Banana micropropagation for obtaining free-virus plants frequently provokes somaclonal variation that could increase useful genetic variability in this asexually propagated crop. Both exploring the cycle of vitro culture which occurs and amount generated polymorphism, are necessary. In work, preliminary results during early cycles banana reported. Four randomly selected regenerated from fifth t...

Plants regenerated from tissue culture and their progenies are expected to be identical clones, but often display heritable molecular and phenotypic variation. We characterized DNA methylation patterns in callus, primary regenerants, and regenerant-derived progenies of maize using immunoprecipitation of methylated DNA (meDIP) to assess the genome-wide frequency, pattern, and heritability of DNA...

Abstract Induced mutations are important for genetic research and breeding. Mutations induced by physical or chemical mutagenesis usually heterozygous during the early generations. However, must be fixed prior to phenotyping field trials, which requires additional rounds of self-pollination. Microspore culture is an effective method produce double-haploid (DH) plants that homozygotes. In this s...

Dioscorea rotundata is a staple food crop for millions of people in the tropical and subtropical regions. In vitro germplasm conservation very useful tool yam improvement strategies but little known about genetic integrity stability in-vitro conserved plants. this study, 42 accessions from field populations were genotyped using 11 microsatellite markers 23 morphological descriptors to assess va...

Production of genetically and phenotypically stable plantlets is the main purpose in commercial strawberry tissue culture. In this study, different tissues of Fragaria ananassa cv. Camarosa including stipule, apical meristem, leaf and petiole were cultured in Murashige and Skoog (MS) medium supplemented withdifferent concentrations of N6-benzyladenine (BA) (0.5, 1, ...
