| Abstract: | Changes in the natural environment require an organism to make constant adaptations enabling efficient use of environmental resources and ensuring its success in competition with other organisms. Such adaptations are expressed through various life strategies, largely determined by the rate of consumption and use of available resources, affecting the life-history traits and the related trade-offs. Allocation of available resources must take into consideration the costs of cell maintenance as well as reproduction. Given that carbon metabolism plays a crucial role in resource allocation, yeast living in different ecological niches show various life-history traits. There are a lot of data about life-history strategies in yeast living in various ecological niches; however, the question is whether different life strategies will be noted for yeast strains growing under strictly controlled conditions. Our studies based on three laboratory yeast strains representing different genetic backgrounds show that each of these strains has specified life strategies which are mainly determined by the glucose uptake rate and its intracellular usage. These results suggest that specific life strategies and related differences in the physiological and metabolic parameters of the cell are the key aspects that may explain various features of cells from different yeast strains, either industrial or laboratory. |
