A New Candidate of Catalase Appears during the Germination after Priming in Naturally Aged Neem (Azadirachta indica) Seeds

Vimal Pandey and Atanu Kumar Pati

Loss of Neem (Azadirachta indica) seeds viability remarkably occurs with natural storages and related to decreased seed germination. We investigated that osmopriming induces hydrogen peroxide during germination that could be signaling molecule for germination improvement. A new catalase isozyme appeared during post-priming germination. The results show a high coordination between hydrogen peroxide and catalase and H2O2 may play a role in regulation of new catalase isozyme expression during post-priming germination of aged neem seeds.
