Objective: To research on genetic diversity of different Salvia miltiorrhiza geographical populations in China.
Method: The genetic diversity of 27 S. miltiorrhiza geographical populations from ten provinces in China was estimated using amplified fragment length polymorphism (AFLP) markers. The data of amplified bands were analyzed by the software POPGENE and SPSS.
Result: The ten primers employed produced a total of 528 discernable and reproduceable amplified fragments. There were 476 polymorphic brands. The percentage of polymorphic bands with in different populations was 90.15%. Genetic diversity analysis showed that Neis gene diversity (He) was 0.261 2 and Shannon's genetic diversity index (1) was 0.403 3. The coefficient of gene similarity was 0.504 0-0.789 0 between populations. The cluster map including all samples were obtained by UPGMA. In the map, there were seven cluster groups and one individual outside the groups.
Conclusion: The genetic diversity with in different geographical population of S. miltiorrhiza in China is plentiful.

Introduction: LDL-cholesterol greater than 190 mg/dL indicates severe hypercholesterolemia (HS) of monogenic and/or polygenic origin. Genetic risk scores (GRS) evaluate potential polygenic causes.
Objective: we applied a GRS of 6-SNP (GRS-6) in HS individuals.

Faecal samples were collected from 216 Tibetan pigs and 78 Tibetan Yorkshire (Large White) and 53 tissue samples from Yorkshire from the Linzhi City slaughterhouse. Total RNA was extracted from faeces and fragments of HEV open reading frame 2 (ORF2) detected by reverse transcription and nested polymerase chain reaction (RT-nPCR) and cloned.

Dwarfism is a major trait for developing lodging-resistant rice cultivars. Gamma irradiation-induced mutagenesis has proven to be an effective method for generating dwarf rice mutants. In this research, we isolated a dwarf mutant from Anna R (4) in the M generation and subsequently stabilized the trait through successive selfing of progeny across the M-M generations.

Genetic differentiation in traits is assumed to frequently occur in response to divergent natural selection. For example, developmental traits might respond to differences in climate. However, little is known about when and at which spatial scales environmental differences lead to genetic differentiation, and to what extent there is genetic differentiation also in trait plasticity.
