A New Threat to Limber Pine () Restoration in Alberta and Beyond: First Documentation of a Race () Virulent to Controlled Major Gene Resistance.

The coevolution of virulence reduces the effectiveness of host resistance to pathogens, posing a direct threat to forest species and their key ecosystem functions. This is a threat to limber pine (), an endangered species in Canada due to rapid decline mainly driven by white pine blister rust caused by . We present the first report of a new, virulent race of .

Transcriptional Profiling of Early Defense Response to White Pine Blister Rust Infection in (Whitebark Pine).

Pathogen perception generates the activation of signal transduction cascades to host defense. White pine blister rust (WPBR) is caused by J.C.

Genome-Wide Association Study Reveals Polygenic Architecture for Limber Pine Quantitative Disease Resistance to White Pine Blister Rust.

Development of durable resistance effective against a broad range of pathotypes is crucial for restoration of pathogen-damaged ecosystems. This study dissected the complex genetic architecture for limber pine quantitative disease resistance (QDR) to using a genome-wide association study. Eighteen-month-old seedlings were inoculated for resistance screening under controlled conditions.

The Global Forest Health Crisis: A Public-Good Social Dilemma in Need of International Collective Action.

Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss of critical ecosystem services and a global forest health crisis. We argue that the forest health crisis is a public-good social dilemma and propose a response framework that incorporates principles of collective action.
