Abstract excerpt

Manganese (Mn) toxicity in acidic or waterlogged soils severely impacts crop productivity. Although high-Mn stress triggers Ca2+ signals that regulate Mn homeostasis, the mechanism generating these signals remains unclear. Here, we show that the cyclic nucleotide-gated channel CNGC11/12 are essential for Mn tolerance, as cngc11/12 mutants exhibited hypersensitivity to Mn and cngc12 mutant showed reduced Ca2+...
