Differential Gene Expression in Incompatible Interaction between Phytophthora capsici and Capsicum annuum

Abstract:

Pepper (Capsicum annuum L) is an important economic vegetable crop in worldwide, however the pepper blight caused by Phytophthora capsici has been epidemic in many countries. Little is known about pepper–oomycete interactions at the molecular and genetic levels. The objective of this study was to identify transcriptionally regulated genes during an incompatible interaction between pepper and P.capsici using cDNA-AFLP technique. A total of 100 transcript-derived fragments (TDFs) were sequenced. The result revealed that 84 (88.0%) TDFs produced specific sequences, among which 19 TDFs had relatively clear functions in various categories. Seven TDFs (9.5%) shared high similarities with defense- or stress-related proteins. The TDFs identified in this study will serve as candidates for further studies to determine their functions and dissect the molecular networks involved in the pepper- P.capsici interactions.
