Bioinformatic tools for exploring the SUMO gene network: An update
Castro, Pedro Humberto; Santos, Miguel Ângelo; Magalhães, Alexandre Papadopoulos; Tavares, R. M.; Azevedo, HerlanderPlant sumoylation research has seen significant advances in recent years, particularly since high-throughput proteomic strategies have enabled the discovery of more than one thousand SUMO targets. In the present chapter, we update the previously reported SUMO (small ubiquitin-related modifier) gene network (SGN) to its v4 iteration. SGN is a curated assembly of Arabidopsis thaliana genes that have been function...
SUMO E3 ligase SIZ1 connects sumoylation and reactive oxygen species homeostasi...
Castro, Pedro Humberto; Couto, Daniel; Santos, Miguel Angelo; Freitas, Sara; Lourenco, Tiago; Dias, Eva; Huguet, Stephanie; da Silva, Jorge MarquesThe ubiquitin-like modifying peptide SMALL UBIQUITIN-LIKE MODIFIER (SUMO) has become a known modulator of the plant response to multiple environmental stimuli. A common feature of many of these external stresses is the production of reactive oxygen species (ROS). Taking into account that SUMO conjugates rapidly accumulate in response to an external oxidative stimulus, it is likely that ROS and sumoylation conve...
Phylogenetic analysis and genetic diversity of the xylariaceous ascomycete Bisc...
Costa, Daniela; Ramos, Vitor; Tavares, R. M.; Baptista, Paula; Lino-Neto, T.Cork oak is a tree species with ecological importance that contributes to economic and social development in the Mediterranean region. Cork oak decline is a major concern for forest sustainability and has negative impacts on cork oak growth and production. This event has been increasingly reported in the last decades and seems to be related with climate changes. Biscogniauxia mediterranea is an endophytic fungu...
Olive fungal epiphytic communities are affected by their maturation stage
Castro, Joana; Costa, Daniela; Tavares, R. M.; Baptista, Paula; Lino-Neto, T.The phyllosphere comprises the aerial parts of plants and is colonized by a great diversity of microorganisms, either growing inside (as endophytes) or on the surface (as epiphytes) of plant tissues. The factors that structure the diversity of epiphytes and the importance of these microorganisms for host plant protection have been less studied when compared to the case of endophytes. In this work, the epiphytic...
The influence of bioclimate on soil microbial communities of cork oak
Costa, Daniela; Tavares, R. M.; Baptista, Paula Daniela Pereira; Lino-Neto, T.Background Soil microbiomes are important to maintain soil processes in forests and confer protection to plants against abiotic and biotic stresses. These microbiomes can be affected by environmental changes. In this work, soil microbial communities from different cork oak Portuguese forests under different edaphoclimatic conditions were described by using a metabarcoding strategy targeting ITS2 and 16S barcode...
Bacteria could help ectomycorrhizae establishment under climate variations
Reis, Francisca; Magalhães, Alexandre P; Tavares, R. M.; Baptista, Paula; Lino-Neto, T.Rhizosphere microbiome is one of the main sources of plant protection against drought. Beneficial symbiotic microorganisms, such as ectomycorrhizal fungi (ECMF) and mycorrhiza helper bacteria (MHB), interact with each other for increasing or maintaining host plant fitness. This mutual support benefits all three partners and comprises a natural system for drought acclimation in plants. Cork oak (Quercus suber L....
Illuminating Olea europaea L. endophyte fungal community
Costa, Daniela; Fernandes, Telma; Martins, Fatima; Pereira, Jose A.; Tavares, R. M.; Santos, P. M.; Baptista, Paula; Lino-Neto, T.A wide array of fungal endophytes is known to inhabit plant tissues and were recently recognized as essential for plant health. A better description of the scarcely known endophyte microbiota in olive tree phyllosphere is the first step for elucidating the microbial interactions that lead to olive disease establishment. In this work, the fungal endophytic community of the phyllosphere of different olive tree cu...
Cork oak forests soil bacteria: potential for sustainable agroforest production
Reis, Francisca Rodrigues; Pereira, Ana João; Tavares, R. M.; Baptista, Paula; Lino-Neto, T.Plant growth promoting rhizobacteria (PGPR) are in increasing demand due to their role in promoting sustainable practices, not only in agriculture but also in forestry. Keeping in mind the future application of PGPR for increasing cork oak sustainability, the aim of this study was to find cork oak PGPR isolates with increased nutrient solubilisation traits, able to promote root morphological changes and/or anta...
In vitro interactions between the ectomycorrhizal Pisolithus tinctorius and the...
Baptista, Paula; de Pinho, Paula Guedes; Moreira, Nathalie; Malheiro, Ricardo; Reis, Francisca; Padrão, Jorge; Tavares, R. M.; Lino-Neto, T.Ectomycorrhizal fungi are crucial for forests sustainability. For Castanea sativa, ectomycorrhizal fungus Pisolithus tinctorius is an important mutualist partner. Saprotrophic fungi Hypholoma fasciculare, although used for biocontrol of Armillaria root disease, it negatively affected the interaction between the P. tinctorius and plant host roots, by compromise the formation of P. tinctorius-C. sativa mycorrhiza...
Cork oak endophytic fungi as potential biocontrol agents against biscogniauxia ...
Costa, Daniela; Tavares, R. M.; Baptista, Paula; Lino-Neto, T.An increase in cork oak diseases caused by <i>Biscogniauxia mediterranea</i> and <i>Diplodia corticola</i> has been reported in the last decade. Due to the high socio-economic and ecologic importance of this plant species in the Mediterranean Basin, the search for preventive or treatment measures to control these diseases is an urgent need. Fungal endophytes were recovered from cork oak trees with different dis...
