Doctor X Nabat is the name of an application for the early detection of diseases and pests in horticultural crops, developed by an international team (Spain, Dubai, Egypt, Tunis, United Arab Emirates). This tool, aimed at farmers and agriculture experts, is available for devices with Android systems and computers. The tool has been tested in tomato, pepper and cucumber crops.
An international team of scientists has used neutron reflectometry techniques to understand how disease-causing pathogens damage the cell membranes of plants.
A study has conducted a comprehensive survey of nearly 200 potentially harmful alien plant species that could have a detrimental impact upon agriculture, forestry and biodiversity in Ghana once they enter the country.
Scientists observed that ergot, a common plant disease on rye, defended its host plant chemically against grass feeding insects. The ergot disease in grains spoils the yield and causes seed loss to the plant. Based on this, it is classified as harmful from the human perspective. A new study states that the ergot appears to be a beneficial protector for its host plant capable of even increasing plant fitness.
Study illustrates trade-off between plant regeneration and defense, offers strategies for enhancing regeneration in agriculture.
Scientists have found a novel way to combine two species of grass-like plant including banana, rice and wheat, using embryonic tissue from their seeds. The technique allows beneficial characteristics, such as disease resistance or stress tolerance, to be added to the plants.
A research team has discovered how a pathogenic fungus can bypass the immune system of plants. By releasing an ‘effector’ molecule, it avoids elimination at a critical stage in its reproduction cycle.
A brown blotch on a plant leaf may be a sign that the plant’s defenses are hard at work: When a plant is infected by a virus, fungus or bacterium, its immune response keeps the disease from spreading by killing the infected cell, as well as a few surrounding ones. A new study points to the evolutionary origins of this plant immune mechanism. The study may help explain how major plant defenses work and how they may one day be strengthened to increase resilience against plant diseases that each year cause billions of dollars of crop losses worldwide.
disease has emerged, threatening tomato production worldwide. This is caused by the Tomato brown rugose fruit virus (ToBRFV), a member of a devastating group of plant viruses called tobamoviruses. ToBRFV overcomes all known tobamovirus resistance in tomato, including the one conferred by Tm-22, a resistance gene responsible for the stable resistance to these viruses for more than 60 years.
During the last two decades, an accumulated body of research has been carried out to exploit the potential of using plant elicitors to enhance plant immunity. Nevertheless, while major advances have now been made, most of the inducers promoting resistance to herbivores are still at the experimental level.
