Plant defense induced in in vitro propagated banana (Musa paradisiacd) plantletsby Fusarium derived elicitors

摘要

Perception of microbial signal molecules is part of the strategy evolved by plants to survive attacks by potential pathogens. To gain a more complete understanding of the eary signaling events involved in these responses, we used fungal components ofFusarium under in vitro condition and checked the rise in signal molecule, salicylic acid (SA), and marker enzymes in defense reactions against the pathogen. SA level increased by 21 folds in elicitoi treated plantlets as compared to that of control plantlets and there was marked increase in phenylalanine ammonia-lyase(PAL), peroxidase(POX), polyphenol oxidase(PPO) along with higher total phenolic content Present results indicated that use of fungal components had successfully induced systemic resistance in in vino cultured banana plantlets.
