Glutamate-dehydrogenase (GDH, EC activity and isoenzyme patterns were investigated in Arabidopsis thaliana plantlets, and parallel studies were carried out on glutamine synthetase (GS, EC Both NADH-GDH and NAD-GDH activities increased during plant development whereas GS activity declined. Leaves deprived of light showed a considerable(More)
The kinetics of the acquisition and loss of the use of olfactory and visual cues were previously obtained in six experimental colonies of the ant Myrmica sabuleti meinert 1861, under normal conditions. In the present work, the same experiments were conducted on six other naive identical colonies of M. sabuleti, under electromagnetic radiation similar to(More)
Protoplasts have usually been presented as a methodological tool. Even as such, they make possible an impressive array of applications in plant biology. Here we report on the use of protoplast-derived selectable markers in the study of several disturbed genetic systems with obvious effects on plant development: (1) auxotrophic mutants and the control of(More)
This paper summarizes our findings on the eye morphology, visual perception, learning abilities, navigation system and recruitment strategy of three Myrmica species, pointing out the agreement between each species’ morphological, physiological and behavioral characters as well as the accordance between these characters and each species’ environmental(More)
