Plant (a)biotic stress
Tissue culture and dihaploid breeding
Research in my group uses a holistic approach, integrating molecular biology and functional genomics tools, with an overarching goal of improving agronomic traits of interest in field crops. Inexorable climate change would only exacerbate the biotic and abiotic stressors that negatively impact the growth and productivity of field crops. Members within primary, secondary and tertiary gene pool of crops vary with their ability to adapt to these stresses through physiological and biochemical adjustments. Strategies to develop climate-resilient designer crops depend on our depth of knowledge of plant’s responses to the stressors at tissue, cellular and molecular levels. Our research program involves basic molecular biology investigations in rice and Arabidopsis models to understand and identify the interplay of molecular genetic networks that regulate plant's tolerance/resistance under abiotic stresses, such as drought and salt. The knowledge generated from the basic research program is being translated to devise genetic tools that would complement conventional breeding efforts towards developing crop varieties with improved stress tolerance.
Sugarcane, in addition to its importance as a sugar crop, is regarded as an important second generation bioenergy grass (popularly known as energy cane). Marker-assisted breeding (MAB) can speed up conventional efforts to develop improved sugarcane varieties for the Louisiana sugar industry. Identification of stable molecular markers linked to a particular trait of interest, for example sucrose content, and biotic and abiotic stress resistance, is the key to a successful MAB. Our research aims to identify specific genes/gene-networks within the genomic regions that govern desirable traits towards development of allele-specific functional markers by exploiting the natural variations in traits that exist within the primary gene pool. We have deployed molecular markers to understand the genetic structure of Louisiana sugarcane gene pool – this information is currently being used in selection of parents for the crossing program to make sure maximum diversity is maintained to increase genetic gain. Our research focus is (1) to identify clones with high sucrose content using genomic selection – this will increase the accuracy of predicting performance based on genomic breeding values of new breeding lines; and (2) to develop and deploy markers for resistance to brown rust, leaf scald, and other imminent stressors, such as cold stress through a combination of gene expression and genome/association mapping strategies.
Similar experimental approaches are being used for development of DNA-based markers associated with various agronomic traits for their implementation in breeding of improved varieties of other commodity crops, such as wheat, sweetpotato and cotton.
