Global warming intensifies extreme heat events, threatening crop reproduction by impairing pollen development, germination, and tube growth. However, the mechanisms underlying responses remain elusive. The actin cytoskeleton actin-binding proteins (ABPs) are crucial in these processes, yet their roles under stress poorly understood. Here, we identify a mutant, germination sensitive to LatB (pgsl1), via forward genetic screening. PGSL1 encodes heat-stable, plant-specific ABP that binds...
Abstract To gain insight into the molecular mechanisms underpinning tobacco ( Nicotiana tabacum ) tolerance to drought stress, we integrated anatomical, physiological, and proteomic analyses of drought-tolerant (Yuyan6, [Y6]) -sensitive (Yunyan87 [Y87]) varieties. In comparison Y87, Y6 exhibited higher water retention capability, improved photosynthetic performance, delayed leaf-senescence, stable leaf ultrastructure, a stronger antioxidant defense, lesser ROS accumulation when subjected...
Root hair is a polarly elongated single-celled tissue that derives from root epidermal cell for uptake of water and nutrient the surrounding environment. Previous reports have demonstrated short periods high pH inhibited extension, however, effects long-term high-pH treatment on growth hairs still unclear. Here, we reported duration elongation significantly prolonged with increasing external pH, which counteracts effect decreasing rate ultimately produces longer hairs, whereas loss...
Abstract Double fertilization in many flowering plants (angiosperms) often occurs during the hot summer season, but mechanisms that enable angiosperms to adapt specifically high temperatures are largely unknown. The actin cytoskeleton is essential for pollen germination and polarized growth of tubes, yet how this process responds remains unclear. Here, we reveal thermal stability 11 Arabidopsis (Arabidopsis thaliana) actin-depolymerizing factors (ADFs) significantly different: ADFs...
