متن کاملDoubled Haploidy Research for Saskatchewan Crops
Doubled haploidy methodology is commonly used in many agronomically important crops to speed the development of new cultivars. There are a number of advantages in using haploidy technology in both practical application (varietal development, mutagenesis, transformation) and basic research (genomics, biochemical, and physiological studies). Haploid plants are commonly produced using one of four ...
متن کاملThe evolution of haploidy and diploidy
Tremendous diversity exists among organisms with respect to their ploidy level, defined as the number of sets of homologous chromosomes per cell. As differences in ploidy represent a potentially major genomic change affecting the evolution of a species, it might be thought that ploidy evolution would be well understood. In fact, our knowledge is fragmentary, and there are several open questions...
متن کاملEditorial: Doubled Haploidy in Model and Recalcitrant Species
Doubled haploid (DH) technology is a powerful tool in plant breeding to reduce the time and costs needed to produce pure lines, the cornerstone of hybrid seed production. This biotechnological alternative to classic methods allows for a reduction of the typical 7–8 inbreeding generations needed to fix a hybrid genotype to only one in vitro generation. It is therefore much faster and cheaper, be...
متن کاملEvidence for haploidy in metacyclic forms of Trypanosoma brucei.
The parasitic flagellate Trypanosoma brucei undergoes a series of morphologic and metabolic changes during its passage in the digestive organs of its insect vector, a Glossina or tsetse fly. This morphogenesis ends by the differentiation, in the salivary gland of the fly, of the metacyclic form, which will be transmitted in the bloodstream of the mammalian host. On the basis of DNA microfluorom...
