Puccinia Menthae
''Puccinia menthae'' is a fungal plant pathogen that causes rust on mint plants. Hosts and symptoms ''Puccinia menthae'' feeds on plants in the family Lamiaceae. Commonly there are two groups of mint rust, spearmint rust and peppermint rust. The strain of ''P. menthae'' that infects peppermint is not able to infect spearmint plants and the strain that infects spearmint cannot infect peppermint, but both can infect Scotch spearmint.University of Illinois Extension – Department of Crop Sciences. Report on Plant Disease, Mint Rust. 2016. In a study done by Stiles et al., it was found that a ''P. menthae'' isolate found on oregano could infect oregano, Greek oregano, and sweet marjoram but could not infect spearmint species. Stiles obtained another rust isolate from spearmint and found it did not infect oregano or related species. This suggests the strains of ''P. menthae'' are host specific within the plant family Lamiaceae. More research is required to determine more information ...

Plant Pathogen
Plant pathology (also phytopathology) is the scientific study of 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, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rust (fungus)
Rusts are plant diseases caused by pathogenic fungi of the order Pucciniales (previously known as Uredinales). An estimated 168 rust genera and approximately 7,000 species, more than half of which belong to the genus ''Puccinia'', are currently accepted. Rust fungi are highly specialized plant pathogens with several unique features. Taken as a group, rust fungi are diverse and affect many kinds of plants. However, each species has a very narrow range of hosts and cannot be transmitted to non-host plants. In addition, most rust fungi cannot be grown easily in pure culture. A single species of rust fungi may be able to infect two different plant hosts in different stages of its life cycle, and may produce up to five morphologically and cytologically distinct spore-producing structures viz., spermogonia, aecia, uredinia, telia, and basidia in successive stages of reproduction. Each spore type is very host specific, and can typically infect only one kind of plant. Rust fungi are o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mentha
''Mentha'' (also known as mint, from Greek , Linear B ''mi-ta'') is a genus of plants in the family Lamiaceae (mint family). The exact distinction between species is unclear; it is estimated that 13 to 24 species exist. Hybridization occurs naturally where some species' ranges overlap. Many hybrids and cultivars are known. The genus has a subcosmopolitan distribution across Europe, Africa - (Southern Africa), Asia, Australia - Oceania, North America and South America. Its species can be found in many environments, but most grow best in wet environments and moist soils. Description Mints are aromatic, almost exclusively perennial herbs. They have wide-spreading underground and overground stolons and erect, square, branched stems. Mints will grow 10–120 cm (4–48 inches) tall and can spread over an indeterminate area. Due to their tendency to spread unchecked, some mints are considered invasive. The leaves are arranged in opposite pairs, from oblong to lanceol ...

List Of Puccinia Species
This is an incomplete list of species in the fungal genus ''Puccinia''. Members of this genus are pathogens on all major cereal crop species except rice, and some cause large economic losses.

Fungal Plant Pathogens And Diseases
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, 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 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 organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Puccinia
''Puccinia'' is a genus of fungi. All species in this genus are obligate plant pathogens and are known as rusts. The genus contains about 4000 species. The genus name of ''Puccinia'' is in honour of Tommaso Puccini (died 1735), who was an Italian doctor and botanist who taught Anatomy at Hospital of Santa Maria Nuova in Florence. The genus was circumscribed by Pier Antonio Micheli in Nov. Pl. Gen. on page 213 in 1729. Taxonomy Examples of ''Puccinia'' rusts and the diseases they cause: * '' Puccinia asparagi'' - Asparagus rust * ''Puccinia graminis'' - Stem rust, also known as black rust * '' Puccinia horiana'' - Chrysanthemum white rust * '' Puccinia mariae-wilsoniae'' - Spring beauty rust * '' Puccinia poarum'' - Coltsfoot rust gall * ''Puccinia psidii'' - Guava rust or eucalyptus rust * '' Puccinia recondita'' - Brown rust * ''Puccinia sessilis'' - Arum rust and Ransoms rust * '' Puccinia striiformis'' - Stripe rust, also known as yellow rust * ''Puccinia triticina'' - Wh ...
