Archaeal stress response:

The study of archaea, the third domain of life can provide interesting insights into the evolutionary history of different cellular pieces of machinery and mechanisms across all life forms. One such mechanism of our concern is that of protein translocation across biological membranes in archaea. Our present focus is on the structural and functional analyses of molecules that are central to the archaeal secretion process under different limiting conditions. Since archaea can sustain such extreme limiting conditions, withstanding different kinds of stresses, we also aim to get a thorough idea about the effect of different types of stressors on archaeal cells at the transcriptomic and proteomic levels. We want to study the fate of stress-related proteins under conditions of stress, which includes identification, characterization, and analysis of the mode of regulation of stress-related proteins and their targets. Therefore, the current research in our lab is concerned with understanding the effect of heat stress on archaea in regard to different molecular chaperones. In addition, our recent venture is to study the role of toxin-antitoxin systems in stress adaptation in archaea.

Stress adaptation of environmental microbes:

A changing environment creates conditions that can be stressful for microorganisms. To cope with environmental stress, microbes have a variety of evolutionary adaptations and physiological acclimatization mechanisms. Such adaption and acclimatization strategies allow them to survive and remain metabolically active in the face of environmental stress. However, not all microorganisms are equipped with the necessary arsenals to adapt to the changing environment, and therefore a shift in microbial community composition is often documented under stress conditions. It is believed to be mainly due to a change in ecosystem-level carbon, energy, and nutrient flows that drive alteration in microbial dynamics.

In contrast to conventional strategies of understanding specific organismal responses to environmental stress, our approach aims at developing a more reliable connection between microbial and ecosystem ecology. In our laboratory, we study the diversity, distribution, and function of microorganisms (archaeal and bacteria) in the natural environment. We study microbial structure and function in two unique ecosystems, i.e., the Sundarban mangrove ecosystem and the tea plantation ecosystem of Darjeeling. We adopt genomic and proteomic approaches to find out novel metabolic pathways involved in either heavy metal resistance, antimicrobial resistance, biocatalysis, and novel antimicrobial biosynthesis, etc., in the resident microorganisms. Moreover, we extend our interest in a study of the host (plant)-associated microbiome in these environments. Plants are intimately associated with vast numbers of microorganisms in the rhizosphere. The rhizosphere microbiome is not static, and the microbial community structure in the rhizosphere micro-niche can change in response to stresses and environmental stimuli. Recent studies support that the changes in the rhizosphere microbiome are not merely passive responses of plants but rather, as a consequence of millions of years coevolution, plants likely actively seek cooperation with microbes to fight stresses. We study the rhizosphere microbiome of mangrove plants and tea plants with particular emphasis on plant-growth-promoting rhizobacteria (PGPR).
