CHH demethylation of the BcMAM1 promoter contributes to cold tolerance in autotetraploid wucai (Brassica campestris L.)
UncategorizedAbstractPolyploidization has long been recognized as a driving force in plant adaptation to adverse environments. Chilling injury poses a major challenge to global crop production, and the regulatory hierarchies that govern cold adaptation in polyploid crops are unexplored. Here, we show that tetraploid…
How to Assemble an Interdisciplinary Dream Team
Blog, Featured Article 1Understanding interdisciplinarity
Interdisciplinary science is on the rise, and globally, scientists have begun to appreciate the importance of integrating multiple disciplines for solving fundamental problems (Sun et al., 2021). However, interdisciplinary research is still a topic of confusion, and…
Paradoxical energetics in the polar diatom Fragilariopsis cylindrus exposed to extreme low light
UncategorizedAbstractIt is generally considered that Arctic diatoms endure total darkness during polar winters by shifting to a hypometabolic state based on internal reserve mobilization. They can nonetheless rapidly initiate under-ice blooms at extreme low-light levels in early spring. The limits and mechanisms…
Convergent evolution of an oxidative damage tolerance mechanism preserves replication fidelity in plant organellar DNA polymerases
UncategorizedAbstractPlant mitochondria and chloroplasts are sources of reactive oxygen species (ROS) that trigger oxidative DNA lesions. Among these, 8-oxo-7,8-dihydroguanine (8-oxodG) is particularly mutagenic because it exhibits ambiguous base pairing, as DNA polymerases efficiently incorporate adenine opposite…
An investigation of the dual mechanism of uORF-mediated regulation of GGP1 expression and the effects on drought stress in cotton
UncategorizedAbstractUpstream open reading frames (uORFs) are intrinsic regulatory elements that fine-tune gene expression at the translational level without altering genomic sequences or protein structures. Here, we targeted the conserved uORF that resides in the 5'-untranslated region (5'-UTR) of a GDP-galactose…
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,…
