小桐子JcNF-YB3和JcNF-YB10基因的克隆與表達(dá)分析
[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.
