Transcriptomic Determination of the Core Genes Regulating the Growth and Physiological Traits of Quercus mongolica Fisch. ex Ledeb

Quercus mongolica is a multipurpose forest species of high economic value that also plays an important role in the maintenance and protection its environment. Consistent with wide geographical distribution Q. mongolica, differences growth physiological traits populations different provenances have been identified. In this study, molecular basis for these was investigated by examining growth, traits, gene expression seedlings from six northern China. The results showed there were significant except ground diameter (p < 0.05), identified abscisic acid (ABA), indole-3-acetic (IAA), soluble sugar contents as distinguish provenances. transcriptome analysis largest difference total number differentially expressed genes (DEGs) between trees Jilin Shandong (6918), smallest Heilongjiang Liaoning (1325). DEGs concentrated mainly Gene Ontology entries metabolic process, catalytic activity, cell, Kyoto Encyclopedia Genes Genomes pathways carbohydrate metabolism, biosynthesis other secondary metabolites, signal transduction, environmental adaptation. These assignments indicated adapt to changes climate environment regulating physiological, biochemical, processes. A weighted co-expression network revealed highly correlations darkmagenta, grey60, turquoise, plum1 modules ABA content, IAA protein respectively. key roles related stress response (SDH, WAK5, APA1), processes (UGT76A2, HTH, At5g42100, PEX11C), transduction (INPS1, HSD1), chloroplast (CAB13, PTAC16, PNSB5). Functional annotation core implies can environments photosynthesis, plant hormone response, biochemical Our provide insight into adaptability plants environments.
