Abstract EN
-Plant chitinases have been of particular interest since they are known to be induced upon pathogen invasion.
Inoculation of Piper colubrinum leaves with the foot rot fungus, Phytophthora capsici leads to increase in chitinase activity.
A marked increase in chitinase activity in the inoculated leaves was observed, with the maximum activity after 60 h of inoculation and gradually decreased thereafter.
Older leaves showed more chitinase activity than young leaves.
The level of chitinase in black pepper (Piper nigrum L.) upon inoculation was found to be substantially high when compared to P.
colubrinum.
RT–PCR using chitinase specific primers revealed differential accumulation of mRNA in P.
colubrinum leaves inoculated with P.
capsici.
However, hyphal extension assays revealed no obvious differences in the ability of the protein extracts to inhibit growth of P.
capsici in vitro.
