Biography

Professor Priti Krishna has a strong background in diverse but related disciplines, such as microbiology (MSc), medical biochemistry (PhD), plant molecular biology (academic career at Western University, Canada) and agronomy (University of New England, Australia), and proven record of leadership in developing and executing pioneering research projects. She joined Western Sydney University in 2017 as the Foundation Chair in Sustainable Agriculture and has been actively leading campus-wide renewal of Agriculture. She held individual NSERC Discovery Grants throughout her academic career in Canada and was a particpant in large-sized collaborative projects funded by Networks of Centers of Excellence, Agriculture and Agri-Food Canada, and Ontario Research Fund. At Western Sydney University, she has been a key player in the development of the recently awarded Future Food Systems CRC proposal.  

Her research outputs with highest impact are: 

1) Instigating research and establishing the role of a relatively new plant hormone brassinosteroid in stress tolerance.

2) Instigating research and developing molecular tools for plant Hsp90 and its cochaperones, which were instrumental in proving the role of the Hsp90-chaperone system in plant disease resistance. 

3) Raising awareness of the health and commercial benefits of sea buckthorn, and aiding the development of sea buckthorn industry in Ontario through research.

She served as Senior Director and Eastern Regional Director on the Canadian Society of Plant Physiologists (CSPP) Executive between 2002 to 2009, and was the organiser of the scientific program of the Annual CSPP conference in 2000. She has been an active reviewer of research proposals under various research programs of funding agencies, including NSERC, NSF, DOE, CIHR, A-ISRF etc., as well as of manuscripts submitted to various journals, including the Plant Cell, TIPS, PNAS etc.

1) Brassinosteroids (BRs) are a relatively new class of plant hormones that offer a unique opportunity to simultaneously enhance plant growth and tolerance to a broad range of stresses. Work pioneered in P. Krishna’s laboratory has shown that 1) BR confers tolerance to a broad range of stresses 2) BR regulates growth and stress responses interactively to determine balanced outputs, and 3) BR-response genes control multiple traits, leading to simultaneous enhancements. Current research is focussed on BR effects on root system architecture under stress conditions and and correlation with nutrient uptake and gene expression.

2) The Hsp90-based chaperone machinery is implicated in numerous cellular processes, including protein folding, degradation and trafficking, signal transduction, and genomic silencing. Due to its interactions with signalling components, human Hsp90 has emerged as a drug target for control of cancer progression. P. Krishna's laboratory instigated research on plant Hsp90 and its cellular roles, established the presence of and partially characterized an Hsp90-based chaperone system in plants, and generated valuable molecular tools which were instrumental in identifying the essential role of Hsp90 in plant disease resistance. 

3) Sea buckthorn (Hippophae rhamnoides L.) is a hardy plant that is known for its medicinal and nutritional attributes in Asia and Europe. While its potential for the functional food and nutraceutical industry had been realized by European and Asian countries, there was little interest in this plant in Canada despite it being grown as a shelterbelt species. P. Krishna's laboratory provided the first comprehensive genome sequences for sea buckthorn, and a detailed phytochemical profiles of sea buckthorn fruits and leaves of cultivars growing in Canada. This work drew in support from the Ontario Ministry of Agriculture & Food, sea buckthorn breeders and growers, and generated considerable interest and support for the sea buckthorn industry in Ontario.

4) Current research focus is on projects within the Future Food Systems-CRC eg., 'Optimising blueberry fruit nutritional quality using controlled spectra and mild stress treatment via polytunnel innovation.'
