Zea Diploperennis
''Zea diploperennis'', the diploperennial teosinte, is a species of grass (family: Poaceae) in the genus '' Zea'' and a teosinte (wild relative of maize or corn). It is perennial. Conservation Virtually all populations of this teosinte are either threatened or endangered: ''Z. diploperennis'' exists in an area of only a few square miles. The Mexican and Nicaraguan governments have taken action in recent years to protect wild teosinte populations, using both ''in situ'' and ''ex situ'' conservation methods. Currently, a large amount of scientific interest exists in conferring beneficial teosinte traits, such as insect resistance, perennialism, and flood tolerance, to cultivated maize lines, although this is very difficult due to linked deleterious teosinte traits. Researchers are studying ''Z. diploperennis'' as its genes provide resistance against ''Striga ''Striga'', commonly known as witchweed, is a genus of parasitic plants that occur naturally in parts of Africa, Asia, an ...

Conservatoire Botanique National De Brest
The Conservatoire botanique national de Brest (32 hectares) is a notable botanical garden located at 52 Allée du Bot, Brest, Finistère, in the region of Brittany, France. It is open daily without charge. The conservatory site was formerly a quarry and rubbish dump, purchased in 1971 by the municipality to create open space. The conservatory itself was founded in 1977 with a primary mission of preserving endangered species from the Armorican Massif (including parts of Brittany, Basse-Normandie and Pays de la Loire), France, Europe, and islands around the world, but also including plants from China, Japan, the Americas, Australia, and New Zealand. Since 1990 it has been designated a National Botanical Conservation Center to protect endangered and protected plants of the Armorican Massif. Today the conservatory contains a remarkable collection of endangered plants, totaling about 1700 species, of which 20 species have been preserved in large part by the conservatory's actions.

Flora Of Central America
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grasses Of North America
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, primaril ...

Plant Breeding (journal)
Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. It has been used to improve the quality of nutrition in products for humans and animals. The goals of plant breeding are to produce crop varieties that boast unique and superior traits for a variety of applications. The most frequently addressed agricultural traits are those related to biotic and abiotic stress tolerance, grain or biomass yield, end-use quality characteristics such as taste or the concentrations of specific biological molecules (proteins, sugars, lipids, vitamins, fibers) and ease of processing (harvesting, milling, baking, malting, blending, etc.). Plant breeding can be performed through many different techniques ranging from simply selecting plants with desirable characteristics for propagation, to methods that make use of knowledge of genetics and chromosomes, to more complex molecular techniques. Genes in a plant are what determine what type of qualit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hugh Iltis
Hugh Iltis (April 7, 1925 – December 19, 2016) was a professor of botany and director of the herbarium at the University of Wisconsin–Madison. While he is most noted as a scientist for his role in the discovery of perennial teosinte (''Zea diploperennis''), a wild diploid relative of modern maize (''Zea mays''), he is also remembered as an outspoken environmental conservationist. Life and work He was born Hugo Hellmut Iltis to Anni (née Liebscher) and Hugo Iltis, a botanist and geneticist who was a life sciences teacher at the German-language gymnasium of Brünn (Brno). His father was also the first biographer of Gregor Mendel and a vocal opponent of Nazi "racial science". In the fall of 1938, the Iltis family was granted visas to enter the United States thanks to the intercession of the Emergency Committee in Aid of Displaced Foreign Scholars, along with affidavits of endorsement from Albert Einstein and Franz Boas. In January 1939, when Hitler's military was preparing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
