Ampelography
Ampelography ( ἄμπελος, "vine" + γράφος, "writing") is the field of botany concerned with the identification and classification of grapevines, ''Vitis'' spp. Traditionally this has been done by comparing the shape and colour of the vine leaves and grape berries; more recently the study of vines has been revolutionised by DNA fingerprinting. Early history The grape vine is an extremely variable species and some varieties, such as Pinot, mutate particularly frequently. At the same time, the wine and table grape industries have been important since ancient times, so large sums of money can depend on the correct identification of different varieties and clones of grapevines. The science of ampelography began seriously in the 19th century, when it became important to understand more about the different species of vine, as they had very different resistance to disease and pests such as phylloxera. Many vine identification books were published at this time, one of whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viticulture
Viticulture (from the Latin word for '' vine'') or winegrowing (wine growing) is the cultivation and harvesting of grapes. It is a branch of the science of horticulture. While the native territory of '' Vitis vinifera'', the common grape vine, ranges from Western Europe to the Persian shores of the Caspian Sea, the vine has demonstrated high levels of adaptability to new environments, hence viticulture can be found on every continent except Antarctica. Duties of the viticulturist include monitoring and controlling pests and diseases, fertilizing, irrigation, canopy management, monitoring fruit development and characteristics, deciding when to harvest, and vine pruning during the winter months. Viticulturists are often intimately involved with winemakers, because vineyard management and the resulting grape characteristics provide the basis from which winemaking can begin. A great number of varieties are now approved in the European Union as true grapes for winegrowing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Galet
Pierre Galet (28 January 1921 – 30 December 2019) was a French ampelographer and author who was an influential figure within ampelography in the 20th century and before DNA typing was widely introduced. Beginning in the 1950s, Pierre Galet introduced a system for identifying varieties based on the shape, contours and characteristics of the leaves of the vines, petioles, growing shoots, shoot tips, grape clusters, as well as the colour, size, seed content and flavour of the grapes. The impact and comprehensiveness of his work earned him the consideration as the "father of modern ampelography". J. Robinson (ed) ''"The Oxford Companion to Wine"'' Third Edition pg 295 Oxford University Press 2006 He started publishing within ampelography in the 1950s and his Ph.D. thesis was presented in 1967. He has also written popular science books on grape varieties. Galet was active at the École Nationale Supérieure Agronomique de Montpellier. Biography Pierre Galet was born in Monaco in ...

Cornell University Press
The Cornell University Press is the university press of Cornell University; currently housed in Sage House, the former residence of Henry William Sage. It was first established in 1869, making it the first university publishing enterprise in the United States, but was inactive from 1884 to 1930. The press was established in the College of the Mechanic Arts (as mechanical engineering was called in the 19th century) because engineers knew more about running steam-powered printing presses than literature professors. Since its inception, The press has offered work-study financial aid: students with previous training in the printing trades were paid for typesetting and running the presses that printed textbooks, pamphlets, a weekly student journal, and official university publications. Today, the press is one of the country's largest university presses. It produces approximately 150 nonfiction titles each year in various disciplines, including anthropology, Asian studies, bio ...

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 replication, DNA or viral replication, mitosis, or meiosis or other types of DNA repair#DNA damage, 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 (DNA repair#Translesion synthesis, translesion synthesis). Mutations may also result from Insertion (genetics), insertion or Deletion (genetics), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene
In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as ...

Sangiovese
Sangiovese (, also , , ) is a red Italian wine grape variety that derives its name from the Latin ''sanguis Jovis'', "the blood of Jupiter". Though it is the grape of most of central Italy from Romagna down to Lazio (the most widespread grape in Tuscany), Campania and Sicily, outside Italy it is most famous as the only component of Brunello di Montalcino and Rosso di Montalcino and the main component of the blends Chianti, Carmignano, Vino Nobile di Montepulciano and Morellino di Scansano, although it can also be used to make varietal wines such as Sangiovese di Romagna and the modern " Super Tuscan" wines like Tignanello. Sangiovese was already well known by the 16th century. Recent DNA profiling by José Vouillamoz of the Istituto Agrario di San Michele all’Adige suggests that Sangiovese's ancestors are Ciliegiolo and Calabrese Montenuovo. The former is well known as an ancient variety in Tuscany, the latter is an almost-extinct relic from Calabria, the toe of It ...

Zinfandel
Zinfandel (also known as Primitivo) is a variety of black-skinned wine grape. The variety is grown in over 10 percent of California vineyards. DNA analysis has revealed that it is genetically equivalent to the Croatian grapes Crljenak Kaštelanski and Tribidrag, as well as to the Primitivo variety traditionally grown in Apulia (the "heel" of Italy), where it was introduced in the 18th century and Kratošija in Montenegro.Jancis Robinson, 'The Great Grapevine'' in ''The Financial Times'', October 12th, 2012 The grape found its way to the United States in the mid-19th century, where it became known by variations of a name applied to a different grape, likely " Zierfandler" from Austria. The grapes typically produce a robust red wine, although, in the United States, a semi-sweet rosé (blush-style) wine called White Zinfandel has six times the sales of the red wine. The grape's high sugar content can be fermented into levels of alcohol exceeding 15 percent. The taste of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Fingerprinting
DNA profiling (also called DNA fingerprinting) is the process of determining an individual's DNA characteristics. DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding. DNA profiling is a forensic technique in criminal investigations, comparing criminal suspects' profiles to DNA evidence so as to assess the likelihood of their involvement in the crime. It is also used in paternity testing, to establish immigration eligibility, and in genealogical and medical research. DNA profiling has also been used in the study of animal and plant populations in the fields of zoology, botany, and agriculture. Background Starting in the 1980s, scientific advances allowed the use of DNA as a material for the identification of an individual. The first patent covering the direct use of DNA variation for forensicsUS5593832A was filed by Jeffrey Glassberg in 1983, based upon work he had done while at Rockefeller University in the United States in 198 ...

Vitis Labrusca BB-1913
''Vitis'' (grapevine) is a genus of 79 accepted species of vining plants in the flowering plant family Vitaceae. The genus is made up of species predominantly from the Northern Hemisphere. It is economically important as the source of grapes, both for direct consumption of the fruit and for fermentation to produce wine. The study and cultivation of grapevines is called viticulture. Most cultivated ''Vitis'' varieties are wind-pollinated with hermaphroditic flowers containing both male and female reproductive structures, while wild species are dieceous. These flowers are grouped in bunches called inflorescences. In many species, such as ''Vitis vinifera'', each successfully pollinated flower becomes a grape berry with the inflorescence turning into a cluster of grapes. While the flowers of the grapevines are usually very small, the berries are often large and brightly colored with sweet flavors that attract birds and other animals to disperse the seeds contained within the berri ...

Carole Meredith
Carole P. Meredith is an American grape geneticist and was a professor at the Department of Viticulture and Enology of University of California, Davis. Career Before she retired in 2003, Meredith and her research group pioneered the use of DNA typing to differentiate ''Vitis vinifera'' grape varieties and for elucidating their parentage, which gives insight into the varieties' history and place of origin. In 1996, Meredith and her research established the parentage of Cabernet Sauvignon, which was the first application of such techniques. Later, Chardonnay, Syrah, and Zinfandel followed.Lagier-Meredith: Who we are The research group showed that the varieties , |
