Sir, In Gram-positive cocci, fluoroquinolone resistance is associated with mutational alterations in DNA gyrase and/or topoisomerase IV or with active efflux of the drugs. In Streptococcus pneumoniae, fluoroquinolone resistance is mainly due to substitutions in ParC (Ser-79→Phe or Tyr, Asp-83→Asn), ParE (Asp-435→Asn) or GyrA (Ser-81→Phe or Tyr, Glu-85→Lys or Gly).1,2 Therefore, detection of the...

Marker assisted selection (MAS) is a tool for breeding, screening, and genetic characterization of germplasm. Allelic variation of both high and low molecular weight glutenin subunits (HMW/LMW-GS) is associated with the rheological properties of wheat flour. In this study, we investigated glutenin pattern using SDS-PAGE and their PCR based on DNA markers in 60 advanced wheat lines and cultivars...

Aims: This study was aimed to determine whether ethanol exposure during early development altered neurogenesis in the brain of adult rats. Methods: Pregnant rats were given either ethanol-mixed or mannose-mixed (for control) rodent liquid diet ad libitum. Ethanol drinking continued during pregnancy and nursing. After weaning, the pups (ACo: pups from control mothers, AEo: pups from ethanol expo...

SNPs from nrDNA and cp trnC-trnD were analyzed from J. indica, J. recurva and Rushforth's juniper from Bhutan and compared with previous terpene and RAPD data. These data, taken together, show that Rushforth's juniper is allied, but distinct from J. indica and a new variety is named: J. indica var. rushforthiana R. P. Adams from Bhutan.

Spring durum wheat is an important raw material for producing diverse products such as couscous, bulgur, bread, and pasta. The quality of the dough significantly influenced by high-molecular-weight glutenins, allelic status which depends on region breeding program. In this study, a collection 69 cultivars promising lines were analyzed state Glu-A1 Glu-B1 using SDS-PAGE KASP PCR markers. Protein...

Low molecular weight glutenin subunits are important components of wheat storage proteins, which play an important role in determining end-use quality of common wheat. A newly established matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) procedure was used to analyze 478 landraces of bread wheat collected from the Yangtze-River region in China. Results ...
