Bacillus thuringiensis subsp. israelensis Cyt1Aa synergizes Cry11Aa toxin by functioning as a membrane-bound receptor.
Evidence is provided that Cyt1Aa functions as a receptor of Cry11Aa, a highly effective pathogenic bacterium that produces a toxin and also its functional receptor, promoting toxin binding to the target membrane and causing toxicity.
Heterogeneity of Glutamine Synthetase Polypeptides in Phaseolus vulgaris L.
Glutamine synthetases from roots, nodules, and leaves of Phaseolus vulgaris L. have been purified to homogeneity and their polypeptide composition determined.The leaf enzyme is composed of six
Isolation and characterization of a Saccharomyces cerevisiae mutant with impaired glutamate synthase activity
Evidence is presented which suggests the possibility that S. cerevisiae has two GOGAT activities, designated GOG at A and GOGat B, which can be distinguished by their pH optima and by their regulation by glutamate.
A Rhizobium tropici DNA region carrying the amino‐terminal half of a nodD gene and a nod‐box‐like sequence confers host‐range extension
The narrow‐host‐range of Rhizobium leguminosarum biovars phaseoli and trifolii can be extended to Leucaena esculents and Phaseolus vulgaris plants, respectively, by the introduction of a DNA fragment 521 bp long.
Rhizobial Lipo-Oligosaccharide Signals: Their Biosynthesis and Their Role in the Plant
Results are presented which tempt us to believe that lipo-oligosaccharides, similar to those produced by rhizobia, are naturally occurring in the uninfected plant.
