Accessing the link between subtilases and lipid signalling events in grapevine downy mildew resistance
| Resumo: | Subtilases are serine peptidases involved in several plant biological functions, however one of their most important participation is in the response to biotic and abiotic stresses. Subtilases have been linked to hormone-associated signalling, like the jasmonic acid (JA) pathway, that is particularly related with defence responses against necrotrophic fungus and herbivores. In grapevine, recent studies have implicated the JA pathway in response to Plasmopara viticola, a biotrophic oomycete. Our more recent results showed an increased expression of grapevine subtilases after P. viticola infection and JA elicitation at first hours after plant stress induction. Our aim is to deeply uncover subtilase participation in hormone-signalling pathway associated to grapevine-P. viticola interaction. |
