“…domestica L. are particularly diverse in terms of size, color, and flavor. Histochemical analyses of the fruit development can be helpful for understanding the regulation of synthesis and accumulation of metabolites affecting color and flavor during development of plant organs. − The morphological and anatomical development of drupes of Prunus species have been characterized by histological studies, but most of them did not address the localization of secondary metabolites. , However, when specific staining and techniques are applied, different metabolites, such as pectin, lipids, lignin, proteins, phenolic compounds, tannins, starch grains, essential oils, rubber, and terpenoids, can be detected. ,− The observation of handmade fresh sections of plant tissue in a light microscope enables rapid monitoring of plant organs under altered growth conditions, for example, for the localization of flavonols and flavan-3-ols in Tsuga sp. and Taxus sp.…”

As a result of the high variability of fruit properties in the European plum Prunus domestica, a histochemical analysis of fruits at different stages of development was performed to understand the ripening process in cv. 'Colora' (yellow− red skinned) and cv. 'Topfive' (purple skinned). Histological analysis showed that carotenoids in the fruit had two different origins. In the fruit flesh, they derived from chloroplasts that turned into chromoplasts, whereas carotenoids in the fruit skin derived probably from proplastids. Flavan-3-ols and proanthocyanidins showed differential localization during ripening. They were visible in the vacuole in different fruit tissues or organized in tannosomes in the fruit flesh. Tanninoplasts were observed only in hypodermal cells of 'Colora'. Toward maturity, anthocyanins were detected in the epidermis and later in the hypodermis of both cultivars. The study forms a basis for the analysis of the biosynthesis of secondary metabolites in European plums and their biological effects.

Hesperozygis ringens é uma espécie nativa e endêmica do Rio Grande do Sul pertencente à Lamiaceae. Essa planta arbustiva está distribuída em cinco municípios gaúchos e encontrada em regiões restritas próximo a locais arenosos e pedregosos. O forte odor característico da espécie é proporcionado pelo óleo essencial, mais especificamente a pulegona como o principal constituinte. Este trabalho propôs, por meio de uma revisão, apresentar o potencial de H. ringens em diversas linhas de ação das propriedades dos óleos essenciais, assim como a sua composição química. Estudos realizados mostraram a ação antiparasitária e alelopática em algumas espécies de pragas, parasitas e plantas daninhas, o que a favorece como alternativa na produção de antiparasitários e herbicidas naturais. Outras propriedades se destacam na atividade anestésica e bactericida para o controle de microrganismos parasitas de peixes, aspectos de grande interesse na piscicultura. Mais recentemente, foi detectada a presença do ácido rosmarínico, responsável pelas propriedades medicinais. Com todos os estudos que estão sendo desenvolvidos, H. ringens torna-se uma espécie promissora, porém atualmente essa espécie se encontra ameaçada de extinção. Como forma de propagação, a estaquia pode ser uma alternativa de reprodução.
