6The Trichoderma-plant interaction is mediated by avirulence proteins produced by this fungus显示文摘The molecular basis of Trichoderma -plant interaction is very complex and still not completely understood. The colonization of the root system by rhizosphere competent strains of Trichoderma results in increased development of root/aerial systems, in improved yields and in plant disease control. Other beneficial effects, such as the induction of plant systemic resistance, have also been described. To understand the mechanisms involved we are using different approaches, including the making of transformants expressing genes that encode for compounds able to affect plant response to pathogens. Trichoderma transformants carrying the avirulence gene Avr4 from Cladosporium fulvum under the control of constitutive and inducible promoters were obtained and tested on tomato plants having the Cf4 resistance gene. Necrosis and suberification zones, similar to the symptoms appearing during Cladosporium-tomato interaction, were found when the roots of the Cf4 plants were treated with Avr4-Trichoderma. This demonstrates that selected Trichoderma strains are able to transfer to the plant molecules that may deeply affect metabolism, disease resistance etc. Therefore, these beneficial fungi can be regarded as biotechnological tools to provide a variety of crops with useful compounds. Moreover, in in vitro competition assays the transformants were found to be more effective as antagonists against Alternaria alternata than the wild type. Trichoderma sends a variety of biochemical signals to the plants including avirulence molecules; therefore the presence of avr-like proteins in the fungus proteome was investigated. Proteome analysis has permitted us to isolate and sequence many proteins potentially having this function. From the extracellular protein extracts, we have purified and sequenced a protein with structural characteristics similar to Avr4 of C. fulvum. The protein, Hytra1, was found to be a hydrophobin with chitin binding activity, the typical 8 cysteine residues, and 4 disulfide bridges. Infiltrations of the extracellular protein fractions containing Hytra1 resulted in a strong HR reaction on tobacco and tomato leaves, and induction of a novel phytoalexin.Ruocco M Lanzuise S Woo S L Ambrosino P Marra R Turrà D Gigante S Formisano E Scala F Kip N P J G M de Wit Lorito M 2004浙江大学学报(农业与生命科学版)2004,30,4:1
