Anthony Cashmore
Anthony R. Cashmore (b. 22 Jan 1941) is a biochemist and plant molecular biologist, best known for identifying cryptochrome photoreceptor proteins. These specialized proteins are critical for plant development and play an essential role in circadian rhythms of plants and animals. A Professor emeritus in the Department of Biology at the University of Pennsylvania, Cashmore led the Plant Science Institute from the time of his appointment in 1986 until his retirement in 2011. He was elected to the National Academy of Sciences in 2003. Early life and education Born in Auckland (New Zealand) in 1941, Cashmore grew up in Manawaru and Te Aroha. As a teenager, Cashmore worked in Palmerston North in the Grasslands Division of New Zealand's Department of Scientific and Industrial Research (DSIR). Cashmore enrolled at the University of Auckland, majoring in chemistry and completing a Bachelor of Science degree in 1962, Master of Science degree in 1963, and Ph.D. degree in 1966. In 1968 ...

Plant Biology
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Photoreceptor Protein
Photoreceptor proteins are light-sensitive proteins involved in the sensing and response to light in a variety of organisms. Some examples are rhodopsin in the photoreceptor cells of the vertebrate retina, phytochrome in plants, and bacteriorhodopsin and bacteriophytochromes in some bacteria. They mediate light responses as varied as visual perception, phototropism and phototaxis, as well as responses to light-dark cycles such as circadian rhythm and other photoperiodisms including control of flowering times in plants and mating seasons in animals. Structure Photoreceptor proteins typically consist of a protein attached to a non-protein chromophore (sometimes referred as photopigment, even so photopigment may also refer to the photoreceptor as a whole). The chromophore reacts to light via photoisomerization or photoreduction, thus initiating a change of the receptor protein which triggers a signal transduction cascade. Chromophores found in photoreceptors include retinal (reti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambridge
Cambridge ( ) is a university city and the county town in Cambridgeshire, England. It is located on the River Cam approximately north of London.

Department Of Scientific And Industrial Research (New Zealand)
The Department of Scientific and Industrial Research (DSIR) is a now-defunct government science agency in New Zealand, founded in 1926 and broken into Crown Research Institutes in 1992. Foundation DSIR was founded in 1926 by Ernest Marsden after calls from Ernest Rutherford for government to support education and research and on the back of the Imperial Economic Conference in London in October and November 1923, when various colonies discussed setting up such departments. It initially received funding from sources such as the Empire Marketing Board. The initial plans also included a new agricultural college, to be jointly founded by Auckland and Victoria University Colleges, Palmerston North was chosen as the site for this and it grew to become Massey University. Structure DSIR initially had five divisions: * Grasslands in Palmerston North * Plant Diseases in Auckland * Entomology, attached to the Cawthron Institute in Nelson * Soil Survey (later Soil Bureau) in Taita * Ag ...

It is northeast of Hamilton and south of Thames. It sits at the foot of Mount Te Aroha, the highest point in the Kaimai Range. History The name Te Aroha derives from the Māori name of Mount Te Aroha. In one version, Rāhiri, the eponymous ancestor of Ngāti Rāhiri Tumutumu, climbed the mountain and saw his homeland in the distance and felt a sense of love () for it. The town is properly named ; meaning 'inland', so the town is named "love flowing inland". In some Tainui traditions, Rakataura, a tohunga of the ''Tainui'' waka, was one of the first people to leave the waka, settling at Rarotonga / Mount Smart. After a period of time, Rakataura decided to leave Tāmaki Makaurau and travel south, however during the journey his wife Kahukeke died. Eventually Rakataura settled at Te Aroha, naming the ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Professor
Professor (commonly abbreviated as Prof.) is an Academy, academic rank at university, universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of List of academic ranks, academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital let ...

Circadian Clock
A circadian clock, or circadian oscillator, is a biochemical oscillator that cycles with a stable phase (waves), phase and is synchronized with solar time. Such a clock's ''in vivo'' period is necessarily almost exactly 24 hours (the earth's current day, solar day). In most living things, internally synchronized circadian clocks make it possible for the organism to anticipate daily environmental changes corresponding with the day–night cycle and adjust its biology and behavior accordingly. The term circadian derives from the Latin ''circa'' (about) ''dies'' (a day), since when taken away from external cues (such as environmental light), they do not run to exactly 24 hours. Clocks in humans in a lab in constant low light, for example, will average about 24.2 hours per day, rather than 24 hours exactly. The normal body clock oscillates with an endogenous period of exactly 24 hours, it Entrainment (chronobiology), entrains, when it receives sufficient daily corrective signals from ...
