Genetic Analysis and Molecular Mapping of Red Pericarp Gene in Oryza longistaminata

To effectively explore and exploit the favorable alleles in Oryza longistaminata for rice improvement, especially in breeding for perennial rice or for fixing rice heterosis with perenniality, an F2 population containing 227 individuals derived from an interspecific cross RD23 / O.

Construction of cDNA Library and EST Sequences Analysis of Oryza longisatminata Rhizomatous

To explore the extraction of total RNA from Oryza longisatminata, the author attempt modified SDS method, CTAB method and TRIzol method, comparing the extraction effect of these methods, by electrophoresis in general agarose gel and spectrophotometer readings.
