Assembly of photosystem II (PSII) occurs sequentially and requires several auxiliary proteins, such as ALB3 (ALBINO3). Here, we describe the role of theArabidopsis thalianathylakoid membrane protein Tellurite resistance C (AtTerC) in this process. Knockout ofAtTerCwas previously shown to be seedling‐lethal. This phenotype was rescued by expressing TerC fused C–terminally to GFP in theterc–1background, and the resultingterc–1TerC–GFPline and an artificial miRNA‐based knockdown allele (amiR‐TerC) were used to analyze the TerC function. The alterations in chlorophyll fluorescence and thylakoid ultrastructure observed inamiR‐TerCplants andterc–1TerC–GFPwere attributed to defects in PSII. We show that this phenotype resulted from a reduction in the rate ofde novosynthesis of PSII core proteins, but later steps in PSII biogenesis appeared to be less affected. Yeast two‐hybrid assays showed that TerC interacts with PSII proteins. In particular, its interaction with the PSII assembly factor ALB3 has been demonstrated by co‐immunoprecipitation. ALB3 is thought to assist in incorporation of CP43 into PSII via interaction with Low PSII Accumulation2 (LPA2) Low PSII Accumulation3 (LPA3). Homozygouslpa2mutants expressingamiR‐TerCdisplayed markedly exacerbated phenotypes, leading to seedling lethality, indicating an additive effect. We propose a model in which TerC, together with ALB3, facilitatesde novosynthesis of thylakoid membrane proteins, for instance CP43, at the membrane insertion step.
