关 键 词：Trichoderma harzianum plant disease resistance lateral root development plant receptors hydrophobic protein
摘 要：Trichoderma *** a beneficial fungus known for its role in enhancing root growth and improving plant resistance to diseases,thereby sustaining plant *** the interactions between Trichoderma and plants have been the subject of several studies,the specific molecular mechanisms by which it promotes lateral root development and triggers plant disease resistance still need to be fully *** the interaction between Trichoderma harzianum and tomato,significant up-regulation of the expressed gene TaHFB1(with an up-regulation of 155-fold compared to the control) was observed,which promotes tomato lateral root growth and induces disease *** expression of the TaHFB 1 protein and its application to plant roots confirmed its functions in promoting growth and inducing disease *** function validation was performed to determine its role in promoting growth and inducing disease ***-MS/MS technology was used to screen for plant receptors interacting with the hydrophobicprotein TaHFB1,and yeast two-hybrid,pull-down,and co-immunoprecipitation assays were employed to confirm the target proteins involved in plant *** co-expression techniques were used to study the molecular mechanisms and signal transduction pathways of protein-receptor *** research aims to thoroughly comprehend the regulatory mechanism of TaHFBl and provide a theoretical foundation for the development of new plant growth stimulants or immune inducers.
