Improving cotton fibre quality is a major breeding goal for Upland cotton in China.To investigate the genetic mechanisms of fibre quality, a diverse panel of 403 Upland cotton accessions was grown, and the fibre quality traits were measured in six different environments. Genotyping was performed with genomewide simple sequence repeats. A total of 201 markers were polymorphic and generated 394 allele loci, and 403 accessions were arranged into two subgroups using Structure software. Of the marker loci, 18.94% showed significant linkage disequilibrium (P < 0...

Hereditary retinal diseases, known as retinal degenerations or dystrophies, are a large group of inherited eye disorders resulting in irreversible visual loss and blindness. They develop due to mutations in one or more genes that lead to the death of the retinal photoreceptor cells. Till date, mutations in over 200 genes are known to be associated with all different forms of retinal disorders. The enormous genetic heterogeneity of this group of diseases has posedmany challenges in understanding the mechanisms of disease and in developing suitable therapies...

We describe a case of a six-year-old girl who presents multiple dysmorphic features characteristic of Down's syndrome. She has a significant general developmental delay, with a score that correspond to 32 months of developmental age. This delay is especially in language, with a very scant vocabulary. She communicates with some hand sign words or pointing, although her auditory responses in hearing test were normal. Two previous karyotype studies showed 47, XXX, +21 anomalies. This double trisomy is a rare condition described in isolated cases in the literature and none of these refers to the developmental aspects of these children (Balwan et al...

The safflower (Carthamus tinctorius L.) is an oil seed crop from which the flowers is used as medicine and food colorants. The present investigation was undertaken to explore gene effects for safflower's pigments in flower including carthamin and carthamidin. Six generation including P1 , P2 , F1 , F2 , BC1 and BC2 that derived from two different crosses (Mex. 2-138 (P2 ) × Wht-Esf (P1 ) and C111 (P2 ) × Wht-Esf (P1 ) were used for generation of mean analysis. The joint scaling test showed that additive [a], additive × additive [aa], and additive × dominance [ad] effects were significant for genetic control of carthamin and carthamidin in both crosses...

Eucalyptus is an important industrial species with tolerance to drought and salt stress. Genetic improvement activities including quantitative trait loci (QTL) mapping for pulping and adventitious rooting traits are in progress, but no information is available on the genomic regions on adaptive traits such as stomatal characteristics. In this study, an interspecific cross between Eucalyptus tereticornis and E. grandis was generated for the development of genetic map and QTL identification for stomatal traits...

The transcription factor forkhead box N1 (Foxn1) plays an important role in the development and function of thymic epithelial cells (TECs) in vertebrates. However, the transcriptional regulation of Foxn1 is still unknown. A series of dual luciferase report vectors were constructed and their relative activities were also detected. The 5'-untranslated regions contains two cis-acting elements, Sp1 and GATA-1, as well as trans-acting elements between positions -332 to -438. Nevertheless, the relative activities of Foxn1 promoter were significantly increased in PK15 cells only when the Sp1 was overexpressed, suggesting that the Sp1 was the most important sequence for Foxn1 transcription activation in the pig...

We describe a newborn female with a de novo duplication of chromosomes 2q31.2 and 2q37.3, and a de novo monosomy 9p24.3. The clinical findings of this patient include congenital heart defects, dysmorphic facial features, hypotonia, feeding difficulties and microcephaly. Ultrasonographic prenatal findings were negative for foetal malformations. Only a mild pyelectasis was reported. This is the first report of molecular cytogenetic characterization of a partial trisomy 2q31.2-37.3 with monosomy 9p24.3.

The Indian Genetic Disease Database (IGDD) and Online Mendelian Inheritance in Man (OMIM) survey human populations that have different climate histories. Comparison of the two shows an outstanding difference in the relative frequency of recessive disease genes. Several of the diseases mediated at least in part by recessive gene mutations in India are not so mediated in the Western populations covered by OMIM, or are so mediated to a lesser extent. This we attribute to climate history, where population fall leading to inbreeding in the last ice age appears to have reduced the frequency of recessive disease genes in the Western world...

Testosterone is themain plasma androgen produced and secreted by male testis. To be bioactive, it binds to sex hormonebinding globulin (SHBG), i.e. the major transporter protein of sex steroids in the blood of mammals and other vertebrate species.Firstly, this study aimed to determine the levels of testosterone in different-age groups of buffalo bulls (Bubalus bubalis) in Egypt, and secondly to screen the genetic polymorphisms in their SHBG gene and to investigatewhether these polymorphisms are associated with the level of the circulating serum testosterone...

Maize is a valuable source of food and feed worldwide. Maize endosperm protein is, however nutritionally poor due to the reduced levels of two essential amino acids, lysine and tryptophan. In this study, recessive opaque2 (o2) allele that confers enhanced endosperm lysine and tryptophan, was introgressed using marker-assisted backcross breeding into three normal inbred lines (HKI323, HKI1105 and HKI1128). These are the parental lines of three popular medium-maturing single cross hybrids (HM4, HM8 and HM9) in India...

Van der Woude syndrome (VWS) shows an autosomal dominant pattern of inheritance with two known candidate genes, IRF6 and GRHL3. In this study, by employing genome-wide linkage analyses on two VWS affected families, we report the cosegregation of an intronic rare variant in NOL4 in one family, and a haplotype consisting of three variants in the noncoding region of IRF6 (introns 1, 8 and 3'UTR) in the other family. Using mouse, as well as human embryos as a model, we demonstrate the expression of NOL4 in the lip and palate primordia during their development...

The analysis of quantitative trait loci (QTLs) aims at mapping and estimating the positions and effects of the genes that may affect the quantitative trait, and evaluating the relationship between the gene variation and the phenotype. In existing studies, most methods mainly focus on the association/linkage between multiple gene loci and one trait, in which some useful joint information of multiple traits may be ignored. In this paper, we proposed a method of simultaneously estimating all QTL parameters in the framework of multiple-trait multiple-interval mapping...

Tassel architecture is an important trait in maize breeding and hybrid seed production. In this study, we investigated total tassel length (TTL) and tassel branch number (TBN) in 266 F2:3 families across six environments and in 301 recombinant inbred lines (RILs) across three environments, where all the plants were derived from a cross between 08-641 and Ye478. We compared the genetic architecture of the two traits across two generations through combined analysis. In total, 27 quantitative trait loci (QTLs) (15 in F2:3 ; 16 in RIL), two QTL × environment interactions (both in F2:3 ), 11 pairs of epistatic interactions (seven in F2:3 ; four in RIL) and four stable QTLs in both the F2:3 and RILs were detected...

Some subjects are repeatedly exposed to human immunodeficiency virus (HIV), yet they remain uninfected. This suggests the existence of host-resistance mechanisms. The current study synthesizes the evidence regarding the association between interleukin (IL) gene polymorphisms and HIV susceptibility. Medline, Scopus and the Web of Science databases were systematically searched, and a meta-analysis of case-control studies was conducted. Univariate and bivariate methods were used. The literature search identified 42 eligible studies involving 15,727 subjects...
