RNA-Seq is increasingly being used for gene expression profiling. In this approach, next-generation sequencing (NGS) platforms are used for sequencing. Due to highly parallel nature, millions of reads are generated in a short time and at low cost. Therefore analysis of the data is a major challenge and development of statistical and computational methods is(More)
BACKGROUND MicroRNAs are a class of small non-coding RNAs that regulate mRNA expression at the post - transcriptional level and thereby many fundamental biological processes. A number of methods, such as multiplex polymerase chain reaction, microarrays have been developed for profiling levels of known miRNAs. These methods lack the ability to identify novel(More)
An improved protocol for extraction of prokaryotic mRNA from soil samples was developed by modifying the extraction procedure to obtain higher yields of mRNA and to reduce co-extraction of humic acids. The modified protocol was found to be more robust and efficient compared to the original protocol by Griffiths et al. (2000) without compromising with the(More)
To compare the target and non-target effects of two chemical-pesticides (chlorpyrifos and endosulfan) with that of a bio-pesticide (azadirachtin), Vigna radiata (mung bean) was grown in a randomized pot experiment with recommended and higher application rates of pesticides. Colony counts enumerating specific microbial populations, viz. fungi, Pseudomonas,(More)
Intensive agriculture has resulted in an indiscriminate use of pesticides, which demands in-depth analysis of their impact on indigenous rhizospheric microbial community structure and function. Hence, the objective of the present work was to study the impact of two chemical pesticides (chlorpyrifos and cypermethrin) and one biological pesticide(More)
With increasing application of pesticides in agriculture, their non-target effects on soil microbial communities are critical to soil health maintenance. The present study aimed to evaluate the effects of chemical pesticides (chlorpyrifos and cypermethrin) and a biological pesticide (azadirachtin) on growth parameters and the rhizospheric bacterial(More)
Bioinoculants are commonly used for enhancing crop productivity but little information is available on their effect on key microbial communities such as those involved in the cycling of nitrogen, a major plant nutrient. Here we developed a formulation combining different bioinoculants (Bacillus megaterium, Pseudomonas fluorescens and Trichoderma harzianum)(More)
Inoculation of leguminous seeds with bioinoculants has been practiced in agriculture for decades to ameliorate grain yield by enhanced growth parameters and soil fertility. However, effective enhancement of plant growth parameters results not only from the direct effects these bioinoculants impose on them but also from their non-target effects. The ability(More)
To study the effects of two chemical pesticides (chlorpyrifos and endosulfan), and a bio-pesticide (azadirachtin) on bacterial diversity in rhizospheric soil, a randomized pot experiment was conducted on mung bean (Vigna radiata) with recommended and higher doses of pesticides. Denaturing gradient gel electrophoresis was used to analyze such effects on both(More)
