Potato, the world's most popular crop is reported to provide a food source for nearly a billion people. It is prone to a number of biotic stressors that affect yield and quality, out of which Potato Virus Y (PVY) occupies the top position. PVY can be transmitted mechanically and by sap-feeding aphid vectors. The application of insecticide causes an increase in the resistant vector population along with detrimental effects on the environment; genetic resistance and vector-virus control are the two core components for controlling the deadly PVY. Using transcriptomic tools together with differential gene expression and gene discovery, several loci and genes associated with PVY resistance have been widely identified. To combat this virus we must increase our understanding on the molecular response of the PVY-potato plant-aphid interaction and knowledge of genome organization, as well as the function of PVY encoded proteins, genetic diversity, the molecular aspects of PVY transmission by aphids, and transcriptome profiling of PVY infected potato cultivars. Techniques such as molecular and bioinformatics tools can identify and monitor virus transmission. Several studies have been conducted to understand the molecular basis of PVY resistance/susceptibility interactions and their impact on PVY epidemiology by studying the interrelationship between the virus, its vector, and the host plant. This review presents current knowledge of PVY transmission, epidemiology, genome organization, molecular to bioinformatics responses, and its effective management.

Eleven chickpea varieties were screened for their biochemical resistance to the pulse beetle (Callosobruchus chinensis L.), a serious pest of the stored pulses. The varieties were found to arrest the growth and development of C. chinensis, at grub stages which were indicated by different parameters viz., oviposition, adult emergence, weight loss, developmental period and growth index. Among the various biochemical analyzed, high growth index was observed in the varieties PKG 2 (0.61), BG 1003 (0.62), BG 1053 (0.62) and PKG 1 (0.71). Low growth index recorded in PG 3 (0.52), BGM 547 and PG 186 (0.56) may be attributed to low phenol and tannin content. Similarly the varieties PKG 1, BG 1003 and BG 1053 with less phenol, flavonoids and tannin content recorded more growth index as compared to moderate resistance varieties PG 4, PBG 1 and PG 114 PBG 1, BGM 547 and PG 114 were found to be moderately resistant and PKG 1, PKG 2, BG 1053 and BG 1003 as highly susceptible, shows the major role of trypsin inhibitor in protein resistance to C. chinensis. The highest protease activity inhibition acts as antimetabolites to C. chinensis, inhibit to the feeding of grubs as result higher trypsin content varieties showed relative resistance. The correlation between different antinutritional factors and growth index of the grub also showed a negative relationship.
