Research Summary:

Research in my lab is focused on gene discovery and utilization including the development of molecular markers to accelerate breeding efforts for improved stress resistance using marker assisted breeding (MAS).  A major emphasis is to elucidate co-evoultion of the rice Pi-ta resistance gene with the corresponding avirulence gene AVR-Pita1 in Magnaporthe oryzae, and identification and mapping sheath blight resistant QTLs.  Specific aims are: (1) develop robust pathogenicity assays of rice blast and sheath blight to facilitate the isolation of differentially expressed genes, and (2) determine defense signaling networks by DNA microarray and/or serial analysis of gene expression and/or sequence analysis of differentially expressed genes from subtracted DNA libraries after rice is challenged either with sheath blight or rice blast pathogens, and (3) identification of critical genes involved in host-pathogen interactions using RNAseq and mutmap with next gen sequencing, (4) identify and verify genes that are induced or suppressed upon pathogen infection on the transcript level by RT-PCR and real time PCR. Induced plant genes in resistant and susceptible rice germplasm will be analyzed to facilitate molecular marker development for breeding for improved stress resistance using MAS.

· Develop a perfect DNA marker for an effective blast resistance gene.  In collaboration with EPAGRI, Brazil (http://www.epagri.sc.gov.br/?page_id=2099)

· Develop novel methods to improve blast resistance in US breeding programs.  Project supported by USDA-NIFA (http://vivo.usda.gov/display/NIFA-0231543-PROJ

· Fine map a major sheath blight resistant quantitative trait loci (QTL)

· Develop new methods for quantifying minor gene differences controlling resistance to rice sheath blight disease

· Determine genome sequences of two field isolates of rice sheath blight pathogen (R. solani).  Project supported by NSF and State of Arkansas  (http://www.plantpoweredproduction.com)

· Develop a controlled inoculation for rice false smut disease for germplasm screening

· Understand evolutionary basis of weedy red rice for crop protection and weed management.  Project supported by NSF (https://www.bio.umass.edu/weedy-rice

· Develop effective screening and molecular markers for identifying genetic resistance to rice bacterial panicle blight.  Project supported by Arkansas Rice Research and Promotion Board (http://www.arkrice.org)
