor MaMADS2-box which plays a major role in ...

Domestication of Tartary Buckwheat Shaped a Regulatory Module for Seedling Salt Tolerance by Targeting the Magnesium Transporter Gene FtMGT2

Advanced Science, EarlyView.
Domestication of Tartary buckwheat is selected for a salt tolerance mechanism involving the magnesium transporter FtMGT2. Its expression is controlled by the FtAGL16‐FtMYB15L module, which is stabilized under salt stress through a competitive interaction that blocks its degradation by the E3 ligase FtBRG1, ultimately boosting Na⁺ efflux and plant ...

Improvement of seed germination of Fagus orientalis Lipsky [PDF]

, 2003
This thesis was seeking two main approaches for improvement of seed germination of oriental beech, a timber producing species in Hyrcanian forests in northern Iran. Germination behavior of beechnuts was enhanced either by decreasing the dormancy breakage

A Statistical Mechanics Model to Decode Tissue Crosstalk During Graft Formation

Advanced Science, EarlyView.
We introduce a statistical mechanics framework to decode the genomic crosstalk governing plant grafting. By integrating evolutionary game theory with transcriptomics, we reconstruct idopNetworks (informative, dynamic, omnidirectional, and personalized networks) that map scion–rootstock interactions.
