Transcriptome and Proteome Analysis Identifies Salt Stress Response Genes in Bottle Gourd Rootstock-Grafted Watermelon Seedlings

Soil salinization poses a huge challenge to the development of agriculture and seriously decreases crop yield quality. In recent years, grafting has become one key agronomic techniques used enhance plant abiotic stress tolerance. this study, we found that watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] grafted onto bottle gourd (Lagenaria siceraria Standl.) significantly enhanced salt Transcriptome analysis revealed total 8462 differentially expressed genes (DEGs) were identified, number up- down-regulated 3207 5255, respectively. The DEGs in rootstock-grafted plants mainly involved carbon metabolism, photosynthesis, hormone signal transduction. Furthermore, proteome identified 28 differently proteins (DEPs) under stress. These DEPs closely associated with amino acid protein synthesis, mitochondrial metabolism defense. Combined transcriptome analyses showed stress-responded seedlings transduction, synthesis pathways.
