The species evolved on mainland Australia and its wind-dispersed seeds are thought to be capable of traversing long distances over oceans due to their high physical dormancy. (hop bush) is a dioecious woody shrub with a worldwide distribution across six continents, spanning from 33°N (in California) to 44°S (in New Zealand’s South Island). A wide range of putative gene regions were identified along with a large set of variable SNP markers, providing a basis for studies into the evolution and ecological adaptation of D. Genetic differences among morphologically distinct subspecies were found. viscosa,providing a comprehensive transcriptomic reference. We have established a significant genomic data resource for D. Across all samples, 248,235 SNPs were detected. The subspecies comparison identified 8,494 fixed SNP differences across 3,979 contiguous sequences, indicating a level of genetic differentiation between them. Gene Ontology terms were assigned to 28,440 contigs and KEGG analysis identified 146 pathways that the gene products from 5,070 contigs are potentially involved in. Contigs with significant BLAST alignments (E value < 1e -5)numbered at 44,191, with 38,311 of these having their most significant hits to sequences from land plant species. Illumina sequencing returned 268,672,818 sequence reads, which were de novoassembled into 105,125 contigs. A comparison between the two subspecies was also carried out.
Single nucleotide polymorphisms were detected for the establishment of a genetic marker set. Contiguous sequences (contigs) were annotated using BLAST searches against the NCBI non-redundant database and gene ontology definitions were assigned. Sequenced reads were assembled to provide a transcriptome resource. angustissima and spatulata distributed along an environmental gradient in South Australia. We performed Illumina sequencing of cDNA prepared from leaf tissue collected from seven populations of D. Here, we present a comprehensive transcriptome dataset for future genomic studies into this species. Limited genomic resources are currently available for this species, thus our understanding of its evolutionary history and ecological adaptation is restricted.
It evolved in Australia where it is found over a wide range of habitat types and is an ecologically important species.
The hop bush, Dodonaea viscosa, is a trans-oceanic species distributed oversix continents.
