Ampelographers
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 wh ...

Vitis Labrusca BB-1913
''Vitis'' (grapevine) is a genus of 81 accepted species of vining plants in the flowering plant family Vitaceae. The genus consists 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 dioecious. 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 berrie ...

Carole Meredith
Carole P. Meredith is an American grape geneticist and was a professor at the UC Davis Department of Viticulture and Enology, 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 Variety (botany), 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 Zinfandel, Primitivo, and Crljenak Kaštelanski are identical. The varieties Douce noir, Charbono a ...

Cornell University Press
The Cornell University Press is the university press of Cornell University, an Ivy League university in Ithaca, New York. It is 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 disci ...

Pinot Meunier
Pinot Meunier (), also known as Meunier or Schwarzriesling (), is a variety of red wine grape most noted for being one of the three main varieties used in the production of Champagne (the other two are the red variety Pinot noir and the white Chardonnay). Until recently, producers in Champagne generally did not acknowledge Pinot Meunier, preferring to emphasise the use of the other noble varieties, but now Pinot Meunier is gaining recognition for the body and richness it contributes to Champagne. Pinot Meunier is approximately one-third of all the grapes planted in Champagne. It is a chimeric mutation of Pinot: its inner cell layers are composed of a Pinot genotype which is close to Pinot noir or Pinot gris; the outer, epidermal, layer is, however, made up of a mutant, distinctive, genotype. Pinot Meunier was first mentioned in the 16th century,

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 substitution, 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. Mutati ...

Gene
In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. 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 non-coding genes. During gene expression (the synthesis of Gene product, RNA or protein from a gene), DNA is first transcription (biology), copied into RNA. RNA can be non-coding RNA, directly functional or be the intermediate protein biosynthesis, template for the synthesis of a protein. The transmission of genes to an organism's offspring, is the basis of the inheritance of phenotypic traits from one generation to the next. These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of the population (biology), population of a given species. The genotype, along with environmental and developmental factors, ultimately determines the phenotype ...

Sangiovese
Sangiovese is a red Italian wine grape variety that derives its name from the Latin , "blood of Jove, Jupiter". Sangiovese Grosso, used for traditionally powerful and slow maturing red wines, is primarily grown in the central regions of Italy, particularly in Tuscany, where it is the dominant grape variety. Here, Sangiovese thrives in various subregions, including Chianti, Montalcino, and Montepulciano, whose diverse terroirs winemakers put to good use to craft wines that reflect the land's unique nuances. Sangiovese's ability to express terroir and age gracefully has earned it a revered status among wine enthusiasts worldwide, cementing its place as one of Italy's most cherished grape varieties. Because of its distinctive character and versatility, Sangiovese is the singular or primary grape variety used in iconic Italian wines from Tuscany such as bold and age-worthy Brunello di Montalcino and Vino Nobile di Montepulciano, to vibrant and fruity wines like Morellino di Scans ...

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 Pribidrag, as well as to the Primitivo variety traditionally grown in Apulia, Italy, where it was introduced in the 18th century, and Kratošija in Montenegro and Macedonia . 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 red wine depends on the ripeness of the grapes from which it is made. Red berry frui ...

Genetic Fingerprinting
DNA profiling (also called DNA fingerprinting and genetic fingerprinting) is the process of determining an individual's deoxyribonucleic acid (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 mid 1970s, 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 ...

Ampelos
Ampelos (, lit."Vine") or Ampelus (Latin) was a personification of the grapevine and lover of Dionysus in Greek and Bacchus in Roman mythology. He was a satyr that either turned into a constellation or the grape vine, due to Dionysus. Mythology Nonnus In Nonnus's etiology, Ampelos is a beautiful satyr youth, who was loved by Dionysus, and whose death was foreseen by the god. There are two versions of his death and Dionysus's reaction to it. According to Nonnus, Ampelos was gored to death by a wild bull after he mocked the goddess Selene, a scene described as follows: :" mpelos, love of Dionysos, rode upon the back of a wild bull:He shouted boldly to the fullfaced Moon (Mene)—'Give me best, Selene, horned driver of cattle! Now I am both—I have horns and I ride a bull!' : : :So he called out boasting to the round Moon. Selene looked with a jealous eye through the air, to see how Ampelos rode on the murderous marauding bull. She sent him a cattlechasing gadfly; and the bull, ...
