  • Recognition of the Magnaporthe oryzae effector AVR-Pia by the decoy domain of the rice NLR immune receptor RGA5

    Abstract Nucleotide-binding domain and leucine-rich repeat proteins (NLRs) are important receptors in plant immunity that allow recognition of pathogen effectors. The rice NLR RGA5 recognizes the Magnaporthe oryzae effector AVR-Pia through direct interaction. Here, we gained detailed insights into the molecular and structural bases of AVR-Pia-RGA5 interaction and the role of the RATX1 decoy ...

  • Non-chemical Pre-plant Soil Disinfestation

    The battle with pests, diseases and weeds is an everyday problem for every farmer. Due to the fact that 40% of the world’s food production is lost due to pests and diseases, farmers need to manage crop protection. An excellent example of the need for pesticides is cotton. It is a crop that is affected by various pests. Cotton farming accounts for more than 25% of all insecticides and 12% of ...

  • What is it about this soil that protects plants from devastating disease?

    Figuring out why certain soils keep plant parasites at bay could be a boon for agriculture around the globe Plants around the world are constantly under attack — often with big implications for humans. In the 1960s, millions of elm trees in Britain, France and the U.S. fell victim to Dutch elm disease, which clogs the vessels that carry life-giving water to the trees’ leaves. ...

  • Technology for life? Or technology for death?

    Mostly business people are  honest in their dealings. They work honestly with their customers. Most of the machinery manufacturers and suppliers have a tendency to make and sell bigger and bigger machines. Naturally bigger machine has bigger profit. So everybody is tempted to  sell bigger machines and bigger plants. They take satisfaction that they are working honestly. They are ...

  • Plant Sciences in Agriculture

    Plant pathogens Microorganisms, also called as microbes, live in every part of the biosphere, including soil, water, and air. Plant pathogens are the microbes that infect plants and cause diseases. In history, some plant diseases led to tremendous negative impacts on society. In 1845, potato blight disease was prevalent in all potato growing regions in Ireland. Phytophthora infestans, a ...

  • Presence and persistence of wastewater pathogen Escherichia coli O157:H7 in hydroponic reactors of treatment wetland species

    Treatment wetlands (TWs) efficiently remove many pollutants including a several log order reduction of pathogens from influent to effluent; however, there is evidence to suggest that pathogen cells are sequestered in a subsurface wetland and may remain viable months after inoculation. Escherichia coli is a common pathogen in domestic and agricultural wastewater and the O157:H7 strain causes ...

  • Detection of universal GMOs marker 35S-Promoter and tNOS-Terminator by using qTOWER 2.2, real-time PCR

    1. Introduction Due to dramatically increment of human population, many countries realized that food insufficiency will be a big issue during the next decade. To improve agriculture and livestock, they started producing genetically modified organisms (GMO) with high productivity of yield and a resistance to insects and pathogenic ...

  • Growth and accumulation of heavy metals in turnip (Brassica rapa) irrigated with different concentrations of treated municipal wastewater

    The present study has been carried out by irrigating turnip plants with different concentrations of treated municipal wastewater in order to see the effect on heavy metals accumulation and growth of plants. The turnip plants were watered with normal water and the results compared with results obtained by using treated municipal wastewater. The treatments used were: control (tap water) with 0, ...

  • The Southwest’s most important number

    By mapping a key indicator of droughts, pests and wildfire in arid places, scientists offer hope for spotting — and addressing — drought before it sets in. Junipers are hard to kill. Native to both warm, flooded tropics and the frigidly dry Arctic, it’s no surprise they come highly recommended for beginning landscapers. But in the ...

  • Bioaccumulation of triclosan and triclocarban in plants grown in soils amended with municipal dewatered biosolids

    Biosolids generally contain the microbiocidal agents triclosan (TCS) and triclocarban (TCC) that are persistent during wastewater treatment and sorp to organic material. The present study investigated the concentration of TCS in tissues of radish, carrot and soybean grown in potted soil amended with biosolids. Highest mean concentrations of TCS in radish, carrot and soybean root tissue midway ...

  • Quantitative PCR-based detection of pathogenic Leptospira in Hawai'ian coastal streams

    Pathogenic Leptospira, the causative agents of leptospirosis, are mainly associated with tropical freshwaters, but little is known about their fate in the environment. This study analyzed the distribution of pathogenic Leptospira genomes in 22 tropical coastal streams using quantitative polymerase chain reaction (qPCR). Statistical analyses were conducted to understand pathogenic ...

  • On the use of non-negative matrix factorisation to characterise wastewater from dairy processing plants

    A portable field spectrometer was used to record the time-resolved ultraviolet/visible (UV/Vis) spectrum of the effluent stream at two different dairy processing plants (a Drier Plant and Cheese Factory). The spectra exhibited significant variability. As an alternative to the partial least squares regression methods usually used in the online UV/Vis field a non-negative matrix factorisation ...

  • Using native riparian barriers to reduce Giardia in agricultural runoff to freshwater ecosystems

    Waterway degradation in agricultural settings is caused by direct and diffuse sources of pollution. Waterway fencing focuses on reducing direct faecal contamination, but the extent to which it reduces overland surface runoff of pathogens is unknown. This study evaluated the potential of four riparian treatments to reduce Giardia in saturation excess surface runoff entering the waterway. Treatment ...

  • Effect of composting on sludge contaminated with heavy metals from three different tannery streams and their bioavailability to plants

    This research was conducted to study the influence of composting on tannery sludge contaminated by Cr, Cd, Zn, Cu, and Ni. Composting of sludge streams was performed in three different piles for 60 days. The results showed that the total concentration of heavy metals was increased with composting, except in the TT-3 sample where the concentrations of Cd, Cu, and Ni did not increase. The ...
