Planon
Planon is a Dutch enterprise software company founded in 1982 that develops integrated workplace management system software for corporate real estate, facilities, maintenance, and sustainability management.
Planorbarius corneus
Planorbarius corneus, the great ramshorn, is a large air-breathing freshwater snail of the Planorbidae with a left-coiling shell, native from Western Europe to Siberia and the Middle East.
Planova
Planova is a brand of virus removal filters made by Asahi Kasei Medical, launched in 1989 as the world's first filter for virus removal in biotherapeutics manufacturing.
planqc
planqc is a German quantum computing company in Garching near Munich, founded in 2022 by physicists from the Max Planck Institute of Quantum Optics to build neutral-atom quantum computers.
PlanRadar
PlanRadar is a Vienna-based software company founded in 2013 that sells cloud-based field management software for documentation and task management on construction and real estate projects.
PLANSEE
PLANSEE is a privately held Austrian group making tungsten and molybdenum components by powder metallurgy, founded in 1921 in Tyrol by Paul Schwarzkopf and Richard Kurtz.
Plant
Plant (Plantae): photosynthetic eukaryotes, from land plants to broadly defined Archaeplastida; fungi and most algae excluded. Covers classification, evolution, 335,497 flowering species, uses, and extinction risk.
Plant and fungal small nucleolar RNAs
Small nucleolar RNAs in plants and fungi are short non-coding RNAs guiding rRNA modification, organized as polycistronic clusters in plants and mixed arrangements in fungi, unlike mainly intronic vertebrate snoRNAs.
Plant and metazoan subtilases
Plant and metazoan subtilases are subtilisin-like serine proteases of the MEROPS S8 family outside the bacterial subtilisins and mammalian proprotein convertases, including plant SBTs, caspase-like phytaspases, and site-1 protease.
Plant aspartyl proteases
Plant aspartyl proteases (aspartic proteases, EC 3.4.23) are acidic-pH endopeptidases with two catalytic aspartates and a saposin-like plant-specific insert; found in seeds, flowers, and leaves, they drive plant defense, development, and cardoon rennet for cheesemaking.
Plant Bowen
Plant Bowen is a coal-fired power station in Bartow County, Georgia, near Cartersville, owned by Georgia Power, with four coal-fired units of 3,376 MW that began operation between 1971 and 1975.
Plant breeding
Plant breeding: the science of changing plant genetics for better crops, spanning selection, hybridization, genomic selection, and genome editing, from the Green Revolution to the EU's 2026 NGT regulation.
Plant cell
A plant cell is a eukaryotic cell that builds plant tissues, distinguished from animal cells by a cellulose cell wall, chloroplasts that carry out photosynthesis, and a large central vacuole.
Plant community
Plant community: an assemblage of plant species co-occurring at a site, studied through community assembly (dispersal, filtering, competition) and classified by floristic composition via phytosociology, EcoVeg, and national typologies such as NSW plant community types.
Plant Conservatory
Plant Conservatory, Bulbuley, Gangtok, Sikkim, India: a Forest Department botanical conservation site inaugurated in 2015, holding a rhododendron gene pool, orchid greenhouses, and over 400 plant species in Bulbuley Reserve Forest.
Plant Development
Plant development: the gene-, hormone-, and timing-driven transformation of plants through maturity stages. Continuous meristem-based growth, phytohormone crosstalk (auxin, cytokinin, gibberellin), and environmental sensitivity distinguish it from animal development.
Plant disease
Plant disease: interference with normal plant functions by biotic pathogens (fungi, bacteria, viruses, nematodes) or abiotic agents; causes global crop yield losses of 17–30% and is managed through Integrated Pest Management.
Plant disease resistance
Plant disease resistance, also called plant immunity, is the heritable capacity of a plant to limit damage from pathogens like fungi, bacteria, and viruses, underpinning crop resistance breeding.
Plant disease types
Plant disease types are the broad categories into which infectious plant diseases are grouped, by causal organism (fungi, bacteria, viruses) or by appearance, including rusts, mildews, and blights.
Plant ecology
Plant ecology: the study of plants' relationships with their environment at organism, population, community, and biome levels. Founded in late 19th-century Germany and Scandinavia; covers competition, facilitation, succession, and global-change impacts on plant communities.
Plant Evolution Garden
Plant Evolution Garden (גינת האבולוציה של הצמח), a free open-air garden at the Hebrew University's Edmond J. Safra Campus, Givat Ram, Jerusalem, presenting 500 million years of plant evolution in five stages as part of the Nature Park & Galleries museum.
Plant hormone
Plant hormones (phytohormones) are low-concentration plant signaling molecules; ten groups including auxin, gibberellins, cytokinins, ABA, ethylene, salicylates, jasmonates, brassinosteroids, strigolactones, and peptide hormones regulate growth and stress via crosstalk.
Plant iron nutrition
Plant iron nutrition is the set of mechanisms by which plants acquire iron from soil, where it is abundant but poorly soluble, using Strategy I and Strategy II uptake.
Plant life
Plant life: plants in general, of all types; synonymous in scope with vegetation (plant cover of an area) and flora (species of a region). Over 300,000 catalogued species; produce 80% of breathable oxygen.
Plant milk
Plant milk (plant-based milk alternative, nondairy milk, 植物性ミルク) is a beverage of legumes, cereals, nuts, or seeds extracted in water as a dairy substitute; soy, almond, oat, coconut, and rice types differ in protein, fortification, environmental footprint, and naming rules.
Plant molecular biology
Plant molecular biology: study of gene, protein, and metabolite function and regulation in plants; grew from 1970s recombinant DNA tools; journals Plant Molecular Biology (1981) and The Plant Cell (1989); applications in CRISPR crop improvement and molecular farming.
Plant nursery
Plant nursery: an establishment propagating and growing plants for sale or transplanting, also called nursery stock production. Covers field, container, and greenhouse systems, plant health certification (SANC, EU plant passport), and forest seedling supply.
Plant nutrition
Plant nutrition: the study of the 14 essential elements plants need, six macronutrients (N, P, S, K, Ca, Mg) and micronutrients, their functions, deficiency symptoms, sensing, and fertilizer management.
Plant oils/blackcurrant bud oil
Plant oils/blackcurrant bud oil, EU pesticide active substance ID 295 (ribes nigrum L. bud oil), is an unapproved antimicrobial essential oil from blackcurrant flower buds, rich in 3-carene and sabinene, also a perfumery absolute.
