| Study Title | Lipidomics analysis on Arabidopsis autophagy mutants |
| Study Summary | Autophagy is an essential cellular process in eukaryotes that degrades and recycles macromolecules and organelles. Defects in autophagy is known to affect metabolism, including the lipidome. Genetic approaches have identified a series of AuTophaGy-related (ATG) genes in Arabidopsis. In this study we used WT (ecotype Col-0) and two Arabidopsis autophagy-defective mutants, atg7 and atg9 to perform a multi-omics study on the effect of nitrogen starvation treatment, which induces autophagy. Specifically, we have quantified ~100 lipids from leaf and root tissues of WT, atg7 and atg9 mutant plants, under either autophagy-inducing conditions (-N) or normal nitrogen conditions (+N). The lipid species we quantified include: DGDG, MGDG, LPC, LPE, PE, LPG, PC, PA, PG, PI, and PS. Our study sheds lights on the understanding of the relationships between autophagy and metabolism, especially lipid metabolism. |

| Project Title: | Lipidomics analysis on Arabidopsis autophagy mutants |
| Project Summary: | We are interested in how autophagy, as an essential cellular process, affects the lipid metabolism in plants such as Arabidopsis. Specifically, we applied autophagy inducing treatments to two autophagy deficient mutants (atg7 and atg9) and WT Arabidopsis plants, and we quantified about 100 different lipids using ESI triple-quadrupole MS. The lipid species we quantified include: DGDG, MGDG, LPC,LPE, PE, LPG, PC, PA, PG, PI, and PS. |
