Indication of Quantitative Multiple Disease Resistance to Foliar Pathogens in Pinus radiata D.Don in New Zealand [PDF]

Frontiers in Plant Science, 2020
Increasing resistance against foliar diseases is an important goal in the Pinus radiata D.Don breeding program in New Zealand, and screening for resistance has been in place for some time, since the late 1960s.

Advancing forest pathology: the need for community-driven molecular experimental model systems. [PDF]

New Phytol
Summary Forests world‐wide are under escalating threat from emerging and invasive fungal and oomycete pathogens, driven by globalization and shifting climate dynamics. Effective strategies to manage the current scale and rate of changes in forest health remain hindered by our limited ability to study the underlying mechanisms of pathogen–host and ...

A novel GFP-based approach for screening biocontrol microorganisms in vitro against Dothistroma septosporum

Journal of Microbiological Methods, 2011
Dothistroma septosporum is the causal agent of Dothistroma needle blight of pine trees. A novel green fluorescent protein (GFP)-based screening method was developed to assess the potential of microorganisms for biocontrol of Dothistroma. The screen utilizes GFP expression as an indicator of metabolic activity in the pathogen and hygromycin resistance ...

Light Limitation and Foliar Pathogenic Infection Impact Phloem Anatomy and Function in Pinus radiata D. Don. [PDF]

Plant Cell Environ
ABSTRACT Phloem plays a major role in plant physiology, health and growth. However, little research has addressed the impact of biotic and abiotic stressors on phloem structure and development. This study extends recent interest on stress impact on phloem to further understand its physiological limits by exploring a common combination of stressors ...

Silent invaders: the hidden threat of asymptomatic phytobiomes to forest biosecurity. [PDF]

New Phytol
Summary Populations of diverse, unknown, and potentially pathogenic fungi and fungus‐like organisms are continuously introduced into new locations via asymptomatic infections (e.g. as endophytes or latent pathogens) within internationally traded live plants.

Effect of trait’s expression level on single-step genomic evaluation of resistance to Dothistroma needle blight [PDF]

BMC Plant Biology, 2020
Background Many conifer breeding programs are paying increasing attention to breeding for resistance to needle disease due to the increasing importance of climate change.

Histological Analysis of Dothistroma septosporum Infection on Different Provenances of Pinus sylvestris

Forests
Dothistroma needle blight (DNB) is one of the most significant diseases of conifers, causing premature defoliation, growth reduction, and, in extreme cases, mortality. Histological analysis was undertaken on inoculated seedlings of three different seed sources of Pinus sylvestris L.

A fragmented aflatoxin-like gene cluster in the forest pathogen Dothistroma septosporum

Fungal Genetics and Biology, 2007
The polyketide toxin dothistromin is very similar in structure to the aflatoxin precursor, versicolorin B. Dothistromin is made by a pine needle pathogen, Dothistroma septosporum, both in culture and in planta. Orthologs of aflatoxin biosynthetic genes have been identified that are required for dothistromin biosynthesis in D. septosporum.

Substantial heritable variation for susceptibility to Dothistroma septosporum within populations of native British Scots pine (Pinus sylvestris). [PDF]

Plant Pathol, 2016
The threat from pests and pathogens to native and commercially planted forest trees is unprecedented and expected to increase under climate change. The degree to which forests respond to threats from pathogens depends on their adaptive capacity, which is
