Genome sequencing of the high oil crop Sesame

Genome sequencing of the high oil crop Sesame

IN AN ARTICLE ENTITLED, “GENOME  SEQUENCING OF THE HIGH OIL CROP SESAME,” PUBLISHED IN THE FEBRUARY 2014 ISSUE OF  GENOME BIOLOGY, XIURONG ZHANG AND 23 OF HIS ASSOCIATES HAVE  REPORTED A HIGH-QUALITY GENOME SEQUENCE OF SESAME (SESAMUM INDICUM L. ASSEMBLED DE NOVO WITH A CONTIG N50 OF 52.2 KB CONTAINING AN ESTIMATED 27,148 GENES. THE RESULTS REVEALED NOVEL, INDEPENDENT WHOLE GENOME DUPLICATION.  THEY ALSO DISCOVERED CANDIDATE GENES AND OIL BIOSYNTHETIC PATHWAYS CONTRIBUTING TO HIGH OIL CONTENT. RESEQUENCING DATA IN 29 SESAME ACCESSIONS FROM 12 COUNTRIES SUGGESTED THAT THE HIGH GENETIC DIVERSITY OF LIPID-RELATED GENES MIGHT BE ASSOCIATED WITH THE WIDE VARIATION IN OIL CONTENT. ADDITIONALLY, THE RESULTS SHED LIGHT ON THE CRUCIAL STAGE OF SEED DEVELOPMENT, OIL ACCUMULATION AND POTENTIAL KEY GENES FOR SESAMIN PRODUCTION, AN IMPORTANT PHARMACOLOGICAL CONSTITUENT OF SESAME.
