The DNA probes were

P32-labelled using Ready to go DNA labelling beads (Amersham Biosciences, Freiburg, Germany) and radioactive signals were visualized with a PhosphorImager System (Bio-Rad, Hercules, CA, USA), using QuantityOne software.

or MS basal medium alone. (XLS 442 KB) Additional file 3: Table S3. List of 257 selected Trichoderma transcripts whose probe sets afforded significant up-regulation (fold-change higher that 2.0 and FDR = 0.23) in microarray experiments after hybridization with cDNA from T. harzianum CECT 2413 grown for 9 hours in MS medium in the presence of tomato plants (MS-P) in comparison with the control condition in MS medium alone. Expression values of these probe sets obtained from the fungus grown in chitin- (MS-Ch) and glucose- (MS-G) containing MS media are also shown. (XLS 77 KB) Additional file 4: Table S4. List of 85 annotated transcript sequences of Trichoderma spp. whose probe sets showed significant up-regulation (fold-change greater than 2.0 and FDR = 0.23) in microarray very experiments after hybridization with cDNA from T. harzianum CECT 2413 grown for 9 hours in interaction with tomato plants in MS medium compared with the control

condition in MS medium alone. Biological processes (P), molecular functions (F) and cellular components (C) are based on Gene Ontology (GO) categories inferred from electronic annotation using the Blast2GO suite based on BLAST definitions.
