The AROM locus of A. nidulans, which governs five consecutive steps in pre-chorismate aromatic amino acid biosynthesis, has been cloned in a bacteriophage vector. The nucleotide sequence of the locus reveals a single, open reading-frame of 4,812 base-pairs, apparently without introns. An internal segment of the A. nidulans AROM sequence has extensive homology with the E. coli aroA gene that enc...

A suspected glyphosate-resistant goosegrass [Eleusine indica (L.) Gaertn.] population, found in Washington County, Mississippi, was studied to determine the level of resistance and whether the resistance was due to a point mutation, as was previously identified in a Malaysian population. Whole plant dose response assays indicated a twoto four-fold increase in resistance to glyphosate. Leaf disc...

Abstract Menaquinone-7 (MK-7) is a kind of vitamin K2 playing an important role in the treatment and prevention cardiovascular disease, osteoporosis arterial calcification. The purpose this study to establish adaptive evolution strategy based on chemical modulator improve MK-7 biosynthesis Bacillus natto . inhibitor 5-enolpyruvylshikimate-3-phosphate synthase (EPSP synthase), glyphosate, was ch...
