We provide a step-by-step protocol for assessing poplar resistance to stem canker pathogens using an in vivo leaf inoculation method. This method is especially suitable for large-scale assessment of Cytospora chrysosperma and Botryosphaeria dothidea canker disease resistance in poplar breeding progeny in China.

This protocol details the derivation of transplantable hematopoietic stem cells from mouse embryonic stem cells (ESC) and their subsequent injection into lethally irradiated recipient mice. Briefly, ESC are differentiated as embryoid bodies, which are then infected with retroviral HoxB4 and co-cultured with OP9 stromal cells and hematopoietic cytokines.

Here we present a protocol that facilitates the medium to high throughput functional characterization of gene and promoter constructs in tree secondary stem tissue within comparatively short time frames. It is efficient, easy to use and widely applicable to a range of tree species.
FAQs
Infection begins when pathogenic fungi or other microorganisms access stem or branch tissues through wounds or natural openings. After entry, they colonize plant tissues and establish localized damage. This entry process makes wound exposure and the condition of bark important considerations when interpreting how a canker develops and expands.
A lesion becomes especially damaging when it expands around enough of a stem or branch to girdle the structure. Girdling disrupts the movement of water and nutrients through the affected tissues, weakening growth above the damaged area. Continued disruption can produce dieback and reduce the tree’s survival prospects.
Researchers examine how the host responds to microbial colonization and how the pathogen develops within plant tissues. These host–pathogen interactions help explain why lesions progress, how damage affects transport functions, and why disease outcomes may differ among trees. Understanding these processes also supports evaluation of potentially resistant poplar material.
Assessment focuses on the location and extent of dead or damaged bark, the condition of underlying wood, lesion expansion, and associated branch or stem dieback. Changes in growth and survival provide additional evidence of impact. Tracking these features over time helps separate an isolated lesion from a progressing disease problem.
Monitoring programs examine poplar stems and branches for localized bark damage, underlying wood injury, expanding lesions, and dieback. Observers can relate these visible symptoms to changes in growth and survival to assess disease impact. Consistent symptom evaluation helps identify affected trees and supports broader assessments of forest health.
Poplar stem canker can reduce growth and survival, creating concerns for both nursery production and established forests. Disease study provides information for evaluating tree responses and selecting resistant trees. Combined with integrated management strategies, this knowledge can help reduce economic and ecological losses associated with affected poplar plantings.
