“…The gene balance hypothesis predicts that genes that have products that participate in macromolecular complexes or in transcriptional or signalling networks are more likely to be retained (Birchler and Veitia 2007). The PUB-ARM proteins have been shown to function in large complexes during flower development (Liu et al 2012), salt stress (Ni et al 2010;Salt et al 2011) and drought stress (Drechsel et al 2011), and the majority of PUB proteins with an elucidated biological functions belong to this group. In this study, more Group VI (U-box only) and VII (Kinase + U-box) PUB genes were found to be retained in duplicate or triplicate than Group V (U-box + ARM) genes, indicating that Group VI and VII PUB genes may have important roles during plant growth and development.…”

U-box proteins are widely distributed among eukaryotic organisms and show a higher prevalence in plants than in other organisms. Plant U-box (PUB) proteins play crucial regulatory roles in various developmental and physiological processes. Previously, 64 and 77 PUB genes have been identified in Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa), respectively. In this study, 101 putative PUB genes were identified in the Chinese cabbage (Brassica rapa ssp. pekinensis line Chiifu-401-42) genome and compared with other 15 representative plants. By specific protein domains and a phylogenetic analysis, the B. rapa PUB (BrPUB) gene family was subdivided into 10 groups. Localization of BrPUB genes showed an uneven distribution on the ten chromosomes of B. rapa. The orthologous and co-orthologous PUB gene pairs were identified between B. rapa and A. thaliana. RNA-seq transcriptome data of different tissues revealed tissue-specific and differential expression profiles of the BrPUBs, and quantitative real-time PCR analysis showed inverse gene expression patterns of the BrPUB-ARMs in response to cold and heat stresses. Altogether, the identification, classification, phylogenetic analysis, chromosome distribution, conserved motifs, and expression patterns of BrPUBs were predicted and analysed. Importantly, this study of BrPUBs provides a rich resource that will aid in the determination of PUB functions in plant development.

U-box E3 ubiquitin ligases play important roles in the ubiquitin/26S proteasome machinery and in abiotic stress responses. TaPUB1-overexpressing wheat (Triticum aestivum L.) were generated to evaluate its function in salt tolerance. These plants had more salt stress tolerance during seedling and flowering stages, whereas the TaPUB1-RNA interference (RNAi)-mediated knock-down transgenic wheat showed more salt stress sensitivity than the wild type (WT). TaPUB1 overexpression upregulated the expression of genes related to ion channels and increased the net root Na + efflux, but decreased the net K + efflux and H + influx, thereby maintaining a low cytosolic Na + /K + ratio, compared with the WT. However, RNAi-mediated knock-down plants showed the opposite response to salt stress. TaPUB1 could induce the expression of some genes that improved the antioxidant capacity of plants under salt stress. TaPUB1 also interacted with TaMP (Triticum aestivum α-mannosidase protein), a regulator playing an important role in salt response in yeast and in plants. Thus, low cytosolic Na + / K + ratios and better antioxidant enzyme activities could be maintained in wheat with overexpression of TaPUB1 under salt stress. Therefore, we conclude that the U-box E3 ubiquitin ligase TaPUB1 positively regulates salt stress tolerance in wheat.

“…They are widely connected with the plant stress response [8–11, 19, 20]. PUBs play an essential role in drought [21–24], salt stress [21, 25, 26], temperature stress [21, 27], oxidative stress [28], and in the response to phosphate starvation [29]. …”

The Arabidopsis paralogs, PUB46 and PUB48, encoding U-box E3 ubiquitin ligases, are essential for plant response to drought stress

BackgroundPlants respond to abiotic stress on physiological, biochemical and molecular levels. This includes a global change in their cellular proteome achieved by changes in the pattern of their protein synthesis and degradation. The ubiquitin-proteasome system (UPS) is a key player in protein degradation in eukaryotes. Proteins are marked for degradation by the proteasome by coupling short chains of ubiquitin polypeptides in a three-step pathway. The last and regulatory stage is catalyzed by a member of a large family of substrate-specific ubiquitin ligases.ResultsWe have identified AtPUB46 and AtPUB48—two paralogous genes that encode ubiquitin ligases (E3s)—to have a role in the plant environmental response. The AtPUB46, −47, and −48 appear as tandem gene copies on chromosome 5, and we present a phylogenetic analysis that traces their evolution from an ancestral PUB-ARM gene. Single homozygous T-DNA insertion mutants of AtPUB46 and AtPUB48 displayed hypersensitivity to water stress; this was not observed for similar mutants of AtPUB47. Although the three genes show a similar spatial expression pattern, the steady state levels of their transcripts are differentially affected by abiotic stresses and plant hormones.Conclusions AtPUB46 and AtPUB48 encode plant U-Box E3s and are involved in the response to water stress. Our data suggest that despite encoding highly homologous proteins, AtPUB46 and AtPUB48 biological activity does not fully overlap.Electronic supplementary materialThe online version of this article (doi:10.1186/s12870-016-0963-5) contains supplementary material, which is available to authorized users.
