First Report of Causing Common Scab on Potato in China.

Severe typical deep-pitted lesions of Potato Common Scab (PCS) disease were observed in two locations in China, Dingxi, Gansu Province, and Shuozhou, Shaanxi Province, in 2021. Potato farms in Dingxi growing cultivar Huangxin 226 (26 hectares) exhibited a scab disease incidence of 10%, while cultivar Jinshu 15# (4 hectares) in Shuozhou showed a disease incidence of 30% (Fig. 1).

Comparative genomic and transcriptome analyses of two strains revealed distinct virulence determinants and phenotypic features.

Potato soft rot caused by spp. are devastating diseases of potato which cause severe economic losses worldwide. is considered as one of the most virulent species.

Isolation, characterization and application of noble bacteriophages targeting potato common scab pathogen Streptomyces stelliscabiei.

Bacteriophages have emerged as promising alternatives to pesticides for controlling bacterial pathogens in crops. Among these pathogens, Streptomyces stelliscabiei (syn. S.

Species Diversity of spp. Causing Potato Aerial Stem Rot in China.

spp. are the primary causative agents of aerial stem rot in potatoes in China. A nationwide survey revealed the widespread occurrence of aerial stem rot in the northern, southern, and southwestern cultivation regions, with occurrence rates ranging from 1 to 60%.

First Report of Causing Potato Common Scab in Guizhou Province, China.

Potato ( L.) common scab can be caused by multiple pathogenic spp. worldwide.

First Report of Causing Blackleg on Potato in Inner Mongolia, China.

Blackleg on potato plants () is caused by spp. and spp. (Charkowski, 2018) worldwide.

Infection of Citrus Leaves and Host Defense Activation Compared to Root Infection.

Currently, little is known about the host pathogen interaction between spp. and citrus roots versus leaves. Therefore, we compared the molecular events occurring in citrus roots and leaves after zoospore inoculation with .

Characterization of Antimicrobial-Producing Beneficial Bacteria Isolated from Huanglongbing Escape Citrus Trees.

The microbiome associated with crop plants has a strong impact on their health and productivity. Liberibacter asiaticus (Las), the bacterial pathogen responsible for Huanglongbing (HLB) disease, lives inside the phloem of citrus plants including the root system. It has been suggested that Las negatively affects citrus microbiome.
