Project description:In the family Fagaceae, fertilization is delayed by several weeks to more than one year after pollination, leading to one- or two-year fruiting species depending on whether fruiting occurs in the same or the next year of flowering. Although delayed fertilization was recorded over a century ago, underlying mechanisms remain to be explored. To uncover the key genes associated with delayed fertilization, we obtain and analyze the comparative molecular phenology data over two years in one-year (Quercus glauca) and two-year fruiting species (Lithocarpus edulis).
Project description:<p>This study presents an untargeted LC-MS-based metabolomics dataset generated from leaves of Quercus glauca subjected to drought stress and exogenous brassinosteroid treatment. Leaf samples were collected at multiple time points under control, drought, and drought plus brassinosteroid conditions to capture dynamic metabolic responses. Metabolites were extracted and analyzed using reverse-phase UPLC coupled with high-resolution mass spectrometry in both positive and negative ion modes. This dataset provides a comprehensive resource for investigating metabolic reprogramming associated with drought stress and brassinosteroid-mediated stress mitigation in woody plant species.</p>
