RNA-seqencing of Jojoba seed tissues, seed developmental stages, and other tissues

Seeds of the desert shrub, jojoba (Simmondsia chinensis) are an abundant, renewable source of liquid wax-esters, which are valued additives in cosmetic products and industrial lubricants. Jojoba is relegated to its own taxonomic family, and there is little genetic information available to elucidate its phylogeny. Here we report the high-quality, 887 Mb, genome of jojoba assembled into 26 chromosomes with 23,490 protein-coding genes. The jojoba genome has only the whole-genome triplication (?) shared among eudicots, and no recent duplications. These genomic resources coupled with extensive transcriptome, proteome and lipidome data helped to define heterogeneous pathways and machinery for lipid synthesis and storage, provided missing evolutionary history information for this taxonomically-segregated dioecious plant species, and will support efforts to improve the agronomic properties of jojoba Overall design: RNA-sequencing of Jojoba developing seed cotyledons (n = 5), embryonic axis (n=5), seed coat (n=5), and whole developing seeds (n=5); Developmental seed time course, early stage (n=6), mid stage (n=6), late stage (n=6), and dry seed (n=6); Individual tissues for genome annotation woody stem (n=1), senescing leaf (n=1), male flowers (n=1), female flowers (n=1), developing capsule (n=1), 5 day old germinating roots (n=1), 14 day old seedling shoots (n=1), 14 day old seedling roots (n=1)
