physiological function | Dgd1 mutants have a greater than 90% reduction in digalactosyldiacylglycerol content, reduced photosynthesis, and altered chloroplast morphology. Mutant plants show an extremely short inflorescence stem. Phloem cap cells are lignified and jasmonic acid-responsive genes are highly upregulated under normal growth conditions. The coronative insensitive1 Dgd1 and allene oxide synthase Dgd1 double mutants no longer exhibit the short inflorescence stem and lignification phenotypes but still have the same lipid profile and reduced photosynthesis as Dgd1 single mutants. Dgd1 mutants display increased levels of jasmonic acid, jasmonic acid-isoleucine, 12-oxo-phytodienoic acid, and arabidopsides. Jasmonic acid biosynthesis in Dgd1 mutants is initially activated through the increased expression of genes encoding 13-lipoxygenases and phospholipase A-Ig3 (At1g51440), and is sustained by further increases in 13-lipoxygenase and allene oxide cyclase mRNA and protein levels | Arabidopsis thaliana |
