Hosta (/ ˈhɒstə /, [5] syn. Funkia) is a genus of plants commonly known as hostas, plantain lilies and occasionally by the Japanese name gibōshi. Hostas are widely cultivated as shade-tolerant foliage plants. The genus is currently placed in the family Asparagaceae, subfamily Agavoideae, [6] and is native to northeast Asia (China, Japan ...
Host (biology) The black rat is a reservoir host for bubonic plague. The rat fleas that infest the rats are vectors for the disease. In biology and medicine, a host is a larger organism that harbours a smaller organism; [ 1 ] whether a parasitic, a mutualistic, or a commensalist guest (symbiont). The guest is typically provided with nourishment ...
Plants and algae that grow on the host plant, using it as an attachment point are given the designation epiphytic (epilithic is the name given to plants/algae that use rocks or boulders for attachment), while not necessarily parasitic, some species occur in high correlation with a certain host species, suggesting that they rely on the host ...
Plant defense against herbivory or host-plant resistance (HPR) is a range of adaptations evolved by plants which improve their survival and reproduction by reducing the impact of herbivores. Many plants produce secondary metabolites, known as allelochemicals, that influence the behavior, growth, or survival of herbivores.
Mistletoe is the common name for obligate hemiparasitic plants in the order Santalales. They are attached to their host tree or shrub by a structure called the haustorium, through which they extract water and nutrients from the host plant. The name mistletoe originally referred to the species Viscum album (European mistletoe, of the family ...
Plant pathology or phytopathology is the scientific study of plant diseases caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Plant pathology involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance ...
Boquila trifoliolata is the only plant known to engage in mimetic polymorphism, meaning it can mimic the leaves of multiple host plants. [ 4 ] [ 17 ] Other species of vines are capable of limited crypsis for one host species, but B. trifoliata is notable since it can mimic the leaves of multiple species, with one vine capable of simultaneously ...
Relative to a susceptible plant, disease resistance is the reduction of pathogen growth on or in the plant (and hence a reduction of disease), while the term disease tolerance describes plants that exhibit little disease damage despite substantial pathogen levels. Disease outcome is determined by the three-way interaction of the pathogen, the ...
