▪ Abstract Photosystem I is the light-driven plastocyanin-ferredoxin oxidoreductase in the
thylakoid membranes of cyanobacteria and chloroplasts. In recent years, sophisticated …

Oxygenic photosynthesis is driven via sequential action of Photosystem II (PSII) and (PSI)
reaction centers via the Z-scheme. Both of these pigment–membrane protein complexes are …

The ETR1 receptor from Arabidopsis binds the gaseous hormone ethylene. A copper ion
associated with the ethylene-binding domain is required for high-affinity ethylene-binding …

Barcoded mutant libraries are a powerful tool for elucidating gene function in microbes,
particularly when screened in multiple growth conditions. Here, we screened a pooled …

The chloroplast genes ycf3 and ycf4 from the green alga Chlamydomonas reinhardtii have
been characterized. The deduced amino acid sequences of Ycf4 (197 residues) and Ycf3 …

Plants harvest light energy by oxygenic photosynthesis, which is undoubtedly one of the
most important biological processes on the earth. By liberating oxygen, consuming carbon …

The known envelope membrane proteins of the chloroplastic protein import apparatus lack
sequence similarity to proteins of other eukaryotic or prokaryotic protein transport systems …

Type I reaction centers (RCs) are multisubunit chlorophyll–protein complexes that function in
photosynthetic organisms to convert photons to Gibbs free energy. The unique feature of …

In Arabidopsis thaliana, the D‐subunit of photosystem I (PSI‐D) is encoded by two functional
genes, PsaD1 and PsaD2, which are highly homologous. Knock‐out alleles for each of the …

Quantifying cellular components is a basic and important step for understanding how a cell
works, how it responds to environmental changes, and for re-engineering cells to produce …
