Abstract
Trehalose plays an important role in metabolic regulation and abiotic stress tolerance in plants. Trehalose contents are potentially modulated by trehalose-6-phosphate synthase (TPS), which is a key enzyme in the trehalose biosynthetic pathway. Using available wheat expressed sequence tag sequence information from NCBI and two wheat genome databases, we identified 12 wheat TPS genes and performed a comprehensive study on their structural, evolutionary and functional properties. The estimated divergence time of wheat TPS gene pairs and wheat-rice orthologues suggested that wheat and rice have a common ancestor. The number of TPS genes in the wheat genome was estimated to be at least 12, which is close to the number found in rice, Arabidopsis and soybean. Moreover, it has been reported earlier in other plants that TPS genes respond to abiotic stress, however, our study mainly analysed the TPS gene family under freezing conditions in winter wheat, and determined that most of the TPS gene expression in winter wheat was induced by freezing conditions, which further suggested that wheat TPS genes were involved in winter wheat freeze-resistance signal transduction pathways. Taken together, the current study represents the first comprehensive study of TPS genes in winter wheat and provides a foundation for future functional studies of this important gene family in Triticeae.

Abstract
Cytochrome P450-1B1 (CYP1B1) is a major enzyme catalyzing the formation of genotoxic 4-hydroxyestradiol. This enzyme is also involved in the activation of polycyclic aromatic hydrocarbons and heterocyclic aromatic amines, mammary carcinogens in experimental animals. CYP1B1 is genetically polymorphic, and the variations in the CYP1B1 gene may be related to the risk of breast cancer. We evaluated this hypothesis among 186 breast cancer cases and 200 age-matched controls as part of a large population-based case-control study conducted in urban Shanghai during 1996 to 1998. Genomic DNA from cases and controls was analyzed for genetic polymorphism in codon 432 (Val-->Leu) of the CYP1B1 gene using a PCR-RFLP-based assay. The frequency of the Leu allele was 53% in cases and 46% in controls (P = 0.06). Compared with those with the Val/Val genotype, women with the Leu/Leu genotype had a 2.3-fold [95% confidence interval (CI), 1.2-4.5] elevated risk of breast cancer after adjusting for potential confounding variables. This positive association was more pronounced among postmenopausal women (Odds ratio, 3.1; 95% CI, 1.0-9.1) than premenopausal women (OR, 1.9; 95% CI, 0.8-4.3). Elevated risks of breast cancer associated with homozygosity for the Leu allele were observed in virtually all subgroups of women defined by major risk factors for breast cancer. The results from this study were consistent with recent findings from in vitro and animal experiments implicating a potentially important role of CYP1B1 in the etiology of human breast cancer.

Abstract
The result of most association studies and linkage analyses have suggested a negative association between schizophrenia and D2-like (D2, D3, and D4) receptor polymorphisms. Although the polymorphisms of the D2-like receptor in themselves may not account for the etiology of schizophrenia, they can contribute to the severity of the symptoms. Thus, we studied the associations between the polymorphisms and their combinations, and the vulnerability of schizophrenics. Fragments of the D2-like receptor genes were amplified by means of the polymerase chain reaction, and the polymorphisms were identified by the restriction fragment length polymorphism and single-stranded conformation polymorphism methods. There were no statistically significant differences in the polymorphisms and their combinations between schizophrenics and controls. Schizophrenics with D4E1(A1/A2), which contains 2 and 1 tandem repeats of a 12-base-pair sequence in exon 1, had a lower total positive symptom score before medication than schizophrenics with D4E1(A1/A1). There was no association between the polymorphisms and negative symptoms.

Abstract
Genes that regulate serotonergic (5-HT) systems may underlie the etiology of schizophrenia. In this study the gene encoding the 5-HT2A receptor in schizophrenics and healthy controls was examined. First, we sequenced all exons and the flanking introns of the 5-HT2A receptor gene in 10 schizophrenics and 10 controls. The substitution of C for T at position 102 in exon, which had been reported by Warren et al. (1993), was confirmed. Restriction fragment length polymorphism (RFLP) analysis revealed no association between polymorphism and schizophrenia. There was no association between the polymorphism and subdiagnosis, family history, age of onset, amounts of antipsychotics, or positive and negative symptoms before or after medication. Other polymorphisms in the gene were screened in 100 schizophrenics by the single-strand conformation polymorphism method, but none was found. Our results suggest that an abnormality in the 5-HT2A receptor gene in schizophrenia is unlikely.

Abstract
We studied the 5-HT1A receptor gene in 50 mood disorders and 50 normal volunteers. The 5-HT1A receptor gene was amplified by polymerase chain reaction and sequenced by the dideoxy method. The sequence of the 5-HT1A receptor encodes a protein of 422 amino acids, that is, one amino acid longer than the reported sequence (Kobilka et al. 1987). The DNA sequence at positions 454 to 459 is CGC GCC GCT, not CCG CGT, and the amino acids sequence at these positions is changing from proline arginine to arginine alanine alanine. These differences, however, were observed in both mood disorders and controls. One silent polymorphism, CTG to GTA at position 294, was found. These results suggest that the 5-HT1A receptor gene is intact in mood disorders.

Abstract
mtDNA genotypes of six domestic horses (three adult short horses whose heights are under 1 m and three common domestic horses) from a small region of 15 km2 in Malipo county of Yunnan province of China were investigated by the technique of restriction fragment length polymorphism (RFLP) with 16 restriction endonucleases which recognize 6-bp sequences. An average of 56 fragments for an individual was obtained. Unlike other domestic animals, this population of horses exhibits high mtDNA genetic diversity. Each of the six horses has a specific mtDNA genotype showing a pattern of multiple maternal origins, as suggested by fossil and literature records. We think the population of horses is an amazing seed-resource pool of horses and hence deserves to be paid more attention from the view of conservation genetics. However, it is also remarkable that we did not find any typical mtDNA genetic markers which would discriminate between short horses and common domestic horses.
