SPG4 Hereditary Spastic Paraplegia: From Etiology to Therapy

Movement Disorders, EarlyView.
Abstract Hereditary spastic paraplegias (HSPs) comprise a heterogeneous group of heritable neurodegenerative disorders resulting from mutations in a wide variety of genes. HSP locomotor symptoms include lower limb weakness and spasticity that arise from progressive degeneration of corticospinal axons projecting from the motor cortex to the distal ...

Comparison of Diplodia Tip Blight Pathogens in Spanish and North American Pine Ecosystems

Microorganisms, 2021
Diplodia tip blight is the most ubiquitous and abundant disease in Spanish Pinus radiata plantations. The economic losses in forest stands can be very severe because of its abundance in cones and seeds together with the low genetic diversity of the host.

Slow Dieback of Grapevine: Association of Phialophora parasitica with Slow Dieback of Grapevines

South African Journal of Enology & Viticulture, 2017
Phialophora parasitica was consistently isolated from vines showing symptoms of slow dieback and decline. Pathogenicity tests were conducted on in vitro plantlets, grafted plants in a glasshouse and on graft unions. The fungus caused discolouration of wood as well as extensive plugging of xylem tissue.

Towards quantifying uncertainty in predictions of Amazon ‘dieback’ [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2008
Simulations with the Hadley Centre general circulation model (HadCM3), including carbon cycle model and forced by a ‘business-as-usual’ emissions scenario, predict a rapid loss of Amazonian rainforest from the middle of this century onwards. The robustness of this projection to both uncertainty in physical climate drivers and the formulation of the ...

Controlled incubation, leachate, and pot assays of shrimp shell‐based compost for suppressing Verticillium dahliae in olive

Pest Management Science, EarlyView.
Shrimp shell compost suppresses Verticillium dahliae microsclerotia, enhances chitinase activity, lowers olive wilt severity and improves plant recovery under controlled conditions. Abstract BACKGROUND Verticillium wilt of olive (Olea europaea L.), caused by Verticillium dahliae Kleb., is difficult to manage because long‐lived microsclerotia persist in

Presence and abundance of airborne Botryosphaeriaceae conidia are governed by temperature and season in the Okanagan Valley, Canada

Pest Management Science, EarlyView.
Presence and abundance of Botryosphaeria dieback inoculum were determined using spore trapping and droplet digital polymerase chain reaction in British Columbia, Canada. Highest inoculum was recorded in spring (April–June) and again in summer (July–September). These results suggest early pruning in December–January can mitigate pruning wound infections.
