GABA promotes peroxisome proliferation in Triticum monococcum leaves.

ABSTRACT: Although peroxisomes are integral for both primary and secondary metabolism, how developmental changes affect activity of peroxisomes remains poorly understood. Here, we used published RNA-seq data to analyze the expression patterns of genes encoding 21 peroxisome metabolic pathways at successive developmental stages of Zea mays and Oryza sativa. Photorespiration was the most represented pathway in adult leaf relative to the juvenile stages. Components of reactive oxygen species (ROS)/reactive nitrogen species (RNS) metabolism, NADPH regeneration, and catabolism of polyamines were also enriched at later stages of leaf differentiation. The most commonly upregulated gene in differentiated leaves across all datasets of both species was BETAINE ALANINE DEHYDROGENASE (BA
