Chitinases are known to play an important role in many host-pathogen interactions. To reveal the defense associated role of chitinases in sugarcane during interaction with Colletotrichum falcatum causing red rot, detailed studies were conducted on the expression of chitinases in sugarcane cultivars varying in disease resistance, their characterization and(More)
Red rot is a serious disease of sugarcane caused by the fungus Colletotrichum falcatum imposing a considerable economic loss annually in all sugarcane-producing countries. In this study, we analyzed the early resistance response of sugarcane to red rot fungus by comparing the differences between control and inoculated stalk tissues. Differential display(More)
Detailed studies were taken up on host pathogen interaction between sugarcane and Colletotrichum falcatum causing red rot at the transcription level with a set of sugarcane varieties varying in disease resistance. A set of gene specific primers were designed to detect transcripts of resistance gene analogues (RGA’s), defense-related genes, transcription(More)
An effort has been made to isolate individual catechin compounds from green tea leaves in their pure form by electrophoresis. In the present study total polyphenol extraction was carried out initially and estimated through spectrophotometric and HPLC methods. Extracted polyphenol was separated on 0.7% agarose gel and visualized at 360 nm. Fragmented(More)
Using aerosol optical depth (AOD at 550 nm) from the moderate-resolution imaging spectroradiometer, surface winds, outgoing long-wave radiation from National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis, and rainfall from Tropical Rainfall Measuring Mission data sets, we report a dipolelike variability in the(More)
The objective of the present study was to investigate the utilization of pupal waste and silkworm litter separately as production media for the mass cultivation of the potential biopesticide, Bacillus thuringiensis (Bt). Bt is the most successful commercial biopesticide accounting for 90% of all biopesticides sold all over the world. Biochemical analysis of(More)
First ever 3-day aircraft observations of vertical profiles of Black Carbon (BC) were obtained during the Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX) conducted on 30(th) August, 4(th) and 6(th) September 2009 over Guwahati (26° 11'N, 91° 44'E), the largest metropolitan city in the Brahmaputra River Valley (BRV) region.
