The explanation for heterosis phenomenon is based on ideas: (i) every trait of an organism depends on many genes. (ii) Inbreeding depression and heterosis are related to individual genetic diversity. To assess individual genetic diversity of an organism, I suggest the term number of genetic properties. Assessing the changes of individual genetic diversity caused by self-pollination and cross-pollination reveals that self-pollinating plants of natural cross-pollinating leads to the decrease in individual genetic diversity of offspring and crossing between pure lines of genetic difference leads to the increase in individual genetic diversity of hybrids...

Mayr (1942) defined sibling species as sympatric forms which are morphologically very similar or indistinguishable, but which possess specific biological characteristics and are reproductively isolated. Another term, cryptic species has also been used for such species. However, this concept changed later. Sibling species are as similar as twins. This category does not necessarily include phylogenetic siblings as members of a superspecies. Since the term sibling species was defined by Mayr, a large number of cases of sibling species pairs/groups have been reported and thus they are widespread in the animal kingdom...

Transposable elements usually comprise the most abundant nongenic fraction of eukaryotic genomes. Because of their capacity to selfreplicate and to induce a wide range of mutations, transposable elements have long been considered as 'parasitic' or 'selfish'. Today, we recognize that the findings about genomic changes affected by transposable elements have considerably altered our view of the ways in which genomes evolve and work. Numerous studies have provided evidences that mobile elements have the potential to act as agents of evolution by increasing, rearranging and diversifying the genetic repertoire of their hosts...

Despite of promising improvements in treatment of gastric cancer, the mortality rate of this malignancy remains high. Chronic infection by Helicobacter pylori, interfering with intracellular signalling pathways, is the main risk factor for gastric cancer. Some evidence suggests that microRNAs (miRNA), the small noncoding RNA molecules, can play role as oncogenes or tumour suppressors in the cells. MiR-222 is one of the remarkable miRNAs undergoing upregulation in gastric cancer. However, the association between miR-222 upregulation and H...

Alcohol-induced osteonecrosis of femoral head (ONFH) is one of the most important pathogenesis of nontraumatic ONFH. However, its pathogenesis mechanism is still unknown. Osteoprotegerin (OPG) has been implicated in multiple functions including blocking osteoclast maturation, controlling vascular calcifications, promoting tumour growth and metastasis. This study is focussed on OPG gene polymorphisms associated with alcohol-induced ONFH. A total of 509 participants (209 patients and 300 normal individuals) were recruited, and we selected 13 single-nucleotide polymorphisms (SNPs) to evaluate the association between genetic susceptibility variants and alcohol-induced ONFH by using the χ(2) test and genetic model analysis...

The soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is a plant-parasitic nematode that feeds on the roots of soybean and most economically devastating pathogen of soybean (Glycine max (L.) Merr.) worldwide. Host plant resistance is the most effective control method. To understand SCN resistance in different environments, two recombinant-inbred lines (RILs) populations NJ(RN)P7 (217 F2:8:11 lines) and JN(RN)P7 (248 F2:7:9 lines) were developed from the cross of the cultivars Peking x 7605 in Nanjing and Jinan, respectively, and examined in this study...

Epigenetic regulatory posttranslational histone modification marks not only function individually but also capable to act in combination as a unique pattern. A total of 16 plant species belonging to 11 genera of eight families (five dicots and three monocots) including land plants, epiphytes (orchids) and the holokinetic taxa (Drosera spp.) were analysed for chromosomal distribution of dual modified antiphospho (Ser10)-acetyl (K14)-histone H3 (H3S10phK14ac) to understand the combinatorial chromatin dynamics during mitotic cell division in plants...

This study aimed to identify vernalization responsive genes in the winter wheat cultivar Jing841 by comparing the transcriptome data with that of a spring wheat cultivar Liaochun10. For each cultivar, seedlings before and after the vernalization treatment were sequenced by Solexa/Illumina sequencing. Genes differentially expressed after and before vernalization were identified as differentially expressed genes (DEGs) using false discovery rate (FDR) ≤ 0.001 and |log2 (fold change)|>1 as cutoffs. The Jing841-specific DEGs were screened and subjected to functional annotation using gene ontology (GO) database...

Grain yield is a complex character representing a multiplicative end product of many yield attributes. However, understanding the genetics and inheritance that underlies yield and its component characters pose a prerequisite to attain the actual yield potential of any crop species. The knowledge pertaining to gene actions and interactions is likely to direct and strengthen the crop breeding programmes. With this objective, the present investigation was undertaken by using six generations derived from three different crosses in grass pea...

The uncoupling proteins (UCPs) belong to the mitochondrial inner membrane anion carrier superfamily and play an important role in energy homeostasis. Genetic studies have demonstrated that Ucp2 and Ucp3 gene variants are involved in obesity and metabolic syndrome. The aim of this study was to identify associations between polymorphisms of Ucp2 and Ucp3 genes and economically-important traits in Qinchuan cattle. In the present study, one single-nucleotide polymorphism (SNP) in the 5'UTR region (SNP1:g.C-754G) of the Ucp2 gene was identified by direct sequencing of 441 Qinchuan cattle...

A pair of stripe rust and leaf rust resistance genes was introgressed from Aegilops caudata, a nonprogenitor diploid species with the CC genome, to cultivated wheat. Inheritance and genetic mapping of stripe rust resistance gene in backcrossrecombinant inbred line (BC-RIL) population derived from the cross of a wheat-Ae. caudata introgression line (IL) T291- 2(pau16060) with wheat cv. PBW343 is reported here. Segregation of BC-RILs for stripe rust resistance depicted a single major gene conditioning adult plant resistance (APR) with stripe rust reaction varying from TR-20MS in resistant RILs signifying the presence of some minor genes as well...

Adenosine monophosphate-activated protein kinase (AMPK), an important energy sensor, is crucial for organism survival under adverse conditions. In this study, the roles of this gene under cold stress in a warm-water mud crab, Scylla paramamosain was investigated. The full-length cDNA (SpAMPK) was 1884 bp and its open reading frame of 1566 bp was isolated and characterized. The expressions of SpAMPK detected by quantitative real-time PCR (qRT-PCR) in various tissues revealed that the highest expression was in the hepatopancreas...

Molecular characterization of 23 cytogenetically confirmed XY females was attempted by screening coding regions of SRY and androgen receptor (AR) genes. Five of the index cases showed sequence variations in various exons of the AR gene: a deletion (n.1911delG) and substitutions n.1761G>A and n.1317C>T in exon 1; n.3510C>T transition in exon 6 and deletion mutation (n.3672delT) in exon 7. Four mutations identified here lead to the formation of truncated receptor protein, involving a substantial loss of AR functional domains which explains the phenotype in the subjects...

Acromesomelic dysplasia, type Maroteaux is a disorder characterized by disproportionate short stature predominantly affecting the middle and distal segments of the upper and lower limbs. It is an autosomal recessive disorder due to mutation in NPR2 gene which impairs skeletal growth. To screen the mutations in the gene NPR2, all of its coding exons and splice junction sites were PCR amplified from genomic DNA of affected individuals of four families and sequenced. Four homozygous mutations in four different families were identified...
