Physiological changes in the photosynthesis,respiration and cell division of Chlamydomonasreinhardtii, a freshwater green alga, in response to adenine nucleotideswere investigated. In advance of this investigation, two adenine nucleotides, di2-O-methyl-cyclicbis3-5-diadenylic acid 1 and its N-benzoyl-protected analog 2 were synthesized from the commerciallyavailable adenosine phosphoramidite. The respective analogs significantlypromoted the cell division cell number of C.reinhardtii strains 137c mt+ and BR mt+. Moreover,they significantly enhanced the O2 evolution photosynthesis and O2 uptake respiration of both strains. c-di-AMP analogs seem to play aneffective role as a physiological activator in planta.
