Abstract: | "Aphids are the major concern that significantly reduces the yield of crops. (E)-beta-farnesene (Ebetaf) is the principal component of the alarm pheromone of many aphids. The results of current research support the direct defense response of (E)-beta-farnesene (Ebetaf) against aphid Lipaphis erysimi (L.) Kaltenbach in Brassica juncea. Ebetaf gene was isolated from Mentha arvensis and transformed into B. juncea, showed direct repellent against aphid colonization. The seasonal mean population (SMP) recorded under field condition showed significantly higher aphid colonization in wild type in comparison to most of the transgenic lines, and shows positive correlation with the repellency of transgenic plant expressing (E)-beta-farnesene. The current research investigation provides direct evidence for aphid control in B. juncea using Ebetaf, a non-toxic mode of action" |
