Differential response to herbivory by Helicoverpa armigera in Cajanus cajan and Cajanus platycarpus

ABSTRACT: In synchrony with deciphering the transcriptomic basis of pod borer resistance in C. platycarpus, the aim of the present work was to corroborate and understand how the leaf proteome in these two contrasting cajanus species explain the differential responses to herbivory. To the best of our knowledge this is the first investigative analysis applying proteomics to understand plant herbivore interactions in cajanus species. The study is one of the best approaches to assess cellular alterations from a multi-level perception and to enhance our understanding of resistance traits in the wild relatives.

The pigeonpea wild relative Cajanus platycarpus is resistant to Helicoverpa armigera, one of the major pests responsible for yield losses in Cajanus cajan. Deciphering the molecular mechanism underlying host plant resistance is pertinent to identify proteins that aid in the mitigation of the insect pest. The present study adopted comparative proteomics as a tool to interpret the resistance mechanism(s) in C. platycarpus vis-à-vis C. cajan during continued herbivory (up to 96 h).
