Biochemical mechanism of resistance in some Brassica genotypes against Lipaphis erysimi (Kaltenbach) (Homoptera: Aphididae)
*Corresponding author E-mail : [email protected] INTRODUCTION The genus Brassica comprises an important group of cultivated vegetable and oilseed crops and have great economic importance worldwide. The cultivated species of Brassica include cabbage, cauliflower, kale, broccoli, Brussels sprouts, turnip, swede, oilseed rape, various mustards and other leafy vegetables (Hong et al. 2008). As oils...
متن کاملInfluence of PGRs on carbohydrate content in Lipaphis erysimi (Kalt.).
Six compounds (IBA, chlorogenic acid, cytokinine, GA3, alar B-9 and maleic hydrazide) belonging to four different categories of plant growth hormones were used to study their effect on carbohydrate content in L. erysimi. The second instar nymphs (48 hr old) were given both dipping and leaf surface treatment with 1024 ppm concentration of compounds for two time intervals i.e. 48 and 96 hr. The c...
متن کاملDevelopment of transgenic Brassica juncea lines for reduced seed sinapine content by perturbing phenylpropanoid pathway genes
Sinapine is a major anti-nutritive compound that accumulates in the seeds of Brassica species. When ingested, sinapine imparts gritty flavuor in meat and milk of animals and fishy odor to eggs of brown egg layers, thereby compromising the potential use of the valuable protein rich seed meal. Sinapine content in Brassica juncea germplasm ranges from 6.7 to 15.1 mg/g of dry seed weight (DSW) whic...
متن کاملDevelopment of PR genes panel for screening aphid-tolerant cultivars in Brassica juncea
The exorbitant yield loss incurred by Indian farmers every year (10-90%) in rapeseed-mustard (Brassica juncea) is chiefly attributed to the progressive infestation of mustard fields by Lipaphis erysimi (Kalt.), a major insect pest belonging to the family of Homoptera. Currently there are no successful tolerant cultivars developed by conventional means in Brassica juncea with systemic plant resp...
متن کاملFunctional characterization of Rorippa indica defensin and its efficacy against Lipaphis erysimi
Rorippa indica, a wild crucifer, has been previously reported as the first identified plant in the germplasm of Brassicaceae known to be tolerant towards the mustard aphid Lipaphis erysimi Kaltenbach. We herein report the full-length cloning, expression, purification and characterization of a novel R. indica defensin (RiD) and its efficacy against L. erysimi. Structural analysis through homolog...
