    ..However, the predicted polypeptide contains a conserved amino acid sequence present in several bacterial, animal, and plant hydrolases and includes a potential ATP/GTP-binding-site motif (P-loop). ..

    ..These results suggest that overexpression of BiP in plants may prevent endogenous oxidative stress. ..

    ..Therefore, NIK-mediated antiviral signaling is also likely to operate in tomato, suggesting that tomato NIKs may be good targets for engineering resistance against tomato-infecting begomoviruses. ..
  5. Silveira A, Trontin C, Cortijo S, Barau J, Del Bem L, Loudet O, et al. Extensive natural epigenetic variation at a de novo originated gene. PLoS Genet. 2013;9:e1003437 pubmed publisher
    ..Taken together, these observations provide a first indication that de novo originated genes might be particularly prone to epigenetic variation in their initial stages of formation. ..
  6. Machado C, Praekelt U, de Oliveira R, Barbosa A, Byrne K, Meacock P, et al. Dual role for the yeast THI4 gene in thiamine biosynthesis and DNA damage tolerance. J Mol Biol. 1997;273:114-21 pubmed
    ..Thus, Thi4 and its plant homolog appear to be dual functional proteins with roles in thiamine biosynthesis and mitochondrial DNA damage tolerance. ..
  7. Capella A, Menossi M, Arruda P, Benedetti C. COI1 affects myrosinase activity and controls the expression of two flower-specific myrosinase-binding protein homologues in Arabidopsis. Planta. 2001;213:691-9 pubmed
    ..The results show that COI1 controls MBP expression in flowers and significantly affects the expression and activity of myrosinase in Arabidopsis. ..
  8. Carvalho C, Fontenelle M, Florentino L, Santos A, Zerbini F, Fontes E. A novel nucleocytoplasmic traffic GTPase identified as a functional target of the bipartite geminivirus nuclear shuttle protein. Plant J. 2008;55:869-80 pubmed publisher
    ..In addition to highlighting the relevance of NIG as a cellular co-factor for NSP function, our findings also have implications for general nucleocytoplasmic trafficking of cellular macromolecules. ..
  9. Francischini C, Quaggio R. Molecular characterization of Arabidopsis thaliana PUF proteins--binding specificity and target candidates. FEBS J. 2009;276:5456-70 pubmed publisher
    ..The results obtained in the present study indicate that the APUM proteins may act as regulators in Arabidopsis through an evolutionarily conserved mechanism, which may open up a new approach for investigating mRNA regulation in plants. ..

    ..However, the mutated promoter construct was much less sensitive to SA than the native NIMIN-1 promoter, indicating that this TGA2-binding motif is directly involved in the modulation of SA-induced NIMIN-1 expression in Arabidopsis. ..

    ..Our SAXS and analytical ultracentrifugation experiments indicated that RACK1 is predominantly a monomer in solution. RACK1 and Ki-1/57(122-413) interact strongly under the tested conditions. ..

    ..Our results indicate that CRYs signal by modulating PIF activity genome wide and that these factors integrate binding of different plant photoreceptors to facilitate growth changes under different light conditions. ..

    ..Thus, the cloned gene, named thi1, is likely to function in the biosynthesis of thiamine in plants. The data presented in this work indicate that thi1 may also be involved in DNA damage tolerance in plant cells. ..
