Peter K. Hepler
Peter Klock Hepler HonFRMS (born 1936) is the Constantine J. Gilgut and Ray Ethan Torrey Professor Emeritus in the Biology Department of the University of Massachusetts at Amherst who is notable for his work on elucidating the roles of calcium, membranes and the cytoskeleton in plant cell development and cell motility. Personal life Peter Klock Hepler was born on October 29, 1936, in Dover, New Hampshire, to Jesse Raymond Hepler and Rebecca Orpha Peterson Hepler.

Dover, New Hampshire
Dover is a city in Strafford County, New Hampshire, United States. The population was 32,741 at the 2020 census, making it the largest city in the New Hampshire Seacoast region and the fifth largest municipality in the state. It is the county seat of Strafford County, and home to Wentworth-Douglass Hospital, the Woodman Institute Museum, and the Children's Museum of New Hampshire. Etymology First recorded in its Latinised form of ''Portus Dubris'', the word "Dover" derives from the Brythonic word for "waters" (''dwfr'' in Middle Welsh). The same element is present in the word's French (''Douvres'') and Modern Welsh (''Dofr'') forms. History Settlement The first known European to explore the region was Martin Pring from Bristol, England, in 1603. In 1623, William and Edward Hilton settled at Pomeroy Cove on Dover Point, making Dover the oldest permanent settlement in New Hampshire, and seventh in the United States. One of the colony's four original townships, it then includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelham, Massachusetts
Pelham is a town in Hampshire County, Massachusetts, United States. The population was 1,280 at the 2020 census. Its ZIP Code is shared with Amherst. Pelham is part of the Springfield, Massachusetts Metropolitan Statistical Area. History Pelham (pronounced "PEL-am"; the "h" is silent) was part of the Equivalent Lands compromise, and was first settled in 1738 by mostly Presbyterian Scotch-Irish immigrants. It was officially incorporated in 1743. The town is named for the Pelham family; Henry Pelham was Prime Minister of the United Kingdom at the time of the town's incorporation. The town is best known as being home to Daniel Shays, leader of Shays' Rebellion, a series of protests against crushing austerity measures in Massachusetts during 1786 and 1787. The rebellion, planned in Conkey's Tavern in town, drew support from many towns in central and western Massachusetts, but it met its practical end when the angry farmers' force refused to fight Governor Bowdoin's army and the ...

Marine Biological Laboratory
The Marine Biological Laboratory (MBL) is an international center for research and education in biological and environmental science. Founded in Woods Hole, Massachusetts, in 1888, the MBL is a private, nonprofit institution that was independent for most of its history, but became officially affiliated with the University of Chicago on July 1, 2013. It also collaborates with numerous other institutions. As of 2022, 60 Nobel Prize winners have been affiliated with MBL as students, faculty members or researchers. In addition since 1960, there have been, 137 Howard Hughes Medical Institute investigators, early career scientists, international researchers, and professors; 306 members of the National Academy of Sciences; and 236 Members of the American Academy of Arts and Sciences who have been affiliated with the lab.

Endosperm
The endosperm is a tissue produced inside the seeds of most of the flowering plants following double fertilization. It is triploid (meaning three chromosome sets per nucleus) in most species, which may be auxin-driven. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. This can make endosperm a source of nutrition in animal diet. For example, wheat endosperm is ground into flour for bread (the rest of the grain is included as well in whole wheat flour), while barley endosperm is the main source of sugars for beer production. Other examples of endosperm that forms the bulk of the edible portion are coconut "meat" and coconut "water", and corn. Some plants, such as orchids, lack endosperm in their seeds. Origin of endosperm Ancestral flowering plants have seeds with small embryos and abundant endosperm. The evolutionary development of flowering plants trends towards plants with mature seeds with little or no endosp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phragmoplast
image:Phragmoplast.png, 300px, Phragmoplast and cell plate formation in a plant cell during cytokinesis. Left side: Phragmoplast forms and cell plate starts to assemble in the center of the cell. Towards the right: Phragmoplast enlarges in a donut-shape towards the outside of the cell, leaving behind mature cell plate in the center. The cell plate will transform into the new cell wall once cytokinesis is complete. The ''phragmoplast'' is a plant cell specific structure that forms during late cytokinesis. It serves as a scaffold for cell plate assembly and subsequent formation of a new cell wall separating the two daughter cells. The phragmoplast can only be observed in Phragmoplastophyta, a clade that includes the Coleochaetophyceae, Zygnematophyceae, Mesotaeniaceae, and Embryophyta (land plants). Some algae use another type of microtubule array, a phycoplast, during cytokinesis.P.H. Raven, R.F. Evert, S.E. Eichhorn (2005): ''Biology of Plants'', 7th Edition, W.H. Freeman and Compa ...

Mitotic Apparatus
In cell biology, the spindle apparatus refers to the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis, a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis, a process that produces gametes with half the number of chromosomes of the parent cell. Besides chromosomes, the spindle apparatus is composed of hundreds of proteins. Microtubules comprise the most abundant components of the machinery. Spindle structure Attachment of microtubules to chromosomes is mediated by kinetochores, which actively monitor spindle formation and prevent premature anaphase onset. Microtubule polymerization and depolymerization dynamic drive chromosome congression. Depolymerization of microtubules generates tension at kinetochores; bipolar attachment of sister kinetochores to microtubules emanating from opposite cell p ...

Malaria
Malaria is a mosquito-borne infectious disease that affects humans and other animals. Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches. In severe cases, it can cause jaundice, seizures, coma, or death. Symptoms usually begin ten to fifteen days after being bitten by an infected mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria. Malaria is caused by single-celled microorganisms of the ''Plasmodium'' group. It is spread exclusively through bites of infected ''Anopheles'' mosquitoes. The mosquito bite introduces the parasites from the mosquito's saliva into a person's blood. The parasites travel to the liver where they mature and reproduce. Five species of ''Plasmodium'' can infect and be spread by h ...
