Application of subspecies-specific marker system identified from O. sativa to O. glaberrima accessions and O. sativa × O. glaberrima F1 interspecific progenies

Interspecific hybrids (F1's) between Asian rice (Oryza sativa 2n=24 AA) and African rice (Oryza glaberrima 2n=24 AA) are almost completely sterile. This hybrid sterility barrier is mainly caused by an arrest of pollen development at the microspore stage. Intersubspecific F1 hybrid sterility is mainly caused by cryptic chromosomal aberrations and allelic interaction between indica and japonica. To identify O....

Identification of Ralstonia solanacearum using conserved genomic regions

The aim of the present study is to develop a scheme for identification of Ralstonia solanacearum with high specificity based on conserved genomic regions. Short Tandem Repeats (STRs) in R. solanacearum genome were searched using Tandem Repeat Finder software. A total of 189 and 74 STRs were found in chromosomal and megaplasmid DNA respectively. Sequence homology of these STRs analyzed using BLAST showed that out of...
