Silva, Marta Nunes da; Santos, Carla S.; Solla, Alejandro; Gamir, Jordi; Flors, Victor; Sampedro, Luis; Zas, Rafael; Vasconcelos, Marta W.The corresponding author name has been incorrectly swapped in the original publication. The complete correct name should read as follows. Marta Nunes da Silva In addition, the funding information has been revised. The complete correct funding information is given below. The study was performed within the ‘Characterization of the pinewood nematode/Pinus system: a phytochemical and histopatho-logical approach’ pr...
Resistance of Pinus pinea to Bursaphelenchus xylophilus explained by the dynami...
Silva, Marta Nunes da; Santos, Carla S.; Solla, Alejandro; Gamir, Jordi; Flors, Victor; Sampedro, Luis; Zas, Rafael; Vasconcelos, Marta W.Knowledge on hormonal and genetic mechanisms of pine trees in response to the pinewood nematode (PWN; Bursaphelenchus xylophilus) is limited. To describe tree defence strategies against B. xylophilus, this study used the plant stress hormone methyl jasmonate (MJ) on four pine species with different susceptibility (Pinus pinaster < P. radiata ≈ P. sylvestris < P. pinea). Three-year-old trees were sprayed with MJ...
Breeding Alnus species for resistance to Phytophthora disease in the Iberian Pe...
Cordeiro, Daniela; Pizarro, Alberto; Vélez, M. Dolores; Guevara, M. Ángeles; Marıa, Nuria de; Ramos, Paula; Cobo-Simón, Irene; Diez-Galán, AlbaAlders are widely distributed riparian trees in Europe, North Africa and Western Asia. Recently, a strong reduction of alder stands has been detected in Europe due to infection by Phytophthora species (Stramenopila kingdom). This infection causes a disease known as alder dieback, characterized by leaf yellowing, dieback of branches, increased fruit production, and bark necrosis in the collar and basal part of t...
The ADnet Bayesian belief network for alder decline: Integrating empirical data...
Gomes Marques, Inês; Vieites-Blanco, Cristina; Rodríguez-González, Patricia M.; Segurado, Pedro; Marques, Marlene; Barrento, Maria J.The globalization in plant material trading has caused the emergence of invasive pests in many ecosystems, such as the alder pathogen Phytophthora ×alni in European riparian forests. Due to the ecological importance of alder to the functioning of rivers and the increasing incidence of P. ×alni-induced alder decline, effective and accessible decision tools are required to help managers and stakeholders control t...
Phenotypic variation and genetic diversity in European Alnus species
Gomes Marques, Inês; Vieites-Blanco, Cristina; Barrento, Maria J; Semedo, José N; Rodrigues, Ana P; Scotti-Campos, Paula; Martín, M AngelaThe recent taxonomic distinction between the European common alder species Alnus glutinosa and A. lusitanica strengthens the need for studies on phenotypic and genetic variation. Understanding such variations requires the use of populations encompassing the total latitudinal distribution and environmental envelope of the distribution range of A. glutinosa and A. lusitanica. This study aims to describe the genet...
Dieback and Replacement of Riparian Trees May Impact Stream Ecosystem Functioning
Alonso, Alberto; Boyero, Luz; Solla, Alejandro; Ferreira, VerónicaAlders are nitrogen (N)-fixing riparian trees that promote leaf litter decomposition in streams through their high-nutrient leaf litter inputs. While alders are widespread across Europe, their populations are at risk due to infection by the oomycete Phytophthora ×alni, which causes alder dieback. Moreover, alder death opens a space for the establishment of an aggressive N-fixing invasive species, the black locu...
Invasive forest pathogens affect the characteristics, microbial colonisation, a...
Ferreira, Verónica; Pazianoto, Laryssa H. R.; Solla, Alejandro1. Invasive tree pathogens threaten forests worldwide, but their effects on streams are poorly understood. Nevertheless, tree infections that lead to changes in the characteristics of litter inputs to streams may affect stream communities and ecosystem processes. 2. We studied cross-ecosystem effects derived from Phytophthora cinnamomi, Phytophthora ×alni, and Ophiostoma novo-ulmi infection on Castanea sativa (...
Traumatic resin ducts induced by methyl jasmonate in Pinus spp
López‑Villamor, Adrián; Zas, Rafael; Pérez, Andrea; Cáceres, Yonatan; Silva, Marta Nunes da; Vasconcelos, Marta; Vázquez‑González, Carla; Sampedro, LuisKey message Exogenous MJ does not alter the resin duct structure of pines in the cortex, but increases the number, density and mean size of resin ducts in the secondary xylem, particularly in Pinus sylvestris and P. radiata. Abstract Methyl jasmonate (MJ) is an organic compound capable of modulating defence responses in plants. Exogenous application of MJ has been shown to modify the structure of the resin cana...
Germination and seed traits in common alder (Alnus spp.): the potential contrib...
Marques, Inês Gomes; Faria, Carla; Conceição, Sofia Isabel Rodrigues; Jansson, Roland; Corcobado, Tamara; Milanovic, Slobodan; Laurent, YannThe degradation of riparian ecosystems occurring throughout the past decades has motivated efforts aimed at the restoration of these ecosystems. The success of active revegetation approaches to restoration requires appropriate selection of reproductive material, which in turn requires knowledge of seed traits and germination. Alnus glutinosa (L.) Gaertn. (common alder) is a key riparian tree widely used in rest...
Leaf litter decomposition of sweet chestnut is affected more by oomycte infecti...
Pazianoto, Laryssa H. R.; Solla, Alejandro; Ferreira, VerónicaRiparian forests are subjected to multiple disturbances, such as tree diseases caused by invasive pathogens, whose consequences on stream functioning are unknown. We assessed the impact of Phytophthora cinnamomi infection, and interactions with temperature, on microbial decomposition of Castanea sativa leaves. Leaves from healthy, symptomatic and highly symptomatic trees were incubated in the laboratory at 13 a...
