Summary
Random amplified polymorphic DNA (RAPD) analysis classified new plant pathogens. This research clarifies the taxonomy of coryneform bacteria, including two novel pathovars.
Area of Science:
- Microbiology
- Plant Pathology
- Bacteriology
Context:
- Accurate bacterial taxonomy is crucial for understanding plant diseases.
- Coryneform bacteria present taxonomic challenges.
- Distinguishing between pathovars aids in disease management.
Purpose:
- To classify new plant pathogenic coryneform bacteria using Random Amplified Polymorphic DNA (RAPD) analysis.
- To investigate the genetic relatedness of novel pathovars to existing species.
- To discuss taxonomic revisions in plant pathogenic coryneform bacteria.
Summary:
- Random Amplified Polymorphic DNA (RAPD) analysis was employed to taxonomically classify plant pathogenic coryneform bacteria.
- Twenty random primers revealed significant polymorphism (80.4%) among bacterial strains.
- UPGMA cluster analysis indicated that the new pathovars, Curtobacterium flaccumfaciens pv. basellae pv. nov. and Curtobacterium flaccumfaciens pv. beticola pv. nov., are closely related to Curtobacterium flaccumfaciens.
Impact:
- Provides a molecular basis for the classification of two new bacterial pathovars.
- Supports recent taxonomic changes in plant pathogenic coryneform bacteria.
- Enhances understanding of bacterial genetic diversity and relationships in plant pathology.

The Roles of Bacteria and Fungi in Plant Nutrition
47.3K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Plant Cells and Tissues
65.6K
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

The Tree of Life - Bacteria, Archaea, Eukaryotes
38.4K
The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...

Plant Hormones
27.5K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Tonicity in Plants
59.8K
Tonicity describes the capacity of a cell to lose or gain water. It depends on the quantity of solute that does not penetrate the membrane. Tonicity delimits the magnitude and direction of osmosis and results in three possible scenarios that alter the volume of a cell: hypertonicity, hypotonicity, and isotonicity. Due to differences in structure and physiology, tonicity of plant cells is different from that of animal cells in some scenarios.
