โฆ Synopsis
Genetic relatedness of 20 Salmonella isolates comprising 16 serotypes was analysed by restriction endonuclease digestion of the total DNA with six endonucleases individually. The rDNA fingerprints generated by EcoRI were more polymorphic, each serotype showed a unique fingerprint sharing several core (monomorphic) bands with several polymorphic bands. Eight characteristic NciI rDNA fingerprints were found. Similar rDNA RFLP patterns were observed in strains of Salmonella from different serotypes.

RFLPs were used to study genome evolution and phylogeny in Brassica and related genera.

Preliminary analysis using nuclear RFLPs provided evidence that subspecies within Brassica rapa originated from two different centers. One center is in Europe, represented by turnip and turnip rape from which the oilseed sarson was derived. A second center is in South China containing a variety of C
