Salvinia Nuriana
''Salvinia'' or watermosses is a genus of free-floating aquatic ferns in the family Salviniaceae. The genus is named in honor of 17th-century Italian naturalist Anton Maria Salvini, and the generic name was first published in 1754 by French botanist Jean-François Séguier in ''Plantae Veronenses'', a description of the plants found around Verona. Twelve species are recognized, at least three of which (''S. molesta'', ''S. herzogii'', and ''S. minima'') are believed to be hybrids in part because their sporangia are found to be empty. ''Salvinia'' is related to the other water ferns, including the mosquito fern ''Azolla''. Recent sources include both ''Azolla'' and ''Salvinia'' in Salviniaceae, although each genus was formerly given its own family. ''Salvinia'', like the other ferns in order Salviniales, are heterosporous, producing spores of differing sizes. However, leaf development in ''Salvinia'' is unique. The upper side of the floating leaf, which appears to face the ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-François Séguier
Jean-François Séguier (; 25 November 1703 – 1 September 1784) was a French archaeologist, epigraphist, astronomer and botanist from Nîmes. He studied law in Montpellier Montpellier (; ) is a city in southern France near the Mediterranean Sea. One of the largest urban centres in the region of Occitania (administrative region), Occitania, Montpellier is the prefecture of the Departments of France, department of ..., during which time, he developed a passion for botany. He was a friend and collaborator to Scipio Maffei, with whom he took an extended scientific tour throughout Europe (1732–36). In 1755 he became a member of the Académie de Nîmes, serving as its ''secrétaire perpétuel'' from 1765 to 1784. In 1772 he became a member of the Académie royale des Inscriptions et Belles-Lettres. The plant genus '' Seguieria'' (family Petiveriaceae, Loefl., 1758) commemorates his name, as do the botanical species ''Ranunculus seguieri'' ( Vill., 1779), ''Euphorbia segui ...

Spores
In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. They were thought to have appeared as early as the mid-late Ordovician period as an adaptation of early land plants. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. In some rare cases, a diploid spore is also produced in some algae, or fungi. Under favourable conditions, the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salvinia Oblongifolia
''Salvinia oblongifolia'' is a species of plant in the Salviniaceae. Its leaves can grow with up to 6 cm long and 2.5 cm wide, making it the largest species in the genus ''Salvinia''''.'' Leaves are rectangular and approximately three times as long as wide with short blunt papillae that are arranged in double rows on the upper leaf surface, which make for easy identification.Riefner, Richard E., and Alan R.

Salvinia Molesta
''Salvinia molesta'', commonly known as giant salvinia, or as kariba weed after it infested a large portion of Lake Kariba between Zimbabwe and Zambia, is an aquatic fern, native to south-eastern Brazil. It is a free-floating plant that does not attach to the soil, but instead remains buoyant on the surface of a body of water. The fronds are long and broad, with a bristly surface caused by the hair-like strands that join at the end to form eggbeater shapes. They are used to provide a waterproof covering. These fronds are produced in pairs also with a third modified root-like frond that hangs in the water. It has been accidentally introduced or escaped to countless lakes throughout the United States, including Caddo Lake in Texas, where the invasive species has done extensive damage, killing off other life. In Europe, ''Salvinia molesta'' has been included since 2019 in the List of invasive alien species of Union concern (the Union list). This implies that this species ...

GenBank
The GenBank sequence database is an open access, annotated collection of all publicly available nucleotide sequences and their protein translations. It is produced and maintained by the National Center for Biotechnology Information (NCBI; a part of the National Institutes of Health in the United States) as part of the International Nucleotide Sequence Database Collaboration (INSDC). In October 2024, GenBank contained 34 trillion base pairs from over 4.7 billion nucleotide sequences and more than 580,000 formally described species. The database started in 1982 by Walter Goad and Los Alamos National Laboratory. GenBank has become an important database for research in biological fields and has grown in recent years at an exponential rate by doubling roughly every 18 months. GenBank is built by direct submissions from individual laboratories, as well as from bulk submissions from large-scale sequencing centers. Submissions Only original sequences can be submitted to GenBank. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
