Gonad development in fish is generally assumed to be negatively influenced by interspecific hybridization, resulting in sterility or sub-sterility. However, this is not the case in sturgeons (Acipens...
Premise of the study : Elucidating the factors that determine the abundance and distribution of species remains a central goal of ecology. It is well recognized that genetic differences among indivi...
This Czech-American research collaboration is investigating interspecific hybridization among various fir species produced via control pollination. Its aim is the development of newly bred material fo...
The project is based on control pollination of different fir species in the sense of interspecific hybridization. The aim of this procedure is a new bred material for specific needs of forestry and Ch...
Variation of metric and qualitative characteristics of A. incana (L.) Moench. and A. glutinosa (L.) Gaertn. has been studied in 10 natural populations in West Siberia, Russia and the Czech Republic in...
Cultivated lentil L. culinaris was crossed to the wild species L. tomentosus ILWL90 and ILWL120. An ovule rescue technique was used to overcome interspecific incompatibility. Out of 296 hybrid ovules ...
Native chickens hold a significant share of the market in China. In response to the huge demand from the market, the productivity of Chinese native chickens needs to be improved. Cross breeding is an ...
The genus Diorhabda (Coleoptera: Chrysomelidae) was recently revised, using morphological characters, into five tamarisk-feeding species, four of which have been used in the tamarisk (Tamarix spp.) bi...
Telomeres are special structures at the ends of eukaryotic chromosomes. Vertebrate telomeres consist of tandem repeats of conserved TTAGGG sequence and associated proteins. Birds are interesting model...
The usefulness of scaly rhododendrons in hybridizing with Kurume azalea (cultivar group of Rhododendron × obtusum) cultivars was examined in order to expand the variations of the Kurume azalea group. ...
Low fertility and hatchability rate is a hindrance in chicken-quail hybridization. An investigation was undertaken to increase fertility and consequently hatchability of quail eggs inseminated with ch...
The expression of photosynthesis-related genes, rbcS (small subunit of ribulose 1,5-bisphosphate carboxylase/oxygenase) and cab (light-harvesting chlorophyll a/b-binding protein), in emerging rice lea...
Can Hot-Water Emasculation Be Applied to Artificial Hybridization of Indica-Type Cambodian Rice?
A new and simple boiling method for extracting chrysanthemum stunt viroid (CSVd) RnA is described. Fresh leaves of CSVd-infected chrysanthemum were homogenized in an equal volume of CTAB buffer then c...
Protoplasts were isolated from cell suspension culture of Kütdiken (Citrus limon (L.) Burm. f.) and from the leaves of Zagara Bianca lemon (Citrus limon (L.) Burm. f.) varieties, and fused by using 4...
