RuBisCO
Ribulose-1,5-bisphosphate carboxylase-oxygenase, commonly known by the abbreviations RuBisCo, rubisco, RuBPCase, or RuBPco, is an enzyme () involved in the first major step of carbon fixation, a process by which atmospheric carbon dioxide is converted by plants and other photosynthesis, photosynthetic organisms to fuel, energy-rich molecules such as glucose. In chemical terms, it catalysis, catalyzes the carboxylation of ribulose-1,5-bisphosphate (also known as RuBP). It is probably the most abundant enzyme on Earth. Alternative carbon fixation pathways RuBisCO is important biology, biologically because it catalyzes the primary chemical reaction by which Total inorganic carbon, inorganic carbon enters the biosphere. While many autotrophic bacteria and archaea fix carbon via the reductive acetyl CoA Pathway, reductive acetyl CoA pathway, the 3-hydroxypropionate cycle, or the reverse Krebs cycle, these pathways are relatively small contributors to global carbon fixation compared t ...

Brian Mathew
Brian Frederick Mathew MBE, VMH is a British botanist, born in the village of Limpsfield, Surrey, England. His particular area of expertise is bulbous plants, particularly ornamental bulbous plants, although he has contributed to other fields of taxonomy and horticulture. He has authored or co-authored many books on bulbs and bulbous genera which appeal to both botanists and gardeners, as well as specialist monographs on other genera, including ''Daphne'' (with Chris Brickell), ''Lewisia'', and ''Helleborus''. His work has been recognized by the British Royal Horticultural Society and the International Bulb Society. Biography Brian Mathew was born in Limpsfield, a village in Surrey, England. His parents encouraged both Brian and his sister to look after small garden plots allocated to them.

Christian Gottlieb Ludwig (30 April 1709 – 7 May 1773) was a German physician and botanist born in Brieg, Silesia (now Brzeg, Poland). He was the father of physician/naturalist Christian Friedrich Ludwig (1757–1823) and of Christian L. Ludwig (1749–1784), a physician/scientist known for his translation of Joseph Priestley's scientific experiments. From 1728 he studied medicine and botany at the University of Leipzig, but due to lack of funds was forced to discontinue his studies, therefore taking a job as a botanist on an African expedition under the leadership of Johann Ernst Hebenstreit (1703–1757).

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
