Plant Tissue Culture, Molecular Biology and Genetic Engineering

  1. Visited Institute of Plant Genetics, Polish Academy of Sciences (IPG PAS), Poznan, Poland under the India-Poland Inter-Governmental Bilateral research project supported by the Department of Science and Technology (DST), Government of India and Polish National Agency for Academic Exchange (NAWA), Poland during 1st - 21st June 2023.
  2. Visited Queensland University of Technology (QUT), Brisbane, Australia in the third series of Stewardship training on the aspect of pro-vitamin A (PVA) and iron content analysis in transgenic banana fruit samples under the BIRAC funded banana biofortification collaborative research project during 12th – 17th October 2015.
  3. Visited Queensland University of Technology (QUT), Brisbane, Australia in the second series of Stewardship training on the aspect of (i) safety, (ii) compliance, (III) containment and confinement, (iv) product identity and (v) quality and sustainability under the BIRAC funded banana biofortification collaborative research project during 24th – 27th August 2014.
  4. Visited QUT, Brisbane, Australia in the first Stewardship training on capacity enhancement in banana transformation and regeneration methodology under the BIRAC funded banana biofortification collaborative research project during 10th and 14th December 2012.
  1. In the international collaboration, we are working towards the enhancement of pro-vitamin A (PVA) content in banana. Multiple gene constructs from Queensland University of Technology (QUT), Australia and developed by us those which are capable of enhancing PVA were transferred in cultivated varieties of Indian Banana. Containment trial for the genetically engineered banana with high PVA content is being performed by following biosafety guidelines. Promising banana lines are being evaluated for bioavailability, nutritional and multilocation agronomical trials with other national institutes/universities.
  2. Gene editing for target banana genes has been initiated for enhancing the synthesis/stability of carotenoids, iron and ascorbic acid in banana.
  3. Transgenic wheat lines with low phytic acid (PA) were generated.
  4. Marker-free / transgene-free transformation / genome editing procedures for banana, wheat and pea are being explored and developed.
  5. Two major contributions were derived from my doctoral research. The first one was the expression of cholera toxin B subunit fusion with rabies glycoprotein in peanut/groundnut seed which also demonstrated immunoprotection in mice. It was a step-forward research in the direction to develop plant-seed-based edible vaccine against cholera and rabies (received DR. YSR BioAsia Innovation Young Scientist Award-2010). The second outcome was the expression of insect resistance Cry1EC protein in leaves of peanut which showed complete protection against economical important polyphagous foliage insect tobacco cutworm (Spodoptera litura) (received 97th Indian Science Congress Association (ISCA) Young Scientist Award-2010).

Metabolic engineering of staple crops (banana and wheat) for nutritional enrichment: Banana and wheat are important staple crops that significantly contribute towards food security in many developing countries where vitamin A and iron deficiencies are the major problems. Biofortification of these crops for beta-carotene and iron enhancement is being considered by us as a promising, cost-effective and sustainable solution. For this, we are utilizing modern biotechnological approaches like transgenic, cisgenic, depletion of anti-nutrient (by RNAi) and genome editing (by CRISPR-CAS). We are generating new knowledge and implementing the available resources of genomics, bioinformatics, transcriptomics and metabolomics for precise metabolic engineering of the relevant biosynthetic pathways in these two crops. Further, the biofortified crops would be analyzed for nutritional and agronomical performance with the appropriate collaborative efforts in due course of time.
