Prangolarin is a chemical facilitator for the enhanced development of the infection process in the epicarp of Citrus limon by Penicillium digitatum.

 

The application of a water suspension of conidia of P. digitatum caused complete green mould symptoms to develop on 65% of wounded lemon epicarps after 4 d. However, wounded lemon epicarps, exhaustively washed with water, exhibited only 2% green mould symptoms when inoculated with spores of P. digitatum. However, when a comparable amount of isolated lemon epicarp oil was topically applied to the washed wounds, 92% of the inoculated wound sites developed green mould symptoms. It is suggested that some component of the lemon epicarp oil is essential for the development of P. digitatum in epicarp tissues and that the fungal facilitating factor(s) could be present in the lemon epicarp oil. One promoting factor from the oil was isolated by bioassay-guided fractionation and was identified as prangolarin by spectrometric analysis. Isolated prangolarin enhanced disease development by P. digitatum on wounded epicarps of lemons.
