Induction of genetic variability in oat

open access: yesCrop Breeding and Applied Biotechnology, 2007
Genetic variability in plants can be maximized through techniques of induction to make selection of genotypes with improved adaptation to cultivation conditions possible. For oat, these techniques are important for a sustainable development through plant

Investigation of the effect of space flight factors on chromosomes in seeds [PDF]

open access: yes
Frequency of mutations in postflight air-dry Crepis capillaris seeds, kept for five days aboard an artificial satellite was 36.0 + or - 1.9%, vs. 19.01 + or - 1.2% for seeds in a similar ground experiment.

Graph kernels based on tree patterns for molecules

open access: yes, 2006
Motivated by chemical applications, we revisit and extend a family of positive definite kernels for graphs based on the detection of common subtrees, initially proposed by Ramon et al. (2003).

Development of new vegetable soybean (Glycine max L. Merill) mutants with high protein and less fibre content [PDF]

open access: yesElectronic Journal of Plant Breeding, 2010
Soybean (Glycine max L. Merill) tops the world production of oil seeds. Mutation breeding is the most useful and vitaltechnology for soybean. Selection of effective and efficient mutagens are very essential to recover high frequency ofdesirable mutants ...

Flagellar motility is mutagenic

open access: yesProceedings of the National Academy of Sciences
Flagella are highly complex rotary molecular machines that enable bacteria to not only migrate to optimal environments but also to promote range expansion, competitiveness, virulence, and antibiotic survival. Flagellar motility is an energy-demanding process, where the sum of its production (biosynthesis) and operation (rotation ...

Mutation breeding: an underutilized strategy for improving finger millet productivity and nutritional quality

open access: yesFrontiers in Sustainable Food Systems
Finger millet is a climate-resilient cereal notable for its exceptional nutritional properties, yet it remains underutilized mainly because of its narrow genetic diversity and slow breeding progress.

The comparative mutagenic effectiveness and efficiency of electron beam, gamma rays, ethyl methane sulphonate and sodium azide to induce novel genetic variation in grain amaranth (A. hypochondriacus L.)

open access: yesHeliyon
Induced mutagenesis serves as an effective method for generating variation in underutilized crops such as amaranth, with limited breeding advancements. The mutagenic effectiveness and efficiency of a mutagen are critical factors influencing the success ...

Microbial nucleic acids employed in diagnostics, sequencing and phylogenetics are subject to detrimental inhibitors and mutagens [PDF]

open access: yes, 2009
Sequencing the genomes of microbial species has increased tremendously. Nucleic acids (NA) are used also for diagnostic and phylogenetic analyses of microbes. It is essential that protocols ensure representative NA.
