ABSTRACT P-bodies are specialized cytoplasmic compartments where translational repression and mRNA turnover may occur. Findings in this issue of Cell provide evidence that P-bodies are sites of "mRNA purgatory." Bhattacharyya et al. (2006) reveal that normal mRNA can be released from P-bodies and translated into protein in response to stress. Meanwhile, Sheth and Parker (2006) report that aberrant mRNAs are targeted to P-bodies to undergo rapid decay.

    ABSTRACT: To survive adverse and ever-changing environmental conditions, an organism must be able to adapt. It has long been established that the cellular reaction to stress includes the upregulation of genes coding for specific stress-responsive factors. In the present study, we demonstrate that during the early steps of the heat stress response, 25% of the Arabidopsis seedling transcriptome is targeted for rapid degradation. Our findings demonstrate that this process is catalyzed from 5' to 3' by the cytoplasmic exoribonuclease XRN4, whose function is seemingly reprogrammed by the heat-sensing pathway. The bulk of mRNAs subject to heat-dependent degradation are likely to include both the ribosome-released and polysome associated polyadenylated pools. The cotranslational decay process is facilitated at least in part by LARP1, a heat-specific cofactor of XRN4 required for its targeting to polysomes. Commensurate with their respective involvement at the molecular level, LARP1 and XRN4 are necessary for the thermotolerance of plants to long exposure to moderately high temperature, with xrn4 null mutants being almost unable to survive. These findings provide mechanistic insights regarding a massive stress-induced posttranscriptional downregulation and outline a potentially crucial pathway for plant survival and acclimation to heat stress.

    ABSTRACT: mRNA degradation is a critical factor in determining mRNA abundance and enables rapid adjustment of gene expression in response to environmental stress. The involvement of processing bodies in stress response suggests a role for decapping-mediated mRNA degradation. However, little is known about the role of mRNA degradation under stressful environmental conditions. Here, we perform a global study of uncapped mRNAs, via parallel analysis of RNA ends (PARE), under cold stress in Brachypodium distachyon. Enrichment analysis indicates that degradation products detected by PARE are mainly generated by the decapping pathway. Endonucleolytic cleavages are detected, uncovering another way of modulating gene expression. PARE and RNA-seq analyses identify four types of mRNA decay patterns. Type II genes, for which light-harvesting processes are over-represented in gene ontology analyses, show unchanged transcript abundance and altered uncapped transcript abundance. Uncapping-mediated transcript stability of light harvesting-related genes changes significantly in response to cold stress, which may allow rapid adjustments in photosynthetic activity in response to cold stress. Transcript abundance and uncapped transcript abundance for type III genes changes in opposite directions in response to cold stress, indicating that uncapping-mediated mRNA degradation plays a role in regulating gene expression. To our knowledge, this is the first global analysis of mRNA degradation under environmental stress conditions in Brachypodium distachyon. We uncover specific degradation and endonucleolytic cleavage patterns under cold stress, which will deepen our understanding of mRNA degradation under stressful environmental conditions, as well as the cold stress response mechanism in monocots.
