BACKGROUND: Chickpea (Cicer arietinum L.), a major nutritional source cultivated worldwide, is vulnerable to several abiotic and biotic stresses, including different types of soil-borne pathogens like Fusarium oxysporum f. sp. ciceri, which causes root rot disease and severely affects productivity.
METHODS AND RESULTS: In this study, putative transgenic plants were obtained with the Radish defensin (Rs-AFP2) gene through Agrobacterium tumefaciens mediated transformation using the embryo axis explants. Transgenes were confirmed in 18 putative transgenic plants with PCR-specific primers for nptII and Rs-AFP2 genes. Twelve transgenic plants were established successfully under greenhouse conditions. The T0 plants were allowed for self-pollination to obtain T1 seeds. The T1 plants, selected for Fusarium wilt assay using Fusarium oxysporum f. sp. Cicero, showed different resistance levels, from moderate to high levels in comparison to control plants (wild-type) which exhibited severe wilt symptoms.
CONCLUSION: Our results suggest the application of Radish defensins (RsAFP1/RsAFP2 genes) for improving pathogen resistance in chickpea.
