The triploid block, which prevents interploidy hybridizations in flowering plants, is characterized by a failure in endosperm development, arrest in embryogenesis, and seed collapse. Many genetic comp...
Proteins are intimately involved in executing and controlling virtually all cellular processes. To understand the molecular mechanisms that underlie plant phenotypes, it is essential to investigate pr...
Xylem embolism spread is largely prevented by interconduit pit membranes until the majority of conduits are gas-filled

PhePLATZ1, a PLATZ transcription factor in moso bamboo (Phyllostachys edulis), improves drought resistance of transgenic Arabidopsis thaliana
ABA signaling Drought tolerance Moso bamboo PhePLATZ1
2023/11/28
Drought is one of the most serious environmental stresses. Plant AT-rich sequence and zinc-binding (PLATZ) proteins perform indispensable functions to regulate plant growth and development and to resp...
Higher leaf nitrogen content is linked to tighter stomatal regulation of transpiration and more efficient water use across dryland trees
