Structural and Functional Analysis of Groundnut bud necrosis virus (GBNV) Using Computational and Biochemical Approaches.

Groundnut bud necrosis virus (GBNV) belonging to the genus Orthotospovirus is transmitted by its vector Thrips palmi. It is a tri-segmented RNA virus that consists of L, M, and S RNA segments. We analysed the secondary structure features of GBNV proteins through various software and predicted the transmembrane helix, glycosylation, and signal peptidase sites within the GBNV protein sequences (G, G, N, NSm, and NSs).

A thioredoxin-like protein of Bemisia tabaci interacts with coat protein of begomoviruses.

Bemisia tabaci (whitefly) is the sole vector of begomoviruses, which transmits them in a persistent and circulative manner from infected to healthy plants. During this process, begomoviruses interact with various proteins in the insect vector B. tabaci that would play a specific role in the virus transmission.

Influence of Groundnut bud necrosis virus on the Life History Traits and Feeding Preference of Its Vector, Thrips palmi.

The effect of Groundnut bud necrosis virus (GBNV) infection on the life history traits of its vector, Thrips palmi, and its feeding preference on GBNV-infected plants were studied. A significant difference was observed in the developmental period (first instar to adult) between the GBNV-infected and healthy thrips, wherein the developmental period of GBNV-infected thrips was decreased. However, there was no effect on the other parameters such as preadult mortality, adult longevity, and fecundity.

Detection and Localization of Wolbachia in Thrips palmi Karny (Thysanoptera: Thripidae).

Thrips palmi Karny is a globally distributed polyphagous agricultural pest. It causes huge economic loss by its biological behaviors like feeding, reproduction and transmission of tospoviruses. Since T.

Elimination of Arsenophonus and decrease in the bacterial symbionts diversity by antibiotic treatment leads to increase in fitness of whitefly, Bemisia tabaci.

Bemisia tabaci is an invasive agricultural pest with more than 24 genetic groups harboring different bacterial endosymbionts categorized into obligatory and facultative endosymbionts. Arsenophonus is one of the facultative endosymbionts prevalent in B. tabaci of Indian sub-continent.
