Transcriptome Analysis of LBD Genes in Potato

To explore the potential role of StLBD in growth and development, the transcriptome data of 16 tissues was downloaded from PGSC (http://solanaceae.plantbiology.msu.edu/index.shtml): flower, petiole, root, shoot apex, stamen, stem, stolon, tuber cortex, tuber peel, tuber pith, tuber sprout, leaf tuber (mature), tuber (young), and whole plant. An analysis of transcriptome data to the expression level (β-aminobutyric acid, methyl benzophenazole thioacetate, Phytophthora infestans, sodium chloride, mannitol, heat stress, abscisic acid, gibberellin, 6-benzylaminopurine, and auxin) of 10 stress treatments was conducted. Fragments per kilobase million (FPKM) values of each LBD gene were calculated, which indicated that their differentially expressed genes were identified. An expression heatmap of different tissues and different treatments of the LBD family was drawn by HemI.
