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

Abstract

spp. has found itself at the centre of controversy. On the one hand, Ulva possesses high nutrient value, is rich in omega-3 (n3) fatty acids (McCauley et al., 2016), rare cell-wall polysaccharide and can be used as a natural source of dietary fibre (Bolton et al., 2016), animal feeds (Mata et al., 2016) and bioindicator of trace element contamination (Bonanno et al., 2020), as well as used for wastewater treatment (Henriques et al., 2019). On the contrary, Ulva spp. are the dominant species in green macroalgal blooms (Liu et al., 2013). The papers about the effects of one, two or multiple environmental factors on the growth, metabolism and reproduction in Ulva spp. have

Review of Allelopathy in Green Tides: The Case of Ulva prolifera in the South Yellow Sea

“…Phenols are intermediate products of the ascorbate-glutathione (ASA-GSH) cycle, which is how U. prolifera activates its antioxidant system to cope with stress, under low-dose and short-term radiation exposure [ 48 , 78 ]. Meantime, U. prolifera ’s antioxidant system also helps to control photorespiration metabolism and keeps photosynthesis efficient, which allows it to survive and proliferate in unfavorable environments [ 79 ]. Part of the reason for the quick adaption and renewal of U. prolifera is its genes, which are essential for the manufacture of phenolic chemicals that allow the green macroalgae to spread quickly in their native habitat [ 80 ].…”
