Background : Lycoris radiata (L. radiata), which belongs to Amaryllidaceae family, is native to Northeast Asia including Korea, Japan, and China. It is known for its high ornamental and medicinal values. Extensive research has been conducted in a several fields, including molecular biology, morphology, pharmacology, physiology, palynology, and chromosomal biology. The plant is notable for its various biological activities, including anti-cancer, anti-malarial, anti-microbial, reduction in blood pressure, anti-inflammatory, cytotoxicity, and neuroprotective effects.
Methods and Results : The results of studies conducted in duplicate revealed the presence of a total of 325,609 and 404,019 unigenes, acquired from 9,913,869,968 and 10,162,653,038 raw reads, respectively, after trimming the raw reads using CutAdapt, assembly using Trinity package, and clustering using CD-Hit-EST. The resulting unigenes were annotated based on the NCBI Non-redundant protein database, as L. radiata is genetically closer to Elaeis guineensis and Phoenix dactylifera. The unigenes of L. radiata were clustered into three major categories: biological processes, cellular components, and molecular functions, with 51 functional sections. A large number of unigenes (203,157 and 224,813 from replicates 1 and 2, respectively) were categorized in the biological process cluster, followed by the cellular component cluster, and the molecular function cluster. With respect to the biological process category, the unigenes were assigned to 23 functional sections. The majority of unigenes were involved in cellular processes. Among the unigenes clustered as the cellular component with 14 sections, most genes were associated with the cell and cell parts. Furthermore, 78,017 and 88,817 unigenes, respectively, matched the molecular function cluster with 14 sections, of which most unigenes were related to binding and catalytic activity.
Conclusion : This study provides functional information of L. radiata and highlights the use of the Illumina platform for transcriptome research.
