Abstract Calcium (Ca2+) is an essential macronutrient for plant growth and defence, yet the molecular mechanisms regulating its uptake from soil remain largely undefined. Through bioinformatics and electrophysiological screening, we identified a group of plant-specific proteins, named the IONIC CURRENT FAMILY A (ICAs), which confer Ca2+-permeable non-selective cation channel (CNCC) activities in heterologous systems.
Abstract Autophagy and apoplastic ascorbic acid (AsA) play important roles in plant drought tolerance. However, the trans-plasma membrane transport of AsA and its association with autophagy during drought stress are unclear. Here we report an AsA-induced autophagy pathway in plants, wherein plasma-membrane-located cytochrome b561 and DOMON domain (CYBDOM) proteins play positive roles.
Abstract Pathogen-associated molecular patterns (PAMPs) activate innate immunity in both animals and plants. Although calcium has long been recognized as an essential signal for PAMP-triggered immunity in plants, the mechanism of PAMP-induced calcium signalling remains unknown1,2. Here we report that calcium nutrient status is critical for calcium-dependent PAMP-triggered immunity in plants.
