    ..However, the derepression is not markedly displayed on dark-adaptation of pho1 plants grown in continuous light. These studies, therefore, define the activity of at least one cellular effector involved in regulation of psbP expression. ..

    ..We report here that a chloroplast protein, oxygen-evolving enhancer protein 2 (OEE2), specifically interacts with the cytoplasmic kinase domain of WAK1 and becomes phosphorylated in an AtGRP-3-..
  3. Xu Y, Wang B, Zhu Y. Identification of proteins expressed at extremely low level in Arabidopsis leaves. Biochem Biophys Res Commun. 2007;358:808-12 pubmed
    ..Our results suggest that polyU or similar media may be combined with 2-DE techniques to identify cellular proteins with extremely low transcription levels to fulfill specific research needs. ..

    ..Interestingly, strong interfering RNA suppression of the genes encoding the PsbQ protein (At4g21280 and At4g05180) was found to have no effect on the architecture of thylakoid membranes. ..

    ..Taken together, these results suggest that HHL1 forms a complex with LQY1 and participates in photodamage repair of PSII under high light. ..
  6. Yi X, Hargett S, Liu H, Frankel L, Bricker T. The PsbP protein is required for photosystem II complex assembly/stability and photoautotrophy in Arabidopsis thaliana. J Biol Chem. 2007;282:24833-41 pubmed
    ..This demonstrates that the extrinsic protein PsbP is required for PS II core assembly/stability. ..

    ..These results suggest that Deg proteases on both the stromal and luminal sides of the thylakoid membranes are important for the efficient PSII repair in Arabidopsis (Arabidopsis thaliana). ..

    ..Immunoblot analysis detected no thylakoid membrane proteins such as D1, light-harvesting complex, and OE23 in apg2 plastids, whereas soluble proteins such as rubisco large and small subunits were not decreased...

    ..Three of the identified proteins were common to both screenings. This suggests that HsfB1 and HsfB2b may be involved in complex regulatory networks, which are linked to other stress responses and signaling processes. ..

    ..These results indicate that the losses of the PsbO and PsbP proteins differentially affect separate protein components and different PS II functions and can do so, apparently, in the same plant. ..
