Photoautotrophy in Gymnodinium breve Davis
Science, 1962Pure cultures of the Florida "red-tide" flagellate required light and carbon dioxide for growth. Multiplication in darkness was not supported by any of a number of organic compounds and mixtures. The ecological importance of micronutrients is suggested.

Isolation of mutants of the cyanobacterium,Anabaena variabilis, impaired in photoautotrophy
Archives of Microbiology, 1978Mutants ofAnabaena variabilis Kutz. that have a decreased ability to grow photoautotrophically have been isolated by a modification of the techniques used to isolate auxotrophic mutants of that filamentous cyanobacterium, and have been stably propagated. Three mutants have a reduced content of phycocyanin and, as determined by in situ assays of partial

Planta, 1981
Protoplasts of a cytoplasmic albino mutant of Nicotiana tabacum L. characterized by a deficient chloroplast genome were fused with protoplasts of a nitrate-reductase deficient mutant (NR(-)) of N. tabacum. Somatic hybrids were obtained where the genome of the NR(-) mutant was complemented by the cytoplasmic albino mutant which could synthesize an ...

Plant Cell, Tissue and Organ Culture, 1996
This paper reports on the fast fluorescence responses of Gardenia jasminoides Ellis plantlets, at two successive stages (shoot multiplication and root induction) of culture in vitro. We test whether plantlets in vitro suffer photoinhibition during culture and whether the degree of photoautotrophy of these mixotrophic plantlets has any effect on the ...

Early atmospheric oxygen levels: constraints from Archaean photoautotrophy
Journal of the Geological Society, 1984Various independent lines of evidence suggest that photoautotrophic carbon fixation is a very ancient process that had attained control of the terrestrial carbon cycle from at least 3.5 Ga (if not 3.8 Ga). Since it is generally accepted that only biological processes could substantially increase the negligible oxygen pressures sustained on
