Resolvins (Rvs) fall into several sub-classes based on the straight chain PUFA from which they are formed and derive their unique structure. The resolvins Ds (RvDs) are metabolites of the 22-carbon PUFA, DHA (i.e. 4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoic acid); the resolvins Es (RvEs) are metabolites of the 20-carbon PUFA, EPA (i.e. 5Z,8Z,11Z,14Z,17Z-eicosapentaenoic acid); the resolvins D n-6DPA ...
The artificial solution described by Dennis Hoagland in 1933, [1] known as Hoagland solution (0), has been modified several times, mainly to add ferric chelates to keep iron effectively in solution, [6] and to optimize the composition and concentration of other trace elements, some of which are not generally credited with a function in plant nutrition.

Rose is one of the most popular natural flowers used in perfumery. A semi-solid residue of essential oils, waxes, resins and other oil-soluble plant chemicals remains. [2] The solvent used for extraction must be chosen carefully regarding its polarity and boiling point. If the boiling point is too high, compounds that are readily deactivated by ...
n-3 DPA is an n-3 fatty acid with the trivial name clupanodonic acid. It is an intermediate compound between eicosapentaenoic acid (EPA 5,8,11,14,17-20:5n-3 or timnodonic acid ) and docosahexaenoic acid (DHA 4,7,10,13,16,19-22:6n-3 or cervonic acid) in the metabolic pathway of DHA in eucaryotes.
Ion balance is a key factor in plant development to produce yield. Too high salt concentration in soil lowers the water potential in root tissue which becomes toxic; stunting growth and inhibiting flowering by dehydrating the plant. Stomatal closure is also a response to high salinity, leading to lowered sugar production and transpiration rates ...
Acid growth refers to the ability of plant cells and plant cell walls to elongate or expand quickly at low (acidic) pH. The cell wall needs to be modified in order to maintain the turgor pressure. This modification is controlled by plant hormones like auxin. Auxin also controls the expression of some cell wall genes. [1]
Human cells and mouse tissues metabolize n-3 docosapentaenoic acid (i.e., 7Z,10Z,13Z,16Z,19Z-docosapentaenoic acid, or clupanodonic acid) to a series of products that have been classified as specialized proresolvin mediators. Base on the analogy to docosahexaenoic acid metabolism to resolving D's, it is presumed that a 15-lipoxygenase, most ...
Ethephon is often used on wheat, coffee, tobacco, cotton, and rice in order to help the plant's fruit reach ripeness more quickly. Cotton is the most important single crop use for ethephon. It initiates fruiting over a period of several weeks, promotes early concentrated boll opening, and enhances defoliation to facilitate and improve the ...
