Areca (Areca catechu L) Raw sequence reads

Areca (Areca catechu L), one of the four primary medicinal plants in south China. The present paper of areca nut aims to provide an up-to-date review on physiological and biochemical, biocontrol bacteria, active ingredients and pharmacology, processing and utilization. However, little research has been done on the molecular mechanisms of fruit development and secondary biomass formation. In this study, high-throughput sequencing technology was used to sequence the transcriptome of peel and seeds in different periods to find differentially expressed genes in different developmental stages of betel nut. Sequencing identified 259,401 transcript sequences in which 35,806 single gene sequences were annotated in the database. Among the betel nut peels, 4,491 differential genes were divided into 3 major categories and 45 subclasses in GO data, of which 617 differential genes were involved in 111 KEGG metabolic pathways (including 82 biological processes and five secondary metabolic pathways). There are 5,443 differential genes in the betel nut seeds, which are enriched in three major categories and 48 subclasses in the GO database. aAccording to the KEGG pathway annotation results, 898 differential genes are involved in 118 pathways (including 89 biological processes, seven secondary metabolic pathways). The comparison of different tissues of the peel and the seeds showed that the secondary metabolic regulation related genes in the peel showed a down-regulated expression trend with the development of the fruit, while the secondary metabolic regulation related genes of the seeds showed an up-regulated expression trend.Further analysis showed that with the development of fruit, 80% of the secondary metabolic pathways in the pericarp showed a down-regulated expression of the genes, while 71.4% of the secondary metabolic pathways in the seeds showed up-regulated expression. The results of the study preliminarily revealed the overall characteristics of the transcriptome of different tissues and different developmental stages of areca nut, and found that the expression of secondary metabolism-related regulatory genes in betel nut and pit were observed in different stages, which was the medicinal development and secondary of betel nut. The molecular regulation study of biosynthesis synthesis laid the foundation
