草地早熟禾葉綠素酶1基因PpCHL1的克隆和表達(dá)分析
[Abstract]:The full-length cDNA sequence of chlorophyll enzyme 1 gene (PpCHL1) was cloned from Kentucky bluegrass by race technique for the first time. The cDNA sequence was submitted to GenBank, the accession number was KU145126, and the open reading frame was 951 BP, encoding 361 amino acids. Isoelectric point 6.11, average hydrophilic index 0.084, belong to hydrophobic acid protein. The advanced structure analysis showed that it had the conserved domain of lipase family and the functional activity site of hydrolase. The expression of POA in roots, stems and leaves of Kentucky bluegrass and three plant growth regulators, abscisic acid (ABA), salicylic acid (SA) and methyl jasmonate (Meja), was analyzed by real-time fluorescence quantitative PCR. The results showed that the expression of PpCHL1 gene in different tissues of Kentucky bluegrass was significantly different, and the highest expression level of PpCHL1 gene was found in the leaves, which was induced by ABANASA and Meja.
