V-ATPases and amino acid catabolism are strongly disturbed in the roots of autophagy mutants in Arabidopsis, impacting water use efficiency and tricarboxylic acid metabolism.

Abstract excerpt

Autophagy is essential for homeostasis and nutrient recycling. Its activity increases with aging and in response to deficiencies. The effects of defective autophagy on root metabolism have not yet been described. Addressing this question through root proteome analyses, we found that most V-ATPases were less abundant in the roots of autophagy mutants than in wild type. V-ATPases deficit, associated with lower root...
