Serine peptidases and increased amounts of soluble proteins contribute to heat priming of the plant pathogenic fungus .

causes gray mold disease in leading crop plants. The disease develops only at cool temperatures, but the fungus remains viable in warm climates and can survive periods of extreme heat. We discovered a strong heat priming effect in which the exposure of to moderately high temperatures greatly improves its ability to cope with subsequent, potentially lethal temperature conditions.

Host-specific transcriptomic pattern of Trichoderma virens during interaction with maize or tomato roots.

Background: Members of the fungal genus Trichoderma directly antagonize soil-borne fungal pathogens, and an increasing number of species are studied for their potential in biocontrol of plant pathogens in agriculture. Some species also colonize plant roots, promoting systemic resistance. The Trichoderma-root interaction is hosted by a wide range of plant species, including monocots and dicots.

PacC and pH-dependent transcriptome of the mycotrophic fungus Trichoderma virens.

Background: In fungi, environmental pH is an important signal for development, and successful host colonization depends on homeostasis. Surprisingly, little is known regarding the role of pH in fungal-fungal interactions. Species of Trichoderma grow as soil saprobes but many are primarily mycotrophic, using other fungi as hosts.

MRSP1, encoding a novel Trichoderma secreted protein, is negatively regulated by MAPK.

A novel gene, MRSP1 (MAP kinase repressed secreted protein 1) is strongly overexpressed in the tmkA MAPK mutant of the biocontrol fungus Trichoderma virens. Transcriptional regulation of MRSP1 is determined by presence or absence of TmkA, rather than by light or sporulation, making it a molecular marker for the unusual, negative, regulation by TmkA. The predicted protein is 15.
