Abstract
Several cDNA libraries were constructed using mRNA isolated from roots, panicles, cell suspensions and leaves of non-stressed Oryza sativa indica (IR64) and japonica (Azucena) plants, from wounded leaves, and from leaves of both cultivars inoculated with Rice Yellow Mottle Virus (RYMV). A total of 5549 cleaned expressed sequence tags (ESTs) were generated from these libraries. They were classified into functional categories on the basis of homology, and analyzed for redundancy within each library. The expression profiles represented by each library revealed great differences between indica and japonica backgrounds. EST frequencies during the early stages of RYMV infection indicated that changes in the expression of genes involved in energy metabolism and photosynthesis are differentially accentuated in susceptible and partially resistant cultivars. Mapping of these ESTs revealed that several co-localize with previously described resistance gene analogs and QTLs (quantitative trait loci).Entities:
