Phyllostachys
Phyllostachys (刚竹属) is a genus of running woody bamboos in Poaceae, native from the Himalaya to southern China and Taiwan, with two branches per node and leptomorph rhizomes; economically important for Moso bamboo, timber, pulp, and shoots, and regulated as invasive running bamboo in parts of North America.
Phyllostachys edulis
Phyllostachys edulis, moso bamboo (毛竹, maozhu; Japanese 孟宗竹), a large temperate running bamboo native to central and southern China and Taiwan; synonyms P. pubescens and P. heterocycla; China's most important bamboo, ~4.43 million ha, grown for edible shoots and timber culms.
Phyllosticta
Phyllosticta (formerly Guignardia for the sexual morph) is a genus of Dothideomycete fungi in Phyllostictaceae, ranging from endophytes like P. capitalensis to major crop pathogens causing citrus black spot (P. citricarpa) and grapevine black rot (P. ampelicida).
Phyllostomidae
Phyllostomidae, the New World leaf-nosed bats, is a bat family ranging from the southwestern United States to South America, with the widest diet range of any mammal family.
Phyllostomus
Phyllostomus (spear-nosed bats) is a genus of four Neotropical leaf-nosed bat species in Phyllostomidae, type species the greater spear-nosed bat P. hastatus, established by Lacépède in 1799.
Phyllotaxis
Phyllotaxis: the regular arrangement of leaves, flowers, and scales around a plant stem, most commonly in Fibonacci spirals at the 137.5° golden angle, generated by auxin transport at the shoot apical meristem.
Phyllotis
Phyllotis (leaf-eared mice) is a genus of South American sigmodontine rodents, Waterhouse 1837, type species P. darwini, about 13 species from Ecuador to southern Argentina, including the high-altitude P. vaccarum recorded at 6,739 m.
Phylloxera
Phylloxera (Daktulosphaira vitifoliae, formerly Phylloxera vastatrix) is a North American root-feeding aphid-like insect that reached France in the 1860s, destroyed about 40% of French vines, and is controlled by grafting Vitis vinifera onto resistant American rootstocks.
Phylloxera crisis in Hungary
The phylloxera crisis in Hungary (filoxéravész) was the destruction of over 40% of Hungarian vineyards by the phylloxera aphid between 1875 and the mid-1890s, forcing replanting on American rootstocks.
Phylogenetic footprinting
Phylogenetic footprinting is a comparative genomics method that identifies candidate regulatory elements, such as transcription factor binding sites, by finding unusually well-conserved motifs in orthologous noncoding DNA from related species.
Phylogenetic tree
Phylogenetic tree: branching diagram of evolutionary relationships among species or genes; built by distance, parsimony, maximum likelihood, or Bayesian methods; gene trees can differ from species trees via incomplete lineage sorting.
Phylogenetic tree reconciliation
Phylogenetic tree reconciliation is a computational method that maps a gene tree onto a species tree, explaining their differences by postulating duplication, loss, and horizontal transfer events.
Phylogenetics
Phylogenetics, also known as phylogenetic analysis or tree thinking, is the study of evolutionary relationships among species and genes, depicted as branching phylogenetic trees from common ancestors.
Phylon
Phylon is a peer-reviewed journal of race and culture founded by W. E. B. Du Bois at Atlanta University in 1940 and published today by Clark Atlanta University.
Phylum
Phylum (plural phyla) is a Linnaean taxonomic rank between kingdom and class, grouping organisms by shared body plan, e.g. Chordata and Mollusca; also called division in botany and mycology.
Phymatoceras
Phymatoceras Hyatt, 1867 is an extinct Toarcian (Early Jurassic) ammonite genus in the family Phymatoceratidae, type species P. robustum, pandemic in distribution, ancestor-linked to Hildaites and Dumortieria.
Phymatocerotaceae
Phymatocerotaceae is a family of hornworts whose only genus, Phymatoceros, comprises small thalloid plants known for prolific ventral tubers and a single chloroplast per cell.
Phymatous rosacea
Phymatous rosacea, formerly subtype 3, is rosacea with skin thickening from sebaceous hyperplasia and fibrosis, most often rhinophyma of the nose; it is a diagnostic phenotype treated mainly with surgery and lasers.
Phymaturus
Phymaturus is a genus of viviparous, herbivorous, rock-dwelling liolaemid lizards of Argentina and Chile, split into palluma and patagonicus clades, with dozens of small-ranged species all listed as vulnerable in Argentina.
PHYMI (费莫一科技)
PHYMI (费莫一科技) is a Chinese embodied-AI startup in Shenzhen, founded in 2026 by former Intel and DeepRoute.ai engineer Liu Nianqiu, which raised a nearly USD 100 million seed round led by IDG Capital.
