We have cloned DNA methyltransferases (MTases) from various strains of Neisseria gonorrhoeae. Each of these clones represents a single specificity, indicating that the multiple gonococcal MTase specificities are encoded by monospecific MTases. The DNAs of five strains (FA5100, F62, MS11, Pgh3-2, and WR302) were digested with NheI, SpeI, or NheI plus SpeI and subjected to pulsed-field gel electr...

ABSTRACT The barley cv. Bolivia carries two leaf rust (Puccinia hordei) resistance genes, Rph2 and Rph6, and is the only known source of the latter gene. A resistant line (Bolivia-Rph6) carrying Rph6 only was obtained in the F(4) generation of a cross between cv. Bolivia and the susceptible cv. Bowman via progeny testing with differential isolates of the leaf rust pathogen. Genetic analyses and...
