The E subunit of photosystem I is not essential for linear electron flow and photoautotrophic growth in Arabidopsis thaliana / A. Inhatowicz, P. Pesaresi, D. Leister. - In: PLANTA. - ISSN 0032-0935. - 226:4(2007 Sep), pp. 889-895.
Abstract:
PSI-E is part of the stromal side of photosystem
I (PSI). In Arabidopsis thaliana, the two nuclear genes
PsaE1 and PsaE2 code for PSI-E, and transcripts of PsaE1
are markedly more abundant than PsaE2 transcripts. Stable
null alleles of the two PsaE genes, psae1-3 and psae2-1,
were identiWed and characterised. The psae2-1 mutant
exhibited wild-type like PSI-E abundance and photosynthetic
performance, whereas in the psae1-3 mutant PSI-E
accumulation was decreased by 85%, together with an
impaired thylakoid electron Xow and plant growth rate. The
psae1-3 psae2-1 double mutant totally lacked PSI-E but
was still able to grow photoautotrophically, implying that
PSI-E is not essential for PSI accumulation and thylakoid
electron flow
