摘要：An increasing number of moso bamboo habitats are suffering severe drought events. The improvement in our understanding of the mechanisms of drought-resistance in moso bamboo benefits their genetic improvement and maintenance of forest sustainability. Here, we investigated the metabolic changes across the annual growth cycle of moso bamboo in the field under drought stress using liquid chromatography coupled to mass spectrometry (LC-MS) based on untargeted metabolomic profiling. Our results showed that the metabolic profiles induced by drought stress were relatively consistent among the three growth stages. Specifically, most responsive metabolites exhibited enhanced accumulation under drought stress, including anthocyanins, glycosides, organic acids, amino acids, and sugars and sugar alcohols. The potential metabolism pathways involved in the response to drought stress were mainly included into amino acid metabolism and sugar metabolism pathways. Five common responsive metabolic pathways were found among three growth stages, including linoleic acid metabolism, ubiquinone and other terpenoid-quinone biosynthesis, tyrosine metabolism, starch and sucrose metabolism and isoquinoline alkaloid biosynthesis. Overall, our findings provide new insights into the responsive mechanisms of the moso bamboo under drought stress in terms of metabolic profiles. (C) 2020 Elsevier B.V. All rights reserved.
