A phenological trick and cell wall bricks toward adaptive strategies of Mimosa tenuiflora-Lopesia mimosae interaction in Caatinga environment

•Gall induction synchronizes with Mimosa tenuiflora leaf sprouting in rainy season.•The reproductive phase mismatches with gall peaks.•Gall tissue reorganization and compartmentalization buffer Caatinga hydric stresses•Pectin confers porosity to cell walls favoring water accumulation in gall tissues.•The heteromannans are potential reserve carbohydrate to the gall inducer.
