The receptors of the dopamine neurotransmitter belong to two unrelated classes named D1 and D2. For the D1 receptor class, only two subtypes are found in mammals, the D1A and D1B, receptors, whereas additional subtypes, named D1C, D1D, and D1X, have been found in other vertebrate species. Here, we analyzed molecular phylogeny, gene synteny, and gene expression pattern of the D1 receptor subtype...

A total of 205 wheat cultivars from the Yellow and Huai valley of China were used to identify allelic variations of vernalization and photoperiod response genes, as well as the copy number variations (CNVs) of Ppd-B1 and Vrn-A1 genes. A novel Vrn-D1 allele with 174-bp insertion in the promoter region of the recessive allele vrn-D1 was discovered in three Chinese wheat cultivars and designated a...

Endopeptidase allele Ep-D1c and DNA marker-assisted selection have been used for the incorporation of Lr19 + Lr24 leaf rust resistance genes combination into adapted commercial winter wheat cultivars. The first step was the transfer of the gene Lr19 from the donor cultivar Agrus into acceptor cultivars Simona and Lívia. The progenies possessing the null allele Ep-D1c linked to the gene Lr19 hav...

Most modern wheat cultivars contain major dwarfing genes, but their effects on root growth are unclear. Near-isogenic lines (NILs) containing Rht-B1b, Rht-D1b, Rht-B1c, Rht8c, Rht-D1c, and Rht12 were used to characterize the effects of semi-dwarfing and dwarfing alleles on root growth of 'Mercia' and 'Maris Widgeon' wheat cultivars. Wheat seedlings were grown in gel chambers, soil-filled column...

Grain hardness is one of the most important quality characteristics of wheat (Triticum aestivum L.). It is a significant property of wheat grains and relates to milling quality and end product quality. Grain hardness is caused by the presence of puroindoline genes (Pina and Pinb). A collection of 25 genotypes of wheat with unusual grain colour (blue aleurone, purple and white pericarp, yellow e...

Ancient and modern 183 varieties of winter 23 spring types development bread wheat (Triticum aestivum L.) selected Ukrainian state institutions private companies are characterized by alleles Ppd-D1, Ppd-B1, Ppd-A1 genes. Allele-specific molecular markers, proposed in the scientific literature, were used to identify carriers Ppd-D1a, Ppd-D1b, Ppd-D1c, Ppd-D1d, Ppd-B1a, Ppd-B1c, Ppd-A1b alleles. ...

We tested the virulence in mice of Toxoplasma gondii RH strain tachyzoites containing various copies of the chloramphenicol acetyl transferase-herpes simplex virus thymidine kinase fusion sequence (CAT-HSTK). Tachyzoite isolates containing >/=five copies of the fusion sequence were not lethal to female CD-1 outbred or BALB/c inbred mice, at doses up to 10(6) parasites, while the parental RH str...

grain hardness is one of the most important quality characteristics of cultivated bread wheat (triticum aestivum l.) that has main effect on milling yield, particle size, and water absorption of wheat flour. kernel hardness is mainly controlled by ha locus on the short arm of chromosome 5d in bread wheat. in this study, we have employed a multifaceted approach to investigate aspects of grain ha...
