Description:
We investigated the role of cyclic electron flow around photosystem 1 (CEF1) and state transition (ST) in two soybean cultivars that differed in salt tolerance. The CEF1 and maximum photochemical efficiency (Fv/Fm) were determined under control and NaCl (50 mM) stress and the NaCl-induced light-harvesting complex 2 (LHC2) phosphorylation in vitro was analysed in light and dark. NaCl induced the increase of CEF1 more greatly in wild soybean Glycine cyrtoloba (cv. ACC547) than in cultivated soybean Glycine max (cv. Melrose). The Fv/Fm was reduced less in G. cyrtoloba than in G. max after 10-d NaCl stress. In G. cyrtoloba, the increase of CEF1 was associated with enhancement of LHC2 phosphorylation in thylakoid membrane under both dark and light. However, in G. max the NaCl treatment decreased the LHC2 phosphorylation. Treatment with photosynthetic electron flow inhibitors (DCMU, DBMIB) inhibited LHC2 phosphorylation more in G. max than in G. cyrtoloba. Thus the NaCl-induced up-regulation in CEF1 and ST might contribute to salt resistance of G. cyrtoloba. and K. X. Lu ... [et al.].

Description:
The Institute of Ethnology of the Faculty of Humanities, Charles University, Prague The institute responded to the political and social changes in 1990s. It follows the modern European and world directions in research activities. Several foreign lecturers (Yale, the Northern Arizona University, the University o Basel) as well as the prominent specialists from the Academy of Sciences and the Náprstek Museum started to participate in the teaching programme. - The aim of the new curriculum is the theoretical and practical preparation for the master´s (in future also bachelor´s). The students gain knowledge of the cultural areas and the ability to work and act in various ethnic and cultural environments. The study consists of two cycles, the second of which is specialized. - The institute is devided into three seminars (general ethnology, European and Czech ethnology, and folklore studies). - Talented students can take part in research felowships abroad. The graduates gain ground as scienific and specialized researchers, in cultural facilities, museums, state bureaucracy, media and in humanity organizations. In present, the institute has for about 150 students, 20 new students are accepted every year. Besides the internal study, combined study is organized in some years.The post-graduate study includes several special courses, the final examination and the viva voce. Post-graduates are methodically tead by supervisors. - The research activities are aimed mainly at the ethnic and athno-cultural problems in Czech lands and in Europe. The institute cooperates with several European institutions. It is also specialized in the Hispanic and American studies, as well theoretical and trans-cultural studies. - The institute publishes the collections of papers Studia Ethnographica. - The director of the institute is doc. František Vrhel, CSc., The Institute of European Ethnography and Ethnology, the Philosophical Faculty of Masaryk University, Brno Seminář pro etnologii a etnografii/Seminar of Ethnography and Ethnology at the Philosophical Faculty of Masaryk University was founded by Professor A. Václavík (1891-1951) in 1946. The formerly independent department changed as well as its name. Since 1964 it was Katedra etnografie a folkloristiky/The Department of Ethnography and Folklore Studies. After 1968 it was a part of historical departments and on 1.1.1991 it regained independence. Now it is called Ústav evropské etnologie/The Institute of European Ethnology. The institute provides five-year MA stude programme with combination of a second subject. There is also a three-year internal and five-year external Ph.D. study programme. The lectures and seminars are complemented by other educative activities. Every year since 1992 has been arranging visits to the regions of the Czech Republic or countries mostly of southern or western Europe. Some of these travels were thematic, e.g. Rhetoromans´ foosteps, Semana santa in Spain, Almatrieb in Alps. All these travels are documented on the videotape and slides, so that this material can be used for teaching purposes later. The departmental library serves for studens as well for teachers. It contains more than 13,000 volumes of the basic ethnographical literature. The outcomes of the student and teacher research can be found in the departmental archives. The scholars of he department took part in the Národopisná encyklopedie Čech, Moravy a Slezska/ Ethnographic Encyclopaedia of Bohemia, Moravia and Silesia. The second important work is Vlastivěda moravská/The History and Geography of Moravia, volume 10 Lidová kultura na Moravě/The Folk Culture in Moravia.(2000). The head of the department is Professor PhDr. Richard Jeřábek, DrSc., The Department of Social and Cultural Anthropology of the Faculty of Humanities, Plzeň The department belongs to the newest university departments in the Czech Republic. It originally worked as a part of the Centre of Humanities of the Faculty of Law of the West-Bohemian University. Since 1997 it is a part of the Faculty of Humanities. - This pedagogical and research institution organizes a three-years bachelor course and a continuing two-year master course. The curriculum is based on the credit system and it is complementary with the offer of other university programmes. A part of the department is formed by the seminar of physical anthropology and of the anthropology of the Near East. Social anthropology is understood as a bio-social discipline, inspired especially by the Anglo-American approach. The department cooperates with several scientific institutions both in the Czech Republic and abroad. The research activities are aimed at the problems of rural and urban communities, multiculturalism, applied social anthropology, museum studies, and some topics of religious studies and symbolical anthropology. - The department director is RNDr. Ivo Budil, Ph.D., and Anglické abstrakty s šiframi (št) - abstrakt 1 a 3 a (lv) - abstrakt 2 jsou uvedeny na str. 193-195.
