An app for apples: Citizen-led mapping of fire blight in Central Asia

Saykal BOBUŞOVA | Tinatin DOOLOTKELDİEVA

Fire blight, caused by the bacterial pathogen Erwinia amylovora, is a severe bacterial disease of apple and pear that can quickly destroy whole plants. In the last decade, it was also detected in Central Asia, where wild pomaceous fruit plants represent the dominant species in mid-altitude forests and constitute a critical foundation for the entire ecosystem. Efficiently informing farmers, forestry services and private persons about the instances and dangers of fire blight, the correct way to recognize the symptoms, and the methods of disease control is thus of paramount importance in a vast a ...Более

The effect of leaf blight disease of rice caused by Pantoea ananatis on Nikita, Osr30 and RIRE1 retrotransposons’ movements

Yılmaz KAYA

Changing environmental conditions can cause diseases in plants, leading to novel interactions between plants and stress factors. In this respect, the relationships between pathogens and plants regarding epigenetics have still been investigated. Our aim is to examine the effect of leaf blight bacterial causal agent, Pantoea ananatis isolate PaTo34a1, on barley- and rice-specific retrotransposons’ (Nikita, Osr30 and RIRE1, respectively) movements in different rice cultivars (Oryza sativa L. cv. Tosya, Cameo, Arize, Ronaldo, Osmancik-97, Kale, Baldo, Bafra, Hakkari and Vasco) collected from diffe ...Более

First report of charcoal rot caused by Macrophomina phaseolina on kiwifruit in Turkey

İsmail ERPER

During June and August in 2018, kiwifruit (cv. Hayward) plants exhibiting symptoms of charcoal rot including chlorosis, necrosis, leaf shedding, root rot, and trunk dry rot were observed with an incidence of up 5?n three commercial orchards located in Altınordu, Fatsa and Perşembe districts of Ordu province. After surface sterilization with 1?aClO, small pieces excised from root tissues of diseased plants were rinsed twice in sterile distilled water, dried on sterile filter papers and aseptically transferred to plates containing potato dextrose agar. Ten isolates from the plates were identifie ...Более

Genetic characterization of Erwinia amylovora isolates detected in the wild walnut-fruit forest of South Kyrgyzstan

Tinatin DOOLOTKELDİEVA | Saykal BOBUŞOVA

Erwinia amylovora, the causal agent of fire blight, was first reported in Kyrgyz orchards in 2008 and, within a few years, the disease has spread throughout most of the northern part of the country. As fire blight expanded and penetrated new areas, it also reached the unique ecosystem constituted by the Arslonbob wild walnut-fruit forests in South Kyrgyzstan. Here, we present the results of field surveys in the forests and in the nearby orchards and gardens of the Jalal-Abad region during the 2019 season. Further, we use genetic profiling of the CRISPR regions to compare the genotypes of the o ...Более
