“…Consistent with this, expression of BRASSINOSTEROID-RESPONSIVE RING-H2 1 (BRH1, At3g61460), whose transcript is downregulated by brassinolide (Molnar et al, 2002), was also downregulated at 6 h after cold stress. We noticed that the expression of many genes with auxinrelated roles was affected by cold stress.…”

To understand the gene network controlling tolerance to cold stress, we performed an Arabidopsis thaliana genome transcript expression profile using Affymetrix GeneChips that contain ;24,000 genes. We statistically determined 939 coldregulated genes with 655 upregulated and 284 downregulated. A large number of early cold-responsive genes encode transcription factors that likely control late-responsive genes, suggesting a multitude of transcriptional cascades. In addition, many genes involved in chromatin level and posttranscriptional regulation were also cold regulated, suggesting their involvement in cold-responsive gene regulation. A number of genes important for the biosynthesis or signaling of plant hormones, such as abscisic acid, gibberellic acid, and auxin, are regulated by cold stress, which is of potential importance in coordinating cold tolerance with growth and development. We compared the cold-responsive transcriptomes of the wild type and inducer of CBF expression 1 (ice1), a mutant defective in an upstream transcription factor required for chilling and freezing tolerance. The transcript levels of many cold-responsive genes were altered in the ice1 mutant not only during cold stress but also before cold treatments. Our study provides a global picture of the Arabidopsis cold-responsive transcriptome and its control by ICE1 and will be valuable for understanding gene regulation under cold stress and the molecular mechanisms of cold tolerance.

“…For example, the RING-finger-type E3 ligases ATL2 and ATL6 were rapidly induced in Arabidopsis plants treated with chitin elicitor [39,40]. Similarly, other members of RING-type E3 ligases such as EL5 from rice and BRH1 from Arabidopsis were also induced after elicitor treatment [41,42]. The upregulation of these genes in plants suggested that they might be involved in the response to biotic stresses.…”

Ubiquitination-mediated protein degradation and modification: an emerging theme in plant-microbe interactions

et al. 2006

Post-translational modification is central to protein stability and to the modulation of protein activity. Various types of protein modification, such as phosphorylation, methylation, acetylation, myristoylation, glycosylation, and ubiquitination, have been reported. Among them, ubiquitination distinguishes itself from others in that most of the ubiquitinated proteins are targeted to the 26S proteasome for degradation. The ubiquitin/26S proteasome system constitutes the major protein degradation pathway in the cell. In recent years, the importance of the ubiquitination machinery in the control of numerous eukaryotic cellular functions has been increasingly appreciated. Increasing number of E3 ubiquitin ligases and their substrates, including a variety of essential cellular regulators have been identified. Studies in the past several years have revealed that the ubiquitination system is important for a broad range of plant developmental processes and responses to abiotic and biotic stresses. This review discusses recent advances in the functional analysis of ubiquitination-associated proteins from plants and pathogens that play important roles in plant-microbe interactions.

“…Based on the presence of either a Cys or His residue in metal ligand position 5, RING finger domains were basically subdivided into the RING-HC (C3HC4) and RING-H2 (C3H2C3) types (Freemont 1993(Freemont , 2000Lovering et al 1993). Recently, many RING-type proteins have been implicated in various biological processes, including photomorphogenesis (COP1 and CIP8) , auxin signaling (SINAT5) (Xie et al 2002), defense signaling (ATL2) (Serrano and Guzman 2004), brassinosteroid response (BRH1) (Molnar et al 2002), seed development (RIE1) (Xu and Li 2003), adaptation to limited nitrogen (NLA) (Peng et al 2007), cold response (HOS1) (Dong et al 2006), ABA signaling (Zhang et al 2005), drought response (DRIP) (Qin et al 2008), drought stress (Rma1H1) (Lee et al 2009), and sugar response (SIS3) (Huang et al 2010).…”

The RING finger protein family plays a crucial role in plant growth and development and in response to biotic and abiotic stresses. However, no detailed information concerning this family is available for apple (Malus × domestica L. Borkh) due to the limited information on whole genome sequences. In this study, 688 RING domains in 663 predicted proteins were identified in apple. Based on the spacing between metal ligands or substitutions at one or more of the metal ligand positions, nine RING types were identified: RING-H2, RING-HC, RING-C2, RING-v, RING-D, RING-S/T, RING-G, RING-mH2, and RING-mHC, in which the first seven types were described previously in Arabidopsis, while the latter two were newly identified in apple. Proteins containing RING finger motifs were further classified into 57 groups according to the different known or unknown domains outside the RING domains. A total of 643 retrieved proteins appear to be distributed over all 17 linkage groups with different densities. Microarray and expressed sequence tag data revealed that only a few of these RING finger proteins may be involved in fruit development. As a first step towards genome-wide analyses of the RING-containing genes in apple, our results provide valuable information for understanding the classification and putative functions of the RING finger gene family in higher plants.
