Ethanolic extracts from leaf, stem and root parts of Jatropha curcas which belongs to the family Euphorbiaceae were evaluated for potential antifungal activity against fungal pathogen of vegetable beans. The present study is aimed at evaluating the in-vitro antifungal activity of ethanolic extracts of Jatropha curcas plant against Alternaria alternata, Fusarium pallidoroseum, Curvularia lunata and Macrophomina phaseolina. The leaf, stem and root parts of Jatropha curcas were collected and shade dried and extracted using ethanol in soxhlet assembely. Antifungal activity of leaf, stem and root extracts were tested against fungal pathogens of vegetable beans using disc diffusion method. The leaf extracts were very effective against fungal pathogens of vegetable beans in comparison to stem and root extracts. Preliminary phytochemical analysis of ethanol extract revealed the presence of phenols, tannins, flavonoids and reducing sugars in all plant parts viz. leaf, stem and root parts while alkaloids, glycosides and triterpenoids were present in leaf extracts. The observed inhibitory potential could be ascribed to the presence of secondary metabolites in the ethanol extracts. Thus the leaf, stem and root extracts in the ethanol can possibly be exploited in the management of fungal diseases of vegetable beans in an ecofriendly way.
The compound 2-(2-chlorophenylaminothiazole-5-oyl)-N-methyl-6-chlorobenzimidazole was characterized by IR spectral data. The optimized molecular geometry, bond lengths, bond angle and dihedral angle of the titled compound have been investigated by Density Functional Theory (DFT) method, using B3LYP method with 3-21G basis set available in Gaussian ’09 package. The results indicate that B3LYP method is able to provide satisfactory results for predicting vibrational frequencies and structural parameters. The IR spectra are obtained and assigned by vibrational analysis and found to be reliable compared with the literature observation. The Mulliken population analysis on atomic charges has been computed using DFT calculation. The lowering in the HOMO and LUMO energy gap explains the eventual charge transfer interactions that take place within the molecule.

Global population scale is daily increasing violently and this population needs enough food production and supply. For which, crop productivity needs to be improved by using strategies which should be free of bio-safety and ethical issues and crop harvest index is hampering by both the biotic and abiotic insults. These ailments can be surpassed by using novel miRNA based gene editing strategy and these miRNAs are the small non-coding RNAs over expressed under harsh environmental conditions, these miRNAs are nullifies the stress susceptible gene expression by translation inhibition/ RNA DICER formation. MiRNA research has been given an opportunity to develop the crop plants by using non-transgenesis approach. This review will be helpful in the development various crop plants tolerant to various abiotic stresses by using miRNA approach and also given an idea for the digging of miRNAs in maize after imposing various stresses like drought, salt and heat stress. The recent advancements in miRNA research has been given space to identification and characterization of miRNAs under different stress imposed plants and these miRNAs are most useful for the drought and heat stress prone vulnerable crops such as maize, rice and other cereals.
