Abstract

The invention provides a high-yield IAA Trichoderma viride engineering bacterial strain, and a construction method and application thereof, and belongs to the technical field of microorganisms. Encoding genes which independently encode tryptophane synthase and tryptophane decarboxylase are authenticated from the genome of the (Trichoderma viride) Tv-1511, and Trichoderma viride engineering bacteria (TvTRPS-OE, TvTDC-OE and TvTRPS / TDC-OE) subjected to TvTRPS and / or TvTDC overexpression are successfully constructed. An experiment proves that compared with an original Trichoderma spp. bacterialstrain, the IAA production capacity of the constructed three types of Trichoderma viride engineering bacteria is obviously enhanced, meanwhile, the three types of Trichoderma viride engineering bacteria have a higher stress resistance and plant growth promotion capacity, application of the Trichoderma spp. bacteria in industrial production can be accelerated, and therefore, the three types of Trichoderma viride engineering bacteria have a good practical application value.

Description

technical field

[0001] The invention belongs to the technical field of microbes, and in particular relates to a high-yield IAA engineering strain of Trichoderma viride and its construction method and application. Background technique

[0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0003] The abuse of chemical fertilizers has led to serious environmental pollution problems. The residues of pesticides and chemical fertilizers release a large amount of harmful substances to the environment, pollute soil, water and food, and pose a great threat to human health and living environment. New fertilizers that meet the sustainable development of agriculture are very necessary. There are a large number of gro...
