Chickpea (Cicer arietinum L.) is a major nutritional source cultivated worldwide. Chickpea 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. The putative transgenic plants were obtained with the Radish defensin (Rs-AFP2) gene through Agrobacterium tumefaciens mediated transformation using the embryo axis explants. Transgenes were con rmed in 18 putative transgenic plants with PCR-speci c primers for nptII and Rs-AFP2 genes. Twelve transgenic plants were established successfully under greenhouse conditions. The T0 plants were allowed for selfpollination and obtained T1 seeds. The T1 plants were selected for Fusarium wilt assay using Fusarium oxysporum f. sp. ciceri. The T1 plants showed different resistance levels, from moderate to high levels. The control plants (wild-type) exhibited severe wilt symptoms after Fusarium infection.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
