Swainsona Greyana
''Swainsona greyana'', commonly known as Darling Pea or Hairy Darling Pea, is a shrubby perennial in the family Fabaceae that is native to Australia. It grows to 1.5 metres high, has hairy stems and pinnate leaves that are 10 to 15 cm long. Racemes of 12 to 20 pea flowers are produced from September to March in the species' native range. These have white, pink or purple corollas. The pods that follow are elliptic in shape and 30 to 50 mm long. It occurs on the banks of the lower Murray and Darling Rivers in South Australia, Victoria and New South Wales. The species was first formally described in 1846 by English botanist John Lindley in '' Edward's Botanical Register''. The plant contains the alkaloid swainsonine causing alpha-mannosidosis, a risk to grazing livestock. In 2014, thousands of livestock mostly sheep were killed in western New South Wales region, after consuming darling pea, due to its addictive nature. As toxicity builds up it attacks an enzyme invol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lindl
John Lindley FRS (5 February 1799 – 1 November 1865) was an English botanist, gardener and orchidologist. Early years Born in Catton, near Norwich, England, John Lindley was one of four children of George and Mary Lindley. George Lindley was a nurseryman and pomologist and ran a commercial nursery garden. Although he had great horticultural knowledge, the undertaking was not profitable and George lived in a state of indebtedness. As a boy he would assist in the garden and also collected wild flowers he found growing in the Norfolk countryside. Lindley was educated at Norwich School. He would have liked to go to university or to buy a commission in the army but the family could not afford either. He became Belgian agent for a London seed merchant in 1815. At this time Lindley became acquainted with the botanist William Jackson Hooker who allowed him to use his botanical library and who introduced him to Sir Joseph Banks who offered him employment as an assistant in his herba ...

Swainsonine
Swainsonine is an indolizidine alkaloid. It is a potent inhibitor of Golgi alpha-mannosidase II, an immunomodulator, and a potential chemotherapy drug. As a toxin in locoweed (likely its primary toxin) it also is a significant cause of economic losses in livestock industries, particularly in North America. It was first isolated from '' Swainsona canescens''. Pharmacology Swainsonine inhibits glycoside hydrolases, specifically N-linked glycosylation. Disruption of Golgi alpha-mannosidase II with swainsonine induces hybrid-type glycans. These glycans have a Man5GlcNAc2 core with processing on the 3-arm that resembles so-called complex-type glycans. The pharmacological properties of this product have not been fully investigated. Sources Some plants do not produce the toxic compound itself; they are host of endophytic fungi which produces swainsonine. Biosynthesis The biosynthesis of swainsonine has been investigated in the fungus ''Rhizoctonia leguminicola'', and it ini ...

Flora Of South Australia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fabales Of Australia
The Fabales are an order of flowering plants included in the rosid group of the eudicots in the Angiosperm Phylogeny Group II classification system. In the APG II circumscription, this order includes the families Fabaceae or legumes (including the subfamilies Caesalpinioideae, Mimosoideae, and Faboideae), Quillajaceae, Polygalaceae or milkworts (including the families Diclidantheraceae, Moutabeaceae, and Xanthophyllaceae), and Surianaceae. Under the Cronquist system and some other plant classification systems, the order Fabales contains only the family Fabaceae. In the classification system of Dahlgren the Fabales were in the superorder Fabiflorae (also called Fabanae) with three families corresponding to the subfamilies of Fabaceae in APG II. The other families treated in the Fabales by the APG II classification were placed in separate orders by Cronquist, the Polygalaceae within its own order, the Polygalales, and the Quillajaceae and Surianaceae within the Rosales.

Swainsona
''Swainsona'' is a large genus of flowering plants native to Australasia. There are 85 species, all but one of which are endemic to Australia. A member of the family Fabaceae (legumes), it is most closely related to the New Zealand genera ''Montigena'' (scree pea), ''Clianthus'' (kakabeak), and ''Carmichaelia'' ( New Zealand broom). ''Swainsona'' is named after English botanist Isaac Swainson. A few species are known to produce swainsonine, a phytotoxin harmful to livestock (see Locoweed). In Australia, animals intoxicated with swainsonine are said to be pea struck. ;Selected species *'' Swainsona acuticarinata'' ( A.T.Lee) Joy Thomps. *'' Swainsona adenophylla'' J.M.Black *'' Swainsona affinis'' ( A.T.Lee) Joy Thomps. *'' Swainsona beasleyana'' F.Muell. *'' Swainsona behriana'' F.Muell. ex J.M.Black *'' Swainsona brachycarpa'' Benth. *'' Swainsona bracteata'' (Maiden & Betche) Joy Thomps. *'' Swainsona burkei'' F.Muell. ex Benth. *'' Swainsona burkittii'' F.Muell. ex Benth ...

Australian Broadcasting Corporation
The Australian Broadcasting Corporation (ABC) is the national broadcaster of Australia. It is principally funded by direct grants from the Australian Government and is administered by a government-appointed board. The ABC is a publicly-owned body that is politically independent and fully accountable, with its charter enshrined in legislation, the ''Australian Broadcasting Corporation Act 1983''. ABC Commercial, a profit-making division of the corporation, also helps to generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an act of federal parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A-class radio stations. The ABC was given statutory powers that reinforced its independence from the government and enhanced its news-gathering role. Modelled after the British Broadcasting Corporation (BBC), which is funded by a tel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Warrumbungle National Park
Warrumbungle National Park is a heritage listed national park located in the Orana region of New South Wales, Australia. The national park is located approximately northwest of Sydney and contained within . The park attracts approximately visitors per annum. The national park is based on the geographical Warrumbungle Mountain Range, sometimes shortened to the Warrumbungles, and thus the park name is often heard in the plural. The park lies within the Pilliga Important Bird Area, so identified by BirdLife International because of its importance for a range of woodland bird species, many of which are threatened. Warrumbungle National Park was added to the Australian National Heritage List in December 2006. On 4 July 2016, the park was the first within Australia to be certified as a Dark Sky Park by the International Dark Sky Association.

Alpha-mannosidosis
Alpha-mannosidosis is a lysosomal storage disorder, first described by Swedish physician Okerman in 1967.''Malm D, Nilssen O (2008). "Alpha-mannosidosis". Orphanet J Rare Dis. 3 (1): 21. doi:10.1186/1750-1172-3-21. PMC 2515294 . PMID 18651971'' In humans it is known to be caused by an autosomal recessive genetic mutation in the gene MAN2B1, located on chromosome 19, affecting the production of the enzyme alpha-D-mannosidase, resulting in its deficiency.''Alpha-Mannosidosis Mutation Database. Tromsoe University. Available at'' Consequently, if both parents are carriers, there will be a 25% chance with each pregnancy that the defective gene from both parents will be inherited, and the child will develop the disease. There is a two in three chance that unaffected siblings will be carriers (Figure 1). In livestock alpha-mannosidosis is caused by chronic poisoning with swainsonine from locoweed.
