Project description:Boron is an essential micronutrient for plants and is taken up in the form of boric acid (BA). Despite this, a high BA concentration is toxic for the plants, inhibiting root growth and is thus a significant problem in semi-arid areas in the world. In this work, we report the molecular basis for the inhibition of root growth caused by boron. We used microarrays to detail the global gene expression underlying boron toxicity in roots.

Project description:Spatial distribution of soil bacterial communities around Ziziphus lotus vegetation clusters in semi-arid Moroccan ecosystems
Project description:The transcriptome signature of peripheral blood mononuclear cells (PBMCs) of Ladakhi cattle adapted to high altitude vis a vis Sahiwal cattle adapted to the arid/semi-arid region at mean sea level was established using bovine expression microarray chips. The transcriptome analysis of PBMCs from these cattle types living at two distinct altitudes, resulted in identification of several hundred differentially expressed genes, biological processes, molecular functions and pathways.

Project description:Boron is an essential micronutrient for plants and is taken up in the form of boric acid (BA). Despite this, a high BA concentration is toxic for the plants, inhibiting root growth and is thus a significant problem in semi-arid areas in the world. In this work, we report the molecular basis for the inhibition of root growth caused by boron. We used microarrays to detail the global gene expression underlying boron toxicity in roots. 5-day-old arabidopsis plants were transferred to medium with high boron concentration (½ MS medium supplemented with 5mM BA) and control conditions (½ MS medium). We determined that 5 mM BA is the minimum concentration that produces the maximum effect, stunting root growth by ~50% after 5 days as compared with control conditions. We analyzed the transcript profiles in roots by microarray analysis (Affymetrix ATH1 Genome Array). We compared the transcripts obtained at 12 hrs of BA treatment.
