| Résumé: | Copyright © 2020 Elsevier B.V. All rights reserved. miR319 family is one of the oldest and most conservative miRNA families in plant and plays an important role in plant development and abiotic stress response. In our previous study, the abundance of sly-miR319c was increased in tomatoes infected by B. cinerea, but the roles and regulatory mechanisms of sly-miR319c in B. cinerea-infected tomato remain unclear. In this study, we confirmed that miR319c was increased in tomato with B. cinerea infection. In contrast, A TCP transcript factor, TCP29, targeted by sly-miR319c was decreased in B. cinerea-infected tomato. Therefore, transgenic Arabidopsis overexpressing sly-miR319c or its target were generated for understanding the biological roles and molecular mechanism of miR319c in B.cinerea-infected plants. Results showed that miR319c overexpression improved the resistance of transgenic plants to B. cinerea, whereas TCP29 overexpression increased the susceptibility of transgenic plant to B. cinerea. So far, TCP transcription factors have been reported mainly in developmental processes. Our data indicate that TCP29 act as a negative regulator to B.cinerea infection. In conclusion, our results indicate that sly-miR319c is a positive regulator of tomato resistance to B. cinerea infection by targeting TCP29 |
