Characterization and identification of the key volatile and non-volatile substances of Vangueria madagascariensis J.F. Gmel fruits (Kirkir) and exploration of their binding interactions with olfactory and taste receptors using computational chemistry methodology. Food Chem 2024; 460:140631. [PMID: 39128364 DOI: 10.1016/j.foodchem.2024.140631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2024] [Revised: 07/19/2024] [Accepted: 07/23/2024] [Indexed: 08/13/2024]
Abstract
Profiling of metabolites that contribute to the taste and odor of fruit products is important to produce the desired products. In this study, volatile and non-volatile compounds were analyzed using SPME/GC-MS and UHPLC-Q-Exactive-orbitrap-MS/MS, respectively. A total of 59 volatiles (including alcohols, aldehydes, acids, terpenes, ketones, phenols, and hydrocarbons et al.) and 18 non-volatiles (including phenolic acids, flavones, flavonoids, glucosides, phenols, and quinic acid derivatives et al.) were detected in dried Kirkir fruits. The binding interactions between the key volatiles and the detected non-volatiles with taste and olfactory receptors were also evaluated. Based on the molecular docking, 11 volatile compounds may contribute to the overall odor, while 16 non-volatile compounds may contribute to the taste of the Kirkir fruits. In conclusion, in silico studies can serve as a powerful technique for understanding mechanisms of interaction and predicting the key phytochemicals that contribute to the odor and taste of fruits.

Feng L, Lin Y, Cai Y, Wei W, Yang J, Zhan R, Ma D. Terpenoid VOC profiles and functional characterization of terpene synthases in diploid and tetraploid cytotypes of Chrysanthemum indicum L. PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2023; 200:107766. [PMID: 37220674 DOI: 10.1016/j.plaphy.2023.107766] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Revised: 04/27/2023] [Accepted: 05/14/2023] [Indexed: 05/25/2023]
Abstract
Chrysanthemum indicum L. is a valuable medicinal plant with diploid and tetraploid forms that are widely distributed in central and southern China, and it contains abundant volatile organic compounds (VOCs). Despite the discovery of some terpene synthase (TPS) in C. indicum (i.e., CiTPS) in previous studies, many TPSs and their corresponding terpene biosynthesis pathways have yet to be discovered. In the present study, terpenoid VOCs in different tissues from two cytotypes of C. indicum were analyzed. We identified 52 types of terpenoid VOCs and systematically investigated the content and distribution of these compounds in various tissues. The two cytotypes of C. indicum exhibited different volatile terpenoid profiles. The content of monoterpenes and sesquiterpenes in the two cytotypes showed an opposite trend. In addition, four full-length candidate TPSs (named CiTPS5-8) were cloned from Ci-GD4x, and their homologous TPS genes were screened based on the genome data of Ci-HB2x. These eight TPSs displayed various tissue expression patterns and were discovered to produce 22 terpenoids, 5 of which are monoterpenes and 17 are sesquiterpenes. We further proposed corresponding terpene synthesis pathways, which can enable the establishment of an understanding of the volatile terpenoid profiles of C. indicum with different cytotypes. This knowledge may provide a further understanding of germplasm in C. indicum and may be useful for biotechnology applications of Chrysanthemum plants.

Callejas-Chavero A, Martínez-Hernández DG, Vargas-Mendoza CF, Flores-Martínez A. Herbivory in Myrtillocactus geometrizans (Cactaceae): Do Parasitoids Provide Indirect Defense or a Direct Advantage? PLANTS (BASEL, SWITZERLAND) 2022; 12:47. [PMID: 36616177 PMCID: PMC9824105 DOI: 10.3390/plants12010047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 11/27/2022] [Accepted: 12/12/2022] [Indexed: 06/17/2023]
Abstract
Plants respond to herbivory in diverse, complex ways, ranging from avoidance or tolerance to indirect defense mechanisms such as attracting natural enemies of herbivores, i.e., parasitoids or predators, to strengthen their defense. Defense provided by parasitoids to cultivated plants is well documented and is used in biological control programs. However, its effectiveness on wild plants under natural conditions has been little studied. Such is the case of the cactus Myrtilllocactus geometrizans (known in Mexico as garambullo), which is consumed by the soft-scale insect Toumeyella martinezae (herbivore) which, in turn, is host to the parasitoid wasp Mexidalgus toumeyellus, and mutualist with the ant Liometopum apiculatum, that tenders and protects it. This study explores the role of the parasitoid as an indirect defense, by examining its effect on both the herbivore and the plant, and how this interaction is affected by the presence of the mutualistic ant. We found that scales adversely affect the cactus' growth, flower, and fruit production, as well as its progeny's performance, as seedlings from scale-infested garambullo plants were shorter, and it also favors the presence of fungus (sooty mold). The parasitoid responded positively to herbivore abundance, but the presence of ants reduced the intensity of parasitism. Our results show that parasitoids can function as an indirect defense, but their effectiveness is reduced by the presence of the herbivore's mutualistic ant.
