A plant cuticle is a protecting film covering the outermost skin layer of leaves, young shoots and other aerial plant organs (aerial here meaning all plant parts not embedded in soil or other substrate) that have no periderm. The film consists of lipid and hydrocarbon polymers infused with wax, and is synthesized exclusively by the epidermal cells.
Cutin is one of two waxy polymers that are the main components of the plant cuticle, which covers all aerial surfaces of plants, the other being cutan. It is an insoluble substance with waterproof quality. Cutin also harbors cuticular waxes, which assist in cuticle structure. [1]
There is no one universal method to cuticle analysis. Rather, it is the shared principle on which the applications are based which underpins the methodology—namely, that a well-preserved plant cuticle can, through the use of microscopy, yield information regarding the nature of the plant from which it originated, including its species and the environmental stresses acting upon it.
Elsholtzia ciliata, commonly known as Vietnamese balm, comb mint, xiang ru (香薷) or kinh giới in Vietnamese, is a flowering plant in the family Lamiaceae native to Asia. In the US, it is commonly known as Crested Late Summer Mint. [1] In US Vietnamese grocery stores, it is called Kinh Gioi, Vietnamese Lemon Balm, or Vietnamese Lemon Mint. [2]
Epicuticular wax is a waxy coating which covers the outer surface of the plant cuticle in land plants. It may form a whitish film or bloom on leaves, fruits and other plant organs. Chemically, it consists of hydrophobic organic compounds, mainly straight-chain aliphatic hydrocarbons with or without a variety of substituted functional groups ...
The hardening of the cuticle is due to the presence of a polyphenol oxidase. [38] In crustaceans, there is a second oxidase activity leading to cuticle pigmentation . [ 39 ] There is apparently no polyphenol tanning occurring in arachnids cuticle.
Cytisus scoparius (syn. Sarothamnus scoparius), the common broom or Scotch broom, is a deciduous leguminous shrub native to western and central Europe. [2] In Great Britain and Ireland, the standard name is broom; [3] [4] [5] this name is also used for other members of the Genisteae tribe, such as French broom or Spanish broom; and the term common broom is sometimes used for clarification.
All plant organs arise ultimately from cell divisions in the apical meristems, followed by cell expansion and differentiation. Primary growth gives rise to the apical part of many plants. The growth of nitrogen-fixing root nodules on legume plants such as soybean and pea is either determinate or indeterminate. Thus, soybean (or bean and Lotus ...
