The xeroderma pigmentosum complementation group B (XPB) protein is involved in both DNA repair and transcription in human cells. It is a component of the transcription factor IIH (TFIIH) and is responsible for DNA helicase activity during nucleotide (nt) excision repair (NER). Its high evolutionary conservation has allowed identification of homologous proteins in different organisms, including plants...
Transcripts of SFR2, a member of the S family of receptor kinase genes, accumulate rapidly in Brassica oleracea leaves in response to wounding, bacterial infection and following treatment with salicylic acid (SA). Expression of a chimeric gene consisting of the SFR2 5′ flanking sequence fused to the gusA reporter gene is also induced in wounded and SA-treated Arabidopsis plants indicating that the...
A two-hybrid screen with the translation initiation factor, eIF(iso)4E from Arabidopsis, identified a clone encoding a lipoxygenase type 2 [Freire, M.A., et al., 2000. Plant lipoxygenase 2 is a translation initiation factor-4E-binding protein. Plant Molecular Biology 44, 129–140], and three cDNA clones encoding the homologue of the mammalian BTF3 factor, the β subunit of the nascent polypeptide-associated...
