In the strawberry nursery industry, a nursery’s reputation relies on their ability to produce disease- and insect-free plants. The best way to produce clean plants is to start with clean planting stock. Many nurseries struggle with angular leaf spot of strawberry, a serious disease that can result in severe losses either by directly damaging the plant or indirectly through a violation of quarantine standards within the industry.
The 3D structures of these large protein assemblies – the first described for any plant species – are a step towards being able to develop improved herbicides that target plant respiration. They could also aid the development of more effective pesticides, which target the pest’s metabolism while avoiding harm to crops.
Plants produce toxic substances to defend themselves against herbivores. In a new study, scientists were able to describe in detail the biosynthesis and exact mode of action of an important group of defensive substances, the diterpene glycosides, in wild tobacco plants. Diterpene glycosides allow plants to fend off herbivores. The study shows that these plant chemicals attack certain parts of the cell membrane.
The tropical plant genus Phyllanthus has been the subject of debate in the taxonomic world for years. About fifteen years ago it became clear that the genus with nearly 900 plant species, contains plants that are considered separate groups. Since previous studies had only investigated a small portion of all Phyllanthus species, this prompted to take a closer look at the entire genus.
With their expertise in microbiome research, researchers were able to demonstrate how a specific bacterium inside the seeds of rice plants effectively and in an eco-friendly way inhibits destructive plant pathogens.
Most legume species have compound leaves with multiple joined units termed leaflets, and the geometry of leaflets (the spatial structure and organization of leaflets) largely determines the compound leaf shape, which has been broadly recognized in model compound-leafed species.
Little is known about the vascular cells in leaves, in particular the phloem parenchyma. Two teams of plant researchers and bioinformatics researchers have succeeded for the first time in identifying the functions of the different cell types in the leaf vasculature of plants.
The sensory quality of watermelon fruit is determined by the content of sugar and organic acid, which determines the taste of watermelon during the development and maturation of watermelon fruit. The changes of sugar and organic acid during the watermelon fruit development were analyzed and the key gene networks controlling the metabolism of sugar and organic acid during the fruit development were identified.
A European Court ruling widely interpreted to mean that all gene-edited organisms are GMOs (Genetically Modified Organisms) may not be as prescriptive as many first assumed.
Nitrogen is one the most essential nutrients for plants. Its availability in the soil plays a major role in plant growth and development, thereby affecting agricultural productivity. Scientists were now able to show, how plants adjust their root growth to varying sources of nitrogen. In a new study they give insights in the molecular pathways of roots adaptation.
