The aim of the study was to development rice microspores in anther culture vitro , structure androclinic callus identify cyto-embryological features formation morphogenic structures culture, obtain doubled haploids ( Oryza sativa L .) and accelerate valuable breeding material with desired properties. Within framework this study, results a cyto-histological haploid androgenesis were obtained, wh...

Doubled haploid (DH) technology is an efficient strategy for producing completely homozygous lines breeding programs. Mutations in the MATRILINEAL (MTL) phospholipase trigger intraspecific induction cereals. Although vivo system based on OsMTL-edited plants has been established rice (Oryza sativa), DH still limited by other factors, such as identification, which one of essential steps required ...

Strains of baker's yeast conventionally used by the baking industry in Japan were tested for the ability to sporulate and produce viable haploid spores. Three isolates which possessed the properties of baker's yeasts were obtained from single spores. Each strain was a haploid, and one of these strains, YOY34, was characterized. YOY34 fermented maltose and sucrose, but did not utilize galactose,...

Sexual eukaryotic organisms are characterized by haploid and diploid nuclear phases. In many organisms, growth and development occur in both haploid and diploid phases, and the relative length of these phases exhibits considerable diversity. A number of hypotheses have been put forward to explain the maintenance of this diversity of life cycles and the advantage of being haploid versus that of ...
