is clinical difference between two groups and whether a cohort/patient has had a meaningful change in their FJS, respectively. The MDC90 of 12 points suggests a value lower than this may fall within measurement error. A postoperative FJS of 22 or more was predictive of achieving PASS.

In three greenhouses, the percentage of infected plants reached 100% leading to crop abandonment. Symptoms included leaf mottling and yellowing accompanied with plant stunting and apical necrosis. Extensive fruit damage was due to severe malformation and necrotic lesions on the calyx, peduncle and the endocarp (Sup. Fig. 1). To identify the causal agent, total RNA was extracted from a symptomatic eggplant fruit with PureLink™ RNA Mini Kit (ThermoFisher Scientific, USA), which was subjected to high throughput sequencing (HTS) analysis (Illumina Inc., USA). The de novo assembly of the obtained 25 million, 75 bp, single-end reads with Geneious Prime (Biomatters, New Zealand) and the annotation of the resulting contigs with BLASTn revealed the presence of only eggplant mottled crinkle virus (EMCV, genun Italy (Russo et al., 2002) and the virus is considered by the European Food Safety Authority as an exotic virus of the genera Cydonia, Malus, and Pyrus that meets all the criteria to qualify as an EU quarantine pest (Bragard et al., 2019). Τhe severity of the disease observed in Crete leading to the destruction of eggplant greenhouse cultivations, constitutes EMCV as an emerging threat to eggplant and other solanaceous crops for Greece and Europe.Ginger (Zingiber officinale Rosc.) is an important economic crop and its rhizome can be used as seasoning agent and traditional medicine in China. During July 2018 and 2019, decay symptoms occurred in the ginger planting area of Tangshan City, Hebei Province, with incidence rates of 15%～20%. The pathogen infected the rhizomes and leaves. The symptoms included leaves chlorosis and gradually wilting, even the whole plant wilted, the rhizome became soft and presented light brown maceration. In serious cases, the interior of rhizome was completely eroded, gray-white juice overflowing the epidermis, and with foul smell. The rhizome surfaces of ginger plants were disinfected with 1% NaOCl, and colonies were isolated and purified on nutrient agar (NA) solid medium by streaking. check details Eight isolates were obtained from 15 diseased tissue samples. Further morphological, physiological and biochemical identification of the pure cultured bacteria were carried out. Three strains of bacteria were picked for further analysis. All aves browned and died. The pathogenicity test was repeated 4 times and all controls were healthy. Pathogens were reisolated from symptomatic plants and rhizomes and identified as C. freundii based on the morphological, biochemical and molecular methods described previously, fulfilling Koch's hypothesis. To our knowledge, this is the first report of ginger rot caused by C. freundii in China.Taro [Colocasia esculenta (L.) Schott.] is an important root crop in the world with great economic value. In recent years, outbreaks of soft rot were observed on taro plants in several plantation areas located in Shaoguan, Guangdong Province, China (25°7'57" N, 113°19'5" E). Root tubers of taro (Paodan variety) infected by soft rot had water-soaked lesions with a dark brown-black margin including a rotten smell, they also had internal rot that was also found in root tubers with no external symptoms. In some areas, the incidence of soft rot can reach up to 30%. To isolate the causal agent, ten pieces of taro root tubers with typical symptoms were surface-sterilized with 75% ethanol and 0.1% HgCl2 solution and then washed thrice with sterile water. The tuber slices were soaked in 50 ml sterile water and shaken at 28°C, 200 rpm for 2 h, and 100 µl was streaked onto the modified Yeast Extract Beef (YEB) agar medium (1% peptone, 0.5% yeast extract, 0.5% sucrose, 0.5% NaCl, 1 Mmol/L MgSO4•7H2O, 1.5% agar, pH 7.0) ption, soft rot symptoms were observed in inoculated taro, while all control taro plants remained symptom-free. Small and pale yellow with irregular margins colonies consistent with morphological characteristics of those of D. fangzhongdai were re-isolated from symptomatic taro tubers and the housekeeping genes presence was verified by sequencing as described above, fulfilling Koch's postulates. D. fangzhongdai is a newly emerging bacterial pathogen, which causes bleeding cankers in pear trees (Tian et al. 2016), and soft rot of Phalaenopsis (Zhang et al. 2018). This is the first report of D. fangzhongdai causing soft rot disease in taro. Considering the high incidence of soft rot, this pathogen might pose a significant threat to taro and other economically important crops. Therefore, further researches are needed to investigate host range of the pathogen and develop appropriate integrated management to contain this disease spreading.The focus of this study was to develop technologies using chlorine dioxide (ClO2) gas to control postharvest stem-end rot of citrus caused by Lasiodiplodia theobromae. Mycelial growth of L. theobromae on potato dextrose agar (PDA) plugs was completely inhibited by a 24-h ClO2 exposure provided by 0.5 g of solid ClO2 generating granular mixture in a 7.7-liter sealed container. In vivo experiments were conducted on artificially inoculated 'Tango' and naturally infected 'US Early Pride' mandarins. When ClO2 treatments were initiated 0 to 6 h after inoculation, decay development was significantly reduced as compared with the control and higher ClO2 doses were more effective. A ClO2 treatment (using 3 g of generating mixture/7.7-liter sealed container) administered 0 h after inoculation resulted in 17.6% Diplodia stem-end rot incidence compared to 95.6% in the control, while the same treatment administered 24 h after inoculation was much less effective, resulting in 63.0% incidence compared to 85.4% in the control.
