Fergusonina Microcera
''Fergusonina'', the sole genus in the family of Fergusoninidae, are gall-forming flies. There are about 40 species in the genus, all of them producing galls on ''Eucalyptus'', ''Melaleuca'', ''Corymbia'', and ''Metrosideros'' species (all in the family Myrtaceae) in Australia and New Zealand. These flies are small and their larvae grow within galls formed on the leaf, shoot or flower buds. The galls themselves are induced by endosymbiotic nematodes in the genus '' Fergusobia'' (family Neotylenchidae) which are obligate mutualists of the flies. Females carry the nematode in their haemocoel, and transport them to host plants while laying their eggs. Most of the fly species are specific to their tree hosts but a few use more than one species of host. The taxonomic placement of Fergusoninidae is disputed. While formerly in the superfamily Opomyzoidea, a 2020 study places it within superfamily Nerioidea based on morphology, while a 2021 study using transcriptome data places it in ...

John Russell Malloch
John Russell Malloch (16 November 1875 – 1963) was a Scottish entomologist who specialised in Diptera and Hymenoptera. Malloch was born at Milton of Campsie in Stirlingshire, Scotland. His widowed father had one son, James Malloch (born 1873) when he married John Russell's mother, Margaret Stirling, on 30 August 1875. He and several others of his family worked at a textile factory in the area, but he spent his spare time collecting insects in the fields. His first published paper (1897) describes a type of migrating butterfly. In 1903 Malloch sold his extensive collection to the Glasgow Museum. He continued to collect, but began to concentrate on Diptera from that time forward. Before emigrating in 1910, he donated the remainder of his collection (13,000 flies) to the Royal Scottish Museum. Little is known about Malloch's education. He listed a university degree from Glasgow on his job applications in the USA, but this has not been verified by university records from that area ...

Eucalyptus
''Eucalyptus'' () is a genus of over seven hundred species of flowering trees, shrubs or mallees in the myrtle family, Myrtaceae. Along with several other genera in the tribe Eucalypteae, including '' Corymbia'', they are commonly known as eucalypts. Plants in the genus ''Eucalyptus'' have bark that is either smooth, fibrous, hard or stringy, leaves with oil glands, and sepals and petals that are fused to form a "cap" or operculum over the stamens. The fruit is a woody capsule commonly referred to as a "gumnut". Most species of ''Eucalyptus'' are native to Australia, and every state and territory has representative species. About three-quarters of Australian forests are eucalypt forests. Wildfire is a feature of the Australian landscape and many eucalypt species are adapted to fire, and resprout after fire or have seeds which survive fire. A few species are native to islands north of Australia and a smaller number are only found outside the continent. Eucalypts have been grow ...

Melaleuca
''Melaleuca'' () is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees (although the last name is also applied to species of '' Leptospermum''). They range in size from small shrubs that rarely grow to more than high, to trees up to . Their flowers generally occur in groups, forming a "head" or "spike" resembling a brush used for cleaning bottles, containing up to 80 individual flowers. Melaleucas are an important food source for nectarivorous insects, birds, and mammals. Many are popular garden plants, either for their attractive flowers or as dense screens and a few have economic value for producing fencing and oils such as "tea tree" oil. Most melaleucas are endemic to Australia, with a few also occurring in Malesia. Seven are endemic to New Caledonia, and one is found only on (Australia's) Lord Howe Island. Melaleucas are found in a wide variety of habitats. Many are adapted for life in swamp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corymbia
''Corymbia'', commonly known as bloodwoods, is a genus of about one hundred species of tree that, along with ''Eucalyptus'', '' Angophora'' and several smaller groups, are referred to as eucalypts. Until 1990, corymbias were included in the genus ''Eucalyptus'' and there is still considerable disagreement among botanists as to whether separating them is valid. As of January 2020, ''Corymbia'' is an accepted name at the Australian Plant Census. Description Eucalypts in the genus ''Corymbia'' are trees, sometimes mallee-like, that either have rough, fibrous or flaky bark, or smooth bark that is shed in small flakes or short strips. Young plants and coppice regrowth have leaves that differ from adult leaves. The adult leaves are arranged alternately (strictly disjunct opposite, but appearing alternate), with oil glands. The flower buds are arranged in groups on a branching peduncle, each branch usually with seven buds, but with the pedicels of differing lengths, so that the inflo ...

