Biochemical changes induced by Mungbean yellow mosaic virus (MYMV) in mungbean [Vigna radiata (L.) Wilczek]

Abstract

In present investigation biochemical changes in mungbean induced by the Mungbean yellow mosaic virus were investigated. In biochemical parameters, protein, Total phenol and total sugar content was studied. The biochemical contents in healthy plants were analyzed at different stages i.e. 15 DAS and at 30 DAS in resistant (HUM 6, and IPM 312-9), moderately resistant (SML 1811 and AKM 12-06) and susceptible (AKM 12-14 and AKM 10-11) was also compared with infected plants of same genotypes. The protein content was more in healthy plants of resistant genotypes than moderately resistant followed by susceptible at 15 and 30 DAS. The content was found increased in infected plants than healthy plants of resistant followed by moderately resistant and susceptible at 30 DAS. The total phenol content was also maximum in resistant followed by moderately resistant and susceptible. When analyzed at 30 DAS from healthy plants of these genotypes further the content was increased in infected plants than healthy plants of resistant followed by moderately resistant and susceptible. Decreased total sugar content was recorded in resistant genotypes than moderately resistant followed by susceptible genotypes at 15 and 30 DAS.
