Gene: psaA
Genes and Mutantsposted by Wim Vermaas <wim at asu.edu> at 1998-03-16
GeneNamepsaA
ProductNamePS I reaction center protein
FunctionPsaA and PsaB form the PS I reaction center heterodimer
GeneticBackgroundNot examined
DNAno
Phenotypeyes
PhenotypeDetailsDeletion of psaA and psaB leads to a light-sensitive phenotype.Mutants can be propagated at 5 umol photons/m2/s.Additional deletion of apcE leads to a less light-sensitive phenotype.Mutant characterization data indicate that in the absence of PS I, PS II-generated electrons flow to the cytochrome oxidase in the thylakoid; this oxidase may have a lower electron acceptance capacity than PS I, and overreduction of the PQ pool appears to be harmful to the cell:hence the light-sensitive phenotype of the psaAB- strain.

Mutant: ADK9
Genes and Mutantsposted by Lee McIntosh <mcintos1 at pilot.msu.edu> at 1998-04-03
MutantNameADK9
GeneNamepsaA
ProductNamePhotosystem I P700 apoprotein subunit Ia
FunctionA subunit of photosystem I
GeneticBackgroundNot examined
DNAyes
Phenotypeyes
PhenotypeDetailsUnable to grow photoautotrophically. No accumulation of PSI. Greatly reduced chlorophyll per cell, resulting in a turquoise blue phenotype. Near wild-type levels of PSII per cell.
