Pseudomonas entomophila is an entomopathogenic bacterium that is lethal to Drosophila melanogaster within 1-2 days of ingestion of high doses. Flies orally infected with P. entomophila rapidly succumb despite the induction of both local and systemic immune responses. Recent studies suggest that its virulence relies on its ability to cause irreversible damages to the intestinal epithelium, in co...

Current study aimed to search for safe and effective natural products to control the potato soft-rot disease, Erwinia carotovora subsp. carotovora. Antibacterial efficiency of edible mushroom extracts (MEs) and garlic essential oil (EO) were compared with two bactericides; streptrol and oxolinic acid as well as two fungicides; mancopper and copper oxychloride. Bioassay experiments were conducte...

Specific growth rate constants were used to evaluate the effects of selected herbicides on Erwinia carotovora, Pseudomonas fluorescens, and Bacillus sp. Comparison of growth rate constants permitted the identification of either stimulatory or inhibitory effects of these substances. E. carotovora was inhibited by 6,7-dihydrodipyrido(1,2-a:2'-c)pyrazinediium (diquat) and 4-hydroxy-3,5-diiodobenzo...

EARLY RESPONSIVE TO DEHYDRATION 15 (ERD15) is rapidly induced in response to various abiotic and biotic stress stimuli in Arabidopsis (Arabidopsis thaliana). Modulation of ERD15 levels by overexpression or RNAi silencing altered the responsiveness of the transgenic plants to the phytohormone abscisic acid (ABA). Overexpression of ERD15 reduced the ABA sensitivity of Arabidopsis manifested in de...

The screening of large arrays of drug-like small-molecules was traditionally a time consuming and resource intensive task. New methodology developed within our laboratories provides an attractive low cost, 3D microarray-assisted screening platform that could be used to rapidly assay thousands of compounds. As a proof-of-principle the platform was exploited to screen a number of quorum sensing a...

A total of 91 isolates of probable antagonistic bacteria of potato soft rot bacterium Erwinia carotovora subsp. carotovora (Ecc) were extracted from rhizospheres and endophytes of various crop plants, different soil varieties, and atmospheres in the potato farming areas of Bangladesh. Antibacterial activity of the isolated probable antagonistic bacteria was tested in vitro against the previousl...
