Pinewood nematode-associated bacteria contribute to oxidative stress resistance...
Vicente, Claudia; Ikuyo, Yoriko; Mota, Manuel; Hasegawa, KoichiBackground: Pine wilt disease (PWD) caused by the pinewood nematode Bursaphelenchus xylophilus is one of the most serious forest diseases in the world. The role of B. xylophilus-associated bacteria in PWD and their interaction with the nematode, have recently been under substantial investigation. Several studies report a potential contribution of the bacteria for the PWD development, either as a helper to enhan...
Evidence for the involvement of ACC deaminase from Pseudomonas putida UW4 in th...
Nascimento, Francisco; Vicente, Claudia; Barbosa, Pedro; Espada, Margarida; Glick, B; Mota, Manuel; Oliveira, SolangeAbstract Pine wilt disease, caused by the nematode Bursaphelenchus xylophilus, is responsible for devastation of pine forests worldwide. Until now, there are no effective ways of dealing with this serious threat. The use of 1-aminocyclopropane-1-carboxylate (ACC) deaminase (encoded by the acdS gene)-producing plant growth-promoting bacteria has been shown to be a useful strategy to reduce the damage due to biot...
Characterization of bacterial communities associated with the pine sawyer beetl...
Vicente, Claudia; Nascimento, Francisco; Espada, Margarida; Barbosa, Pedro; Hasegawa, Koichi; Mota, Manuel; Oliveira, SolangePine wilt disease (PWD) has a tremendous impact on worldwide forestlands, both from the environmental and economical viewpoints. Monochamus sp., a xylophagous insect from the Cerambycidae family, plays an important role in dissemination of the pinewood nematode, Bursaphelenchus xylophilus, the primary pathogenic agent of PWD. This study investigates, for the first time, the bacterial communities of Monochamus g...
Characterization of Bacteria Associated with Pinewood Nematode Bursaphelenchus ...
Vicente, Claudia S. L.; Nascimento, Francisco; Espada, Margarida; Barbosa, Pedro; Mota, Manuel; Glick, Bernard R.; Oliveira, SolangePine wilt disease (PWD) is a complex disease integrating three major agents: the pathogenic agent, the pinewood nematode Bursaphelenchus xylophilus; the insect-vector Monochamus spp.; and the host pine tree, Pinus sp. Since the early 80's, the notion that another pathogenic agent, namely bacteria, may play a role in PWD has been gaining traction, however the role of bacteria in PWD is still unknown. The present...
Perspectives on the use of plant growth promoting bacteria as biocontrol agents...
Nascimento, Francisco; Vicente, Claudia; Espada, Margarida; Mota, ManuelPine Wilt Disease (PWD) has been considered one of the major threats affecting conifer forests and forestry economics throughout the whole world. This complex disease is caused by the pinewood nematode (PWN) Bursaphelenchus xylophilus, through an intricate interaction with other partners like nematode associated bacteria and an insect vector that is responsible for nematode tree-to-tree transportation and disse...
Heterogeneous microbial community associated with Bursaphelenchus xylophilus
Vicente, Claudia; Nascimento, Francisco; Espada, Margarida; Barbosa, Pedro; Mota, Manuel; Glick, B; Oliveira, SolangePine wilt disease (PWD) is a complex disease integrating three major factors: the causal agent, the pinewood nematode Bursaphelenchus xylophilus; the insect-vector Monochamus spp.; and the host pine tree, Pinus sp. Since the early 80’s, the notion that another pathogenic agent involved, namely bacteria, may play a role in PWD has been gaining traction, however the role of bacteria in PWD is still unknown. The p...
Pine wilt disease and red ring disease of coconut: opportunities and perspectiv...
Mota, Manuel; Souza, Ricardo; Vieira, Paulo; Espada, Margarida; Nascimento, Francisco; Vicente, ClaudiaThe xylophagous nematodes Bursaphelenchus cocophilus and B. xylophilus (Nematoda: Parasitaphelenchidae), are causative agents of two serious diseases, “red ring disease” (RRD) with great importance to coconut and certain oil palm species in Central and South America, and in “pine wilt disease” (PWD), which has wreaked havoc in forest areas in the Far East and now more recently in Europe (Portugal and Spain). PW...
The use of the ACC deaminase producing bacterium Pseudomonas putida UW4 as a bi...
Nascimento, Francisco; Vicente, Claudia; Espada, Margarida; Bernard; Glick, R; Mota, Manuel; Oliveira, SolangePine wilt disease, caused by the nematode Bursaphelenchus xylophilus, is responsible for the devastation of worldwide pine forestlands. Until today, the only effective solution to this serious threat resides on the destruction of infected trees, which is both economic and ecologically unacceptable. The use of ACC deaminase-producing plant growth promoting bacteria has been shown to be a useful strategy in order...

Until now, there are no effective ways of dealing with this serious threat. The use of ACC deaminase-producing plant growth promoting bacteria has been shown to be a useful strategy to reduce the damage due to biotic and abiotic stresses. Pinus pinaster seedlings inoculated with the AC...
