SesameFG: Sesame Functional Genomics Database

General introduction

As a worldwide grown oilseed crop, sesame has high oil content and contains a stably high proportion of unsaturated fatty acid. It has a small diploid genome and short period of duration, making it an attractive species for genetic studies of oilseed crops. With the advancement of NGS technology, genome sequencing, large-scale genome re-sequencing, genome comparison, transcriptome sequencing, gene family identification and SSR development were carried out for sesame in the last few years. The genetic information which is significant for the functional genomics research of sesame increased tremendously, including the reference genomes, genomic variations, gene expression profiles and SSR markers. To promote the functional genomics research of sesame, the genetic information combined with the comprehensive phenotypic information were collected and integrated in the web-based database, named SesameFG. The current version of SesameFG contains phenotypic information of 705 sesame accessions, de novo assembled genome of three sesame varieties, 5,407,981 SNPs identified from the re-sequencing data of the 705 sesame accessions, gene expression profiles of five tissues, 104,836 genomic-SSR markers, associated peak SNPs and candidate genes of the importance agronomic traits. All phenotypic and genotypic information in SesameFG is available for online query and download freely. Moreover, SesameFG provides useful search function and data mining tools, including genome browse and local BLAST service. In particular, the geographical details, plant images and phenotype information for various sesame accessions, which is extremely valuable for genetic research, were available in this database. SesameFG will be updated regularly with new features, new phenotypic and genotypic information.
