Xanthomonas gardneri; Xanthomonas perforans; Xanthomonas vesicatoria; diagnostic techniques; genes; plant pathogenic bacteria; polymerase chain reaction; tomatoes
Abstract:
... Bacterial spot of tomato is caused by Xanthomonas gardneri, X. euvesicatoria, X. perforans, and X. vesicatoria. Current diagnostic methods for the pathogens are not in-field assays. Recombinase polymerase amplification (RPA) is ideal for in-field detection assays, because it is an isothermal technique that is rapid and more tolerant to inhibitors compared with polymerase chain reaction. Hence, nov ...

biosynthesis; biotransformation; coculture; engineering; microorganisms; population dynamics
Abstract:
... The microbial production of chemicals has traditionally relied on a single engineered microbe to enable the complete bioconversion of substrate to final product. Recently, a growing fraction of research has transitioned towards employing a modular co-culture engineering strategy using multiple microbes growing together to facilitate a divide-and-conquer approach for chemical biosynthesis. Here, we ...

Abstract:
... Two complementary approaches are commonly used for analysing trophic interactions that allow inferences about consumed and assimilated resources: gut content (GCA) and stable isotope (SIA) analyses. We used these methods to assess the trophic ecology of a native (Pontastacus leptodactylus) and an invasive species (Faxonius limosus) of crayfish in the Lower Danube (Romania) by calculating five freq ...

Leaves displayed necrotic, circular, and irregular lesions. Twenty symptomatic leaves were collected in July 2017 from single (‘Amelia’ and ‘7631’) and mixed tomato cultivars in three grower fields. Necrotic lesions were also observed on the rachises, ...

Abstract:
... A simple method for vapour-phase deposition of a silane surfactant is presented, which produces tuneable homeotropic anchoring in liquid crystals. Both the zenithal anchoring energy and surface slip are measured by fitting to the latching threshold versus pulse width characteristic of a zenithal bistable nematic liquid crystal device based on a deep, submicron grating. The method is shown to give ...

Abstract:
... Bacterial spot caused by Xanthomonas perforans causes significant damage on tomato in Florida. Due to the presence of copper (Cu)-tolerant X. perforans strains, Cu bactericides are not effective in disease management. Hence, there is a critical need to find alternatives for Cu. Antibacterial activity of magnesium oxide (Nano-MgO), and other metal oxide nanoparticles, were evaluated against a Cu-to ...

Abstract:
... World production of rice exceeds 750milliontonnes per year of which a fifth is removed in the form of rice husk during the milling process. The use of rice husks as a source of sustainable and renewable energy is often hindered by lack of capital and a poor understanding of rice husk combustion characteristics. This results in the selection of poor quality technology which generates significant qu ...

Abstract:
... Mass transfer and kinetic limitations are two obstacles to the removal of a pollutant from the gas phase in a biofilter (BF) or a biotrickling filter (BTF). The issue becomes more challenging when mass transfer and kinetic limitations are present especially for treatment of pollutants in mixtures. In the present study, the most common organic pollutants which may have mass transfer or kinetic limi ...

Abstract:
... River regulation and altered land use are common anthropogenic disturbances resulting in ecological impacts through siltation or altered hydrology. We tested the separate and combined effects of increased flow and fine particles (colmation) on macroinvertebrates in flume mesocosms. We hypothesised that increased flow would reduce any effects of colmation. We tested two bed types, namely clean and ...

Abstract:
... Meloidogyne incognita is the most economically important plant‐parasitic nematode. Meloidogyne incognita manipulates plant cell development and metabolism by injecting effectors from the oesophageal glands into the plant host. Chorismate mutase (CM) is one such effector that may contribute to successful parasitism by M. incognita. This investigation identified and functionally characterized a nove ...

However, the relationship between social behavioural traits and the microbial community has received little attention. Honey bees are highly social and the workers perform different behavioural tasks in the colony that cause them to be exposed to different local environments. He ...

Abstract:
... BACKGROUND: Due to the high prevalence of EIPH in racehorses and its potential impact on the horse's health, furosemide administration is permitted up to 4‐h prior to post time in most North American racing jurisdictions. Anecdotal reports suggest that administration of furosemide 24‐h prior to strenuous exercise may be equally effective in decreasing the severity of EIPH. OBJECTIVES: To 1) compar ...
