Abstract

Trichoderma harzianum T6776 is a promising beneficial isolate whose effects consist of growth promotion, positive response of photosynthetic activity, hormonal signaling, and carbon partitioning in tomato, coupled with biocontrol of plant pathogens. Here, we present the first genome assembly of T6776, providing a useful platform for the scientific community.

Highlights

  • Trichoderma harzianum strain T6776 was isolated by the authors from soil in Tuscany, Italy, and it has been studied for many years as a bioactive principle in biostimulants and biopesticides

  • The first evidence of its beneficial effects in terms of growth promotion and biocontrol activity against fungal plant pathogens of high economic impact was demonstrated on different tomato cultivars and against Rhizoctonia solani, Fusarium oxysporum f. sp. lycopersici, and F. oxysporum f. sp. radicis-lycopersici (4)

  • These results encouraged us to produce a complete sequence of T. harzianum T6776 as an efficient and powerful tool to investigate the molecular mechanisms controlling the interaction between the fungus and the tomato plant

Summary

Introduction

Trichoderma harzianum strain T6776 was isolated by the authors from soil in Tuscany, Italy, and it has been studied for many years as a bioactive principle in biostimulants and biopesticides. Trichoderma species are well-known beneficial fungi used as biocontrol agents. The capacity to produce antibiotics and enzymes, to induce systemic resistance in plants, and to parasitize phytopathogenic fungi, coupled with a high metabolic versatility and a strong competition ability, make many Trichoderma isolates useful microorganisms for commercial biofertilizers and biopesticides (1–3).
