Genetic Variability of Acetolactate Synthase (ALS) Sequence in Centaurea cyanus Plants Resistant and Susceptible to Tribenuron-Methyl

نویسندگان

چکیده

Centaurea cyanus, belonging to the Asteraceae family, is an arable weed species encountered mainly in fields with cereals, sugar beet, and maize. The high genetic variability of C. cyanus has been recently reported; however, little known about its sequence context herbicide resistance. resistance was found against acetolactate synthase (ALS) inhibitors, but no ALS information concerning mechanism published yet. aim this study determine sequences for biotypes susceptible resistant tribenuron-methyl order identify mutations that may be associated emergence. DNA isolation from plants followed by PCR amplification sequencing. As a result, different lengths products were obtained. Moreover, both nucleotide amino acid analysis revealed within one plant as well between same biotype. In few plants, four changes identified comparison those ones. However, these preliminary studies require further investigation toward confirming significance development. This provides contributing research on target-site mechanism.

ilvB-encoded acetolactate synthase is resistant to the herbicide sulfometuron methyl.

The herbicide sulfometuron methyl is a potent inhibitor of the branched-chain amino acid biosynthetic enzyme acetolactate synthase (ALS) isolated from bacteria, fungi, and plants. However, it did not prevent growth of wild-type Salmonella typhimurium LT2 or Escherichia coli K-12. These species each contain two acetolactate synthase isozymes. Growth of S. typhimurium and E. coli mutants lacking ...

Protein trans-splicing to produce herbicide-resistant acetolactate synthase.

Protein splicing in trans has been demonstrated both in vivo and in vitro by biochemical and immunological analyses, but in vivo production of a functional protein by trans-splicing has not been reported previously. In this study, we used the DnaE intein from Synechocystis sp. strain PCC6803, which presumably reconstitutes functional DnaE protein by trans-splicing in vivo, to produce functional...

The Staphylococcus aureus α-Acetolactate Synthase ALS Confers Resistance to Nitrosative Stress

Staphylococcus aureus is a worldwide pathogen that colonizes the human nasal cavity and is a major cause of respiratory and cutaneous infections. In the nasal cavity, S. aureus thrives with high concentrations of nitric oxide (NO) produced by the innate immune effectors and has available for growth slow-metabolizing free hexoses, such as galactose. Here, we have used deep sequencing transcripto...
