Ubiquitin ligases play a central role in determining the specificity of the ubiquitination system by selecting a myriad of appropriate candidate proteins for modification. The U-box is a recently identified, ubiquitin ligase activityrelated protein domain that shows greater presence in plants than in other organisms. In this study, we identified 77 putative U-box proteins from the rice genome using a battery of whole genome analysis algorithms. Most of the U-box protein genes are expressed, as supported by the identification of their corresponding expressed sequence tags （ESTs）, full-length cDNAs, or massively parallel signature sequencing （MPSS） tags. Using the same algorithms, we identified 61 U-box proteins from the Arabidopsis genome. The rice and Arabidopsis U-box proteins were classified into nine major classes based on their domain compositions. Comparison between rice and Arabidopsis U-box proteins indicates that the majority of rice and Arabidopsis U-box proteins have the same domain organizations. The inferred phylogeny established the homology between rice and Arabidopsis U-box/ARM proteins. Cell death assay using the rice protoplast system suggests that one rice U-box gene, OsPUB51, might act as a negative regulator of cell death signaling. In addition, the selected U-box proteins were found to be functional E3 ubiquitin ligases. The identification and analysis of rice U-box proteins hereby at the genomic level will help functionally characterize this class of E3 ubiquitin ligase in the future.

Dear Editor, The ubiquitin proteasome system （UPS） is a highly regulated mechanism of intracellular protein degradation in eukaryotes. The UPS comprises three key enzymes： ubiquitin-activating enzyme E1, ubiquitin-conjugating enzyme E2, and ubiquitin ligase enzyme E3. There are nearly 1500 E3 ligase genes in rice and Arabidopsis genomes that target substrates for many biological processes for plant growth and tolerance to abiotic and biotic stresses.

Brassinosteroid （BR） regulates diverse physiological and devel- opmental processes in plants （Choudhary et al., 2012）. BR binds to the receptor kinase BRI1 to trigger a phosphorylation/ dephosphorylation cascade, which includes phosphorylation of Brassinosteroid Signaling Kinase 1 （BSK1） and Constitutive Differential Growth 1 （CDG1） by BRI1, phosphorylation of BSU1 by CDG1, and dephosphorylation of BIN2 （a GSK3-1ike kinase） by BSU1 （Kim et al., 2009, 2011; Wang et al., 2014）. Almost all the downstream components of BR signaling are encoded by multiple genes of a family.
