The Role of Environmental Parameters in the Evolution of Holm Oak (Quercus ilex L. subsp. ballota (Desf.) Samp) Decline: Studies in the Iberian Peninsula

Forest Pathology, Volume 56, Issue 5, October 2026.
ABSTRACT The combination of geographical factors (climate, slope, orientation, lithology, water availability, etc.) and the pathogenicity of agents such as the oomycete from the kingdom Straminopile Phytophthora or Pythium species causes the plant disease known as oak decline in the Iberian Peninsula. Leaving aside the presence of the pathogen, the aim

Phenotypic expression of the gene‐for‐gene interaction in plant pathogenic bacteria: An implication for resistance to bacterial diseases by plants

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Plant pathogenic bacteria cause massive losses in agriculture and damage to natural plant habitats. Bacterial pathogens not only reduce crop production, but they also reduce crop quality by releasing toxins into the environment. Pathogenic bacteria that invade plant tissues must overcome the plant's defense mechanisms. Plants possess an innate

First report of jackfruit decline caused by Phytophthora spp. in Bangladesh

Fundamental and Applied Agriculture, 2020
A survey was conducted at Gazipur, one of the major jackfruit producing districts in Bangladesh where decline syndromes were frequently observed. The characteristic symptoms of jackfruit decline included trunk canker, wilting, dieback of the canopy and ...

The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1563-1566, September 2026.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

A high‐quality haplotype‐resolved genome of Pyrus calleryana provides insights into adaptive gene families

The Plant Genome, Volume 19, Issue 3, September 2026.
Abstract Callery pear (Pyrus calleryana) is a deciduous species native to East Asia with notable ornamental and ecological value, but the genomic resources for this species remain limited. Here, we report the first haplotype‐resolved, chromosome‐scale genome of P. calleryana.

Leptosphaeria maculans causing stem canker of oilseed rape in China [PDF]

, 2000
Leptosphaeria maculans occurs on oilseed rape (Brassica napus) as two types: the aggressive A-group and less damaging B-group (West et al., 1999). The disease occurs worldwide, but little is known of L. maculans from China.

Bacteriophages Control Epiphytic Pseudomonas syringae Populations in Highbush Blueberry Leaves

Microbial Biotechnology, Volume 19, Issue 9, September 2026.
The Pseudomonas syringae complex (Psc) is a group of globally distributed phytopathogens responsible for substantial agricultural losses. Here, we established a framework for the systematic identification and evaluation of bacteriophages targeting Psc strains isolated from highbush blueberries and identified candidate phages capable of suppressing ...

Diversity of Botryosphaeriaceae Species Associated With Grapevine Dieback in France: Life Traits and Aggressiveness

Plant Pathology, Volume 75, Issue 5, September‐October 2026.
This study provides a molecular and biological characterisation of Botryosphaeriaceae species found in French vineyards. It is the first substantial description of their diversity, distribution and life history traits, as well as a description of their associated virome.

Two Decades of the Immersiporthe knoxdaviesiana (Cryphonectriaceae) Canker Outbreak Driven by Clonal Pathogen Lineages

Plant Pathology, Volume 75, Issue 5, September‐October 2026.
A single clonal lineage has driven Cape beech canker for nearly two decades. However, the fungus was also found in healthy trees, suggesting that this emerging disease may have a more complex origin than a simple pathogen introduction. ABSTRACT Immersiporthe knoxdaviesiana (Cryphonectriaceae) causes an aggressive canker disease on native Myrsine ...

Effect of Botryosphaeria Stem Canker Disease on the Anatomical Structure of Eucalyptus Wood

Forest Science and Technology
Eucalyptus clones have been widely planted in Uganda to cope with the increasing demand for wood. However, the newly introduced clones are susceptible to attack by Botryosphaeria canker disease. Canker diseases have been reported to affect wood formation
