To decipher the molecular and biochemical basis of seed vigor, longevity and seedling establishment

We aim to understand how orthodox seeds maintain vigor and viability for a prolonged period of time (longevity) in quiescent stage and how quiescent seeds restart their metabolism to prepare seedling establishment. Using this knowledge,   how seed vigor, seed storage life and seedling performance can be improved in crop plants is our ultimate goal.
The following specific topics represent some of the current interests of our laboratory.
Inositol and Raffinose Family Oligosaccharide (RFO) Metabolism in chickpea: In perspective of seed vigor, longevity and stress tolerance

Inositol has been shown to be an essential component for plant growth and development; therefore plants maintain inositol pool at basal level throughout their life cycle. However, not all but few stress tolerant plants like ice plant, chickpea were shown to elevate their inositol level in response to environmental stresses, possibly to meet additional demand of inositol which might be required for their adaptation to stresses.

This inositol is produced through the conversion of glucose 6- phosphate to myo inositol 1- phosphate by the enzyme L- myo inositol 1- phosphate synthase (MIPS) and subsequently myo inositol 1 - phosphatase (IMP) produces free inositol.  Free inositol then can be channelized in several pathways including RFO biosynthesis and is implicated in various physiological processes.

Our interest is to study the role and regulation of inositol and RFO metabolism in chickpea particularly in seed and stress biology through molecular genetics and biochemical approach.
Understanding the role and regulation Ubiquitin /26S Proteasome Pathway in seed germination

Plant growth, development and environmental adaptations are mostly controlled by the selective removal of short lived regulatory proteins. One major proteolytic pathway to remove these regulatory proteins   in eukaryotes is the ubiquitin (Ub)/ 26S proteasome pathway. In plants, this pathway plays a crucial role in the control of many different cellular processes like embryogenesis, hormonal regulations, flowering, senescence, photo morphogenesis, circadian rhythm, pathogen resistance and environmental adaptation. The genome of Arabidopsis encodes more than 1400 (>5% of the proteome) pathway components which is more than twice that of yeast, Drosophila, mice and human. Why plants have placed a particular emphasis on this proteolytic system is poorly understood. How E3s are regulated and what are the substrates of the Ub/26S proteasome pathway in plants are big queries for the   plant biology research.

Our laboratory is attempting to elucidate the role of this proteolytic pathway in seed biology. What specific function does this pathway play in seed biology and seedling establishment and how this pathway be constructively manipulated?
Uncovering the role of regulation of PROTEIN L- ISOASPARTYL METHYLTRANSFERASE (PIMT) in seed and stress biology.

Proteins and peptides are the most significant macromolecules which carry out the essential functions of the cell. They are susceptible to a variety of spontaneous modifications as they age and also in stressful conditions. Among such protein modifications, conversion of L-aspartyl or asparaginyl residues to abnormal isoaspartyl (isoAsp) residues in proteins is quite prevalent among organisms. However, this damage could be repaired by the protein repairing enzyme PROTEIN L-ISOASPARTYL METHYLTRANSFERASE (PIMT). PIMT is a widely distributed protein repairing enzyme which catalyzes the conversion of abnormal L-isoaspartyl residues in spontaneously damaged proteins to normal aspartyl residues. This enzyme is encoded by two divergent genes (PIMT1 & PIMT2) in plants in contrast to most of the bacterial or animal systems, where this enzyme is encoded by a single gene. The role of PIMT is not well elucidated in higher plants. Based on the occurrence of high PIMT activity in quiescent and germinating seeds, the role of PIMT in seed vigor and longevity has been suggested.

Our interest is to uncover the role and regulation of PIMT isoforms in plant system and is also directed towards the identification of PIMT substrates/age damaged proteins particularly in seed.
