Brassinosteroid-Activated BRI1-EMS-SUPPRESSOR 1 Inhibits Flavonoid Biosynthesis and Coordinates Growth and UV-B Stress Responses in Plants
UV-B light BES1 brassinosteroids flavonoids
2023/12/21
Ultraviolet B (UV-B) light is a potential stress factor in plants, but how plants coordinate growth and UV-B stress responses is not well understood. Here we report that brassinosteroid (BR) signaling...
Peroxisomes as redox-signaling nodes in intracellular communication and stress responses
peroxisomes stress responses DNA repair systems CAT3 GSNOR
2023/12/6
Redox compartmentalization in organelles is an effective evolutionary strategy (Box 1; Jones and Go, 2010). From an evolutionary perspective, peroxisomes, originating from the endoplasmic reticulum (E...
A MRG-operated chromatin switch at SOC1 attenuates abiotic stress responses during the floral transition
stress responses MORF-RELATED GENE (MRG) Arabidopsis plant fitness endogenous signals reproductive success
2023/12/1
Plants react to environmental challenges by integrating external cues with endogenous signals to optimize survival and reproductive success. However, the mechanisms underlying this integration remain ...
The Ca2+ sensor proteins CML37 and CML42 antagonistically regulate plant stress responses by altering phytohormone signals
Jasmonates Abscisic acid Drought Herbivory Necrotrophic pathogenes Defense Calcium Glucosinolates Spodoptera littoralis Alternaria brassicicola
2023/12/1
A transient increase in the cytosolic calcium concentration is one of the first reactions that can be measured in plant cells upon abiotic as well as biotic stress treatments. These calcium signals ar...
H+-ATPases in Plant Growth and Stress Responses
acid growth modulation ion transport protein phosphorylation protonpump stress response vacuolar acidification
2023/11/28
H+-ATPases, including the phosphorylated intermediate–type (P-type) and vacuolar-type (V-type) H+-ATPases, are important ATP-driven proton pumps that generate membrane potential and provide proton mot...
Abscisic acid signaling and crosstalk with phytohormones in regulation of environmental stress responses
Abscisic acid Phytohormones cross talk Seed germination Stress regulation Stress signaling Stomatal regulation
2023/11/28
Frequently changing environmental conditions pose unwarranted threat to plants life and impose serious penalties in terms of arrested growth, metabolism and ultimately the yield. Being rooted, plants ...
Targeted and untargeted metabolomics reveals deep analysis of drought stress responses in needles and roots of Pinus taeda seedlings
drought tolerance phytohormones fatty acids neurotransmitters sugars amino acids organic acids ?avenoids and terpenoids
2023/11/16
Drought stress is one of major environmental stresses affecting plant growth and yield. Although Pinus taeda trees are planted in rainy southern China, local drought sometime occurs and can last sever...
APC/CCDC20 targets SCFFBL17 to activate replication stress responses in Arabidopsis
APC/C DNA replication stress SCF WEE1 ubiquitination
2023/11/16
DNA replication stress threatens genome stability and affects plant growth and development. How plants resolve replication stress is poorly understood. The protein kinase WEE1-mediated cell cycle arre...
Jasmonic acid and salicylic acid modulate systemic reactive oxygen species signaling during stress responses
long-distance arabidopsis acclimation combination ethylene light npr1
2023/11/16
Plants can send long-distance cell-to-cell signals from a single tissue subjected to stress to the entire plant. This ability is termed “systemic signaling” and is essential for plant acclimation to s...
Roles of the SPL gene family and miR156 in the salt stress responses of tamarisk (Tamarix chinensis)
abscisic acid insensitivity grey poplar isotope discrimination stomatal conductance transpiration unsaturation
2024/2/27
Accumulating evidences show that SPLs are crucial regulators of plant abiotic stress tolerance and the highly conserved module miR156/SPL appears to balance plant growth and stress responses. The halo...
