The road to molecular identification and detection of fungal grapevine trunk di...
Azevedo-Nogueira, Filipe; Rego, Cecilia; Gonçalves, Helena Maria Rodrigues; Fortes, Ana Margarida; Gramaje, David; Martins-Lopes, PaulaGrapevine is regarded as a highly profitable culture, being well spread worldwide and mostly directed to the wine-producing industry. Practices to maintain the vineyard in healthy conditions are tenuous and are exacerbated due to abiotic and biotic stresses, where fungal grapevine trunk diseases (GTDs) play a major role. The abolishment of chemical treatments and the intensification of several management practi...
Hormonal changes in tolerant and susceptible grapevine leaves under powdery mil...
Rute, Amaro; Diniz, Inês; Santos, Helena; Pimentel, Diana; Rego, Cecília; Mithöfer, Axel; Fortes, Ana MargaridaThe biotrophic fungus Erysiphe necator causes Powdery Mildew (PM) in grapevine. Phytohormones are major modulators of defensive responses in plants but the analysis of the hormonome associated with grapevine tolerance and susceptibility against this pathogen has not been elucidated. In this study, changes in hormonal profiling were compared between a tolerant (Vitis rupestris × riparia cv. 101-14 Millardet et d...

Plant SWEETs: from sugar transport to plant-pathogen interaction and more unexp...
Breia, Richard; Conde, Artur; Badim, Hélder; Fortes, Ana Margarida; Gerós, H.; Granell, AntonioSugars Will Eventually be Exported Transporters (SWEETs) have important roles in numerous physiological mechanisms where sugar efflux is critical, including phloem loading, nectar secretion, seed nutrient filling, among other less expected functions. They mediate low affinity and high capacity transport, and in angiosperms this family is composed by 20 paralogs on average. As SWEETs facilitate the efflux of sug...
Transcriptional, hormonal, and metabolic changes in susceptible grape berries u...
Pimentel, Diana; Amaro, Rute; Erban, Alexander; Mauri, Nuria; Soares, Flávio; Rego, Cecília; Martínez-Zapater, José M.; Mithofer, Axel; Kopka, JoachimGrapevine (Vitis vinifera) berries are extremely sensitive to infection by the biotrophic pathogen Erysiphe necator, causing powdery mildew disease with deleterious effects on grape and wine quality. The combined analysis of the transcriptome and metabolome associated with this common fungal infection has not been previously carried out in any fruit. In order to identify the molecular, hormonal, and metabolic m...
VvSWEET7 Is a Mono- and Disaccharide Transporter Up-Regulated in Response to Bo...
Breia, Richard Maykel Gonçalves; Conde, Artur Jorge Silva; Pimentel, Diana; Conde, Carlos; Fortes, Ana Margarida; Granell, Antonio; Gerós, H.The newly-identified SWEETs are high-capacity, low-affinity sugar transporters with important roles in numerous physiological mechanisms where sugar efflux is critical. SWEETs are desirable targets for manipulation by pathogens and their expression may be transcriptionally reprogrammed during infection. So far, few plant SWEET transporters have been functionally characterized, especially in grapevine. In this s...
Comparative transcriptomic response of two Pinus species to infection with the ...
Gaspar, Daniel; Trindade, Cândida; Usié, Ana; Meireles, Brigida; Fortes, Ana Margarida; Guimarães, Joana Bagoin; Simões, Fernanda; Costa, Rita LourençoPine wilt disease (PWD) caused by pine wood nematode (PWN), Bursaphelenchus xylophilus, is a serious threat to global forest populations of conifers, in particular Pinus spp. Recently, the presence of PWN was reported in dead Yunnan pine (Pinus yunnanensis) trees under natural conditions. To further understand the potential impact caused by PWN in Yunnan pine populations, a transcriptional profiling analysis wa...
