BACKGROUND DNA methylation is sensitive and responsive to stressful environmental conditions. Nonetheless, the extent to which condition-induced somatic methylation modifications can impose transgenerational effects remains to be fully understood. Even less is known about the biological relevance of the induced epigenetic changes for potentially altered well-being of the organismal progenies re...

Phytophthora ramorum has three populations belonging to the same species: the two North American populations (NA1 and NA2) and the European population (EU1). All three populations are genetically distinct lineages, as revealed by different molecular marker systems. P. ramorum is also heterothallic, with two opposite mating types, A1 and A2. All NA1 and NA2 isolates are of the A2 mating type. Al...

The research aimed to produce new genotypes by hybridization. It was conducted in the Ornamental Plants Research Center of Mahallat from 2016 to 2018. Four varieties of gladiolus including Amsterdam, White Prosperity, Advance Red and Rose Supreme were chosen for hybridization. The progenies were evaluated in a randomized complete block design with three replications. The highest heritability in...

Electrophoretic analysis of two or three linked enzyme loci in progenies of homozygous females from cage and natural populations demonstrates frequent concurrent multiple paternity in both cases.

The iron concentration (FeC) and zinc (ZnC) in common bean grain are quantitative traits, appropriate breeding techniques required to achieve genetic gain. aim of this study was obtain a recurrent selection population black increase the FeC ZnC select superior progenies for formation next cycle lines. base formed by crosses among ten parents. A total 351 were obtained, and, after two generation...

Abstract To avoid the surrounding pollination, seed orchards of Finnish plus trees have been established in Ukraine, i.e., far from their natural distribution. However, it is unknown whether pollination site affects frost hardiness (FH) progenies and thus use forest regeneration Finland. Using whole-plant freezing tests, we examined FH tree orchard Finland with three lots seeds each orchard, tw...

degradation of natural habitats and decreasing of genetic diversity of populus caspica led to vast reduction of its regeneration and growth potential in north of iran. hence, the growth potential of mass-produced seedlings was compared with their parents. for this purpose, the ramets of three selected seedlings from 17 parent trees belonging to north of iran, along with ramets of their parent t...

Cotton leaf curl virus disease (CLCuD) is an important constraint to cotton production. The resistance of G. arboreum to this devastating disease is well documented. In the present investigation, we explored the possibility of transferring genes for resistance to CLCuD from G. arboreum (2n = 26) cv 15-Mollisoni into G. hirsutum (2n = 52) cv CRSM-38 through conventional breeding. We investigated...
