Histological changes and differences in activities of some antioxidant enzymes and hydrogen peroxide content during somatic embryogenesis of Musa AAA cv. Yueyoukang 1
Original language description
To determine the possible involvement of oxidative stress in somatic embryogenesis of banana (Musa spp.), and provide a means to overcome the recalcitrance in embryogenesis, changes in histology, hydrogen peroxide (H2O2) content and antioxidant enzyme activities during banana somatic embryogenesis were investigated. From embryogenic cells (ECs) to early globular embryos, nearly all cells showed typical meristematic characteristics with a high nucleus/cytoplasm ratio. Cells started to lose their meristematic characteristic during later globular stage. Starch granules in cells showed spatial and temporal changes during somatic embryogenesis. POD (E.C.1.11.1.7) activity decreased significantly after transfer of ECs to the embryo regeneration medium whichwas followed by a significant increase and peaked at the late stages of embryogenesis. CAT (E.C.1.11.1.6) activity showed similar pattern, however its highest activity appeared in the ECs instead of the later embryos. On the contrary, a g
