Magallana is a genus of true oysters (family Ostreidae) [1] containing some of the most important oysters used for food. Species in this genus have been moved from Crassostrea after it was found to be paraphyletic. [2] [3]
Extant species are: [1]
Species only known from the fossil record: [1]
The genome of Magallana gigas has been recently sequenced [4] revealing an extensive set of genes that enable it to cope with environmental stresses.
Genome projects are scientific endeavours that ultimately aim to determine the complete genome sequence of an organism and to annotate protein-coding genes and other important genome-encoded features. The genome sequence of an organism includes the collective DNA sequences of each chromosome in the organism. For a bacterium containing a single chromosome, a genome project will aim to map the sequence of that chromosome. For the human species, whose genome includes 22 pairs of autosomes and 2 sex chromosomes, a complete genome sequence will involve 46 separate chromosome sequences.
Crassostrea is a genus of true oysters containing some of the most important oysters used for food.
The Ostreidae, the true oysters, include most species of molluscs commonly consumed as oysters. Pearl oysters are not true oysters, and belong to the order Pteriida.
The Pacific oyster, Japanese oyster, or Miyagi oyster is an oyster native to the Pacific coast of Asia. It has become an introduced species in North America, Australia, Europe, and New Zealand.
Sinocyclocheilus is a genus of freshwater fish in the family Cyprinidae that is endemic to Guangxi, Guizhou and Yunnan in China. Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes. Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back, the function of which is unclear. In contrast, the Sinocyclocheilus species that live aboveground, as well as a few found underground, show no clear cavefish adaptions. They are relatively small fish reaching up to 23 cm (9.1 in) in length. The individual species have small ranges and populations, leading to the status of most of the evaluated species as threatened. Many species populations in the genus have yet to be evaluated by the IUCN.
Oreonectes is a genus of fish in the family Nemacheilidae found in the rivers and caves of Asia. Many of these species are troglobitic.
Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China, as well as inland waters of the larger part of central Asia. They can be distinguished from other genera of Nemacheilidae by marked sexual dimorphism, including the development of nuptial tubercles on breeding males. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera, but as Wikipedia follows Fishbase for fish species all but Hedinichthys have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms.
Yunnanilus is a genus of small stone loaches that are endemic to southeastern China, especially Guangxi and Yunnan. They are found in rivers, streams and lakes; some species are restricted to caves.
Rock oysters are true oysters of the genus Saccostrea, belonging to the subfamily Saccostreinae of the family Ostreidae.
The Portuguese oyster is a species of oyster found in the southwest Iberian Peninsula, closely related to the Pacific oyster. Although first identified as a native European species, genetic studies have suggested the Portuguese oyster originated from the Pacific coast of Asia and was introduced to Europe by Portuguese trading ships in the 16th century. The species is usually found in coastal river mouths and estuaries.
SOAP is a suite of bioinformatics software tools from the BGI Bioinformatics department enabling the assembly, alignment, and analysis of next generation DNA sequencing data. It is particularly suited to short read sequencing data.
Solute carrier family 52, member 3, formerly known as chromosome 20 open reading frame 54 and riboflavin transporter 2, is a protein that in humans is encoded by the SLC52A3 gene.
Triticum urartu, also known as red wild einkorn wheat, and a form of einkorn wheat, is a grass species related to wheat, and native to western Asia. It is a diploid species whose genome is the A genome of the allopolyploid hexaploid bread wheat Triticum aestivum, which has genomes AABBDD.
Troglonectes is a genus of troglobitic fish in the family Nemacheilidae, native to caves of Asia. Fishbase and other authorities place these species in the genus Oreonectes.
Magallana bilineata, commonly known as the Philippine cupped oyster or slipper oyster, is an economically important species of true oyster found abundantly in the western Pacific Ocean, from the Philippines to Tonga and Fiji. In 2020 an exotic population was discovered in north-east Australia. They grow attached to hard objects in brackish shallow intertidal or subtidal waters, at depths of 0 to 300 metres. They are cultured extensively in the Philippines, where annual landings can range from 11,700 to 18,300 tons. They are known as talaba or talabang tsinelas in Filipino to distinguish them from talabang kukong kabayo
Bat coronavirus RaTG13 is a SARS-like betacoronavirus identified in the droppings of the horseshoe bat Rhinolophus affinis. It was discovered in 2013 in bat droppings from a mining cave near the town of Tongguan in Mojiang county in Yunnan, China. In February 2020, it was identified as the closest known relative of SARS-CoV-2, the virus that causes COVID-19, sharing 96.1% nucleotide identity. However, in 2022, scientists found three closer matches in bats found 530 km south, in Feuang, Laos, designated as BANAL-52, BANAL-103 and BANAL-236.
The Iwagaki oyster, is an oyster native to Japan. It was first described in 1934.
Phalaenopsis zhejiangensis, also known as 象鼻兰 in Chinese, is a species of orchid native to Thailand and Vietnam. It is firmly established to be within the genus Phalaenopsis. Its extraordinary flowers are white with purple transverse bands on sepals and petals and with purple lip markings. It is a typical epiphytic orchid. It is found at elevations of 300 to 900 m. The specific epithet zhejiangensis refers to this species origin in the Chinese province of Zhejiang. It is closely related to Phalaenopsis wilsonii.
