dc.description.abstract | Phytophthora capsici is one of the most destructive pathogens causing quick wilt (foot rot)
disease in black pepper (Piper nigrum L.) to which no effective resistance has been defined. To better
understand the P. nigrum–P. capsici pathosystem, we employed metabolomic approaches based on
flow‐infusion electrospray–high‐resolution mass spectrometry. Changes in the leaf metabolome
were assessed in infected and systemic tissues at 24 and 48 hpi. Principal Component Analysis of
the derived data indicated that the infected leaves showed a rapid metabolic response by 24 hpi
whereas the systemic leaves took 48 hpi to respond to the infection. The major sources of variations
between infected leaf and systemic leaf were identified, and enrichment pathway analysis indicated,
major shifts in amino acid, tricarboxylic acid cycle, nucleotide and vitamin B6 metabolism upon
infection. Moreover, the individual metabolites involved in defensive phytohormone signalling
were identified. RT‐qPCR analysis of key salicylate and jasmonate biosynthetic genes indicated a
transient reduction of expression at 24 hpi but this increased subsequently. Exogenous application
of jasmonate and salicylate reduced P. capsici disease symptoms, but this effect was suppressed with
the co‐application of abscisic acid. The results are consistent with abscisic acid reprogramming, salicylate
and jasmonate defences in infected leaves to facilitate the formation of disease. The augmentation
of salicylate and jasmonate defences could represent an approach through which quick wilt
disease could be controlled in black pepper. | pl_PL |
