Ips sexdentatus is expanding across southern Europe, attacking multiple Pinus species and showing the ability to colonize trees at early stages of decline. Genetic analysis of 668 individuals revealed 106 haplotypes, with Iberian populations as diversity hotspots, reflecting long‐term refugial persistence alongside more recent demographic expansion ...

Phenotypic scoring of canola blackleg severity using machine learning image analysis
Abstract Canola blackleg is a fungal disease that causes significant yield loss and plant death of infected canola (Brassica napus L., Brassica rapa L., Brassica juncea L.) fields worldwide. One of the most effective methods for controlling blackleg is through the cultivation of resistant varieties.

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

Pear Blister Canker Viroid Isolated from European Pear in Japan.
A viroid was detected from European pears cultivated in Fukushima and Yamagata prefectures, Japan. Nucleotide sequence analysis of each of the Fukushima and Yamagata isolates revealed that they were isolates of pear blister canker viroid (PBCVd) reported in France. The Fukushima isolate consisted of 312 nucleotides, whereas the Yamagata isolate had 313

Prevalence, Distribution and Identification of Phytophthora Species from Bleeding Canker on European Beech [PDF]
Abstract While bleeding canker of European beech trees (Fagus sylvatica) has long been recognized as a problem in Europe and North America, the cause in the northeastern United States has not been clear. To resolve this, we surveyed for disease prevalence on European beech, identified the pathogens involved, proved their pathogenicity, compared

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 ...
