Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ulmus 'Karagatch'
''Ulmus'' 'Karagatch' is a hybrid cultivar from Turkestan (from a region now part of Turkmenistan), selected in the early 20th century and considered either a backcrossing of ''U.'' × ''androssowii'' and ''U. pumila'', or simply a cultivar of × ''androssowii''. It was grown from seeds, introduced from Bairam Ali in Russian Turkestan by Arthur P. Davis in the 1930s, as ''U.'' 'Karagatch', under which name it was planted at Kew. More, D. & White, J. (2013).

Ophiostoma Ulmi
''Ophiostoma ulmi'' is a species of fungus in the family Ophiostomataceae. It is one of the causative agents of Dutch elm disease. It was first described under the name ''Graphium ulmi'', and later transferred to the genus ''Ophiostoma''. Dutch elm disease originated in Europe in the early 1900s. Elm trees were once an ecologically valuable tree that dominated mixed broadleaf forests, floodplains, and low areas near rivers and streams. They were planted in urban settings because of their aesthetic appeal and their ability to provide shade due to their V like shape. An outbreak of Dutch elm disease in the 1920s and again in the 1970s was responsible for the death of more than 40 million American elm trees. ''Ophiostoma ulmi'' was the first known cause of Dutch elm disease . Since its discovery in 1910, new forms of the fungus, specifically ''Ophiostoma novo-ulmi,'' have emerged and appear to be more resistant to control measures and more aggressive in their infection.

Scolytus Multistriatus
''Scolytus multistriatus'', the European elm bark beetle or smaller European elm bark beetle, is a bark beetle species in the genus ''Scolytus''. In Europe, while ''S. multistriatus'' acts as vector of the Dutch elm disease, caused by the Ascomycota ''Ophiostoma ulmi'', it is much less effective than the large elm bark beetle, '' S. scolytus''. ''S. multistriatus'' uses vanillin and syringaldehyde as signals to find a host tree during oviposition.Vanillin and Syringaldehyde as Attractants for ''Scolytus multistriatus'' (Coleoptera: Scolytidae).

Scolytus
''Scolytus'' is a genus of bark beetles (subfamily Scolytinae). It includes several species notorious for destroying trees in the forests. The Dutch elm disease is spread in North America by two species : the native elm bark beetle, ''Hylurgopinus rufipes'', and the European elm bark beetle, ''Scolytus multistriatus''. In Europe, while the aforementioned ''Scolytus multistriatus'' again acts as vector for infection, it is much less effective than the large elm bark beetle ''Scolytus scolytus''. Species Species include: *''Scolytus amygdali'' Guerin, 1847, the almond bark beetle *''Scolytus dentatus'' Bright, 1964 *''Scolytus fagi'' Walsh, 1867 *''Scolytus jacobsoni'' Spessivtzev, 1919 *''Scolytus laricis'' Blackman, 1934, the larch engraver *'' Scolytus mali'' ( Bechstein, 1805), the larger shothole borer *''Scolytus monticolae'' Swaine, 1917 *''Scolytus multistriatus'' (Marsham, 1802), the European elm bark beetle, smaller European elm bark beetle *''Scolytus muticus'' Say ...

Dutch Elm Disease
Dutch elm disease (DED) is caused by a member of the sac fungi (Ascomycota) affecting elm trees, and is spread by elm bark beetles. Although believed to be originally native to Asia, the disease was accidentally introduced into Americas, America, Europe, and New Zealand. In these regions it has devastated native populations of elms that did not have resistance to the disease. The name "Dutch elm disease" refers to its identification in 1921 and later in the Netherlands by Dutch phytopathologists Marie Beatrice Schol-Schwarz, Bea Schwarz and Christine Buisman, who both worked with professor Johanna Westerdijk. The disease affects species in the genera ''Ulmus'' and ''Zelkova''; therefore it is not specific to the Ulmus × hollandica, Dutch elm hybrid. Overview Dutch elm disease (DED) is caused by ascomycete microfungi. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
