Plant RNA editing modifies cytidines (C) to uridines (U) at specific sites in the transcripts of both mitochondria and plastids. Specific targeting of particular Cs is achieved by pentatricopeptide proteins that recognize cis elements upstream of the C that is edited. Members of the RNA-editing factor interacting protein (RIP) family in Arabidopsis have recently been shown to be essential components of the plant editosome. We have identified a gene that contains a pair of truncated RIP domains (RIP-RIP). Unlike any previously described RIP family member, the encoded protein carries an RNA recognition motif (RRM) at its C terminus and has therefore been named Organelle RRM protein 1 (ORRM1). ORRM1 is an essential plastid editing factor; in Arabidopsis and maize mutants, RNA editing is impaired at particular sites, with an almost complete loss of editing for 12 sites in Arabidopsis and 9 sites in maize. Transfection of Arabidopsis orrm1 mutant protoplasts with constructs encoding a region encompassing the RIP-RIP domain or a region spanning the RRM domain of ORRM1 demonstrated that the RRM domain is sufficient for the editing function of ORRM1 in vitro. According to a yeast two-hybrid assay, ORRM1 interacts selectively with pentatricopeptide transfactors via its RIP-RIP domain. Phylogenetic analysis reveals that the RRM in ORRM1 clusters with a clade of RRM proteins that are targeted to organelles. Taken together, these results suggest that other members of the ORRM family may likewise function in RNA editing.

“…atRZ1 mutants are more sensitive to low and freezing temperatures, whereas overexpressing plants are more tolerant to these stresses (Kim et al, 2005). On the basis of these results, Kim et al (2005) concluded that atRZ1 might have an RNA chaperone activity leading to the destabilization of the over-stabilized secondary structures and, thereby, to facilitate an efficient translation at low temperature. Another Arabidopsis protein involved in pre-mRNA processing and cold signaling is STA1.…”

Freezing temperatures are one of the environmental stresses with more impact in plant development in temperate regions. By means of cold acclimation, many plant species are able to increase their freezing tolerance in response to low-nonfreezing temperatures. In the last years, an important effort has been made to characterize the molecular mechanisms that control this adaptive process. Transcriptome analyses indicate that cold acclimation is mainly regulated by low temperatures through changes in gene expression. In this regard, it has been reported that 3.4% of Arabidopsis genes are regulated by low temperature, including 95 genes annotated as transcription factors. The control of coldinducible gene expression is very complex and involves many different signaling pathways that, in some cases, seem to share common intermediates. Interestingly, recent reports have shown that RNA processing and export, as well as post-translational modifications, including ubiquitylation and SUMOylation, also play important roles in regulating cold acclimation. Furthermore, histone modifications seem to be relevant in this regulation. In fact, histone acetylation and deacetylation are needed for correct activation of gene expression in response to low temperatures. All these data reveal that post-transcriptional mechanisms should be taken into consideration when analyzing the control of cold acclimation. Following, is a brief overview of the current understanding on the regulatory mechanisms that ensures the accurate development of this adaptive response.Additional key words: abiotic stress, Arabidopsis, freezing tolerance, low temperature. ResumenRevisión. Mecanismos reguladores implicados en la respuesta de aclimatación al frío Las temperaturas de congelación son uno de los estreses ambientales con mayor impacto en el desarrollo de las plantas en las regiones templadas. Por medio de la respuesta de aclimatación, muchas especies son capaces de incrementar su tolerancia a la congelación en respuesta a temperaturas bajas propiamente dichas. En los últimos años, se ha realizado un gran esfuerzo en la caracterización de los mecanismos moleculares que controlan este proceso adaptativo. Análisis transcriptómicos indican que la aclimatación al frío es regulada principalmente por cambios en la expresión génica. En este sentido, se ha descrito que la expresión de un 3,4% de los genes de Arabidopsis está regulada por las temperaturas bajas, incluyendo 95 genes anotados como factores de transcripción. El control de la expresión génica inducible por frío es muy complejo e implica diferentes rutas de señalización de la señal que, en algunos casos, parecen compartir intermediarios comunes. Trabajos recientes han mostrado que el procesamiento y movilización de RNA, y algunas modificaciones post-traduccionales de proteínas como la ubiquitinación y la SUMOilización también juegan un papel importante en la regulación del proceso de aclimatación a las temperaturas bajas. Más aún, la modificación de histonas parece ser también relevante en ...

“…The amount of zinc finger protein in cells appears to be small under favorable conditions; however, transcription is increased and this protein is among the STREs when unfavorable conditions are encountered. Therefore, STRE-dependent transcriptional induction normally occurs rapidly (Kim et al 2005, Jang et al 2007). In the present study, expression of the gene coding for the zinc finger protein increased 2-fold after heat stress and this increase, together with the enhancement of some regulated factors, strengthened the defense of the organism and reduced the damage to cell function.…”

Suppression subtractive hybridization was used to analyze the differences in gene expression in the body wall of the Japanese sea cucumber Apostichopus japonicus, induced by heat stress (28°C), in order to understand the response at the molecular level. A total of 737 clones was selected and analyzed, and 165 distinct sequences were obtained, with 65 sharing similarity to sequences in public databases. The sequenced genes were classified into 3 functional categories. Increased expression of some genes in response to stress was concomitant with decreased expression of genes concerned with energy production and metabolism. The results (1) suggest that heat stress has significant effects on gene expression in A. japonicus, and (2) provide the basis for further study of molecular regulation mechanisms underlying the response to heat stress and estivation in A. japonicus.
