Barrie Juniper
Barrie Edward Juniper (21 February 1932–29 January 2023) was a British plant scientist. He was emeritus reader in plant sciences at the University of Oxford and Fellow Emeritus of St Catherine's College, Oxford. Career Juniper undertook much research into apples and fruit-related subjects and was the author of many associated papers and scholarly works. Intrigued by the differing opinions on the source of our modern day domestic apples, he embarked on a project to discover and record their origin and geographical spread over time.Mid Shires Orchard Group – "Obituary of Professor Barrie Juniper" Using DNA analysis of apple varieties from across the world, his work determined that all domestic apples shared the same DNA and that this was not the same as the various wild crab apple species known around the world. Until that point, it had been assumed by many that the domestic apple had been developed from these. However, a relationship was found with the wild apple forests of t ...

Plant Sciences
Botany, also called plant science, is the branch of natural science and biology studying plants, especially their anatomy, taxonomy, and ecology. A botanist or plant scientist is a scientist who specialises in this field. "Plant" and "botany" may be defined more narrowly to include only land plants and their study, which is also known as phytology. Phytologists or botanists (in the strict sense) study approximately 410,000 species of land plants, including some 391,000 species of vascular plants (of which approximately 369,000 are flowering plants) and approximately 20,000 bryophytes. Botany originated as prehistoric herbalism to identify and later cultivate plants that were edible, poisonous, and medicinal, making it one of the first endeavours of human investigation. Medieval physic gardens, often attached to monasteries, contained plants possibly having medicinal benefit. They were forerunners of the first botanical gardens attached to universities, founded from the 1540s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinians, Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Phenotypic trait, Trait inheritance and Molecular genetics, molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the Cell (bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Oxford
The University of Oxford is a collegiate university, collegiate research university in Oxford, England. There is evidence of teaching as early as 1096, making it the oldest university in the English-speaking world and the List of oldest universities in continuous operation, second-oldest continuously operating university globally. It expanded rapidly from 1167, when Henry II of England, Henry II prohibited English students from attending the University of Paris. When disputes erupted between students and the Oxford townspeople, some Oxford academics fled northeast to Cambridge, where they established the University of Cambridge in 1209. The two English Ancient university, ancient universities share many common features and are jointly referred to as ''Oxbridge''. The University of Oxford comprises 43 constituent colleges, consisting of 36 Colleges of the University of Oxford, semi-autonomous colleges, four permanent private halls and three societies (colleges that are depar ...

St Catherine's College, Oxford
St Catherine's College (colloquially called St Catz or Catz) is one of the Colleges of the University of Oxford, constituent colleges of the University of Oxford. In 1974, it was also one of the first men's colleges to admit women. It has 528 undergraduate students, 385 graduate students and 37 visiting students as of December 2020, making it one of the largest colleges in either Oxford or University of Cambridge, Cambridge. Designed by Danes, Danish architect Arne Jacobsen, the college was built in an egalitarian architectural style that maximises the number of rooms for academically qualified students who lack the financial resources to study at Oxford. In September 2023, access to areas of the college was restricted due to safety concerns around the use of reinforced autoclaved aerated concrete (RAAC). The college developed out of the university's St Catherine's Society; it was granted full status as a college in 1962 by the historian Alan Bullock, who became the first master ...

Crab Apple
''Malus'' ( or ) is a genus of about 32–57 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple, crab apples (sometimes known in North America as crabapples) and wild apples. The genus is native to the temperate zone of the Northern Hemisphere. Description Apple trees are typically tall at maturity, with a dense, twiggy crown. The leaves are long, alternate, simple, with a serrated margin. The flowers are borne in corymbs, and have five petals, which may be white, pink, or red, and are perfect, with usually red stamens that produce copious pollen, and a half-inferior ovary; flowering occurs in the spring after 50–80 growing degree-days, varying greatly according to subspecies and cultivar. Many apples require cross-pollination between individuals by insects (typically bees, which freely visit the flowers for both nectar and pollen); these are called self-sterile, so self-pollination is impossible, making polli ...

Tian Shan
The Tian Shan, also known as the Tengri Tagh or Tengir-Too, meaning the "Mountains of God/Heaven", is a large system of mountain ranges in Central Asia. The highest peak is Jengish Chokusu at high and located in Kyrgyzstan. Its lowest point is at the Turpan Depression, which is below sea level. The Tian Shan is sacred in Tengrism. Its second-highest peak is known as Khan Tengri, which can be translated as "Lord of the Spirits". At the 2013 Conference on World Heritage, the eastern portion of Tian Shan in western China's Xinjiang Region was listed as a World Heritage Site. The western portion in Kyrgyzstan, Kazakhstan, and Uzbekistan was then listed in 2016. Geography Tian Shan with the ancient Silk Road The Tian Shan range is located north and west of the Taklamakan Desert and directly north of the Tarim Basin. It straddles the border regions of Kazakhstan, Kyrgyzstan, Uzbekistan and Xinjiang in Northwest China. To the south, it connects with the Pamir Mountains ...

People Associated With St Catherine's College, Oxford
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
