Subategory:

Mutants

Description:

A collection of over 350 acetate-requiring mutants was screened for those that could be rescued with 5% CO₂ in air. This is one of seven genetically-independent mutants that was recovered. It grows on minimal medium at 25 °C, but dies on minimal medium at 35 °C. It can be rescued on minimal medium at 35 °C with 5% CO₂ in air. It may be defective in the CO₂-concentrating mechanism (CCM), but has not been analyzed. This nuclear mutant has been maintained with acetate medium in darkness since its isolation.

Species:

Chlamydomonas

Phenotype:

Requires elevated CO₂ for photosynthetic growth at 35 °C
