The aim of present study was to evaluate the linkage disequilibrium (LD) of p.R72P, PIN3 Ins16bp, p.P47S, p.R213R and r.13494g[a polymorphism of TP53 and their haplotypes association with oesophageal cancer risk in patients from Punjab, northwest India. A total of 466 samples, including 233 oesophageal cancer patients and 233 healthy individuals were analysed. Data analysis revealed the gender specific association. In female group, arginine-proline (RP) genotype (P = 0.08) and P allele (P = 0.07) of p.R72P polymorphism was marginally associated with increased risk of oesophageal cancer. A1A2 genotype (P = 0.06) and A2 allele (P = 0.07) of PIN3 Ins16bp polymorphism was marginally associated with decreased risk of oesophageal cancer in male group. A1A2-GA genotype combination (P = 0.04) of PIN3 and r.13494g[a polymorphisms was significantly associated with decreased risk of oesophageal cancer in male group. learn more In female group, PP-GA genotype combination (P = 0.02) of p.R72P and r.13494g[a polymorphisms and RP-A1A1-GG genotype combination (P = 0.04) of p.R72P, PIN3 and r.13494g[a polymorphisms was significantly associated with increased risk of oesophageal cancer. We observed moderate LD between two intronic polymorphisms PIN3 Ins16bp and r.13494g[a (D´ = 0.90; r2 = 0.68). Haplotype analysis revealed that none of the haplotype combination was associated with oesophageal cancer risk when both the genders were considered. Stratification on the basis of gender showed that P-A2-P-A-A haplotype of p.R72P, PIN3 Ins16bp, p.P47S, p.R213R and r.13494g[a polymorphisms was marginally associated with reduced oesophageal cancer risk in male group (P = 0.08). Replication of these findings in independent cohorts may be insightful for the role of TP53 in oesophageal cancer pathogenesis.Psoriasis-2 (PSORS2) is caused by the heterozygous mutation of the caspase recruitment domain 14 (CARD14) gene on chromosome 17q25. To evaluate the contribution of CARD14 variants in psoriasis of the Chinese Han population, we performed deep sequencing of the CARD14 gene in 372 Chinese Han patients with psoriasis. The exonic nucleotide variants were confirmed by Sanger sequencing in the affected individuals and 1114 controls. In 27 patients with psoriasis, we identified 15 variations, including three novel variants c.381C[G (p.Cys127Trp), c.712A[G (p.Met238Val) and c.2260_2261delinsGG (p.Gln754Gly). These findings could enrich and update the Human Gene Mutation Database of CARD14 variants for psoriasis.In heterozygote state, we interogressed three chromosomal segments of Drosophila koepferae in D. buzzatii. The effect of each introgression was evaluated in the fertility of the segmental males, quantifying the amount of offspring produced. Through specific crosses method, we generated Drosophila segmental isolines carrying specific chromosomal introgression segments. The introgressions were monitored cytogenetically by the method of molecular markers of chromosomal asynapsis. The statistical analysis showed that none of the three segments evaluated, introgressed individually or in pairs, as well as cis or trans, do not produce sterility in the segmental males, as determined by the normal productions of offspring. Additional introgressions using other larger segments show that when the introgressions reach a minimum size of 31.15%, they produce sterility. It is concluded that the hybrid sterility genes present in the three segments evaluated did not act in strong epistasis, but show a pattern of gradual additive behaviour by requiring a minimum threshold size to produce sterility. Finally, we also isolated the smallest introgressing segment that has been reported for these species (2.19%), and for the first time we have managed to place it in homozygous state (data not shown), so we are now in the process of evaluating the ability to these segments in homozygous state.The present study was undertaken to delineate genotype-environment interactions and stability status of 16 genotypes of ashwagandha (Withania somnifera (L.) Dunal) in context to the 12 characters, namely plant height, number of primary branches, number of secondary branches, days to flowering, days to maturity, number of berries, number of seeds/berry, root length, root diameter, root branches, dry root yield and total alkaloid content (%). Experiment was carried out in a randomized complete block design with three replicationsover three different locations (S. K. Nagar, Jagudan and Bhiloda) in north Gujarat for three years (2016-17, 2017-18 and 2018-19). Pooled analysis of variance revealed that the mean squares due to genotypes and genotype 9 environment interaction along with linear and nonlinear components were highly significant (P less then 0.01) for most of the traits under study. Stability parameters for component traits through Eberhart and Russell model showed that genotypes that can be used directly in breeding programme are SKA-4 for early flowering, SKA-21 for early maturity and SKA-1, SKA-4, SKA-6 and SKA-17 for shorter plant height. Further, SKA-21 could be used for improving number of primary branches per plant, SKA-11 and SKA-17 for number of secondary branches per plant, SKA-19 for number of berries per plant, SKA-6, SKA-21, SKA-27 and AWS-1 for root branches and SKA-17 for root length as these genotypes were found to be moststable across the environments for mentioned traits. The result revealed that some reliable predictions about genotype 9 environment interaction and its unpredictable components were involved significantly in determining the stability of genotypes. Hence, the present investigation can be exploited for the identification of more productive genotypes in specific environments, leading to significant increase in root productivity of ashwagandha.Eukaryotic and prokaryotic cell genomes exhibit multiple microsatellites. In this study, we characterized microsatellites in genomes and genes of Nanorana parkeri and Xenopus laevis. This characterization was used for gene ontology (GO) analysis of coding sequences (CDS). Compared to the genome of N. parkeri, the genome of X. laevis is larger and contains more number of microsatellites, but the diversity of both species are similar. Trinucleotide repeats in the genome of N. parkeri and dinucleotide and tetranucleotide repeats inthe genome of X. laevis were the most diverse. In both the species, diversity of microsatellites was highest in intergenic regions, followed by intron and exon regions, and lowest in coding regions. Microsatellites in CDS are thus subject to higher selective pressure. Many microsatellites are concentrated upstream and downstream of genes in both species, suggesting suppression of repeats in the middle of protein-CDS. Repeats are enriched in regions near gene termini purely due to the biophysical constraints of protein structure.
