Senescence is a developmentally regulated and highly ordered sequence of events. Senescence leads to abscission of plant organs and eventually leads to death of a plant or part of it. Present study revealed that Phalaenopsis flower undergo senescence due to over activation of O2 ·−generating xanthine oxidase (XO), which consequently increases the concentrations of O2 ·− leading to enhanced oxidative damage and disturbed cellular redox environment as indicated by increased lipid peroxidation and… CONTINUE READING
