Phytophthora Cryptogea
''Phytophthora cryptogea'' is a species of Oomycete, water mould in the family Pythiaceae. It is a plant pathology, plant pathogen that infects several species of cultivated plants, including over 40 species of cultivated flowers.Olson, H. A., et al. (2011)Phylogenetic history of ''Phytophthora cryptogea'' and ''P. drechsleri'' isolates from floriculture crops in North Carolina greenhouses.''Phytopathology'' 101(11) 1373-84. It was first described as the cause of tomato foot rot in tomatoes Host Range and Symptoms This species is reported to be pathogenic on Petunia × atkinsiana, grandiflora petunia (''Petunia'' × ''atkinsiana''). It causes root rot, shoot rot and shanking in tulips. It also infects blue daze (''Evolvulus glomeratus''), dusty miller (''Jacobaea maritima''), Barberton daisy (''Gerbera jamesonii''), and garden verbena (Verbena × hybrida, ''Verbena'' × ''hybrida'').

Verbena
''Verbena'' (), also known as vervain or verveine, is a genus in the family Verbenaceae. It contains about 150 species of annual and perennial herbaceous or semi-woody flowering plants. The majority of the species are native to the Americas and Asia; however, ''Verbena officinalis'', the common vervain or common verbena, is the type species and native to Europe. Naming In English, the name ''Verbena'' is usually used in the United States and the United Kingdom, whereas elsewhere the terms ''verveine'' or ''vervain'' are in use. When used alone, the terms usually refer to common verbena. Description Verbena is an herbaceous flowering plant, belonging to the Verbenaceae family, and may be annual or perennial depending on the species. The leaves are usually opposite, simple, and in many species hairy, often densely so. The flowers are small, with five petals, and borne in dense spikes. Typically some shade of blue, they may also be white, pink, or purple, especially in cultivars ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytophthora
''Phytophthora'' (from Greek language, Greek (''phytón''), "plant" and (), "destruction"; "the plant-destroyer") is a genus of plant-damaging oomycetes (water molds), whose member species are capable of causing enormous economic losses on crops worldwide, as well as environmental degradation, environmental damage in natural ecosystems. As well as impacting large scale agriculture, ''Phytophthora'' is a nuisance to garden and indoor plant hobbyists as well as bonsai artists. The cell wall of ''Phytophthora'' is made up of cellulose. The genus was first described by Anton de Bary, Heinrich Anton de Bary in 1875. Approximately 170 species have been described, although 100–500 undiscovered ''Phytophthora'' species are estimated to exist. Pathogenicity ''Phytophthora'' species, spp. are mostly pathogens of dicotyledons, and many are relatively host-specific parasites. ''Phytophthora cinnamomi'', though, infects thousands of species ranging from club mosses, ferns, cycads, coni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Castanea Sativa
''Castanea sativa'', the sweet chestnut, Spanish chestnut or just chestnut, is a species of tree in the family Fagaceae, native to Southern Europe and Asia Minor, and widely cultivated throughout the temperate world. A substantial, long-lived deciduous tree, it produces an edible seed, the chestnut, which has been used in cooking since ancient times. Description ''C. sativa'' attains a height of with a trunk often in diameter. Around 20 trees are recorded with diameters over including one in diameter at breast height. A famous ancient tree known as the Hundred Horse Chestnut in Sicily was historically recorded at in diameter (although it has split into multiple trunks above ground). The bark often has a net-shaped (retiform) pattern with deep furrows or fissures running spirally in both directions up the trunk. The trunk is mostly straight with branching starting at low heights. The oblong-lanceolate, boldly toothed leaves are long and broad. The flowers of both sexe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
