The increase in leaf stearate in fab2 varies developmentally, and the largest increase occurrs in young leaves, where stearate accounts for almost 20% of total leaf fatty acids. The fatty acid composition of leaf lipids isolated from the fab2 mutant shows increased stearate in all the major glycerolipids of both the chloroplast and extrachloroplast membranes. Although the stearate content is increased, the fab2 mutant still contains abundant amounts of 18:1, 18:2, and 18:3 fatty acids. The altered 18:1 fatty acid content in the fab2/ssi2 mutants has an impact on SA- and JA-mediated defense signaling. The mutants result in hyper-resistance to green peach aphid and antibiosis activity in petiole exudates.
