Research Interest:
Plant Microbes Interactions, Characterization of Secondary Metabolites of Rhizobacteria
In an effort to minimize the use of chemicals in agriculture, my group is in pursuit of developing more efficacious bio-fertilizers and bio-pesticides.
The research plan involves the isolation of plant growth promoting rhizobacteria (PGPR) from roots, shoots and rhizosphere of plants belonging to diverse environmental backgrounds with divergent physiological attributes. We use microbiological and molecular biology tools and biochemical tests for the identification of bacterial isolates. These isolates are then screened for plant growth promoting abilities including nitrogen fixation, phosphate and zinc solubilizations, phytohormone productions, etc. The attained bacterial strains are tested for their effectiveness by inoculating them with a diverse range of plant species.The microflora attained is screened for its anti-pathogenic activity against bacterial and fungal pathogens for the development of bio-pesticides. The secondary metabolites are extracted, identified and characterized by using, TLC, HPLC, MS and NMR. Currently, we have a grant from HEC to work on bacteria which can be used as biocontrol (biopesticides) agents.

Research Interest: Molecular Biology of Plant Microbes Interactions, Osmo-Regulation and Bioenergy Production
Plants specifically crops are foremost in the initiation of the biotechnological boom as they cannot only be used to produce a diverse range of products but also generate ample amounts of food for the ever increasing population of Pakistan. My group is interested in elucidating the fundamental mechanisms and genetics targeted at improving plant productivity. These projects are aimed at building genetically engineered transgenic wheat varieties with enhanced bioavailability for iron and zinc and enriched fertilizer use efficiencies. We are also developing bio-fertilizers for boosting crop productivity and diagnostic strips for detection of Bt (Cry1ac and Cry2ab) genes in cotton. We are improving, upgrading and designing molecular biology based tools to detect food spoilage and are in the process of producing genetically modified biomass for biofuel production. We as a research group are adamant on discovering new and novel knowledge and technologies for the improvement of crops. Our long term vision in this regard is to contribute to alleviation of poverty and hunger, development of sustainable agricultural systems and the reduction of the negative impact that agriculture has on our environment. We believe that agricultural biotechnology can effectively suffice for these pressing needs and is the best tool to generate a positive influence on the grander scale.

Research Interest: Endocrinology and Metabolism, Genetic and Endocrine Aspects of Obesity in Children, Reproductive Dysfunction Associated with Familial Metabolic Diseases. Obesity has emerged as a major global health burden with a number of associated chronic diseases such as type 2 diabetes and cardiovascular disease, amongst others. During the last two decades, prevalence of obesity at an early age has markedly increased not only in the West but also in South Asian countries including Pakistan. Heritability studies indicate that genetic factors play a significant role in a predisposition to obesity leading to metabolic changes and altering the energy balance of the body. Our current research focuses on identifying known and novel genetic variants associated with early onset of severe obesity by screening key genes involved in the maintenance of body weight and energy balance. In addition, physiological changes in severely obese subjects are assessed by measuring circulating metabolites and hormones. It is expected that the present study will help in coupling genetic screening with metabolic profile, as a novel and more efficient diagnosis of severe obesity in the medical practice, leading to appropriate patient management.

Dr Aftab Bashir (HEC-approved supervisor)
Research Interest: Development of Transgenic Plants for Specific Traits including cotton fiber improvement, disease resistance, drought and salt tolerance and utilization of sweet proteins
My research areas mainly focus on the development of transgenic plants with improved nutritional quality and tolerance to abiotic stresses in wheat and improved quality of the cotton fiber traits. The key genes of interest include hormone homeostasis and water/ion transporter genes for wheat and cotton transformation. Regulation of these genes is crucial in plant vigor and fiber/fruit quality, prevention of premature apoptosis, ion homeostasis against abiotic stresses, cotton fiber elongation and regulation of isopentenyltransferase (IPT) which is vital to counteract drought and salt stress conditions. The modulation of hormone and ion homeostasis at the whole plant and specific tissue level to improve plant vitality and productivity is one of our goals. We are also interested in utilization of sweet proteins for improving the sweetness of fruits including citrus and Cucumis melo. At present the sweet protein genes including the Brazzien and Miraculin have been synthesized and the establishment of tissue culture system for Cucumis melo is underway. In addition, the transgene based identification of transgenic plants by developing the dipsticks against the expressed proteins is another area of focus. The technology for the development of dipsticks has been developed and tested against the Cry1Ac and Cry2ab (Bt) proteins. We are continuing our efforts for the commercial scale production of Bt testing dipsticks and also developing dipsticks for each of the genes that is used in our labs for development of transgenic plants.

Research Interest: Biology of Termites, Integrated Pest Management Strategies, Biological Control of Pests
Subterranean termites are one of the world’s most destructive, xylophagous pests of human structures and economically important plants. Nationwide costs for prevention, control, and repair attributable to subterranean termites is estimated to be in excess of $11 billion annually. Despite their economic impact, relatively little is known about these social insects.
Termite baiting systems are used as a pest management tool for the control of termites. These require information about their biology; specifically population ecology, optimum placement of bait-stations and discovery and consumption of active ingredients by termites for efficient pest control. Environmental concerns over the use of potent chemical termiticides have renewed interest in using pathogens for control of termites. The termite habitats are humid and of a relatively constant temperature. These are ideal for microbial growth, while crowded conditions and social interaction in termite nests encourage transmission of the pathogens.

Dr Natasha Anwar (HEC-approved supervisor)
Research Interest: Molecular Diagnostics of Infectious Diseases, Molecular Biology of Cancers
The aim of our research group is to translate information from basic science studies into applications for diagnostics medicine. As we have gained a better understanding of the molecular basis of these diseases we can use the information to improve diagnosis and management. We are currently working in the lab to develop and optimize assays for the detection of Dengue Fever Virus (DFV) – detection and genotyping of DFV RNA from human serum samples and adult mosquitoes. We are also assaying Chronic Myeloid Leukaemia (CML) – screening for the T315I mutation in patients treated with on tyrosine kinase inhibitors to distinguish and quantify wild type or T315I mutant ABL transcripts that render patient resistant to treatment. High specificity as few as 5 copies of the T315I mutant transcript or 0.025% (2.5×10(-4)) T315I mutant transcripts could be detected by this method. Additionally we are interested in developing improved assays for Hepatitis C Virus (HCV) – identification of rs12979860 polymorphisms in patients with HCV genotype 1 and 3 infections. A single nucleotide polymorphism (SNP) rs12979860, upstream of the IL28b gene (interferon lambda 3) on chromosome 19 (C – T polymorphism) is a major predictor of natural viral clearance and response to antiviral therapy.  Screening for SNP and also measuring IFN-gamma release from dendritic cells isolated and cultured from patients with genotype 3 infections will be correlated with viral clearance. Lastly we are studying and assaying Mycobacterium tuberculosis (MTb) – development and commercialization of a blood based tuberculosis diagnostic in collaboration with UC Davis, USA through a US-PAK technology transfer grant UC Davis. We are also working with School of Biological Sciences and Ghulab Devi Chest Hospital for recruiting TB patients for the study.
