Dataset Summary
| Title | Label-Free Proteomics Revealed Drought Stress Tolerance Mechanisms in the Sugar Beet Monosomic Addition Line M14 |
| Description | Sugar beet M14 line is a diploid cultivated sugar beet (Beta vulgaris L.) that carries a monosomic addition of chromosome 9 from the wild white-flowered beet (B. corolliflora Zoss.), developed through distant hybridization. It exhibits enhanced salt and drought tolerance compared to the diploid cultivated beets. In this study, the M14 line exhibited superior water retention capacity under dehydration conditions compared with five major diploid cultivated varieties grown in northern China. Through integrated analysis of phenotype, photosynthetic parameters, physiological and biochemical indicators, and the expression of key drought-responsive genes, 3 days and 5 days of 20% PEG-6000 treatment were identified as two critical time points for the drought stress response of the M14 line. Through label-free quantitative proteomics, 903 and 526 differentially expressed proteins (DEPs) were identified at 3 and 5 days, respectively. Protein-protein interaction (PPI) network analysis further revealed key protein interaction modules in the M14 line under drought stress. Furthermore, qRT-PCR analysis of 12 key DEP-encoding genes revealed that their transcript levels generally corresponded to the protein expression trends. This study helped to produce molecular network maps of drought tolerance in the beet M14 line, uncovering the mechanisms underlying its drought tolerance. |
