Abstract excerpt
Ca2+ signals play a crucial role in heat stress (HS) resistance. However, how Ca2+ signals are decoded and regulate the downstream targets of HS signaling remains unclear in plants. Cool-season grasses are sensitive to high-temperature conditions and should evolve distinctive heat stress response mechanisms. Here, we identified the calcium-dependent protein kinase 19 (FaCPK19), which decoded the unique Ca2+...
