The rhizosphere is the thin area of soil immediately surrounding the root system. It is a densely populated area in which the roots compete with invading root systems of neighboring plant species for space, water, and mineral nutrients as well as form positive and negative relationships with soil-borne microorganisms such as bacteria, fungi and insects.
Galium aparine is known by a variety of common names in English. They include ' 'sweetheart', 'hitchhikers, cleavers, [2] clivers, bedstraw, (small) goosegrass (not to be confused with other plants known as goosegrass), [2] catchweed, [2] stickyweed, sticky bob, [3] stickybud, stickyback, sticky molly, robin-run-the-hedge, sticky willy, [2] [4] sticky willow, stickyjack, stickeljack, grip ...
Plant seeds exudate a variety of molecules into the spermosphere, [13] and roots exudate into the rhizosphere; these exudates include acids, sugars, polysaccharides and ectoenzymes, and collectively account for 40% of root carbon. [14] Exudation of these compounds has various benefits to the plant and to the microorganisms of the rhizosphere ...
Amongst the green algae especially, the group Volvocales are known to produce exopolysaccharides at a certain point in their life cycle. It occurs in almost all plants, but usually in small amounts. It is frequently associated with substances like tannins and alkaloids. [3] Mucilage has a unique purpose in some carnivorous plants.
Plants which are heterozygous on the waxy gene (Wx:wx) can be characterised by staining the pollen with iodine. Half of the pollen will be blue and half brown whereas the kernels will stay blue (very helpful in backcrossing program). If the plant is homozygous recessive (wx:wx) the whole pollen will be brown and the kernel too.
Ageratina adenophora (synonym Eupatorium adenophorum), commonly known as Crofton weed, is a species of flowering plant in the family Asteraceae native to Mexico and Central America. Originally grown as an ornamental plant, it has become invasive into farmland and bushland worldwide. It is toxic to horses, which develop a respiratory disease ...
Despite the deprivations, Grateful Life beat jail and it gave addicts time to think. Many took the place and its staff as inspiration. They spent their nights filling notebooks with diary entries, essays on passages from the Big Book, drawings of skulls and heroin-is-the-devil poetry.
The ability of the same AM fungi to colonize many species of plants has ecological implications. Plants of different species can be linked underground to a common mycelial network. [43] One plant may provide the photosynthate carbon for the establishment of the mycelial network that another plant of a different species can utilize for mineral ...
