Transcriptome and Metabolome Reprogramming in Tomato Plants by Trichoderma Harzianum strain T22 Primes and Enhances Defense Responses Against Aphids

<strong>Figure 1</strong> Effect of <em>T. harzianum</em> T22 on aphid survival over time. Survival curves (percentage) of <em>M. euphorbiae</em> reared on the untreated water control and the <em>T. harzianum</em> T22 treated tomato plants are significantly different, <em>p</em> &lt; 0.05 (LogRank test). For the aphid longevity assay, 10 plants for each CTRL or T22 treatment were infested with 5 newly born first instar nymphs of <em>M. euphorbiae</em>. The presence of aphids and of shed exuviae, as an indicator of molting occurrence, was daily monitored. Survival curves were compared by LogRank analysis.
