Photosynthesis and the intracellular inorganic carbon pool in the bluegreen alga Anabaena variabilis: Response to external CO2 concentration.

abstract：:A genotype of Trifolium repens L. capable of sustaining high-frequency plant regeneration from long-term (24-month old) cell cultures has been selected. Numerous densely cytoplasmic meristemoids were formed in suspension cultures following the coordinate removal of 2,4-dichlorophenoxyacetic acid (2,4-D) and trichlorop...
