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 ...
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 ...
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.
Rose Brystowski, 68, had a choice to make. Others might have found it difficult. She found it easy. Brystowski, of Oak Park, Michigan, wasn't about to let her genetics forfeit her future. Doctors ...

Low-phosphorus concentrations in the soil increase hyphal growth and branching as well as induce plant exudation of compounds that control hyphal branching intensity. [22] [24] The branching of AM fungal hyphae grown in phosphorus media of 1 mM is significantly reduced, but the length of the germ tube and total hyphal growth were not affected.
