General Information | Comment | Organism |

malfunction | downregulation of PI3K activity accelerates leaf senescence induced by methyl jasmonate (MeJA) and suppresses the activation of vacuolar H+-ATPase (VATPase) | Arabidopsis thaliana |
metabolism | PI3K type III plays a vital role in the trafficking of proteins to and from vacuoles. Interactions between VHA-B2 and PI3K are possibly promoted the translocation of VHA-B2 from the TNG to the vacuole and thus improve the assembly of V-ATPase, resulting in increased V-ATPase activity | Arabidopsis thaliana |
physiological function | pivotal role of phosphatidylinositol 3-kinase in delaying of methyl jasmonate-induced leaf senescence. Phosphatidylinositol 3-kinase (PI3K) and its product PI3P are involved in plant development and stress responses. PI3K type III plays a vital role in the trafficking of proteins to and from vacuoles. The vacuolar acidification is regulated by the PI3K-V-ATPase pathway in the methyl jasmonate-induced leaf senescence | Arabidopsis thaliana |
