Homology searches allow identification of new miRNAs due to their relative high conservation in plant species. Here, miRNAs were identified for Amborella trichopoda. Known and unique plant miRNAs from miRBase were BLAST-searched against Expressed Sequence Tag (EST) and Genomic Survey Sequence (GSS) in A. trichopoda. All candidate sequences with appropriate fold back structure were screened by a series of miRNA filtering criteria. Finally, we identified and analysed conservation of 5 potential conserved miRNAs belonging to 5 miRNA gene families from ESTs as well 82 newly identified miRNAs dependant 39 miRNA families from GSSs. Potential target genes of identified miRNAs were identified based on their sequence complementarities to the respective miRNAs using psRNATarget against scaffold assignment of A. trichopoda genome sequences. Totally, 1219 target sites in A. trichopoda genome were identified. From which, 941 (77.19%) were predicted to be the subject of miRNA cleavage and 278 (22.81%) scaffolds were regulated via translational repression of mRNA. From the predicted miRNAs, 18 had no target sequence in A.trichopoda.","PeriodicalId":15630,"journal":{"name":"Journal of Data Mining in Genomics & Proteomics","volume":"16 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2015-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87565652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In total, five hundred eighty-two honeybee workers were sampled from 22 regions of the country. A PCR-RFLP (Polymerase Chain Reaction Restriction Fragment Length Polymorphism) analysis of the mtDNA samples distinguished the honeybee evolutionary lineages and mtDNA haplotypes from each region. Our data revealed the presence of three different honeybee lineages among the studied populations, comprising the African (A), North Mediterranean (C) and West Mediterranean (M) lineages. Eight different mtDNA haplotypes were recorded at various frequencies (A1, A2, A8, A9, A10, A13, C7 and M4). For the first time, our results identified a low genetic introgression (3.1%) of non-local mtDNA haplotypes (C7 and M4) among the local Algerian honeybees, most likely due to the import of foreign honeybees. Notably, the southern Algerian honeybee populations had lower haplotype diversity than the northern populations. Overall, the local North African honeybee subspecies A. m. intermissa and/or A. m.sahariensis seem to be remarkably dominant across northern Algeria.","PeriodicalId":15630,"journal":{"name":"Journal of Data Mining in Genomics & Proteomics","volume":"108 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2015-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73417474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the increasing availability of primary sequences without any structure information, predictions from amino-acid (AA) sequences are essential. The proposed prediction method of structural motifs is a two-step approach based on a structural alphabet. This alphabet allows encoding any 3D structure into a 1D sequence of structural letters (SL). First, basic correspondence rules between AA and SL are learnt through genetic programming. Then, a Hidden Markov Model is learnt for each beforehand identified motif of interest. Finally, a probability to correspond to a given 3D motif for any given amino-acid sequence is provided. The method is applied on ATP binding sites to compare the efficiency of our method to other ones for a classical function. Then, the method ability to learn motifs corresponding to more rarely predicted functions or to other types of motifs is illustrated.","PeriodicalId":15630,"journal":{"name":"Journal of Data Mining in Genomics & Proteomics","volume":"20 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2015-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78567455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this, PubMed is still the primary source of biomedical information even though multiple other databases such as UniProt, Protein Data Bank (PDB) and Reactome exist. Objective: With the available large volume data from high-throughput technologies and multiple databases, finding relevant information for gene-process-phenotype has now become extremely challenging and tedious. No tool is currently available to simultaneously search PubMed and multiple other databases to get holistic information. Moreover, a typical PubMed search returns large number of articles, which need to be manually screened for identifying relevant literature. Hence, we developed BioGyan, a literature mining tool to simplify the combinatorial search for genes, celltypes and cellular processes in PubMed and other relevant databases. Methods: BioGyan uses a robust scoring method to rank articles relevant to user search terms. The scoring method is based on the weighted sum of co-occurrence of gene, process and interactions terms in an abstract. Results: BioGyan retrieves PubMed articles supporting association between queried genes and processes, relevant pathways from pathway databases and 3-dimensional structures from PDB. For easy viewing, all information to the user is available in single window. BioGyan showed an accuracy of 85.46% in predicting relevance of articles to a gene-process association, and performed better than PESCADOR. Conclusion: BioGyan has several key features such as batch query of genes as well as processes, offline reading of articles, export of list of articles as bibliography and flexibility for user to revise the article relevance, making it a vital tool for literature search. Thus, BioGyan is a unique tool that offers holistic search across multiple databases while greatly automating the entire process.","PeriodicalId":15630,"journal":{"name":"Journal of Data Mining in Genomics & Proteomics","volume":"149 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72877183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All living organisms are made up of genes that code for a protein which performs the particular function. Some genes that play an important role in the biocontrol process are known as the biocontrol genes. These genes send some signals which help in secretion of proteins and enzymes that degrade the plant pathogens. These biocontrol genes can be cloned in huge amounts and can be used on large scale for commercial production. Some Trichoderma genes are also helpful in providing resistance to the biotic and abiotic stresses such as heat, drought and salt .The major biocontrol processes include antibiosis, mycoparasitism and providing plant nutrition.","PeriodicalId":15630,"journal":{"name":"Journal of Data Mining in Genomics & Proteomics","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2014-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90074594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
