DDRT; Gene cloning; Glycine max; Heterosis; Soybean

Here, we compare the molecular mechanism of soybean heterosis through the differential expression of basic cloning. Specifically, we cloned 22 differentially expressed cDNA fragments from hybrid combinations of Jilin 38 x EXP (which had obvious yield advantages) and their parents. In addition, we compared the homology of these fragments and predicted their functions. Cloning ... more

quantitative trait locus; Quantitative trait locus-environment interaction; Seed length; Seed width; Soybean

Seed length and seed width are an important factor to the soybean yield. So the quantitative trait loci (QTL) location for seed length and seed width could assistant the breeding of soybean. In this study, the QTL underlying seed length and seed width were studied. A recombinant inbred line population of soybeans derived from a cross between the American semi-draft cultivars Charleston ... more

Genetic analysis; RAPD; Wild olives

Genetic similarities and distances between wild-type olives in Turkey were studied using an RAPD-PCR assay. Seven wild olive tree samples were collected from villages in Manisa and Izmir provinces. Genomic DNA was extracted from young leaves and the RAPD-PCR assay was used to generate RAPD markers. Sixty-five random primers obtained from Operon Technologies were tested for the assay (OP- ... more

DNA damage; Genetic analysis; Hair shaft; Mitochondrial DNA; Museum collection; Study skin

The condition of mtDNA in hair shafts preserved in a museum was examined using 30 study skins of masked palm civets, Paguma larvata (Viverridae), collected between 1924 and 2011. Comparisons of extracts from fresh and burnt alum-fixed hair shafts showed that burnt alum, which is commonly used in taxidermy, had no harmful effect on the amount of total DNA and lengths of the mtDNA ... more

Dwarf mutant; Genetic analysis; Gibberellic acid; SSR analysis; Wheat

A spontaneous dwarf mutant of wheat was found in an F5 generation line derived from a cross between Huamai No. 9 and Een No. 1 in 1998; it was named Huaai 01. We characterized the genetic pattern of Huaai 01 and mapped the gene controlling the dwarf trait. This dwarf mutant was found insensitive to exogenous gibberellic acid treatment, based on the length of the first leaf and ... more

Equilibrium point; Genetic analysis; System dynamics model; Th1-Th2

In the human immune system, T-helper cells are able to differentiate into two lymphocyte subsets: Th1 and Th2. The intracellular signaling pathways of differentiation form a dynamic regulation network by secreting distinctive types of cytokines, while differentiation is regulated by two major gene loci: T-bet and GATA-3. We developed a system dynamics model to simulate the differentiation ... more

Dormancy; Genetic analysis; Lactuca sativa

Seed germination and dormancy are complex phenomena that are controlled by many genes and environmental factors. Such genes are indicated by phytohormones that interact with each other, and may cause dormancy or promote seed germination. The objective of this study was to investigate gene expression associated with the biosynthetic pathways of abscisic acid (ABA), gibberellic acid (GA), ... more

Body color; Development; Genetic analysis; Hybrid; Transparent crucian carp

The aim of this study was to investigate the genetic mechanism of the transparent trait in transparent crucian carp. We observed body color development in transparent crucian carp larvae and analyzed heredity of color in hybrids produced with red crucian carp, ornamental carp, and red purse carp. The results showed that the body color of the newly hatched larvae matured into the adult ... more

cDNA-amplified fragment length polymorphism; Mitochondrial phosphate transporter protein; Photoperiod; Soybean

The differential screening method was used to isolate the soy photoperiodic response-related genes and to further elucidate the molecular mechanisms of the soybean photoperiodic response. The light-sensitive species Zhong Dou 24 was used to receive long-time sunshine, short-time sunshine, and natural sunshine treatment. The cDNA-amplified fragment length polymorphism technique was used to ... more

Drought stress tolerance; Gene expression; Real-time PCR; Soybean; Transcription factor

To gain insight into stress-responsive gene regulation in soybean plants, we identified consensus sequences that could categorize the transcription factors MYBJ7, BZIP50, C2H2, and NAC2 as members of the gene families myb, bzip, c2h2, and nac, respectively. We also investigated the evolutionary relationship of these transcription factors and analyzed ... more
