小桐子JcNF-YB3和JcNF-YB10基因的克隆與表達分析
發布時間:2018-11-02 11:42
【摘要】:以小桐子(Jatropha curcas)c DNA為模版,克隆了Jc NF-YB3和Jc NF-YB10基因的CDS序列。序列分析表明該兩個基因分別包含549和528 bp完全閱讀框(ORF),編碼182和175個氨基酸。Blast搜索結果及進化分析結果表明,Jc NF-YB3和Jc NFYB10都與油桐(Vernicia fordii)NF-YB家族基因序列一致性最高且親緣關系最近。定量分析表明,Jc NF-YB3和Jc NF-YB10在小桐子根、莖、葉、花、果皮和種子中都有表達,Jc NF-YB3在根中表達量最高,Jc NF-YB10在種子中表達量最高。兩個基因在種子發育期的表達量變化趨勢一致,但是Jc NF-YB10在種子整個生長發育期的表達量都要高于Jc NF-YB3。Jc NFYB3和Jc NF-YB10都在Na Cl、PEG、4°C低溫和ABA處理后表達量不同程度上調,推測這兩個基因在小桐子中參與抗逆反應機制和植物激素信號傳導。
[Abstract]:The CDS sequences of Jc NF-YB3 and Jc NF-YB10 genes were cloned using (Jatropha curcas) c DNA as template. Sequence analysis showed that the two genes contained 549 and 528 bp complete reading frame (ORF), encoding 182 and 175 amino acids, respectively. Blast search results and evolutionary analysis showed that, Both Jc NF-YB3 and Jc NFYB10 have the highest consistency with the (Vernicia fordii) NF-YB family of Taulownia and have the closest genetic relationship. Quantitative analysis showed that Jc NF-YB3 and Jc NF-YB10 were expressed in roots, stems, leaves, flowers, pericarp and seeds, Jc NF-YB3 was the highest in roots, and Jc NF-YB10 was the highest in seeds. The change trend of the two genes in the seed development stage was the same, but the expression of Jc NF-YB10 was higher than that of Jc NF-YB3.Jc NFYB3 and Jc NF-YB10 in the whole growth and development stage of seeds, but the expression level of Jc NF-YB10 was higher than that of Jc NF-YB3.Jc NFYB3 and Jc NF-YB10 in Na Cl,PEG,. After 4 擄C hypothermia and ABA treatment, the expression of these two genes was upregulated in varying degrees, which suggested that these two genes were involved in stress resistance response and plant hormone signal transduction in Paulownia chinensis.
