Advance of molecular marker application in the tobacco research

Tobacco (Nicotiana spp.) is one of the most important commercial crops in the world. During the last two decades, molecular markers have entered the scene of genetic improvement in different fields of agricultural research. The principles and characteristics of several molecular markers such as RFLP, RAPD, AFLP, microsatellites and minisatellites applied in tobacco genetics and breeding were reviewed. The application and development of molecular marker in tobacco genetic research was presentedemphatically in the following areas: evolutionary genetics, population genetics and genotyping of cultivars, mapping and tagging of genes, and diversity analysis of germplasm. Finally, the perspective of molecular marker’s application in tobacco genetic breeding in the future was discussed

Analytical technology aided optimization and scale-up of impinging jet mixer for reactive crystallization process

Reactive crystallization is widely used in the manufacture of active pharmaceutical ingredients (APIs). Since APIs often have low solubility, traditional stirred tank reactors and the route of process operation and control using metastable zone width are not effective. The current work investigated the integration of an impinging jet mixer and a stirred tank crystallizer that can take advantage of both the reaction and crystallization characteristics, the focus being on design optimization and scale-up using process analytical techniques based on the Fourier transform Infrared spectroscopy and Focused Beam Reflectance Measurement, as well as X-ray diffraction and particle imaging Morphologi G3. The parameters for process operation and design of the impinging jet mixer were optimized. The research was carried out with reference to the manufacture of an antibiotic, sodium cefuroxime, firstly in a 1L reactor, then a 10L reactor. The crystals produced showed higher crystallinity, narrower size distribution, higher stability and purity

Community succession analysis and environmental biological processes of naturally colonized vegetation on abandoned hilly lands and implications for vegetation restoration strategy in Shanxi, China

Data were collected simultaneously at different succession stages using a space-for-time substitution, and were analyzed using the quantitative classification method (TWINSPAN) and the ordination technique (DCA). The community succession of natural colonized plants on abandoned hilly lands in Shanxi are below: Assoc. Potentilla chinensis + Setaria viridis ¨ Assoc. Artemisia sacrorum + S. viridis + Oxytropis caoraloa ¨ Assoc. A. sacrorum + Artemisia capillaries ¨ Assoc. A. capillaries + Pedivularis shansiensis + Echinops pseudosetifer ¨ Assoc. Hippophae rhamnoides. A. sacrorum + Cleistogenes squarrosa ¨ Assoc. H. rhamnoides + Ostryopsis davidiana.A. sacrorum ¨ Assoc. O. davidiana.A. sacrorum + Dendranthema chanetii ¨ Assoc. Populus davidiana.Caragana korshinskii.A. sacrorum ¨ Assoc. Larix principis-rupprechtii.H. rhamnoides.A. sacrorum. This established a recovery model of natural vegetation on abandoned hilly lands in Shanxi. The structure, composition and life-forms changed significantly during succession. Four indices of species diversity were used to analyze changes in the heterogeneity, dominance, richness and evenness of species during the succession process. The species richness and heterogeneity of plant communities increased significantly, the dominance decreased obviously and the evenness decreased slightly. The analysis of variance (ANOVA) also proved the significance of these five indices. Pioneer species of S. viridis, A. sacrorum, O. caoraloa, A. capillaries, P. shansiensis, E. pseudosetifer, C. squarrosa, H. rhamnoides, O. davidia, C. korshinskii, P. davidiana and L. principis-rupprechtii, etc. colonize successfully and play important roles on the vegetation restoration of abandoned hilly lands.Keywords: Abandoned hilly lands, vegetation community succession, environmental biological process, soil quality
