High impact information on psbA

Truncated forms of the psbA gene were translated and stable ribosome nascent chain complexes were purified [1].
In addition, the accumulation of chloroplast transcripts in these cells and/or tissues (e.g., transcripts for QB binding protein of photosystem II [psbA] and large subunit of ribulose bisphosphate carboxylase [rbcL]) was negatively correlated with the accumulation of CND41 [2].
Nuclear transcriptional activity of the tobacco plastid psbA promoter [3].
We have constructed a tobacco psbA gene deletion mutant that is devoid of photosystem II (PSII) complex [4].
Selection of an atrazine-resistant tobacco cell line having a mutant psbA gene [5].

Biological context of psbA

Nucleotide sequencing revealed that the resistant cell line had a point mutation in its chloroplast psbA gene [5].
Deletion of the tobacco plastid psbA gene triggers an upregulation of the thylakoid-associated NAD(P)H dehydrogenase complex and the plastid terminal oxidase (PTOX) [4].
Possible reasons for the influence of the 5'UTR of the tobacco psbA on mRNA stability and translation efficiency are discussed [6].
In this study, we have used chloroplast transformation and site-directed mutagenesis to analyse the functions of the 5'UTRs of tobacco psbA and rbcL fused to the coding region of the reporter gene uidA [6].
