Changes in metabolic profiles. a Separation of metabolic profiles for each genotype between the two environments. b Total number of varied metabolites between the two environments for each genotype and distribution of abundant metabolites for each genotype in the two locations. c Number of common varied metabolites in Acerra (Ac) and Sarno (Sa) as well genotypic specific varied metabolites in each localities. d Principal Component Analysis on changed metabolites between the two locations for each genotype (H on the left, SM in the middle, RSV on the right)
