Enriched KEGG pathways of differentially abundant chloroplast proteins (DACPs) in wheat seedling leaves under drought stress and exogenous ALA pretreatment. a D + A versus D; b ALA versus CK; and c, drought versus CK. The number of involved proteins in a specific pathway and corresponding p-values are shown on the right side of the column. CK, treated with 0 mg L− 1 ALA + distilled water; ALA, treated with 100 mg L− 1 ALA and distilled water; drought, treated with 0 mg L− 1 ALA without distilled water; D + A, treated with 100 mg L− 1 ALA without distilled water
