Title	Proteomic responses to varying temperatures in a calcareous green macroalga
Description	Genus Halimeda is a worldwide distributed reef-building organism facilitated by fast growth and a rapid turnover rate in tropical and sub-tropical oceans. It is an excellent candidate for calcareous algae research because its calcification occurs extracellular, which deposits aragonite in the semi-enclosed inter-utricle space. In this study, we sampled the thalli of Halimeda macroloba in Sanya Bay of the South China Sea. The mean winter and summer water temperatures in Sanya Bay were 25.05℃ and 28.72℃, respectively. Additionally, the mean surface and bottom layer water temperatures in summer were 29.61℃ and 27.23℃. In order to simulate the natural temperature range, a factorial experimental design with three treatments (25°C, 28°C, and 31°C) was set. The goal of this study was to decipher the underlying traits that may facilitate H. opuntia to maintain high productivity and active physiology under different temperatures. Here, we employed iTRAQ-based quantitative proteomics and untargeted metabolomics approaches to investigate the protein and metabolite profiles of H. macroloba.
