Transcription Factor TabZIP12 Orchestrates the ABA Signaling Pathway to Regulate Drought Tolerance in Wheat (Triticum aestivum L.)
UncategorizedAbstractDrought-induced osmotic stress severely compromises crop yield productivity and threatens global food security. This study reports TabZIP12, a wheat bZIP transcription factor, in regulating osmotic stress tolerance. Under drought and abscisic acid (ABA) treatment, TabZIP12 expression was significantly…
ABA and Stomatal Biology: From Transcriptional and Biosynthesis to Multicellular Coordination Across Cell Types
UncategorizedAbstractAbscisic acid (ABA) was first identified in plants over six decades ago and is now recognized as one of the central phytohormones in plants, regulating growth, development, and physiological adaptation to environmental changes. In this Centennial Update, we use two influential ABA-related articles…
The VvmiPEP397-VvmiR397-VvLAC14 module regulates salt tolerance in grapevine
UncategorizedAbstractSoil salinization poses a significant constraint to the sustainable development of the grape industry. Although miR397 is known to be involved in plant stress responses, its regulatory mechanism in grapevine salt tolerance remains unclear. In this study, we systematically deciphered the role…
A HAT7/ATHB13/Brassinosteroid signaling module mediates growth of laticifer cells in Euphorbia lathyris
UncategorizedAbstractLaticifers, the coenocytic cells responsible for latex production, represent one of the most extreme examples of continuous and polarized growth in plants. Their unique architecture, extending over large distances, requires tight coordination between wall extensibility, cytoplasmic organization,…
Lysine biosynthesis integrates carbon availability and energy homeostasis under fluctuating CO2
UncategorizedAbstractLysine metabolism connects amino acid biosynthesis with mitochondrial respiration through coordinated synthesis and degradation pathways that interface with the tricarboxylic acid (TCA) cycle and the mitochondrial electron transport chain (mETC). The critical role of this pathway is underscored…
Transcription factor ANAC087 coordinates symplastic Cd exclusion and apoplastic Cd sequestration to enhance cadmium resistance in Arabidopsis thaliana
UncategorizedAbstractCadmium (Cd) exclusion and sequestration are vital mechanisms for plant survival under heavy metal stress, yet the upstream regulatory networks governing these coordinated processes remain poorly understood. In this study, we identified the NAC transcription factor ANAC087 as a key positive regulator…
OsGSK2-OsBSK3 feedback loop controls rice BR signaling
UncategorizedAbstractBrassinosteroids (BRs) are essential plant hormones that regulate growth and development, including leaf angle regulation and grain size determination. Maintaining appropriate BR signaling requires precise coordination between pathway activation and attenuation. BR signaling is initiated by OsBRI1…
Glycogen phosphorylase and phosphoenolpyruvate synthase are key metabolic nodes for high-light acclimation in cyanobacteria
UncategorizedAbstractBalancing energy supply from photosynthetic light reactions with downstream metabolic demand is critical for preventing photosystem damage. Although energy-dissipation mechanisms involving remodeling of photosystems are well known, the role of downstream metabolic routes in energy dissipation…
The energy sensor SnRK1 promotes starvation-induced autophagosome formation by modulating ATG13a phosphorylation in Arabidopsis
UncategorizedAbstractIn eukaryotes, autophagy is an evolutionarily conserved cellular degradation and recycling process that is tightly associated with cellular nutrient status. The energy sensor SNF1-RELATED KINASE 1 (SnRK1) is thought to sense nutrient starvation and induce autophagy, but how it regulates autophagosome…
