茶树细胞色素P450基因CYP710A1的克隆及差异表达特征分析
Cloning and Expression of CYP710A1 Gene of Cytochrome P450 in Camellia Sinensis
摘要
Abstract
Cytochrome P450 plays an important role in disease-resistance and insect infestation of tea plants.This study cloned the full cDNA sequence of cytochrome P450 CYP710 A1 gene of Camellia sinensis by RT-PCR and 5'/3'RACE based on the NCBI transcriptome database.The amino acid sequence, physicochemical properties, functional domain and phylogenetic tree of CYP710 A1 were determined using bioinformatics software, while the mRNA of the leaves at different positions on a plant compared applying qRT-PCR data.The results showed that the length of a complete cDNA of CYP710 A1 was 1, 911 bp encoded 502 amino acids with a molecular weight of57.06 kDa and the theoretical isoelectric point at 7.64.The gene consisted of a P450 Pfam domain with a transmembrane structure.A phylogenetic tree analysis showed that CYP710 A1 had a genetic relationship closest with Capsicum baccatumand farthest with Macleaya cordata.The qRT-PCR results indicated that the third leaves on a branch tip had the highest expression of CYP710 A1 gene, and the buds the lowest-with a 38.17-fold difference between them.关键词
