[Application of case-based method in genetics and eugenics teaching].

Genetics and Eugenics is a cross-discipline between genetics and eugenics. It is a common curriculum in many Chinese universities. In order to increase the learning interest, we introduced case teaching method and got a better teaching effect. Based on our teaching practices, we summarized some experiences about this subject. In this article, the main problem of case-based method applied in Genetics and Eugenics teaching was discussed.

[The exploration and implication of the concept map in genetics teaching.].

The concept map is a kind of chart used to represent and reveal the relationship among the knowledge structures. In genetics teaching, selectively using the concept map can help teachers to organize and review the course contents and also to detect students' academic achievement. It can also promote students' cognitive level, assist students to establish a system integrated knowledge hierarchy, etc. The exploration and implication of concept map in genetics teaching are reviewed in this paper.

[Exploration and practice of genetics teaching assisted by network technology platform].

More teaching techniques have been brought out gradually along with the development of new technologies. On the basis of those traditional teaching methods, a new platform has been set up by the network technology for teaching process. In genetics teaching, it is possible to use the network platform to guide student studying, promote student's learning interest and study independently by themselves. It has been proved, after exploring and applying for many years, that network teaching is one of the most useful methods and has inimitable advantage comparing to the traditional ones in genetics teaching. The establishment of network teaching platform, the advantage and deficiency and relevant strategies were intro-duced in this paper.

[Progress of RNA amplification].

The technology of RNA amplification is developing with the application of gene chip and it is not only adapted for chip hybridization, but also applied in other purposes as well. The methodologies of RNA amplification were reviewed, focused on linear, exponential and linear plus exponential amplifications. The amplification of microRNA was also introduced and a prospect of RNA amplification was made.

[Application of laser capture microdissection in plant genomic research].

To a large degree, the growth and development of plants depend on the organ and/or cell type-specific expression of genes. However, it can be difficult to obtain sufficient number of specific cells from any developmental stage to analyze expression of genes. Laser capture microdissection (LCM) is a novel technique that allows us to collect pure targeted cell subgroup or even a single cell quickly and precisely, thus the problem of tissue heterogeneity in molecular analysis can be resolved successfully. In this paper, the principles of LCM were introduced and the application of LCM in plant was summarized in gene expression analysis, proteomics and plant-microbe interaction. Meanwhile, possible directions of LCM in plant were put forward.
