Main conclusion Among 247 RsAP2/ERF identified, the majority of the 21 representatives were preferably expressed under drought and heat while suppressed under heavy metals, indicating their potential roles in abiotic stress responses and tolerance. APETALA2/Ethylene-Responsive factor (AP2/ERF) transcription factor (TF) is one of the largest gene families in plants that play a fundamental role in growth and development as well as biotic and/or abiotic stresses responses. Although AP2/ERFs have been extensively characterized in many plant species, little is known about this family in radish, which is an important root vegetable with various medicinal properties. The available genome provides valuable opportunity to identify and characterize the global information on AP2/ERF TFs in radish. In this study, a total of 247 ERF family genes were identified from the radish genome, and sequence alignment and phylogenetic analyses classified the AP2/ERF superfamily into five groups (AP2, ERF, DREB, RAV and soloist). Motif analysis showed that other than AP2/ERF domains, other conserved regions were selectively distributed among different clades in the phylogenetic tree. Chromosome location analysis showed that tandem duplication may result in the expansion of RsAP2/ERF gene family. The RT-qPCR analysis confirmed that a proportion of AP2/ERF genes were preferably expressed under drought and heat stresses, whereas they were suppressed under the ABA and heavy metal stresses. These results provided valuable information for further evolutionary and functional characterization of RsAP2/ERF genes, and contributed to genetic improvement of stress tolerances in radish and other root vegetable crops.

Web application to search protein databases using a translated nucleotide query. Translated BLAST services are useful when trying to find homologous proteins to a nucleotide coding region. Blastx compares translational products of the nucleotide query sequence to a protein database. Because blastx translates the query sequence in all six reading frames and provides combined significance statistics for hits to different frames, it is particularly useful when the reading frame of the query sequence is unknown or it contains errors that may lead to frame shifts or other coding errors. Thus blastx is often the first analysis performed with a newly determined nucleotide sequence and is used extensively in analyzing EST sequences. This search is more sensitive than nucleotide blast since the comparison is performed at the protein level.

View all literature mentionsAn ALL in ONE tool for functional annotation of (novel) sequences and the analysis of annotation data. Blast2GO (B2G) joins in one universal application similarity search based GO annotation and functional analysis. B2G offers the possibility of direct statistical analysis on gene function information and visualization of relevant functional features on a highlighted GO direct acyclic graph (DAG). Furthermore B2G includes various statistics charts summarizing the results obtained at BLASTing, GO-mapping, annotation and enrichment analysis (Fisher''''s Exact Test). All analysis process steps are configurable and data import and export are supported at any stage. The application also accepts pre-existing BLAST or annotation files and takes them to subsequent steps. The tool offers a very suitable platform for high throughput functional genomics research in non-model species. B2G is a species-independent, intuitive and interactive desktop application which allows monitoring and comprehending the whole annotation and analysis process supported by additional features like GO Slim integration, evidence code (EC) consideration, a Batch-Mode or GO-Multilevel-Pies. Platform: Windows compatible, Mac OS X compatible, Linux compatible, Unix compatible
View all literature mentionsDatabase that collects all arabidopsis transcription factors (totally 1922 Loci; 2290 Gene Models) and classifies them into 64 families. It uses not only locus (gene), but also gene model (transcript, protein) and the detail information is for each gene model not for locus. It adds multiple alignment of the DNA-binding domain of each family, Neighbor-Joining phylogenetic tree of each family, the GO annotation, homolog with the Database of Rice Transcription Factors (DRTF). It also keeps old information items such as the unique cloned and sequenced information of about 1200 transcription factors, protein domains, 3D structure information with BLAST hits against PDB, predicted Nuclear Location Signals, UniGene information, as well as links to literature reference.

View all literature mentionsSoftware application that can be used to compare linkage maps obtained from different sources/populations/etc.. It will draw the linkage maps and look for common marker names, these are then connected in the drawing with dashed lines. All neighboring maps are compared in this way. Images can be printed and saved. Orders of the MAPs (ie which map is compared with which other map) can be changed and maps can be flipped (right mouse button). remark: MapComp bears close relationships with the GGT software package (entry from Genetic Analysis Software)

View all literature mentionsA plant small RNA target analysis server which features two important analysis functions: 1) reverse complementary matching between miRNA and target transcript using a proven scoring schema, and 2) target site accessibility evaluation by calculating unpaired energy (UPE) required to ?open? secondary structure around miRNA?s target site on mRNA. PsRNATarget incorporates recent discoveries in plant miRNA target recognition, e.g. it distinguishes translational and post-transcriptional inhibition, and it reports the number of miRNA/target site pairs that may affect miRNA binding activity to target transcript. PsRNATarget is designed for high-throughput analysis of next-generation data with an efficient distributed computing back-end pipeline that runs on a Linux cluster. The server front-end integrates three simplified user-friendly interfaces to accept user-submitted or preloaded miRNAs and transcript sequences; and outputs a comprehensive list of miRNA / target pairs along with the online tools for batch downloading, key word searching and results sorting.
