Therefore, electrophoresis of positively charged particles or molecules is sometimes called cataphoresis, while electrophoresis of negatively charged particles or molecules (anions) is sometimes called anaphoresis.
Ectomycorrhizal symbiosis, showing root tips with fungal mycelium from the genus Amanita. An ectomycorrhiza (from Greek ἐκτός ektos, "outside", μύκης mykes, "fungus", and ῥίζα rhiza, "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species.
Capsidiol is a phytoalexin produced by certain plants in response to pathogenic attack.. Phytoalexins are antimicrobial substances, some of which are antioxidative as well. They are defined not by their having any particular chemical structure or character, but by the fact that they are defensively synthesized de novo by plants that produce the compounds rapidly at sites of pathogen infection.
SlideBoom turns slide presentations into Adobe Flash so they can be viewed without slide presentation software. [11] [12] SlideOnline allows the user to upload PowerPoint presentations and share them as a web page in any device or to embed them in WordPress as part of the posts comments. [13] Another way of sharing slides is by turning them ...
Many invasive plant species interfere with native plants through allelopathy. [ 20 ] [ 21 ] A famous case of purported allelopathy is in desert shrubs . One of the most widely known early examples was Salvia leucophylla , because it was on the cover of the journal Science in 1964. [ 22 ]
The word derives from Ancient Greek ἅλας (halas) 'salt' and φυτόν (phyton) 'plant'. Halophytes have different anatomy, physiology and biochemistry than glycophytes. [1] An example of a halophyte is the salt marsh grass Spartina alterniflora (smooth cordgrass). Relatively few plant species are halophytes—perhaps only 2% of all plant ...
Phyllody of the bracts is common among plants which bear catkin (amentaceous) inflorescences. They are very common among members of the genus Plantago, for example, as well as the common hop (Humulus lupulus). Involucral bracts of the flowers of members of the family Asteraceae like dahlias and dandelions, may also be affected. [5]
Since the cryptochromes were discovered in plants, several labs have identified homologous genes and photoreceptors in a number of other organisms, including humans, mice and flies. [10] There are blue light photoreceptors that are not a part of photomorphogenesis. For example, phototropin is the blue light photoreceptor that controls phototropism.
