Comparative Non Participating Transcriptome Analysis Response to Low Phosphorus by CmPht1;2 in Chrysanthemum

Chrysanthemum morifolium Ramat is one of the four major cut flowers in world. Pht1 family focus on uptake and transport phosphate plants. In our previous studies, CmPht1;2 overexpression line (Oe1) had higher contents both roots shoots, its root development was significantly enhanced than wild type (WT) at low phosphorus conditions chrysanthemum. Metabolomics analysis showed that several metabolites a change pyruvate metabolism tricarboxylic acid (TCA) cycle pathway. To explore gene difference expression metabolic pathway between CmPht1;2-Oe1 WT, we conducted transcriptome analysis. A total 617,681 207,271 unigenes were obtained from respectively. They classified into biological process, cellular component molecular function by Gene Ontology (GO). addition, 450 different genes (DEGs) found after 2 d treatment, 1,787 DEGs identified shoots 7 treatment under LP condition Oe1 WT. From top 20 pathways assigned Kyoto Encyclopedia Genes Genomes (KEGG), TCA mostly affected attracted attention. This research will be helpful for elucidating mechanism effects growth, stress tolerance.
