MicroRNA study of tomato plants triggered by Trichoderma atroviride
Tomato (Solanum lycopersicum) is one of the most important crops worldwide and a model plant to study stress responses. High-throughput RNA sequencing was used to analyze the microRNA (miRNA) profile of the aerial part of four-week-old tomato plants after application of the fungus Trichoderma atroviride to the seeds, at the transcriptional memory state. Expression changes of tomato miRNAs caused by Trichoderma are linked to plant defence responses and appear to have long-lasting effects.
