Soil, rhizosphere, and root microbiome in kiwifruit vine decline, an emerging multifactorial disease.

Kiwifruit vine decline syndrome (KVDS) is characterized by severe root system impairment, which leads to irreversible wilting of the canopy. Plants usually collapse rapidly from the appearance of the first aboveground symptoms, without recovery even in the following seasons. The syndrome has been negatively impacting kiwifruit yield in different areas of Italy, the main producing European country, since its first outbreak in 2012.

Characterization and Pathogenicity of Fungal Species Associated with Dieback of Apple Trees in Northern Italy.

Severe dieback symptoms were recently observed on apple () trees in Northern Italy, representing a growing concern for producers. Surveys were conducted over a 3-year period (2019 to 2021), and five apple orchards, from 5 to 12 years old, were monitored. A total of 33 fungal isolates isolated from symptomatic plants was selected for characterization.

Characterization of Species Involved in the Establishment and Development of Kiwifruit Vine Decline Syndrome.

Since 2012, the kiwifruit vine decline syndrome (KVDS) has progressively compromised Italian kiwifruit orchards. Different abiotic and biotic factors have been associated with the establishment and development of KVDS. During monitoring of orchards affected by KVDS in north-western Italy during 2016-2019, 71 spp.

A Quantitative Real-Time PCR Assay for Early Detection and Quantification of , an Emerging Pathogen of Apple Causing Dry Lenticel Rot.

is an emerging pathogen of apple () causing dry lenticel rot. No preventive measures have been adopted due to the lack of knowledge about the life cycle and epidemiology of this pathogen. In a preliminary survey to identify the agents of dry lenticel rot of apple, was constantly associated with the disease Using isolates from this survey, a SYBR Green quantitative PCR (qPCR) assay was developed, using calmodulin as target gene, for the detection and quantification of in apple fruit.
