A Lactobacillus helveticus-Specific DNA Probe Detects Restriction Fragment Length Polymorphisms in This Species.
A cloned 2-kb EcoRI fragment (fragment f) from a 34-kb plasmid of Lactobacillus helveticus CNRZ 1094 was shown by dot blot to specifically hybridize to total DNAs of 75 L. helveticus strains. No hybridization was found with L. acidophilus, L. crispatus, L. delbrueckii subsp. bulgaricus, L. delbrueckii subsp. lactis, L. gasseri, or L. intestinalis strains. When Southern blots of EcoRI digests of...
متن کاملMan Using Restriction Fragment Length Polymorphisms
We describe a new basis for the construction of a genetic linkage map of the human genome. The basic principle of the mapping scheme is to develop, by recombinant DNA techniques, random single-copy DNA probes capable of detecting DNA sequence polymorphisms, when hybridized to restriction digests of an individual's DNA. Each of these probes will define a locus. Loci can be expanded or contracted...
متن کاملNeisseria gonorrhoeae by restriction fragment length polymorphisms
Objective-To characterise Neisseria gonorrhoeae isolates by restriction fragment length polymorphisms (RFLPs) in ribosomal RNA genes. Design-Generation of RFLP patterns by HincII restriction of rRNA genes followed by hybridisation with a nonradioactive labelled broad spectrum 16 + 23S rRNA gene probe. This typing method was developed and compared with MAb based serotyping. Specimens-Forty three...
متن کاملInheritance of restriction fragment length polymorphisms in Agaricus brunnescens.
The cultivated mushroom, Agaricus brunnescens, is secondarily homothallic; most basidia produce only two basidiospores, each of which receives two of the four post meiotic nuclei. The segregation of restriction fragment length polymorphisms (RFLPs) detected by four plasmid probes carrying single-copy nuclear DNA of Agaricus was followed in seven parental strains including commercial, wild-colle...
متن کاملMapping flagellar genes in Chlamydomonas using restriction fragment length polymorphisms.
To correlate cloned nuclear DNA sequences with previously characterized mutations in Chlamydomonas and, to gain insight into the organization of its nuclear genome, we have begun to map molecular markers using restriction fragment length polymorphisms (RFLPs). A Chlamydomonas reinhardtii strain (CC-29) containing phenotypic markers on nine of the 19 linkage groups was crossed to the interfertil...
