Alchemilla Alpina
''Alchemilla alpina'', commonly known as alpine lady's-mantle, is an arctic-montane herbaceous perennial plant native to Europe and Southern Greenland. Alpine lady's-mantle has been used for centuries as an herbal remedy, and is used in horticulture as a ground cover and in rock gardens. Description Alpine lady's-mantle is a perennial plant with a woody rhizome growing to a height of between . The weak stems are silkily hairy and grow from a basal rosette and the leaves are palmate with about seven lanceolate leaflets with toothed tips, smooth above and densely hairy underneath. There are alternate pairs of leaves on the stems and the inflorescence forms a dense cyme. The flowers are lime green with four sepals, no petals, four stamens and a solitary carpel. They are hermaphrodite and the seeds develop apomictically without being fertilised. The flowers begin to bloom in June and fade in September and their seeds can be collected from August to October. Because the seeds develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botrytis Cinerea
''Botrytis cinerea'' is a necrotrophic fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as "botrytis bunch rot"; in horticulture, it is usually called "grey mould" or "gray mold". The fungus gives rise to two different kinds of infections on grapes. The first, grey rot, is the result of consistently wet or humid conditions, and typically results in the loss of the affected bunches. The second, noble rot, occurs when drier conditions follow wetter, and can result in distinctive sweet dessert wines, such as Sauternes (wine), Sauternes or the Aszú of Tokaji/Grasă de Cotnari. The species name ''Botrytis cinerea'' is derived from the Latin for "grapes like ashes"; although poetic, the "grapes" refers to the bunching of the fungal spores on their Conidium, conidiophores, and "ashes" just refers to the greyish colour of the spores ''en masse''. The fungus is usually referred to by its anamorph (asexual form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alchemilla
''Alchemilla'' is a genus of herbaceous perennial plants in the family Rosaceae, with the common name lady's mantle applied generically as well as specifically to ''Alchemilla mollis'' when referred to as a garden plant. The plant used as a herbal tea or for medicinal usage such as gynaecological disorders is '' Alchemilla xanthochlora'' or in Middle Europe the so-called common lady's mantle ''Alchemilla vulgaris''. There are about 700 species, the majority native to cool temperate and subarctic regions of Europe and Asia, with a few species native to the mountains of Africa and the Americas. Most species of ''Alchemilla'' are clump-forming or mounded perennials with basal leaves arising from woody rhizomes. Some species have leaves with lobes that radiate from a common point and others have divided leaves—both are typically fan-shaped with small teeth at the tips. The long-stalked, gray-green to green leaves are often covered with soft hairs, and show a high degree of water-re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phoma Alchemillae
''Phoma'' is a genus of common coelomycetous soil fungi. It contains many plant pathogenic species. Description Spores are colorless and unicellular. The pycnidia are black and depressed in the tissues of the host. ''Phoma'' is arbitrarily limited to those species in which the spores are less than 15 µm as the larger spored forms have been placed in the genus ''Macrophoma''. The most important species include ''Phoma beta'' which is the cause of the heart rot and blight of beets, ''Phoma batata'' that produces a dry rot of sweet potato, and ''Phoma solani''. Taxonomy About 140 ''Phoma'' taxa have been defined and recognized which may be divided into two large groups: (i) plurivorous fungi, generally saprobic or weakly parasitic, mainly from temperate regions in Eurasia, but occasionally also found in other parts of the world (including areas with cool or warm climates); and (ii) specific pathogens of cultivated plants. However other estimates place the number o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quaedvlieg (named: Re-evaluating ''Mycosphaerella'' and allied genera). Species belonging to the fungal genus ''Mycosphaerella'' (1884) (''Capnodiales'', ''Dothideomycetes'') have evolved as endophytes, saprotrophs and symbionts, but mostly ''Mycosphaerella'' species are foliicolous plant pathogens which are the cause of significant economical losses in both temperate and tropical crops worldwide. The generic concept of Mycosphaerella is based on the type species of the genus, ''M. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mutation
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication (translesion synthesis). Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce detectable changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. Mutation is the ultimate source o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbaceous
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the ''Shorter Oxford English Dictionary'' defines "herb" as: #"A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; #"A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: #"Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; #"BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the parts of ...
