Multiomics Analysis Reveals Multiple Metabolic Processes, Phytohormone Signaling, and the Negative Regulatory Role of ZmPP2CA11 in Maize Seedling Water Deficit Responses
Water deficit limits maize establishment, but coordinated hormonal and metabolic responses remain incompletely understood. Physiological phenotyping, RNA sequencing, widely targeted metabolomics, and phytohormone profiling were integrated to characterize B73 seedlings during PEG-induced osmotic stress and early recov...
