plant : any of a kingdom (Plantae) of multicellular eukaryotic mostly photosynthetic organisms typically lacking locomotive movement or obvious nervous or sensory organs and possessing cellulose cell walls — Webster
Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae. The term is today generally limited to the green plants, which form an unranked clade Viridiplantae (Latin for “green plants”). This includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae, and excludes the red and brown algae. Historically, plants formed one of two kingdoms covering all living things that were not animals, and both algae and fungi were treated as plants; however all current definitions of “plant” exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria).
Green plants have cell walls containing cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts, derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce normal amounts of chlorophyll or to photosynthesize. Plants are characterized by sexual reproduction and alternation of generations, although asexual reproduction is also common. — Wikipedia

Lab-made hormone may reveal secret lives of plants
on January 22, 2018 at 8:06 pm
A new synthetic hormone promises to tease apart the many different roles of the plant hormone auxin and could lead to a new way to ripen fruit. […]
A race against pine: Wood-boring wasp in North...

Invasive species have diverse impacts in different locations, including biodiversity loss, as a result of native species being outcompeted for similar resources. A US research team studied the case of an aggressive Eurasian woodwasp that has recently established in North America and poses a threat to a native competitor species. […]

Plant researchers have tested newly developed wheat lines with improved resistance in field trials. They have demonstrated that a combination of two variations of a resistance gene provides wheat with better protection against the fungal disease. […]
Breakthrough study shows how plants sense the...

Plants lack eyes and ears, but they can still see, hear, smell and respond to environmental cues and dangers. They do this with the aid of hundreds of membrane proteins that sense microbes or other stresses. Researchers now have created the first network map for 200 of these proteins. The map shows how a few key proteins act as master nodes critical for network integrity, and the map also reveals unknown interactions. […]
