A transmissible cancer is a cancer cell or cluster of cancer cells that can be transferred between individuals without the involvement of an infectious agent such as an oncovirus. [ 1 ] [ 2 ] The evolution of transmissible cancer has occurred naturally in other animal species, but human cancer transmission is rare. [ 2 ]
Sutherlandia frutescens (cancer bush, [2] balloon pea, Cape Blader Pea, sutherlandia, phetola ("it changes") in seTswana, and insiswa ("the one that drives away the darkness") in isiZulu; syn. Colutea frutescens L., Lessertia frutescens (L.) Goldblatt & J.C.Manning) is a southern African legume in the Sweet Pea Family (Papilionaceae).
Bloodroot is one of many plants whose seeds are spread by ants, a process called myrmecochory. The seeds have a fleshy organ called an elaiosome that attracts ants. The ants take the seeds to their nest, where they eat the elaiosomes, and put the seeds in their nest debris, where they are protected until they germinate.
Orobanche uniflora, commonly known as one-flowered broomrape, [1] one-flowered cancer root, [2] ghost pipe [3] or naked broomrape, [4] is an annual [5] [6] parasitic herbaceous plant. It is native to much of North America, where it is a parasitic plant , tapping nutrients from many other species of plants, including those in the families ...
Commensalism is an interaction in which one species benefits and the other species is unaffected. Epiphytes (plants growing on other plants, usually trees) have a commensal relationship with their host plant because the epiphyte benefits in some way ( e.g. , by escaping competition with terrestrial plants or by gaining greater access to ...
Food biodiversity is defined as "the diversity of plants, animals and other organisms used for food, covering the genetic resources within species, between species and provided by ecosystems." [ 1 ] Food biodiversity can be considered from two main perspectives: production and consumption.
Its chemical emissions, shady canopy, and thick litter inhibit other plant species from establishing themselves – with the occasional exception of plants which support rare butterflies. Herb and tree seedling growth may be inhibited even after bracken is removed, apparently because active plant toxins remain in the soil.
Epidemiology is the study of factors affecting the outbreak and spread of infectious diseases. [10] A disease triangle describes the basic factors required for plant diseases. These are the host plant, the pathogen, and the environment. Any one of these can be modified to control a disease. [11]
