    Protein and metabolite acclimations to temperature variability in a calcareous green macroalga Halimeda macroloba by Hao Zhang, Yuyu Wang, Lingshuai Zhang, Zhiqin Wang, Zejun Zhu, Lijuan Long, Lijuan Long

    Published 2025-02-01
    “…At the supra-optimal temperature of 31°C, despite reduced photosynthetic performance, the alga maintained high metabolic activity to facilitate growth and calcification by increasing the abundance of proteins involved in light-harvesting, photosystems, and carbon fixation, while redistributing substantial carbon into sugars and fatty acids. Enhanced nitrogen reserves, shown by increased levels of nitrogen uptake and assimilation proteins and amino acids such as pyroglutamic and N-Methyl-D-aspartic acids, likely contributed to its high-temperature tolerance. …”
