Lucy Moore (botanist)
Lucy Beatrice Moore (14 July 1906 – 9 June 1987) was a New Zealand botanist and ecologist. Biography Early life and education Moore was born in Warkworth, New Zealand, Warkworth, New Zealand, on 14 July 1906, the daughter of Janet Morison and Harry Blomfield Moore. Her father was a local librarian and keen amateur naturalist. She went to primary school at Warkworth, New Zealand, Warkworth and then left home to attend Epsom Girls' Grammar School, Epsom Girls' Grammar school in Auckland. She won both a Junior and a Senior National Scholarship at Epsom Girls' as well as a University National Scholarship after enrolling as a student at University of Auckland, Auckland University College in 1925. Moore graduated MSc with first-class honours in 1929 under the direction of the botanist T. L. Lancaster. Her thesis was on the root parasite ''Dactylanthus taylorii, Dactylanthus''. Career Moore was at first unsuccessful in her attempt to work as a botanist. She applied for but failed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Didynamous
The stamen (: stamina or stamens) is the pollen-producing reproductive organ of a flower. Collectively, the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains microsporangia. Most commonly anthers are two-lobed (each lobe is termed a locule) and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The size of anthers differs greatly, from a tiny fraction of a millimeter in ''Wolfia'' spp up to five inches (13 centimeters) in ''Canna iridiflora'' and ''Strelitzia nicolai''. The stamens in a flower are collectively called the androecium. The androecium can con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amplified Fragment Length Polymorphism
AFLP-PCR or just AFLP is a PCR-based tool used in genetics research, DNA fingerprinting, and in the practice of genetic engineering. Developed in the early 1990s by KeyGene, AFLP uses restriction enzymes to digest genomic DNA, followed by ligation of adaptors to the sticky ends of the restriction fragments. A subset of the restriction fragments is then selected to be amplified. This selection is achieved by using primers complementary to the adaptor sequence, the restriction site sequence and a few nucleotides inside the restriction site fragments (as described in detail below). The amplified fragments are separated and visualized on denaturing on agarose gel electrophoresis , either through autoradiography or fluorescence methodologies, or via automated capillary sequencing instruments. Although AFLP should not be used as an acronym, it is commonly referred to as "Amplified fragment length polymorphism". However, the resulting data are not scored as length polymorphisms, but ...

Ourisia Calycina
''Ourisia calycina'' is a species of flowering plant in the family Plantaginaceae that is endemic to the South Island of New Zealand and was described by William Colenso in 1889. Plants of this species are showy, perennial, large-leaved, tufted, rhizomatous herbs that are mostly glabrous (hairless) or with some non-glandular hairs. They have broadly ovate leaves. The flowers are in whorls in each node, with a regular calyx, a large, white irregular corolla, and fruits up to 1 cm long. The corolla tube is yellow with three lines of yellow hairs inside. It is listed as Not Threatened. Taxonomy ''Ourisia calycina'' Colenso is in the plant family Plantaginaceae. William Colenso described ''O. calycina'' in 1889. The type material was collected by William Colenso from the Waimakariri River near Bealey, South Island, New Zealand. The holotype is housed at the herbarium at the Royal Botanical Gardens, Kew (K000979335). ''Ourisia calycina'' plants are large and showy perennial ...

Chloroplast DNA
Chloroplast DNA (cpDNA) is the DNA located in chloroplasts, which are photosynthetic organelles located within the cells of some eukaryotic organisms. Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus. The existence of chloroplast DNA was identified biochemically in 1959, and confirmed by electron microscopy in 1962. The discoveries that the chloroplast contains ribosomes and performs protein synthesis revealed that the chloroplast is genetically semi-autonomous. The first complete chloroplast genome sequences were published in 1986, ''Nicotiana tabacum'' (tobacco) by Sugiura and colleagues and ''Marchantia polymorpha'' (liverwort) by Ozeki et al. Since then, a great number of chloroplast DNAs from various species have been sequenced. Molecular structure Chloroplast DNAs are circular, and are typically 120,000–170,000 base pairs long. They can have a contour length of around 30–60 micrometers, and have a mass of about 80 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ribosomal DNA
Ribosomal DNA (rDNA) is a DNA sequence that codes for ribosomal RNA. These sequences regulate transcription initiation and amplification, and contain both transcribed and non-transcribed spacer segments. In the human genome there are 5 chromosomes with nucleolus organizer regions: the acrocentric chromosomes 13 (RNR1), 14 ( RNR2), 15 ( RNR3), 21 (RNR4) and 22 (RNR5). The genes that are responsible for encoding the various sub-units of rRNA are located across multiple chromosomes in humans. But the genes that encode for rRNA are highly conserved across the domains, with only the copy numbers involved for the genes having varying numbers per species. In Bacteria, Archaea, and chloroplasts the rRNA is composed of different (smaller) units, the large (23S) ribosomal RNA, 16S ribosomal RNA and 5S rRNA. The 16S rRNA is widely used for phylogenetic studies. Eukaryotes The rRNA transcribed from the approximately 600 rDNA repeats forms the most abundant section of RNA found in cells ...

Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, Protein, protein Amino acid, amino acid sequences, or Morphology (biology), morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaimanawa Range
The Kaimanawa Range of mountains (often known as the ''Kaimanawas'') is located in the central North Island of New Zealand. They extend for 50 kilometres in a northeast/southwest direction through largely uninhabited country to the south of Lake Taupō, east of the "Desert Road". Their slopes form part of the North Island Volcanic Plateau. The New Zealand Ministry for Culture and Heritage gives a translation of "breath for food" for ''Kaimanawa''. The lands around the mountains are scrubby. To the west, where the Rangipo Desert is located, the soils are poor quality. To the east, the soils are more fertile, but the land is very rough. A feral horse, the Kaimanawa horse. roams free on the ranges. Unlike the majority of mountain ranges in New Zealand, the Kaimanawa Range is divided into private land. Considerable areas of the Rangipo Desert are used by the New Zealand Army for training. Demographics Kaimanawa covers and had an estimated population of as of with a population den ...
