cutin and
suberin), which make cell walls water- and air-tight, and afford protection against microbial attacks (Boom et al.
Homologs in other plants of most of these genes have been associated with the process of pollen wall development, such as
suberin biosynthesis [43, 44], cutin biosynthesis [45-47], pollen sporopollenin biosynthesis [48], and pollen exine formation [49-51].

suberin production in potato tuber (Solanum tuberosum)," Journal of Agricultural and Food Chemistry, vol.
It is probably because of
suberin in cork and impurities (Zhao 2012).
Tests using lugol were carried out on leaves and roots for the detection of starch (Johansen, 1940), phloroglucinol for the detection of lignin and
suberin (Jensen, 1962) and toluidine blue for mucilage (O'Brien et al., 1965).
These substances are divided into classes: glycosylated phenylpropanoids, flavonoids, isoflavonoids, stilbenoids, coumarins, curcuminoids, as well as phenolic polymers such as tannins, proanthocyanidins,
suberin, lignins, and lignans.
S-metolachlor acts by interfering with the activity of acyl-CoA elongases, which are enzymes that catalyze the synthesis of very long chain lipids, precursors of wax,
suberin and cutin (Vidal et al., 2014).
Pollen is surrounded by a complex protective outer membrane called exine, that is characterized for being resistant and firm, and composed of Sporopollenin, which are biopolymers as cutin (composed of fatty acids to protect the cell surface),
suberin (polymer of long-chain fatty acids) and lignins (phenolic compounds) (Zuluaga et al., 2014).
Aside from promoting a healthy lifestyle, the answer is Cork.The substance is beneficial when used in the footbed of the sandals as well as in the formulation of the body products, because cork contains
suberin, which has a proven lifting effect.
Four layers of parenchyma cells are usually present in the cortex (Figure 2A), but lacking the exodermis with
suberin; the endodermis is present (Figure 2A), but without evident Casparian strips.
