Temporary expression of the TAF10 gene and its requirement for normal development of Arabidopsis thaliana.

TAF10 is one of the TATA box-binding protein (TBP)-associated factors (TAFs) which constitute a TFIID with a TBP. Initially most TAFs were thought to be necessary for accurate transcription initiation from a broad group of core promoters. However, it was recently revealed that several TAFs are expressed in limited tissues during animal embryogenesis, and are indispensable for normal development of the tissues.

Gene expression in response to endoplasmic reticulum stress in Arabidopsis thaliana.

Eukaryotic cells respond to the accumulation of unfolded proteins in the endoplasmic reticulum (ER). In this case, so-called unfolded protein response (UPR) genes are induced. We determined the transcriptional expression of Arabidopsis thaliana UPR genes by fluid microarray analysis of tunicamycin-treated plantlets.

Abundant expression in vascular tissue of plant TAF10, an orthologous gene for TATA box-binding protein-associated factor 10, in Flaveria trinervia and abnormal morphology of Arabidopsis thaliana transformants on its overexpression.

TAF10 is one of the TATA box-binding protein-associated factors (TAFs), which constitute the TFIID complex. We isolated a plant TAF10 ortholog from a Flaveria trinervia cDNA library, and named it ftTAF10. The ftTAF10 polypeptide contains a histone-fold motif, which is highly conserved among the TAF10s of other organisms.
