Project description:Ammopiptanthus mongolicus is an ecologically important desert plant. To understand the role of miRNA genes in draught and cold stress adaptation, RNA-seq of small RNA in Ammopiptanthus mongolicus was performed.
Project description:Ammopiptanthus mongolicus is an ecologically important desert plant. miRNA are endogenous 20-22 nt small RNAs that play important roles in regulating gene expression in plants. To identify to the target genes of miRNA in Ammopiptanthus mongolicus, degradome sequencing was performed and a batch of transcripts were found to be targeted by miRNA. The result is helpful in understanding the roles on miRNA in plant development and environmental stress response.
Project description: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 (γ) 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
Project description:To undersand the machanism underlying the drought and cold srress tolerance of Ammopiptanthus mongolicus,we investigate the gene expression profile of Ammopiptanthus mongolicus leaves under drought stress(1hours,24hours,72hours) and low temperature (1hours,72hours ).
