The four sessions of the Pre-symposium were devoted to four different aspects of the subject, these form the main divisions of the report. The Pre-symposium was opened with an introductory speech by V.A.Engelhardt. 相似文献

Kinetics of Lethal Adsorption of Colicin E2 by Escherichia coli 总被引:4,自引:2,他引:2
The kinetics of lethal adsorption of colicin E2 by Escherichia coli C6 were studied by means of survivor plots. These were determined by a method which allowed rapid sampling of the reaction mixture and estimation of approximate confidence limits for the plotted data. The results were consistent with the predictions of a hypothetical model that assumed a single-hit mechanism of colicin action upon a bacterial population whose cells varied in their number of specific (lethal) receptors for colicin. The possibility of nonlethal adsorption is discussed. 相似文献

Nuclear export of the large ribosomal subunit requires the adapter protein Nmd3p to provide a leucine-rich nuclear export signal that is recognized by the export receptor Crm1. Nmd3p binds to the pre-60 S subunit in the nucleus. After export to the cytoplasm, the release of Nmd3p depends on the ribosomal protein Rpl10p and the GTPase Lsg1p. Here, we have carried out a mutational analysis of Nmd3 to better define the domains responsible for nucleocytoplasmic shuttling and ribosome binding. We show that mutations in two regions of Nmd3p affect 60 S binding, suggesting that its binding to the subunit is multivalent. 相似文献

Validation of mega-environment universal and specific QTL associated with seed yield and agronomic traits in soybeans 总被引:1,自引:0,他引:1
Laura Palomeque Li-Jun Liu Wenbin Li Bradley R. Hedges Elroy R. Cober Mathew P. Smid Lewis Lukens Istvan Rajcan 《TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik》2010,120(5):997-1003
The value of quantitative trait loci (QTL) is dependant on the strength of association with the traits of interest, allelic
diversity at the QTL and the effect of the genetic background on the expression of the QTL. A number of recent studies have
identified QTL associated with traits of interest that appear to be independent of the environment but dependant on the genetic
background in which they are found. Therefore, the objective of this study was to validate universal and/or mega-environment-specific
seed yield QTL that have been previously reported in an independent recombinant inbred line (RIL) population derived from
the cross between an elite Chinese and Canadian parent. The population was evaluated at two field environments in China and
in five environments in Canada in 2005 and 2006. Of the seven markers linked to seed yield QTL reported by our group in a
previous study, four were polymorphic between the two parents. No association between seed yield and QTL was observed. The
result could imply that seed yield QTL were either not stable in this particular genetic background or harboured different
alleles than the ones in the original mapping population. QTLU Satt162 was associated with several agronomic traits of which lodging was validated. Both the non-adapted and adapted parent
contributed favourable alleles to the progeny. Therefore, plant introductions have been validated as a source of favourable
alleles that could increase the genetic variability of the soybean germplasm pool and lead to further improvements in seed
yield and other agronomic traits. 相似文献
