Abstract

Successful biocontrol interactions often require that the beneficial microbes involved are resistant or tolerant to a variety of toxicants, including antibiotics produced by themselves or phytopathogens, plant antimicrobial compounds, and synthetic chemicals or contaminants. The ability of Trichoderma spp., the most widely applied biocontrol fungi, to withstand different chemical stresses, including those associated with mycoparasitism, is well known. In this work, we identified an ATP-binding cassette transporter cell membrane pump as an important component of the above indicated resistance mechanisms that appears to be supported by an extensive and powerful cell detoxification system. The encoding gene, named Taabc2, was cloned from a strain of Trichoderma atroviride and characterized. Its expression was found to be upregulated in the presence of pathogen-secreted metabolites, specific mycotoxins and some fungicides, and in conditions that stimulate the production in Trichoderma spp. of antagonism-related factors (toxins and enzymes). The key role of this gene in antagonism and biocontrol was demonstrated by the characterization of the obtained deletion mutants. They suffered an increased susceptibility to inhibitory compounds either secreted by pathogenic fungi or possibly produced by the biocontrol microbe itself and lost, partially or entirely, the ability to protect tomato plants from Pythium ultimum and Rhizoctonia solani attack.

Abstract

Summary Protease inhibitors (PIs) are small ubiquitous proteins with a variety of biological functions in plants, including protein stabilization, modulation of apoptosis and defense against pathogens. Kunitz-like inhibitors (PKPIs) and proteinase inhibitors 1 ( PI -1) are abundant in storage organs of potato plants and are up-regulated in other tissues in response to biotic and abiotic stress. However, little information is available on genotype-dependent regulation of individual PKPI group- and PI- 1 genes. We isolated, sequenced and characterized four novel full-length PI -1 cDNAs ( PPI 3 A 2, PPI 3 A 4, PPI 2 C 4 and PPI 2 C 1 A ) from Solanum tuberosum cv. Desiree. Specific primers were developed for PI- 1 genes PPI 3 A 2, PPI 3 B 2 and PPI 2 C 4 and the three PKPI homology groups A, B and C. Their expression profiles were studied by semi-quantitative RT-PCR in comparison with transcripts of the PI- 1, Pin 2 and PR 1 gene families in various tissues, after wounding and Globodera rostochiensis infection of nematode-resistant genotypes P40 and LB7/4/c-I-7, and susceptible cv. Desiree. Individual PI- 1 genes and PKPI homology groups were expressed in a tissue- and genotype-dependent manner after wounding and nematode infection. The differences in PI expression patterns were related to the intensity, type of inhibitors produced, and the kinetics of induction. Therefore, different genotype–environment combinations produce different sets of PI transcripts. Potato plants reacted to G. rostochiensis infection by modulating PKPI , PI- 1 and Pin 2, but not PR 1 gene expression, suggesting that the jasmonic acid but not the salicylic acid defense signaling pathway is activated. PI expression profiles were not correlated with the resistance status of the potato genotype infected with G. rostochiensis .

Abstract

Trichoderma harzianum T22 is one of the Trichoderma isolates most used as active ingredient in commercial bio-fungicides and bio-fertilizers. In addition to their mycoparasitic abilities, many Trichoderma strains can colonize and grow in association with plant roots and can significantly increase plant growth, development and systemic resistance to pathogen attack. During Trichoderma–plant interaction, a plant response has been confirmed as responsible for at least part of the protection effect, but the molecular mechanisms involved are still largely unknown. The protein Hytra1 secreted by Trichoderma was tested for its ability to induce a hypersensitive reaction (HR) and induced systemic resistance in tomato plants. Hytra1 infiltration elicited a strong HR on tomato leaves and could trigger plant defence reactions subsequent to pathogen infections both locally and systemically. Physiological analyses of tomato leaves treated with Hytra1 showed that this hydrophobin can induce an oxidative burst in plant cells. Low Hytra1 concentrations also triggered activation of the antioxidant system that controls accumulation of reactive oxygen species (superoxide anions and peroxides). This modulation plays a role in transduction of the oxidative signal, leading to formation of signal molecules (lipoperoxides) that trigger the accumulation of defence molecules (e.g. riscitin) and PR proteins. Real-time PCR analysis of RNA extracted from tomato plants 24 hours after treatment with 0.31 micron Hytra1 showed strong activation of PR4 transcription, while PR1 expression was induced to a lesser extent in the same conditions. Steady-state mRNA levels of PR4 and PR1 were about 13-fold and 5-fold higher, respectively, than in controls.
