Three bacteriophages, f20-Xaj, f29-Xaj, and f30-Xaj, with lytic activity against Xanthomonas arboricola pv. juglandis were isolated from walnut trees (VIII Bío Bío Region, Chile). These lytic bacteriophages have double-stranded DNA (dsDNA) genomes of 43,851 bp, 41,865 bp, and 44,262 bp, respectively. These are the first described bacteriophages with lytic activity against X. arboricola pv. jugl...

Improving the predictive capabilities of rainfall-runoff models in ungauged catchments is a challenging task but has important theoretical and practical significance. In this study, we investigated the predictive capabilities of the conceptual Xinanjiang model (XAJ), which is widely used for flood forecasting and simulation in China, in ungauged catchments. We further produced a hybrid rainfall...

Forty-five Xanthomonas arboricola pv. juglandis (Xaj) strains originating from Juglans regia cultivation in different countries were molecularly typed by means of MultiLocus Sequence Typing (MLST), using acnB, gapA, gyrB and rpoD gene fragments. A total of 2.5 kilobases was used to infer the phylogenetic relationship among the strains and possible recombination events. Haplotype diversity, link...

Abstract The conceptual hydrologic model has been widely used for flood forecasting, while long short-term memory (LSTM) neural network demonstrated a powerful ability to tackle time-series predictions. This study proposed novel hybrid by combining the Xinanjiang (XAJ) and LSTM (XAJ-LSTM) achieve precise multi-step-ahead forecasts. takes forecasts of XAJ as input variables enhance physical mech...

The study of runoff under the influence human activities is a research hot spot in field water science. Land-use change one main forms and it also major driver changes to process. As for relationship between land use process, yield theories pointed out that capacity spatially heterogeneous. present work hypothesizes distribution can be divided by use, which is, areas with same land-use type are...

Abstract Inflow forecast plays an indispensable role in reservoir operation. Accuracy and effectiveness of model prediction play a decisive it. In this paper, the certainty coefficient, root mean square error (RMSE), absolute deviation (MAE) Nash-Suthcliffe coefficient (NSE) are used to consider effect Soil Water Assessment Tool (SWAT) Xin'anjiang (XAJ) on inflow Jinxi Reservoir. Results indica...

Walnut blight caused by Xanthomonas arboricola pv. juglandis (Xaj) is the most important bacterial disease in walnut production worldwide. To seek biocontrol agents against Xaj, we screened 152 endophytic bacteria isolated from 87 plants. Through dual-culture method screening, obtained four antagonistic bacteria, ATE17, BME17, CIE17, and OFE17 which were Amaranthus tricolor, Bambusa multiplex, ...

Flood simulation and forecasting in various types of watersheds is a hot issue in hydrology. Conceptual hydrological models have been widely applied to flood forecasting for decades. With the development of economy, modern China faces with severe flood disasters in all types of watersheds include humid, semi-humid semi-arid and arid watersheds. However, conceptual model-based flood forecasting ...

Minimum data length is vital to guarantee accuracy in hydrological analysis. In practice, it sometimes determined by the experiences of hydrologists, leading selection acceptable minimum an arguable issue among hydrologists. Therefore, this study aims investigate impact on parameter estimation and model performance, especially for data-scarce regions. Using four primary datasets from river basi...
