Green Roots: Photosynthesis and Photoautotrophy in an Underground Plant Organ [PDF]

Plant Physiology, 1993
The potential for photosynthetic and photoautotrophic growth was studied in hairy root cultures of Asteraceae and Solanaceae species. Upon transfer to light, initially heterotrophic root cultures of Acmella oppositifolia and Datura innoxia greened rapidly, differentiated chloroplasts, and developed light-dependent CO2 fixation in the cortical cells ...

Nickel regulation of photoautotrophy in a cyanobacterium

Water, Air, and Soil Pollution, 1990
Ni inhibited photoautotrophic growth, nitrogenase activity, oxygenic photosynthesis (O2-evolution, 14CO2-uptake) and respiratory O2-uptake in the diazotrophic cyanobacterium, Nostoc muscorum. 14CO2-uptake was more sensitive to Ni compared to nitrogenase activity, O2evolution or respiratory O2-uptake.

Horizontally Acquired Nitrate Reductase Realized Kleptoplastic Photoautotrophy of Rapaza viridis

Plant And Cell Physiology, 2023
Abstract While photoautotrophic organisms utilize inorganic nitrogen as the nitrogen source, heterotrophic organisms utilize organic nitrogen and thus do not generally have an inorganic nitrogen assimilation pathway. Here, we focused on the nitrogen metabolism of Rapaza viridis, a unicellular eukaryote exhibiting kleptoplasty.

Archean Photoautotrophy: Some Alternatives and Limits

Origins of Life, 1979
From the Archean geological record, one can infer that photoautotrophy evolved early in earth history; however the nature of this photosynthesis -- whether it was predominately or cyanobacterial -- is less clearly understood. General agreement tht the earth's atmosphere did not become oxygen rich before the Early Proterozoic era places constraints on ...

Poly‐β‐hydroxybutyrate accumulation in cyanobacteria under photoautotrophy

Biotechnology Journal, 2010
AbstractPoly‐β‐hydroxybutyrate (PHB) is a biodegradable and biocompatible polymer that has immense potential in the field of environmental, agricultural and biomedical sciences. An alternative host system has been explored in this study for low‐cost production.

The Effect of Photoautotrophy on Photosynthesis and Photoinhibition of Gardenia Plantlets during Micropropagation

Photosynthetica, 2001
We studied the relationships between the degree of photoautotrophy, photosynthetic capacity, and extent of photoinhibition of Gardenia jasminoides Ellis plantlets in vitro. Two successive micropropagation stages (shoot multiplication and root induction), and three culture conditions [tube cap closure, photosynthetic photon flux density (PPFD), and ...
