Nduction of Systemic Resistance in Rice by Pseudomonas Fluorescent Against Rice Root Knot Nematode Meloidogyne Graminicola
Year: 2012
Type: article
Abstract: Induction ofdefense enzymes phenol, peroxidase (PO), polyphenol oxidase (PPO),phenyl ammonia lyase (PAL), super oxide dismutase (SOD) and chitinase by Pseudomonasfluorescens isolate Pf1, against challenge inoculation of Meloidogynegraminicola in rice was studied in vitro. The activity of phenol,PO,PPO, PAL and chitinase was higher in the bacterized rice plants. Theanalysis of isoform profiles revealed unique PO, PPO and SOD isoforms inducedin plants treated with P. fluorescens. The present study implies earlierand higher accumulation of phenols and defense enzymes viz., PO, PPO,PAL and chitinase in rice root tissue resulting in significant reduction innematode infection.
