Abstract

SUMMARY: Cosmid gene libraries of the obligate methylotrophs and AS1 were generated by ligating 3A partial digests of chromosomal DNA into the broad-host-range cosmid vector pLA2917. Genetic linkage groups were identified for each organism by complementation following mobilization of the recombinant cosmids to a wide range of and auxotrophs. The linkage data thus obtained confirmed and extended those previously established by prime plasmid complementation, and the two methylotrophs showed very similar arrangements for four of the gene clusters studied. However, comparison of DNA sequences which complemented the same auxotrophic markers failed to demonstrate restriction fragment identity or substantial DNA-DNA homology between the two methylotrophs.
