Genetic recombination in Micromonospora.
Biochemical mutants were obtained from Micromonospora chalcea, M. purpurea, and M. echinospora by using ultraviolet radiation or nitrosoguanidine. Crosses carried out between complementary nutritional mutants of the same species showed positive genetic interaction. Data are reported which indicate that the interaction between the crossed strains is due to genetic recombination. No evidence for ...
متن کاملGenetic recombination in plants.
Meiotic recombination generates novel allelic arrays on chromosomes. Recent experiments have revealed an extraordinarily nonrandom distribution of recombination breakpoints along the lengths of plant chromosomes; for example, recombination breakpoints often resolve within genic sequences, and thereby generate novel alleles. The mechanism by which recombination breakpoints are determined is an a...
متن کاملGenetic recombination in mycobacteria.
Evidence for genetic recombination between Mycobacterium smegmatis strain Rabinowitchi (Rab) and strain Jucho or PM5 is presented. Backcrosses of recombinants by either parental strain indicated four different types of mating behavior, suggesting that the mycobacterial compatibilities are controlled by at least two different factors. No sex factor that transfers at a high frequency or that is s...
متن کاملGene transfer in Caulobacter crescentus: polarized inheritance of genetic markers.
Recombination frequencies were determined for 15 independently isolated auxotrophs of C. crescentus crossed pairwise in all possible combinations. The results indicate that the mutants may be grouped into at least two types: "fertile" strains, which recombine with all other mutants at frequencies ranging from less than 10-6 to 3 times 10-2, and "nonfertile" strains which recombine with fertile ...
