title: Transcriptome analysis of Gerbera hybrida ray florets: putative genes associated with gibberellin metabolism and signal transduction.
abstract: In this study, the transcriptome of the Gerbera hybrida ray floret was constructed using a high-throughput Illumina sequencing platform. All 47,104 UniGenes with an average length of 845 nt and an N50 equaling 1321 nt were generated from 72,688,546 total primary reads after filtering and assembly. A total of 36,693 transcripts were annotated by comparison with non-redundant National Center for Biotechnology Information (NCBI) protein (Nr), non-redundant NCBI nucleotide (Nt), Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases after removing exogenous contaminated sequences. The majority of the genes that are associated with gibberellin metabolism and signal transduction were identified. The targets for signal transduction of other plant hormones were also enumerated. Our study provides a systematic overview of the hormone signal transduction genes that are involved in ray floral development in Asteraceae and should facilitate further understanding of the crucial roles of phytohormones in plant growth.
