“…Such behavior can be explained by changes in secondary metabolism, which favors the biosynthesis of volatile compounds due to the induction of specific enzymes (Venditti et al, 2015). Although essential oil biosynthesis is determined by genetics, the content and proportion of chemical constituents of essential oils are intensely affected by geographical origin (Santos, Pinto, Santos, Cruz, & Arrigoni-Blank, 2016).…”

Varronia curassavica (Jacq.) is a shrub and perennial plant native to Brazil that has therapeutic, anti-inflammatory and cicatrizing properties. The objective of this work was to study the chemical diversity of the native populations of this species maintained in the in vivo germplasm bank from Montes Claros, Minas Gerais, Brazil. The essential oils of 10 accessions analyzed in triplicate were obtained by hydrodistillation. Fifty-five compounds were detected, 46 of which were identified by GC-MS analysis. Essential oil yield ranged from 0.1 (VC-9) to 1.22% (VC-3) among the studied accessions. Three groups were formed by cluster analysis. Group A presented lower relative abundance of the compounds α-humulene (1.4%) and β-caryophyllene (8.5%). Conversely, in Group B, the most abundant compound was α-humulene (31.6%). Group C, with the greatest number of accessions, presented values of up to 6.1 and 41.2% for α-humulene and β-caryophyllene, respectively. Only two accessions (VC-1 and VC-5) presented α-humulene content lower than that recommended for phytotherapeutic production. These results, along with consolidating breeding programs, contribute to the conservation of the species.

“…The study on the chemical diversity of essential oils is a strategy to characterize aromatic plants phenotypically. However, geo-climatic factors affect the chemical constitution of the essential oil, which hinders the study on how much of this variation is related to genetics Santos et al, 2016).…”

ABSTRACT. Eplingiella fruticosa (Salzm. ex Benth.) Harley & J.F.B. Pastore, ex Hyptis fruticosa Salzm. ex Benth. is an aromatic and medicinal plant of the family Lamiaceae, found mainly in regions with intense anthropic activity. Information on the genetic diversity of this species is scarce. However, it can be assessed using molecular markers that identify the level of diversity among phenotypically identical individuals. The present study aimed to characterize the genetic diversity of a native population of E. fruticosa from the State of Sergipe using ISSR molecular markers. Samples of 100 plants were collected in 11 municipalities of the State of Sergipe and analyzed using eight ISSR primers, resulting in 72 informative bands. The cluster analysis obtained using the neighbor joining method resulted in three groups: Group I consisted of 50 plants, mainly from the municipalities of Areia Branca, Estância, Japaratuba, Moita Bonita, Pirambu, and Salgado; Group II was .250), and the greatest distance occurred between plants EPF50 and EPF96 (0.9778). The Shannon index had a mean value of 0.42, and diversity was considered moderate. Heterozygosity had a mean value of 0.267 and was considered low. Polymorphic information content (0.253) was considered moderately informative. Genetic diversity of E. fruticosa plants was intermediate, and the results of the present study can assist in the conservation and use of the genetic resources of this species.

“…In addition, the stomatal mechanism inefficiency may lead to tissue dehydration and plant death during the acclimatization stage (Palma et al 2011). Hyperhydric tissues may show higher hydrogen peroxide concentrations; the higher ROS production results from the low oxygen availability to the cells (Sen and Alikamanoglu 2013;Dewir et al 2015). The higher APX activity in the current study has followed the high SOD activity, since the SOD acted in the O 2 Ádismutation and formed the H 2 O 2 substrate for the APX.…”

“…Species belonging to family Verbenaceae, especially those recorded in genus Lippia L., show remarkable antibacterial activity due to their chemical constitution, which mostly presents phenolic constituents (Cruz et al 2014;dos Santos et al 2016). Lippia grata Schauer, which is synonym of species: L. gracilis Schauer, L. dumetorum Herzog, L. laxibracteata Herzog and Lippia hickenii Tronc (O'Leary et al 2012), is endemic to the Brazilian Northeastern semiarid region (Gomes et al 2011).…”

Controlling hyperhydricity in micropropagated plants of Lippia grata Schauer (Verbenaceae), a native species of a dry seasonal tropical forest with pharmacological potential

The present study is to assess the morphophysiological development in vitro of Lippia grata Schauer, an endemic ''Caatinga'' species that shows pharmacological properties. Young cuttings containing nodal segments were divided into three explant types, namely E1 (apical bud), E2 (nodal segment below the apical bud) and E3 (nodal segment below E2); the explants were inoculated in MS medium supplemented with antioxidant compound (polyvinylpyrrolidone) or adsorbing agent (activated charcoal). The survival index, the occurrence of oxidation, contamination and the number of leaves and sprouts were assessed. The explants were cultivated in MS medium supplemented with polyethylene glycol 6000 (0, 0.5 and 1 g L-1) and closed with aluminum foil (total sealing) or with aluminum foil containing one hole (partial sealing), in the multiplication stage, due to hyperhydricity in vitro. Histological and biometric analyses were performed at the 45th cultivation day, as well as the analyses of antioxidative enzyme, and hydrogen peroxide and malondialdehyde levels. Normal leaves have presented greater organization and cellular development than hyperhydric leaves. The use of antioxidants was not efficient to control the oxidation of inoculated apical buds (E1), only. The lowest hyperhydricity rates in the multiplication stage were found in the partial sealing treatments; however, the total sealing of tubes, in combination with the PEG addition, has led to increased lipid peroxidation. In view of the results, it is concluded that the explant types, as well as the suitability of a functional gas exchange system in vitro, have favored the growth and development of cells and tissues, thus attenuating the hyperhydricity symptoms. In addition, this study demonstrates the suitability of the culture system through the facilitation of gas exchange allows the use of the protocol for in vitro propagation without compromising the leaf morphoanatomy.