Metrosideros
''Metrosideros'' is a genus of approximately 60 trees, shrubs, and vines mostly found in the Pacific region in the family Myrtaceae. Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular. The name derives from the Ancient Greek ''metra'' or "heartwood" and ''sideron'' or "iron". Perhaps the best-known species are the pōhutukawa (''M. excelsa''), northern (''M. robusta'') and southern rātā (''M. umbellata'') of New Zealand, and '' ōhia lehua'' (''M. polymorpha''), from the Hawaiian Islands. Distribution ''Metrosideros'' is one of the most widely spread flowering plant genera in the Pacific. New Caledonia has 21 species of ''Metrosideros'', New Zealand has 12, New Guinea has seven and Hawaii has 5. The genus is present on most other high Pacific Islands, including Solomon Islands, Vanuatu, Fiji, Samoa, Cook islands, French Polynesia, Bonin Islands and Lord Howe Island, but absent from Micronesia . The genus is also represen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myrtaceae
Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous, brightly coloured, and numerous. Evolutionary history Scientists hypothesize that the family Myrtaceae arose between 60 and 56 million years ago (Mya) during the Paleocene era. Pollen fossils have been sourced to the ancient supercontinent Gondwana. The breakup of Gondwana during the Cretaceous period (145 to 66 Mya) geographically isolated disjunct taxa and allowed for rapid speciation; i ...

Opomyzoidea
The Opomyzoidea are a superfamily of flies. Biology Opomyzoids show a range of lifestyles including mining plant leaves (many Agromyzidae), feeding in grass stems ( Anthomyzidae and Opomyzidae), forming plant galls (''Fergusonina''), feeding on fungi (some Anthomyzidae and Asteiidae), feeding on sap flows of trees (some Aulacigastridae, Odiniidae and Periscelididae), living in galleries of wood-boring insects (Odiniidae) or in water-filled cavities of plants (phytotelmata; Aulacigastridae, Neurochaetidae and Periscelididae). However, the biology of most opomyzoid families is poorly known. Phylogeny The phylogeny of Opomyzoidea is controversial, with different authors assigning different families and different relationships among families. One study using molecular analysis concluded that the superfamily is not monophyletic In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancesto ...

Nerioidea
Nerioidea is a superfamily of Acalyptratae flies. Description As flies, Nerioidea undergo complete metamorphosis with the four life stages of egg, larva, pupa and adult. The adult stage has three body segments (head, thorax and abdomen), three pairs of legs and one pair of wings. Some features that distinguish adult Nerioidea from other flies are: a face that's usually weakly sclerotised (except in Fergusoninidae), antenna usually porrect or slightly deflexed (elbowed in Tanypezidae), wing veins R2+3 and R4+5 usually convergent, and the wing anal cell usually much smaller than the subcostal cell. Ecology Most Nerioidea are associated with dead and decaying organic matter such as dead wood, rotting fruit and bat dung. On the other hand, Fergusoninidae form galls in plants of family Myrtaceae, and some Micropezidae The Micropezidae are a moderate-sized family of acalyptrate muscoid flies in the insect order Diptera, comprising about 500 species in about 50 genera and five ...

Transcriptome
The transcriptome is the set of all RNA transcripts, including coding and non-coding, in an individual or a population of cells. The term can also sometimes be used to refer to all RNAs, or just mRNA, depending on the particular experiment. The term ''transcriptome'' is a portmanteau of the words ''transcript'' and ''genome''; it is associated with the process of transcript production during the biological process of transcription. The early stages of transcriptome annotations began with cDNA libraries published in the 1980s. Subsequently, the advent of high-throughput technology led to faster and more efficient ways of obtaining data about the transcriptome. Two biological techniques are used to study the transcriptome, namely DNA microarray, a hybridization-based technique and RNA-seq, a sequence-based approach. RNA-seq is the preferred method and has been the dominant transcriptomics technique since the 2010s. Single-cell transcriptomics allows tracking of transcript changes ...
