A modification of the α-chain precursor of the H+-transporting two-sector ATPase (A-3, A-4), resulting in spot migration, is triggered by both types of infection and has been detected as well as an overexpression of the mtDNA stabilising ATPase family AAA domain containing 3A (A-6) protein, whose existence has just been evidenced at transcript level [18]. Here, DNAH8 is linked to infection.
