Data on docking of phytoconstituents of Actinidia deliciosa on dengue viral targets.

ABSTRACT: Major Phytoconstituents of Actinidia deliciosa were explored for their anti-viral potential against dengue virus (DENV). The docking of these phytoconstituents was performed on 7 viral targets- 4 DENV non structural protein (NS5-SAM binding domain, NS5 RdRp domain, NS3 helicase & NS2B-NS3 protease) and 3 DENV structural proteins (Envelope protein-?-OD domain, stem domain & Domain III). The analysis was done on the basis of binding affinity, type of interactions (bond type and distance) and interaction with amino acids significant in viral replication. The top 5 phytoconstituents with best docking score have been reported.

Project description:Background and aimsDioecism characterizes many crop species of economic value, including kiwifruit (Actinidia deliciosa). Kiwifruit male sterility occurs at the microspore stage. The cell walls of the microspores and the pollen of the male-sterile and male-fertile flowers, respectively, differ in glucose and galactose levels. In numerous plants, pollen formation involves normal functioning and degeneration timing of the tapetum, with calcium and carbohydrates provided by the tapetum essential for male fertility. The aim of this study was to determine whether the anther wall controls male fertility in kiwifruit, providing calcium and carbohydrates to the microspores.MethodsThe events occurring in the anther wall and microspores of male-fertile and male-sterile anthers were investigated by analyses of light microscopy, epifluorescence, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling (TUNEL assay) and transmission electron microscopy coupled with electron spectroscopy. The possibility that male sterility was related to anther tissue malfunctioning with regard to calcium/glucose/galactose provision to the microspores was also investigated by in vitro anther culture.Key resultsBoth tapetum and the middle layer showed secretory activity and both degenerated by programmed cell death (PCD), but PCD was later in male-sterile than in male-fertile anthers. Calcium accumulated in cell walls of the middle layer and tapetum and in the exine of microspores and pollen, reaching higher levels in anther wall tissues and dead microspores of male-sterile anthers. A specific supply of glucose and calcium induced normal pollen formation in in vitro-cultured anthers of the male-sterile genotype.ConclusionsThe results show that male sterility in kiwifruit is induced by anther wall tissues through prolonged secretory activity caused by a delay in PCD, in the middle layer in particular. In vitro culture results support the sporophytic control of male fertility in kiwifruit and open the way to applications to overcome dioecism and optimize kiwifruit production.
