Biotic and abiotic stress-induced phenylpropanoids in leaves of the mango (Mangifera indica L., Anacardiaceae)

Abstract

A composição química de plantas é afetada por estresses abióticos e bióticos. No caso da Mangifera indica foi observado que as suas folhas respondem claramente a ataque do gafanhoto Tropidacris collaris e por dano causado mecanicamente, biossintetizando diversos compostos voláteis associados aos estresses, principalmente fenilpropanóides como miristicina, dilapiol, eugenol e acetato de eugenol. A identificação desses fenilpropanóides em folhas de mangueira como resposta aos estresses abióticos e bióticos é crucial à pesquisa de novos pesticidas naturais, considerando que fenilpropanóides possuem diversas atividades biológicas, principalmente inseticidas.It is now widely recognized that plant's chemical composition is affected by both abiotic and biotic stress. This is the case of Mangifera indica leaves which respond very clearly to the damages caused by the grasshopper Tropidacris collaris and to mechanical damage by biosynthesizing several stress-related volatile compounds, mainly phenylpropanoids such as myristicin, dillapiole, eugenol and eugenol acetate. The identification of these phenylpropanoids in mango leaves in response to abiotic and biotic stress factors is a key step in the search for new natural pesticides, since phenylpropanoids have various biological activities, mainly insecticidal.

Fruit aromas in mature fleshy fruits as signals of readiness for predation and seed dispersal

“…; A. Rodríguez et al ., unpublished). For example, mono‐ and sesquiterpenes are major compounds of mango leaves and fruits, although specific VOCs can be ascribed to each tissue, such as esters that are not detected in leaves (Lalel et al ., ; Silva et al ., ). Similarly, important scent VOCs in ripe peach (linalool and C10 lactones) are absent from leaves (Horvat & Chapman, ).…”

Growth and Molecular Expression of Okra Seeds Interacted with Fourteen Mango Cultivars in Mixed Cropping System

“…The reduction in both radicle length and hypocotyl length may be due to phytotoxic activity of phytochemicals present in aqueous extracts of M. indica leaves like mangiferin, saponin, steroids, tannin, flavonoid, reducing sugars and cardiac glycosides (Jutiviboonsuk & Sardsaengjun, 2010;Bhuvaneswari, 2013). It also contains phenolics like polyphenols, ferulic, cumaric acid, benzoic, vanelic, chlorogenic, caffeic, gallic, hydroxybenzoic, phenylpropanoids, mangiferin, mangin and cinnamon, These phenolic compounds have interfered with the phosphorylation pathway or inhibiting the activation of Mg 2+ and ATPase activity or might be due to decreased synthesis of total carbohydrates, proteins and nucleic acids (DNA and RNA) or interference in cell division, mineral uptake and biosynthetic processes (El-Rokiek et al, 2010;Silva et al, 2012;El-Darier et al, 2015).…”

CitAP2.10activation of the terpene synthaseCsTPS1is associated with the synthesis of (+)-valencene in ‘Newhall’ orange

“…Most fruit, such as mango ( Singh and Saini, 2014 ), strawberry ( Van de Poel et al , 2014 ), pear ( Moya-Leon et al , 2006 ), melon ( Gonda et al , 2013 ), and citrus ( Shi et al , 2007 ) produce large amounts of volatiles. Fruits are particularly useful for aroma research, as specific compounds are unique to the fruit and are not found in other plant tissues, e.g., esters can be detected in mango fruit but are absent from leaves ( da Silva et al , 2012 ; Lalel et al , 2003 ), and linalool and C10 lactones appear in ripe peach but are absent from leaves ( Horvat and Chapman, 1990 ). Citrus fruit are also excellent materials for terpenoid research.…”
