Eukaryotic Translation Initiation Factor eIFiso4G Is Required to Regulate Violaxanthin De-epoxidase Expression in Arabidopsis

Autor: Zhong Chen, Blair Jolley, Daniel R. Gallie, Christian Caldwell

Publikováno v: Journal of Biological Chemistry. 289:13926-13936

The eukaryotic translation initiation factor (eIF) 4G is a scaffold protein that organizes the assembly of those initiation factors needed to recruit the 40 S ribosomal subunit to an mRNA. Plants, like many eukaryotes, express two eIF4G isoforms. eIF

Expression of the ethylene biosynthetic machinery in maize roots is regulated in response to hypoxia

Autor: Jane Geisler-Lee, Daniel R. Gallie, Christian Caldwell

Publikováno v: Journal of Experimental Botany

Ethylene regulates plant growth in response to many adverse environmental conditions, including the induction of aerenchyma, i.e. the formation of air spaces, in flooded roots in an effort to maintain oxygen levels. In this work, quantitative RT-PCR

Developmental and Thermal Regulation of the Maize Heat Shock Protein, HSP101

Autor: Christian Caldwell, C. Jane Geisler-Lee, Todd E. Young, Jun Ling, Daniel R. Gallie, Robert L. Tanguay

Publikováno v: Plant Physiology. 127:777-791

The plant heat stress protein, Hsp101, and the yeast ortholog, Hsp104, are required to confer thermotolerance in plants and yeast (Saccharomyces cerevisiae), respectively. In addition to its function during stress, Hsp101 is developmentally regulated

The Phosphorylation State of Translation Initiation Factors Is Regulated Developmentally and following Heat Shock in Wheat

Autor: Robert L. Tanguay, Hanh Le, Karen S. Browning, Nam X. Hoang, Christian Caldwell, Daniel R. Gallie

Publikováno v: Journal of Biological Chemistry. 272:1046-1053

Several translation initiation factors in mammals and yeast are regulated by phosphorylation. The phosphorylation state of these factors is subject to alteration during development, environmental stress (heat shock, starvation, or heme deprivation),

Heat Shock Disrupts Cap and Poly(A) Tail Function during Translation and Increases mRNA Stability of Introduced Reporter mRNA

Autor: Daniel R. Gallie, Letizia Pitto, Christian Caldwell

Publikováno v: Plant Physiology. 108:1703-1713

The effect of heat shock on translational efficiency and message stability of a reporter mRNA was examined in carrot (Daucus carota). Heat shock of short duration resulted in an increase in protein yield, whereas repression was observed following ext

Coat protein enhances translational efficiency of Alfalfa mosaic virus RNAs and interacts with the eIF4G component of initiation factor eIF4F

Autor: Daniel R. Gallie, Ivo M. Krab, John F. Bol, Christian Caldwell

Publikováno v: The Journal of general virology. 86(Pt 6)

The three plus-strand genomic RNAs ofAlfalfa mosaic virus(AMV) and the subgenomic messenger for viral coat protein (CP) contain a 5′-cap structure, but no 3′-poly(A) tail. Binding of CP to the 3′ end of AMV RNAs is required for efficient transl

Analysis of translation elongation factors from wheat during development and following heat shock

Autor: Daniel R. Gallie, Hanh Le, Karen S. Browning, Christian Caldwell

Publikováno v: Biochemical and biophysical research communications. 245(2)

Translational activity in plants undergoes rapid changes during developmental stages such as seed formation and germination, and during abiotic stresses such as heat shock, hypoxia and wounding. We examined the protein levels and isoelectric state of

Arabidopsis thaliana knockout lines for the plant-specific eukaryotic translation initiation factors eIFiso4G1 (i4g1) and eIFiso4G2 (i4g2) genes have been obtained. To address the potential for functional redundancy of these genes, homozygous double
