چکیده انگلیسی
Areca catechu L. belongs to the Arecaceae family which comprises many economically important palms. The palm is a source of alkaloids and carotenoids. The lack of ample genetic information in public databases has been a constraint for the genetic improvement of arecanut. To gain molecular insight into the palm, high throughput RNA sequencing and de novo assembly of arecanut leaf transcriptome was undertaken in the present study. A total 56,321,907 paired end reads of 101â¯bp length consisting of 11.343 Gb nucleotides were generated. De novo assembly resulted in 48,783 good quality transcripts, of which 67% of transcripts could be annotated against NCBI non - redundant database. The Gene Ontology (GO) analysis with UniProt database identified 9222 biological process, 11268 molecular function and 7574 cellular components GO terms. Large scale expression profiling through Fragments per Kilobase per Million mapped reads (FPKM) showed major genes involved in different metabolic pathways of the plant. Metabolic pathway analysis of the assembled transcripts identified 124 plant related pathways. The transcripts related to carotenoid and alkaloid biosynthetic pathways had more number of reads and FPKM values suggesting higher expression of these genes. The arecanut transcript sequences generated in the study showed high similarity with coconut, oil palm and date palm sequences retrieved from public domains. We also identified 6853 genic SSR regions in the arecanut. The possible primers were designed for SSR detection and this would simplify the future efforts in genetic characterization of arecanut.
