Description
Jute Genome Sequencing (JGS) has been initiated with an objective to first sequence and assemble the dark jute (Corchorus olitorius L., Malvaceae s. l.) genome, which has now been revalidated as a relatively small genome (~350-450 mb) amenable to high-throughput sequencing at an affordable price. Biologically jute is an excellent model system for the study of lignin biosynthesis, complex cellulose:hemicellulose interactions and xylan-type secondary cell wall (SCW) formation. Genomic insights into bast fiber biogenesis with relation to these processes are some of the long-standing research gaps between the realized and true potential of the jute crop. The basic study of lignin biosynthesis in xylan-type SCW is highly pertinent to the applied objectives of research on bioenergy, pulp, paper and renewable resources. Decoding the jute genome would contribute significantly to our understanding of cellulose, hemicellulose and lignin biosynthesis that are fundamental to natural fiber development and characteristics, especially in comparison with cotton and flax whole-genome sequences. Sequenced jute genome would foster fundamental research on genome evolution, gene expression, cell differentiation and development, cell growth and molecular determinants of plant cell wall formation. Recently, the first SNP-based linkage map was developed for dark jute using restriction-site-associated DNA (RAD) sequencing. In addition, whole transcriptome data has been generated using 454 sequencing. These genetic and transcriptomic data would aid jute genome assembly, analysis and anchoring of trait loci. Systematic analysis and characterization of jute genome would enable us to deploy novel genomic resources and tools for fiber yield, selective quality and NUE improvement, resistance to Macrophomina stem rot, and drought and herbicide tolerance.
