Knockdown of Adenosine 5'-Triphosphate-Dependent Caseinolytic Protease Proteolytic Subunit 6 Enhances Aluminum Tolerance in Peanut Plants (Arachis hypogea L.).

ABSTRACT: Aluminum (Al³⁺) toxicity in acidic soils reduces root growth and can lead to a considerable reduction in peanut plants (Arachis hypogea L.). The caseinolytic protease (Clp) system plays the key role in abiotic stress response. However, it is still unknown whether it is involved in peanut response to Al³⁺ stress. The results from this study showed that Adenosine 5'-triphosphate (ATP)-dependent caseinolytic protease proteolytic subunit 6 (AhClpP6) in peanut plants was involved in the Al³ stress response through its effects on leaf photosynthesis. The AhClpP6 expression levels in the leaf and stem significantly increased with the Al³⁺ treatment times. Knockdown AhClpP6 peanut lines accumulated significantly more Al³⁺
