Ascospore
An ascus (; ) is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or species can occur in numbers of one (e.g. ''Monosporascus cannonballus''), two, four, or multiples of four. In a few cases, the ascospores can bud off conidia that may fill the asci (e.g. ''Tympanis'') with hundreds of conidia, or the ascospores may fragment, e.g. some ''Cordyceps'', also filling the asci with smaller cells. Ascospores are nonmotile, usually single celled, but not infrequently may be coenocytic (lacking a septum), and in some cases coenocytic in multiple planes. Mitotic divisions within the developing spores populate each resulting cell in septate ascospores with nuclei. The term ocular chamber, or oculus, refers to the epiplasm (the portion of cytoplasm not used in ascospore formation) that is surrounded by the "bourrelet ...

Avocado
The avocado (''Persea americana'') is a medium-sized, evergreen tree in the laurel family (Lauraceae). It is native to the Americas and was first domesticated by Mesoamerican tribes more than 5,000 years ago. Then as now it was prized for its large and unusually oily fruit. The tree likely originated in the highlands bridging south-central Mexico and Guatemala. Its fruit, sometimes also referred to as an alligator or avocado pear, is botanically a large berry containing a single large seed. Avocado trees are partially self-pollinating, and are often propagated through grafting to maintain consistent fruit output. Avocados are presently cultivated in the tropical and Mediterranean climates of many countries. Mexico is the world's leading producer of avocados as of 2020, supplying nearly 30% of the global harvest in that year. The fruit of domestic varieties have smooth, buttery, golden-green flesh when ripe. Depending on the cultivar, avocados have green, brown, purplish, ...

Mango
A mango is an edible stone fruit produced by the tropical tree ''Mangifera indica''. It is believed to have originated in the region between northwestern Myanmar, Bangladesh, and northeastern India. ''M. indica'' has been cultivated in South and Southeast Asia since ancient times resulting in two types of modern mango cultivars: the "Indian type" and the "Southeast Asian type". Other species in the genus ''Mangifera'' also produce edible fruits that are also called "mangoes", the majority of which are found in the Malesian ecoregion. Worldwide, there are several hundred cultivars of mango. Depending on the cultivar, mango fruit varies in size, shape, sweetness, skin color, and flesh color which may be pale yellow, gold, green, or orange. Mango is the national fruit of India, Pakistan and the Philippines, while the mango tree is the national tree of Bangladesh. Etymology The English word ''mango'' (plural "mangoes" or "mangos") originated in the 16th century from the Por ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 been grow ...

Sphaeria
Sphaeria or Sphairia ( grc, Σφαιρία), later called Hiera (Ἱερά), is a former island of ancient Argolis described by Pausanias as in the immediate vicinity of Calaureia, and separated from the mainland (Peloponnesus) by a strait so narrow and shallow that there was a passage over it on foot. Pausanias wrote that on the island was the tomb of Sphaerus ( grc, Σφαίρος), who was a charioteer of Pelops. In addition, he wrote that according to legend Aethra saw Athena in a dream, and Athena told her to go to the island to give offerings to Sphaerus. Aethra went to the island and Poseidon had intercourse with her there. For this reason Aethra set up a temple of Athena Apaturia ( grc, Ἀθηνᾶς Ἀπατουρίας) on the island. Due to this the name of the island changed to Sacred (Ἱερά) Island. Furthermore, she also established a custom for the Troezenian maidens of dedicating their girdles before wedlock to Athena Apaturia. At present there is only one ...

Cryphonectria
''Cryphonectria'' is a fungal genus in the order Diaporthales. The most well-known and well-studied species in the genus is '' Cryphonectria parasitica'', the species which causes chestnut blight. The genus was, for a time, considered synonymous with '' Endothia'', but the two are now recognised as distinct. Taxonomic studies in 2006 limited the genus to four species, but a fifth, ''Cryphonectria naterciae'', was described in 2011 from Portugal. Species *'' Cryphonectria abscondita'' *''Cryphonectria acaciarum'' *''Cryphonectria cubensis'' *''Cryphonectria decipiens'' *''Cryphonectria japonica'' *''Cryphonectria macrospora'' *''Cryphonectria moriformis'' *''Cryphonectria naterciae'' *''Cryphonectria nitschkei'' *'' Cryphonectria parasitica'' *''Cryphonectria variicolor'' According to Murr) (And.et And.)Chestnut blight was first discovered in North America in 1904 on ''Castanea dentata The American chestnut (''Castanea dentata'') is a large, fast-growing deciduous tree of the ...

Giuseppe De Notaris
Giuseppe De Notaris (18 April 1805, Milan – 22 January 1877) was an Italian botanist generally known for his work with cryptogams native to Italy. He studied medicine at the University of Pavia, obtaining his medical degree in 1830. Having developed an interest in botany, by 1832 he had abandoned the field of medicine. In 1836 he accepted an assignment at the botanical garden in Turin, and a few years later, was named professor of botany and director of the botanical garden at the University of Genoa (1839). In 1872 he was appointed chair of botany at the University of Rome. In the field of mycology, he proposed the fungi family Hypocreaceae (1845). With Antonio Bey Figari (1804-1870), he described numerous species from the family Poaceae. With Figari, he was the binomial co-author of the grass genus ''Schistachne'' (synonym ''Stipagrostis''). Organisms with the specific epithet of ''notarisiana'' commemorate his name. Selected works * Muscologiae italicae spicilegium, 1837 ...

Lewis David De Schweinitz
Lewis David de Schweinitz (13 February 1780 – 8 February 1834) was a German-American botanist and mycologist. He is considered by some the "Father of North American Mycology", but also made significant contributions to botany. Education Born in Bethlehem, Pennsylvania, a great-grandson of Count Nikolaus Ludwig von Zinzendorf und Pottendorf, founder and patron of the Moravian Church, in 1787 Schweinitz was placed in the institution of the Moravian community at Nazareth, Pennsylvania, where he remained for 11 years and was a successful and industrious student. Schweinitz later entered the Theological seminary at Niesky (Saxony) in 1798. In 1805, he published the ''Conspectus Fungorum in Lusatiae'' in collaboration with his teacher, Professor J.B. Albertini. Early career In 1807 he went to Gnadenberg (in Silesia), then subsequently to Gnadau to work as a preacher in the Moravian church.

Diaporthales
Diaporthales is an order of sac fungi. Wijayawardene et al. in 2020 added a number of name families to the order. Diaporthales includes a number of plant pathogenic fungi, the most notorious of which is ''Cryphonectria parasitica'' (Murrill) Barr, the chestnut blight fungus that altered the landscape of eastern North America. Other diseases caused by members of this order include stem canker of soybeans ('' Diaporthe phaseolorum'' (Cooke & Ellis) Sacc. and its varieties), stem-end rot of citrus fruits ('' Diaporthe citri'' F.A. Wolf), and peach canker disease (''Phomopsis amygdali'' Del.). Some species produce secondary metabolites that result in toxicosis of animals such as lupinosis of sheep (''Diaporthe toxica'' P.M. Williamson et al.). A number of asexually reproducing plant pathogenic fungi also belong in the Diaporthales, such ''Greeneria uvicola'' (Berk. & Curt.) Punith., cause of bitter rot of grape, and ''Discula destructiva'' Redlin, cause of dogwood anthracnose, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
