Anabaena Hoshiarpurensis
''Anabaena'' is a genus of filamentous cyanobacteria that exist as plankton. They are known for nitrogen-fixing abilities, and they form symbiotic relationships with certain plants, such as the mosquito fern. They are one of four genera of cyanobacteria that produce neurotoxins, which are harmful to local wildlife, as well as farm animals and pets. Production of these neurotoxins is assumed to be an input into its symbiotic relationships, protecting the plant from grazing pressure. A DNA sequencing project was undertaken by the United States Department of Energy between 1999 and 2005. This project mapped the complete genome of model organism ''Anabaena variabilis'' ATCC 29413, which is 7.2 million base pairs long. A paper detailing the process was published in 2014. The study focused on heterocysts, which convert nitrogen into ammonia. Certain species of ''Anabaena'' have been used on rice paddy fields, proving to be an effective natural fertilizer.

Adrien-Henri De Jussieu
Adrien-Henri de Jussieu (23 December 1797 – 29 June 1853) was a French botanist. Born in Paris as the son of botanist Antoine Laurent de Jussieu, he received the degree of Doctor of Medicine in 1824 with a treatise of the plant family Euphorbiaceae. When his father retired in 1826, he succeeded him at the Jardin des Plantes; in 1845 he became professor of organography of plants. He was also president of the French Academy of Sciences. De Jussieu was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1850. His main publications were the ''Cours élémentaire de botanique'' (Paris) and the ''Géographie botanique'' (Paris, 1846), as well as several monographs, most notably the one on the family Malpighiaceae. In botanical references, he is usually abbreviated as Adr. Juss., also sometimes as A. Juss., as his father already has the abbreviation Juss. The asteroid 9470 Jussieu was named in honor of the de Jussieu family. In 1825, the French bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
