Evaluation of proportion of individual mRNAs in polysomal complexes in leaves under control and mild dehydration stress (DS) conditions. DS reduces level of mRNA in polysomes (ribosome loading) for most genes. Results suggest transcript sequence features that regulate differential mRNA translation.

(Submitter supplied) Translational control is a key regulatory step in the expression of genes as proteins. In plant cells, translational efficiency of mRNAs differs on different mRNA species, and the efficiency dynamically changes in various conditions. To gain a global view of translational control throughout growth and development, we performed genome-wide analysis of polysome association of mRNA over growth and leaf development in Arabidopsis thaliana by applying the mRNAs in polysome to DNA microarray. more...

(Submitter supplied) Microarray comparisons of transcript level in wild-type Arabidopsis and eif3h mutant plants. Goal: To detect any change in transcript level between WT and eif3h mutant. BACKGROUND: The eukaryotic translation initiation factor eIF3 has multiple roles during the initiation of translation of cytoplasmic mRNAs. However, the contributions of individual subunits of eIF3 to the translation of specific mRNAs remain poorly understood. more...
