Description
Pigeonpea (Cajanus cajan) is a sub-tropical and tropical pulse rich in plant-based protein, carbohydrates, minerals, and vitamins. Helicoverpa armigera is the most devastating insect pest in pigeonpea. This study focussed on deciphering the molecular host plant resistance (HPR) mechanisms applied by Cajanus scarabaeoides a wild pigeonpea against insect using transcriptomic and proteomic studies. These HPR mechanisms were transferred to the cultivated pigeonpea via interspecific hybridisation, and they are stable at F2 generation. The study outcome provides a unique insight into the insect resistance mechanisms employed by C. scarabaeoides and lays the foundation for further studies and applications.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
