Albugo Ipomoeae-panduratae
''Albugo ipomoeae-panduratae'', or white rust, is an oomycete plant pathogen, although many discussions still treat it as a fungal organism. It causes leaf and stem lesions on various ''Ipomoea ''Ipomoea'' () is the largest genus in the plant family Convolvulaceae, with over 600 species.

Oomycete
The Oomycetes (), or Oomycota, form a distinct phylogenetic lineage of fungus-like eukaryotic microorganisms within the Stramenopiles. They are filamentous and heterotrophic, and can reproduce both sexually and asexually. Sexual reproduction of an oospore is the result of contact between hyphae of male antheridia and female oogonia; these spores can overwinter and are known as resting spores. Asexual reproduction involves the formation of chlamydospores and sporangia, producing motile zoospores. Oomycetes occupy both saprophytic and pathogenic lifestyles, and include some of the most notorious pathogens of plants, causing devastating diseases such as late blight of potato and sudden oak death. One oomycete, the mycoparasite '' Pythium oligandrum'', is used for biocontrol, attacking plant pathogenic fungi. The oomycetes are also often referred to as water molds (or water moulds), although the water-preferring nature which led to that name is not true of most species, whi ...

Plant Pathogen
Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrates, or other pests that affect plant health by eating plant tissues and causing injury that may admit plant pathogens. The study of plant disease is called plant pathology. Plant pathogens Fungi Most phytopathogenic fungi are Ascomycetes or Basidiomycetes. They reproduce both sexually and asexually via the production of spores and other structures. Spores may be spread long distances by air or water, or they may be soil borne. Many soil inhabiting fungi are capable of living saprotrophically, carrying out the role of their life cycle in the soil. These are facultative saprotrophs. Fungal diseases ma ...

Fungus
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ipomoea
''Ipomoea'' () is the largest genus in the plant family Convolvulaceae, with over 600 species. It is a large and diverse group, with common names including morning glory, Ipomoea aquatica, water convolvulus or water spinach, sweet potato, bindweed, Ipomoea alba, moonflower, etc. The genus occurs throughout the tropical and subtropical regions of the world, and comprises annual plant, annual and perennial plant, perennial herbaceous plants, lianas, shrubs, and small trees; most of the species are twining Vine, climbing plants. Their most widespread common name is morning glory, but some species in related genera bear that same common name and some ''Ipomoea'' species are known by different common names. Those formerly separated in ''Calonyction'' (Ancient Greek, Greek "good" and , , , "night") are called moonflowers. The name ''Ipomoea'' is derived from the Ancient Greek , meaning , and (), meaning "resembling". It refers to their twining habit. Uses and ecology Human ...

Morning Glory
Morning glory (also written as morning-glory) is the common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose taxonomy and systematics remain in flux. These species are distributed across numerous genus, genera, including: * ''Argyreia'' * ''Astripomoea'' * ''Calystegia'' * ''Convolvulus'' * ''Ipomoea'' (the largest genus) * ''Lepistemon'' * ''Merremia'' * ''Operculina'' * ''Rivea'' * ''Stictocardia'' ''Ipomoea tricolor'', commonly known simply as "morning glory", is the archetypical species for the group and is renowned for its many beautiful varieties, such as 'Heavenly Blue', 'Flying Saucers', and 'Pearly Gates'. As the name suggests, most morning glory flowers open early in the day and begin to fade by late morning, as the Corolla (botany), corolla starts to curl inward. They thrive in full sun and prefer mesic habitat, mesic soils. While many species are known for their diurnal blooming pattern, some, such as ''Ipomoea muricata'', ''Ipo ...

Water Mould Plant Pathogens And Diseases
Water is an inorganic compound with the chemical formula . It is a transparent, tasteless, odorless, and nearly colorless chemical substance. It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food energy or organic micronutrients. Its chemical formula, , indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. In liquid form, is also called "water" at standard temperature and pressure. Because Earth's environment is relatively close to water's triple point, water exists on Earth as a solid, a liquid, and a gas. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
