NEW YORK (GenomeWeb) – Researchers have identified two microRNAs that are down-regulated in a tomato plant that is resistant to a fungal infection, but not in a tomato plant that is susceptible to the fungus.

By comparing miRNA levels in two closely related tomato cultivars — Moneymaker, which is susceptible to the Fusarium oxysporum fungus, and Motelle, which is not — researchers led by the University of California, Riverside's Katherine Borkovitch homed in on a number of miRNA whose levels varied between the cultivars upon infection.
