Cadmium (Cd) is one of the most toxic heavy metals in plants. To investigate whether Cd induces common plant defense pathways, different physiological and molecular reactions, including modifications in glutathione (GSH) level, activity and gene expression of glutathione reductase (GR) enzyme were characterized in roots of hydroponically cultivated-Vicia seedlings during 12, 24 and 48 h. Vicia ...

Tribes Trifolieae and Vicieae along with Cicereae and Galega (Galegeae) form a monophyletic group that has been designated informally as the “vicioid clade”. There is good support from analyses of various molecular data for the clade itself, but relationships of genera within the clade are not fully understood nor has monophyly of the tribes and genera been fully tested. Sequences of the plasti...

Anabaena variabilis ATCC 29413 is a filamentous, heterocyst-forming cyanobacterium that has served as a model organism, with an extensive literature extending over 40 years. The strain has three distinct nitrogenases that function under different environmental conditions and is capable of photoautotrophic growth in the light and true heterotrophic growth in the dark using fructose as both carbo...

Chlorella variabilis strain NC64A is an intracellular photobiont of the ciliate Paramecium bursaria. NC64A was isolated from P. bursaria nearly 50 years ago and was thereafter cultivated outside the host. This study was undertaken to detect changes in its infectivity to P. bursaria and its auxotrophy for growth outside the host induced during long-term cultivation. NC64A can grow in Modified Bo...
