Reaction to release treatments and distinctive attributes of butternut that promote resistance to the canker caused by Ophiognomonia clavigignenti-juglandacearum

open access: yesThe Forestry Chronicle, 2020
This research examines the impact of light and tree attributes of butternuts, including bark phenotype, on their health. Some butternuts were released by thinning the crowns of neighbouring trees in two locations in Québec, while others were not. Various

Establishing Baseline Information for the Risk of Flatheaded Borer Attack in Specialty Tree Crops Using Trapping and On‐Farm Surveys

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Flatheaded borers (Coleoptera: Buprestidae) are largely xylophagous insects. Larvae of flatheaded borers tunnel into the trunks of trees, with boring and feeding damage eventually appearing on the surface as discolored bark, sunken areas, bark splits or bark sloughing.

Tree marking guidelines for northern hardwoods: a review of criteria for assessing vigour and quality

open access: yesThe Forestry Chronicle
Recent studies have highlighted the need to update hardwood tree marking guides by changing the criteria used to assess vigour and quality, and thus the priority for deciding which trees to remove and retain during selection harvests.

MdRLKT1–MdRAX2–MdMKS1 Module Positively Regulating Resistance to Cytospora mali in Apple

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Valsa canker (caused by Cytospora mali = Valsa mali. C. mali) is one of the most destructive diseases affecting apple cultivation. The scarcity of natural germplasm resources with high resistance and immunity underscores the importance of exploring plant immune regulation factors of disease‐resistant breeding.

Macrophage centripetal migration drives spontaneous healing process after spinal cord injury. [PDF]

open access: yes, 2019
Traumatic spinal cord injury (SCI) brings numerous inflammatory cells, including macrophages, from the circulating blood to lesions, but pathophysiological impact resulting from spatiotemporal dynamics of macrophages is unknown.

Ectopic Expression of ScALDH21 From a Desert Moss Enhances Cotton Resistance to Verticillium Wilt via the Modulation of Jasmonates and Phenylpropanoid Pathways

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Biotic stresses, particularly Verticillium wilt (VW), lead to a global decline in cotton yields. Here, we demonstrate that ectopic expression of ScALDH21, a gene from the desiccation‐tolerant moss Syntrichia caninervis Mitt. and absent in angiosperms, enhances cotton's resistance to VW.

The development of diagnostic tools for the grapevine pathogen Eutypa lata : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Genetics at Massey University [PDF]

open access: yes, 2001
Eutypa lata is the causal agent of Eutypa dieback on grapevines. The fungus invades the vine and grows there unnoticed, possibly for several years, causing discolouration and deformation of the vine shoots and leaves.

Populus tremuloides seedling establishment: An underexplored vector for forest type conversion after multiple disturbances [PDF]

open access: yes, 2017
Ecosystem resilience to climate change is contingent on post-disturbance plant regeneration. Sparse gymnosperm regeneration has been documented in subalpine forests following recent wildfires and compounded disturbances, both of which are increasing.

Non‐Additive Interactions Between Multiple Mutualists and Host Plant Genotype Simultaneously Promote Increased Plant Growth and Pathogen Defence

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Understanding the impact of microbial interactions on plants is critical for maintaining healthy native ecosystems and sustainable agricultural practices. Despite the reality that genetically distinct plants host multiple microbes of large effect in the field, it remains unclear the extent to which host genotypes modulate non‐additive ...
