Journal of Applied Toxicology, EarlyView.ABSTRACT Children, as a particularly vulnerable group, are more susceptible to these mutagens due to their developing immune systems, higher physiological vulnerability, and increased exposure through behaviors like outdoor play and hand‐to‐mouth activities. This review aims to investigate the relationship between these environmental exposures, genetic

Ethidium bromide: a nucleic acid stain for tissue section.
, 1981 The phenanthridinium dye, ethidium bromide (EB), selectively intercalates into double-stranded regions of nucleic acids with a large and specific increase in fluorescence.

Mutagenic Improvement of Xylanase Production from Xylanolytic Bacteria and its Phylogenetic Analysis
Microbiology Indonesia, 2013 This study was conducted to obtain xylanolytic mutants that have higher xylanase activity than their wildtype counterparts. A mutant with the best xylanolytic activity was selected and identified based on its 16S rRNA sequence.

Saussurea × media (Asteraceae), a new natural hybrid between S. parviflora and S. controversa
Nordic Journal of Botany, EarlyView.Saussurea × media Yusupovsky and E.Pjak (Asteraceae), a new nothospecies from the Altai‐Sayan Mountains, is described and illustrated. In this study, we sequenced the internal transcribed spacer of nuclear ribosomal DNA and the chloroplast intergenic spacers rsp16‐trnQ and ycf4‐cemA to verify the hypothesis of hybridization between Saussurea parviflora

Pest Management Science, EarlyView.Malathion resistance in Spanish field populations of Ceratitis capitata is associated with a point mutation (R allele) and a heterogeneous duplication (RS haplotype) of the Ccace2 gene. The R allele imposes a higher fitness cost than the RS haplotype under laboratory and field conditions. An evolutionary model supports the stability of the RS haplotype
