Defense transcriptome profiling of Allium cepa post infection with Alternaria porri. Allium cepa cultivar:Arka Kalyan

Purple blotch (PB) caused by Alternaria porri is a major disease in all onion growing countries of the world. In India, it is particularly devastating causing yield losses that range from 2.5% to 90%. The molecular mechanism underlying the interaction between the host and the pathogen is still unclear. Here we present the dynamic transcriptome profiling of Allium cepa post infection with Alternaria porri to understand the mechanism of resistance response.
