Priti has expertise in the general area of molecular biology/biochemistry/genomics. She has led a research group for the last 20 years in the area of plant stress biology, focusing on
| 1) | the functions and mode of action of Hsp90 in plants. The Hsp90-based chaperone machinery is implicated in numerous cellular processes, including protein folding, degradation and trafficking, signal transduction, and genomic silencing. The Krishna lab has been working to identify the client proteins and co-chaperones of plant Hsp90 and study their functional interrelationships. |
| 2) | the molecular mechanism by which brassinosteroids (BRs), a relatively new group of plant hormones, confer tolerance in plants to a wide range of environmental stressors. The Krishna lab has been working to identify BR-responsive genes and pathways that converge on producing broad-spectrum stress tolerance and increase in yield potential. |
| 3) | the genomics of sea buckthorn, a hardy, fruit-producing plant known historically for its medicinal and nutraceutical properties. The most recognised product of sea buckthorn is its fruit oil, composed of seed oil that is rich in essential fatty acids, linoleic and a-linolenic acids, and pulp oil that contains high levels of monounsaturated palmitoleic acid. |
