Physiological and metabolic responses to hypersalinity reveal interpopulation tolerance in the green macroalga Ulva compressa with different pollution histories

Environmental history affects the growth and photosynthesis of a green‐tide macroalgae Ulva prolifera

“…Both the exhibited compensatory growth against low or moderate level of herbivory (Cerda et al, 2009;Vergés et al, 2008). In addition, the historical backgrounds of exposition to stress mediated the physiological and metabolic responses of U. compressa to hypersalinity (Muñoz et al, 2020). Paige (2018) showed that the oxidative pentose phosphate pathway played an important role in influencing compensation.…”

“…The papers about the effects of one, two or multiple environmental factors on the growth, metabolism and reproduction in Ulva spp. have increased quickly (Cui et al, 2015; Xu et al, 2016; Gao et al, 2017; Gao et al, 2018; He et al, 2018; Tremblay‐Gratton et al, 2018; Wu et al, 2018; Jiang et al, 2020; Muñoz et al, 2020; Kang et al, 2021). These studies have observed different responses among species and/or growth stages to temperature and light, with higher growth for the young Ulva spp.…”

“…For these thalli collected from different sea area or in different seasons, they have different environmental history. In fact, the importance of previous stress encounters in promoting community tolerance has been reported (Baho et al, 2021;Fernández et al, 2021;Muñoz et al, 2020;Page et al, 2021). The responses of kelp Macrocystis pyrifera to ocean acidification and warming, as well as the physiological and metabolic responses of U. compressa to hypersalinity, were affected by the environmental history (Fernández et al, 2021;Muñoz et al, 2020).…”

The tolerance of coralline algae to additional acute thermal stress was reduced by elevated temperature history (Page et al, 2021).…”

Benzopyrene induces oxidative stress and increases expression and activities of antioxidant enzymes, and CYP450 and GST metabolizing enzymes in Ulva lactuca (Chlorophyta)

“…The complexity of carbon metabolism in U. lactuca has been described as a strategy to survive episodes of desiccation and resubmersion in the intertidal zones to obtain energy from different carbon sources (Gupta and Kushwaha 2017). In addition, U. lactuca is a cosmopolitan species that has been found in the intertidal zones of central Chile, that are polluted with crude oil such as Ventanas and Quintero-Puchuncaví (Muñoz et al 2020). Thus, U. lactuca constitute an interesting model to study the mechanisms involved in xenobiotic detoxification in marine algae.…”
