De novo transcriptome assembly of heavy metal tolerant Silene dioica.

ABSTRACT: Silene dioica is a dioecious plant of the family Caryophyllaceae. In the present study, we used Illumina sequencing technology (MiSeq) to sequence, de novo assembly and annotate the transcriptomes of male and female copper tolerant S. dioica individuals. We sequenced the normalized mRNA of roots, shoots, flower buds and flowers for each sex. Raw reads of the transcriptome assembly project for S. dioica male and female individual have been deposited in NCBI's Sequence Read Archive (SRA) database with the accession number SRP094611. The Trinity and Detonate program was used to de novo assembly 92,347 transcripts for male and 94,757 transcripts for female transcriptome. The assembled transcriptome sequences for S. dioica male and female individuals can be accessed at NCBI with the following accession numbers: GFCG00000000 (male); GFCH00000000 (female). The obtained transcriptomic data will be useful for further studies focusing on copper tolerance, comparative transcriptome analysis with other Silene species and sex chromosomes evolution.

Project description:BackgroundSyntrichia caninervis is a desiccation-tolerant moss and the dominant bryophyte of the Biological Soil Crusts (BSCs) found in the Mojave and Gurbantunggut deserts. Next generation high throughput sequencing technologies offer an efficient and economic choice for characterizing non-model organism transcriptomes with little or no prior molecular information available.ResultsIn this study, we employed next generation, high-throughput, Illumina RNA-Seq to analyze the poly-(A)?+?mRNA from hydrated, dehydrating and desiccated S. caninervis gametophores. Approximately 58.0 million paired-end short reads were obtained and 92,240 unigenes were assembled with an average size of 493 bp, N50 value of 662 bp and a total size of 45.48 Mbp. Sequence similarity searches against five public databases (NR, Swiss-Prot, COSMOSS, KEGG and COG) found 54,125 unigenes (58.7%) with significant similarity to an existing sequence (E-value???1e-5) and could be annotated. Gene Ontology (GO) annotation assigned 24,183 unigenes to the three GO terms: Biological Process, Cellular Component or Molecular Function. GO comparison between P. patens and S. caninervis demonstrated similar sequence enrichment across all three GO categories. 29,370 deduced polypeptide sequences were assigned Pfam domain information and categorized into 4,212 Pfam domains/families. Using the PlantTFDB, 778 unigenes were predicted to be involved in the regulation of transcription and were classified into 49 transcription factor families. Annotated unigenes were mapped to the KEGG pathways and further annotated using MapMan. Comparative genomics revealed that 44% of protein families are shared in common by S. caninervis, P. patens and Arabidopsis thaliana and that 80% are shared by both moss species.ConclusionsThis study is one of the first comprehensive transcriptome analyses of the moss S. caninervis. Our data extends our knowledge of bryophyte transcriptomes, provides an insight to plants adapted to the arid regions of central Asia, and continues the development of S. caninervis as a model for understanding the molecular aspects of desiccation-tolerance.
