Mycorrhiza in the context of Beneficial weed

Mutualism describes the ecological interaction between two or more species where each species has a net benefit. Mutualism is a common type of ecological interaction. Prominent examples are:

• the nutrient exchange between vascular plants and mycorrhizal fungi,
• the fertilization of flowering plants by pollinators,
• the ways plants use fruits and edible seeds to encourage animal aid in seed dispersal, and
• the way corals become photosynthetic with the help of the microorganism zooxanthellae.

Mutualism can be contrasted with interspecific competition, in which each species experiences reduced fitness, and exploitation, and with parasitism, in which one species benefits at the expense of the other. However, mutualism may evolve from interactions that began with imbalanced benefits, such as parasitism.

The Journal of Ecology is a bimonthly peer-reviewed scientific journal covering all aspects of the ecology of plants. It was established in 1913 and is published by Wiley-Blackwell on behalf of the British Ecological Society.

The journal publishes papers on plant ecology (including algae) in both terrestrial and aquatic ecosystems. In addition to population and community ecology, articles on biogeochemistry, ecosystems, microbial ecology, physiological plant ecology, climate change, molecular genetics, mycorrhizal ecology, and the interactions between plants and organisms such as animals or bacteria, are published regularly. Besides primary research articles, it publishes "Essay Reviews" and "Forum" articles. In 2008, the first papers in a new series called "Future Directions" were published. These short papers are intended to stimulate debate as to where a field within plant ecology is going, or needs to go.

An arbuscular mycorrhiza (AM) (plural mycorrhizae) is a type of mycorrhiza in which the symbiont fungus (Arbuscular mycorrhizal fungi, or AMF) penetrates the cortical cells of the roots of a vascular plant forming arbuscules. Arbuscular mycorrhiza is a type of endomycorrhiza along with ericoid mycorrhiza and orchid mycorrhiza (not to be confused with ectomycorrhiza). They are characterized by the formation of unique tree-like structures, the arbuscules. In addition, globular storage structures called vesicles are often encountered.

Arbuscular mycorrhizae are formed by fungi in the subphylum Glomeromycotina and some fungi from the Mucoromycotina. These subphyla, along with the Mortierellomycotina, form the phylum Mucoromycota, a sister clade of the more well-known and diverse dikaryan fungi.

Cantharellus is a genus of mushrooms, commonly known as chanterelles (/ˌʃæntəˈrɛl/), a name which can also refer to the type species, Cantharellus cibarius. They are mycorrhizal fungi, meaning they form symbiotic associations with plants. Chanterelles may resemble a number of other species, some of which are poisonous.

The name comes from the Greek word kantharos ('tankard, cup'). Chanterelles are one of the most recognized and harvested groups of edible mushrooms.

Lactarius subdulcis, commonly known as the mild milkcap or beech milk cap, is an edible mushroom in the genus Lactarius. It is brown in colour, with a large number of gills and a particularly thin layer of flesh in the cap.

Mycorrhizal, the mushroom is found from late summer to late autumn at the base of beech trees in small groups or individually, where it is one of the two most common species of fungi. Alternatively, it can be found in large groups in fields, sometimes with more than a hundred individual mushrooms. It is found in Europe, and, despite previous research to the contrary, is absent in North America.

Tussock grasses (also known as bunch grasses or hummock grasses) are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens.

Many species have long roots that may reach two meters (6+1⁄2 feet) or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists.

Root hairs or absorbent hairs, are outgrowths of epidermal cells, specialized cells at the tip of a plant root. They are lateral extensions of a single cell and are only rarely branched. They are found in the region of maturation, of the root. Root hair cells improve plant water absorption by increasing root surface area to volume ratio which allows the root hair cell to take in more water. The large vacuole inside root hair cells makes this intake much more efficient. Root hairs are also important for nutrient uptake as they are main interface between plants and mycorrhizal fungi.
