Disease relevance of PsaL

  • Growth and photosynthetic characteristics of a selected mutant strain under photoautotrophic conditions were similar to those of the wild type, suggesting that the function of PsaL is dispensable for photosynthesis in Synechocystis sp. PCC 6803 [1].

High impact information on PsaL


Analytical, diagnostic and therapeutic context of PsaL

  • Southern blot analysis indicates that PsaL is a single copy gene [2].
  • Northern blot analysis shows that the expression of the PsaL gene is light-induced similar to other of the barley photosystem I genes [2].
