Ceratocystis Fimbriata
''Ceratocystis fimbriata'' is a fungus and a plant pathogen, attacking such diverse plants as the sweet potato (''black rot'') and the tapping panels of the Para rubber tree (''moldy rot''). It is a diverse species that attacks a wide variety of annual and perennial plants. There are several host-specialized strains, some of which, such as '' Ceratocystis platani'' that attacks plane trees, are now described as distinct species. Taxonomy ''Ceratocystis fimbriata'', the type species of the genus '' Ceratocystis'', was originally described on the sweet potato (''Ipomoea batatus'') in 1890. It has since been found on a wide variety of annual and perennial plants. It is a large, diverse complex of species that cause wilt-type diseases of many economically important plants. There are thought to be three broad geographic clades, the North American, the Latin American and the Asian clades. It is thought likely that ''Ceratocystis fimbriata'' contains many undescribed, hidden species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Job Bicknell Ellis
Job Bicknell Ellis (January 21, 1829 – December 30, 1905) was a pioneering North American mycologist known for his study of ascomycetes, especially the grouping of fungi called the Pyrenomycetes (known today as the Sordariomycetes). Born and raised in New York, he worked as a teacher and farmer before developing an interest in mycology. He collected specimens extensively, and together with his wife, prepared 200,000 sets of dried fungal samples that were sent out to subscribers in series between 1878 and 1894. Together with colleagues William A. Kellerman and Benjamin Matlack Everhart, he founded the ''Journal of Mycology'' in 1885, forerunner to the modern journal ''Mycologia''. He described over 4000 species of fungi, and his collection of over 100,000 specimens is currently housed at the herbarium of the New York Botanical Gardens. Ellis had over 100 taxa of fungi named in his honor. Life Ellis was born in Potsdam, New York on January 21, 1829 to parents Freeman Ellis ...

Fungicide
Fungicides are biocidal chemical compounds or biological organisms used to kill parasitic fungi or their spores. A fungistatic inhibits their growth. Fungi can cause serious damage in agriculture, resulting in critical losses of yield, quality, and profit. Fungicides are used both in agriculture and to fight fungal infections in animals. Chemicals used to control oomycetes, which are not fungi, are also referred to as fungicides, as oomycetes use the same mechanisms as fungi to infect plants. Fungicides can either be contact, translaminar or systemic. Contact fungicides are not taken up into the plant tissue and protect only the plant where the spray is deposited. Translaminar fungicides redistribute the fungicide from the upper, sprayed leaf surface to the lower, unsprayed surface. Systemic fungicides are taken up and redistributed through the xylem vessels. Few fungicides move to all parts of a plant. Some are locally systemic, and some move upwardly. Most fungicides that ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus Dulcis
The almond (''Prunus amygdalus'', syn. ''Prunus dulcis'') is a species of tree native to Iran and surrounding countries, including the Levant. The almond is also the name of the edible and widely cultivated seed of this tree. Within the genus ''Prunus'', it is classified with the peach in the subgenus ''Amygdalus'', distinguished from the other subgenera by corrugations on the shell (endocarp) surrounding the seed. The fruit of the almond is a drupe, consisting of an outer hull and a hard shell with the seed, which is not a true nut. ''Shelling'' almonds refers to removing the shell to reveal the seed. Almonds are sold shelled or unshelled. Blanched almonds are shelled almonds that have been treated with hot water to soften the seedcoat, which is then removed to reveal the white embryo. Once almonds are cleaned and processed, they can be stored over time. Almonds are used in many food cuisines, often featuring prominently in desserts, such as marzipan. The almond tree prosp ...

Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have b ...

Kauai
Kauai, () anglicized as Kauai ( ), is geologically the second-oldest of the main Hawaiian Islands (after Niʻihau). With an area of 562.3 square miles (1,456.4 km2), it is the fourth-largest of these islands and the 21st largest island in the United States. Nicknamed the Garden Isle, Kauai lies 73 miles (117 km) across the Kauai Channel, northwest of Oahu. This island is the site of Waimea Canyon State Park and the Na Pali Coast State Park. The United States Census Bureau defines Kauai as census tracts 401 through 409 of Kauai County, Hawaii, which comprises all of the county except the islands of Kaʻula, Lehua and Niihau. The 2020 United States census population of the island was 73,298. The most populous town is Kapaa. Etymology and language Hawaiian narrative locates the name's origin in the legend of Hawaiiloa, the Polynesian navigator credited with discovery of the Hawaiian Islands.

Hawai'ian Language
Hawaiian (', ) is a Polynesian language of the Austronesian language family that takes its name from Hawaii, the largest island in the tropical North Pacific archipelago where it developed. Hawaiian, along with English, is an official language of the US state of Hawaii. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840. For various reasons, including territorial legislation establishing English as the official language in schools, the number of native speakers of Hawaiian gradually decreased during the period from the 1830s to the 1950s. Hawaiian was essentially displaced by English on six of seven inhabited islands. In 2001, native speakers of Hawaiian amounted to less than 0.1% of the statewide population. Linguists were unsure if Hawaiian and other endangered languages would survive. Nevertheless, from around 1949 to the present day, there has been a gradual increase in attention to and promotion of the language. Public Hawaiian-lang ...

Metrosideros Polymorpha
''Metrosideros polymorpha'', the ''ōhia lehua'', is a species of flowering evergreen tree in the myrtle family, Myrtaceae, that is endemic to the six largest islands of Hawaii. It is a highly variable tree, being tall in favorable situations, and a much smaller prostrate shrub when growing in boggy soils or directly on basalt. It produces a brilliant display of flowers, made up of a mass of stamens, which can range from fiery red to yellow. Many native Hawaiian traditions refer to the tree and the forests it forms as sacred to Pele, the volcano goddess, and to Laka, the goddess of hula. Ōhia trees grow easily on lava, and are usually the first plants to grow on new lava flows. It is a common misconception that the word ''ōhia'' is used to refer to the tree and that the word ''lehua'' refers only to its flowers. ''The Hawaiian Dictionary'' (Pukui and Elbert 1986: 199) defines ''lehua'' with these words: "The flower of the ''ōhia'' tree... ''also the tree itself'' mphas ...

Rapid ʻŌhiʻa Death
Rapid Ōhia Death (ROD) is a fungal disease that is rapidly killing forests of ōhia (''Metrosideros polymorpha'')—an ecologically important native tree species within the Hawaiian Islands that has provided a plethora of habitats for endangered birds and other species. Initially reported by landowners in Puna in 2010, ROD spread quickly across tens of thousands of acres of Ōhia trees on the Hawaiian Islands. To date, hundreds of thousands of these trees have died from this fungal disease alone. Previously healthy Ōhia trees have been observed to die within a few days to weeks, which is why the disease is known as "Rapid Ōhia Death". In April 2018, the cause of Rapid Ōhia Death was identified as two fungal species within the genus ''Ceratocystis'' which were previously unknown to science: ''Ceratocystis huliohia'' and ''Ceratocystis lukuohia''. By May 2018, infected ōhia trees were found on the island of Kauai, prompting requests that members of the public limit transpor ...
