Isoleucine belongs to the subgroup of branched chain amino acids (also known as Branched-Chain Amino Acids BCAA), these amino acids serve as a substrate to synthesize many other metabolites. Like valine, leucine or isoleucine, alanine is a precursor of alcohols and other compounds, which improve the fruits’ organoleptic qualities. In addition, it is known that, in situations of abiotic stress, plants produce stress response proteins with many branched-chain amino acids, such as isoleucine. Additionally, it is a very important amino acid for which the plant obtains energy, under non-stress situations, the main energy source of the plants during the day is photosynthesis; At night the amino acids, and especially isoleucine, are the main precursors of energy generation.
