Feruloyl esterase PCFAE2 deriving from phytophthora capsici leonian and coding gene and application of feruloyl esterase PCFAE2

Abstract

The invention discloses a feruloyl esterase PCFAE2 deriving from phytophthora capsici leonian and a coding gene and application of the feruloyl esterase PCFAE2. The feruloyl esterase PCFAE2 is protein represented by a), b) or c): a) protein composed of amino acid sequences shown at positions of 21-569 of a second sequence in a sequence list; b) protein composed of amino acid sequences shown in the second sequence in the sequence list; and c) protein which is obtained by subjecting the amino acid sequences shown in the second sequence in the sequence list or the amino acid sequences shown at the positions of 21-569 of the second sequence to substitution and / or deletion and / or addition of one or several amino acid residues, is associated to pathogenicity of the phytophthora capsici leonian and derives from the a). The feruloyl esterase PCFAE2, the coding gene and the application lay a technical foundation for further development on phytophthora capsici leonian molecule detection technique and prevention and research of various plant diseases resulting from the phytophthora capsici leonian.

Description

technical field [0001] The invention relates to a ferulic acid esterase, its encoding gene and application, in particular to ferulic acid esterase PCFAE2 from Phytophthora capsici and its encoding gene and application. Background technique [0002] Phytophthora capsici Leonian belongs to the phylum Fungi, the subphylum Flagellate, the class Oomycetes, and the order Peronomycetes. Phytophthora capsici is a pathogenic fungus with a wide range of hosts, in addition to infecting peppers, it also infects other crops. Zhou Qiming et al. reported infecting 21 species of cultivated plants and weeds in 9 families; Ren Guangchi et al. found that the fungus can harm eggplant, cucumber, tomato, cowpea, kidney bean, cabbage, cabbage, radish, carrot, peach, apricot, apple, etc. It is weakly infective to onions and garlic, and does not infect citrus and potato stems and leaves. It is the most pathogenic to pepper. [0003] Pepper blight is a soil-borne disease caused by Phytophthora cap...

AI Technical Summary

Problems solved by technology

Capsicum blight is a devastating disease with a wide distribution worldwide in the cultivation and production of peppers. The disease has a short onset period and a fast epidemic speed, which brings serious economic losses to production.
