Creating Novel Wx Alleles with Fine-tuned Amylose Levels and Improved Grain Quality in Rice by Promoter Editing using CRISPR/Cas9 System
CRISPR/Cas9 System Fine-tuned Amylose Grain Quality Rice
2023/8/9
In rice, the Waxy (Wx) gene encoding GBSSI (granule-bound starch synthase I) controls amylose synthesis in the endosperm and is the primary factor influencing grain eating and cooking quality (ECQ). T...
Evaluation of the effectiveness of introducing new alleles into the gene pool of a rare dog breed: Polish Hound as the example
dog pedigree analysis mtDNA
2015/6/23
The results indicated
the very limited breeding success of such dogs in relation to their contributions to the gene pool and to the
number of their descendants used in breeding. Dogs of unknown or...
TaqMan allelic discrimination assay for A1 and A2 alleles of the bovine CSN2 gene
allelic discrimination CSN2 alleles A1 and A2 cattle
2015/6/8
Alleles A1 and A2 of the Bos taurus CSN2 gene are the most frequent in a number of dairy cattle breeds. In this study, a new allelic discrimination assay using TaqMan fluorogenic probes was developed ...
Associations of HLA alleles with specific language impairment
Specific language impairment (SLI) HLA Neurodevelopmental disorders Genetic association
2015/5/5
Human leukocyte antigen (HLA) loci have been implicated in several neurodevelopmental disorders in which language is affected. However, to date, no studies have investigated the possible involvement o...
Allele-specific PCR detection of sweet cherry self-incompatibility alleles S3, S4 and S9 using consensus and allele-specific primers in the Czech Republic
Prunus avium S-alleles allele-specific primers consensus primers
2015/3/24
Prunus avium species of the Rosaceae family exhibit gametophytic self-incompatibility. Determination of the self-incompatibility genotype of individuals is essential for genetic studies and the develo...
Resistance of winter wheat varieties registered in the Czech Republic to Fusarium head blight in relation to the presence of specific Rht Alleles
deoxynivalenol content disease severity traits dwarfing allele Rht-D1b Fusarium culmorum head blight plant height variety resistance winter wheat
2014/3/10
Resistance of 31 winter wheat varieties (bred in 6 European countries) to Fusarium head blight (FHB) was evaluated in field trials lasting for three years (2007, 2008, 2009) after artificial inoculati...
Development of CAPS marker for identifi cation of rym4 and rym5 alleles conferring resistance to the Barley Yellow Mosaic Virus complex in barley
barley marker-assisted breeding mosaic virus complex resistance rym allele identification
2014/3/10
In barley, soil-borne viruses of the barley mosaic virus complex (BaYMV, BaMMV, BaYMV-2) are of high importance due to their increased spread, yield losses, and the fact that protection with chemicals...
Difference in Combination between Glu-B1 and Glu-D1 Alleles in Bread-Making Quality Using Near-Isogenic Lines
wheat high-molecular-weight glutenin near-isogenic line
2009/6/17
The difference of combination between Glu-B1 and Glu-D1 alleles in bread-making quality was investigated using the near-isogenic lines (NILs) of Glu-1 alleles. We found that composition of the HMWG su...
Polymorphism of κ -Casein in Italian Goat Breeds:A New ACRS-PCR Designed DNA Test for Discrimination of A and B Alleles
ACRS-PCR genetic polymorphism goat κ-casein
2009/3/20
The objective of this study was to develop a DNA test for rapid characterisation of goat κ-casein (κ-CN) A and B variants and to study this polymorphism in Italian goat breeds. Genetic polymorphism of...
Identification of Multiple Alleles at the Wx Locus and Development of Single Segment Substitution Lines for the Alleles in Rice
rice waxy gene single segment substitution line allelic variation molecular marker-assisted sele
2009/1/7
The microsatellite markers 484/485 and 484/W2R were used to identify the multiple alleles at the Wx locus in rice germplasm. Fifteen alleles were identified in 278 accessions by using microsatellite c...
