... whereas the increase in total cell fatty acids was attributable to the synthesis of new cyto- plasmic material, such as mitochondria. Of particular interest was the marked ... particularly to a diminution of the number of mitochondria per cell. Since we have already demonstrated that, in higher plant cells, cardioplipin and cytochrome aa 3...

... reason the aim of our research was to demonstrate this cause-and-effect relationship and to quantify the effect of damage on forking. We took advantage of a young open exper- imental beech plantation ... which was much sig- nificant than the other variables and factors available. Thus overall, the damage factor had both a statistical and a causal value, i.e. functional and more p...
