Title
Molecular analysis of point mutations in a barley genome exposed to MNU and gamma rays
Marzena Kurowska; Anna Labocha-Pawłowska; Dominika Gnizda; et al. Mutation research. Fundamental and molecular mechanisms of mutagenesis 2012. doi:10.1016/j.mrfmmm.2012.08.008
Other claims from this paper (11)
- Observation MNU induced an average mutation density of 1/504kb in the barley genome by TILLING
- Observation Only one nucleotide change was found in the barley genome at the highest gamma-ray dose
- Intervention effect MNU was a more efficient mutagen than gamma rays in inducing point mutations in barley
- Observation Transitions made up 63.6% of MNU-induced nucleotide changes in barley
- Observation G>A and C>T substitutions occurred in a similar number among MNU-induced changes in barley
- Mechanism The similar share of G>A and C>T transitions indicates no strand bias in the repair of O(6)-methylguanine lesions in barley
- Observation Purines formed 81% of nucleotides observed at the -1 site next to the O(6)-methylguanine lesion in barley
- Observation A strong specificity of the nucleotide surrounding the O(6)-meG lesion at the -1 position was observed in barley
- Intervention effect MNU-treated barley showed about three times higher AFLP polymorphism than the gamma-irradiated population
- Observation Some AFLP bands in barley contained up to 8 different amplicons
- Observation The sequence types in polymorphic AFLP bands reflected the organisation of the barley genome
