The Reactions of Photosynthetic Capacity and Plant Metabolites of Sedum hybridum L. in Response to Mild and Moderate Abiotic Stresses

Abstract

In this article, for the first time, an experimental study of the effect of mild and moderate osmotic stress, NaCl content and the effect of low positive temperature on photosynthetic activity and composition of metabolites of immature plants Sedum hybridum L. is reported. In this representative of the genus Sedum adapted to arid conditions and having the properties of a succulent, a change in photosynthetic activity and an increase in the level of protective metabolites in the shoots were revealed when exposed to mild and moderate stress factors. The results of this study can be used in work on the adaptation of succulent plants to arid conditions, environmental monitoring and work on the directed induction of valuable secondary metabolites in succulents to obtain new herbal medicines.

Anatomical and Metabolome Features of Haloxylon aphyllum and Haloxylon persicum Elucidate the Resilience against Gall-Forming Insects

“…Due to their labile hydroxyl group, tocopherols can readily react with hydrocarbon peroxide radicals [83]. Their concentrations are known to increase under moderate stress, a situation where plant damage does not result in fatality [84]. In the current study, tocopherol levels decreased in damaged H. aphyllum, while H. persicum showed an increase in tocopherol concentration under similar conditions.…”

Sedeveria pink ruby Extract-Mediated Synthesis of Gold and Silver Nanoparticles and Their Bioactivity against Livestock Pathogens and in Different Cell Lines

“…Sedum group succulent plants contain certain major metabolite groups, such as flavonoids, tannins, terpenoids, carbohydrates, and amino acids. In addition, SP extract has been used as an antiseptic, antibacterial, and diuretic in traditional medicine, indicating the functions of this plant in folk medicine [ 46 ].…”

Accumulation of Secondary Metabolites of Rhodiola semenovii Boriss. In Situ in the Dynamics of Growth and Development

“…We assume that the level of stress tolerance of a R. semenovii flower can primarily determine the presence of terpenoids (1.4%), lactones (9.7%), phenols (1.8%), and alcane such as heneicosane (21.3%) detected by this experiment, which, according to the literature, quantitatively depends on the type of habitat [ 61 ]. Furthermore, signaling molecules formed from the group of polyunsaturated fatty acids are involved in the formation of body responses to various environmental signals [ 4 , 62 ].…”
