| Title |
Analysis of Transcriptomics and Rhizosphere Fungal Diversity in Different Tissues of Blueberry under Cadmium Stress |
| Organism |
Vaccinium ashei |
| Experiment type |
Expression profiling by high throughput sequencing
|
| Summary |
In this study, blueberry transcriptomics and rhizosphere fungal diversity were analyzed by simulated potting method to treat blueberries with Cd stress, and the content of Fe, Mn, Cu, Zn and Cd in each tissue, soil and DGT of blueberries were determined. , Combined with transcriptomics for correlation analysis. A total of 84374 annotated genes were obtained in blueberry roots, stems, leaves and fruits, of which 3370 DEGs were found, and DEGs in the stem accounted for the highest proportion, totaling 2521. The annotation results show that these DEGs are mainly concentrated in a series of metabolic pathways related to signal transduction, defense and pathogenic response. Blueberries transfer excess Cd from the root to the stem for storage. The stem contains the highest Cd content, which is consistent with the transcriptomics analysis results, while the fruit contains the lowest Cd content. Correlation analysis between heavy metal content and transcriptomics results in each tissue was carried out, and a series of genes related to Cd regulation were screened. The blueberry root system relies on mycorrhiza to absorb nutrients in the soil. The intervention of Cd has severely affected the microflora structure of the blueberry rhizosphere soil. Coniochaetaceae, which is extremely tolerant, has gradually become the dominant population.

| Overall design |
Apply CdSO4 in the form of an aqueous solution to control the Cd2+ concentration in the soil to 400.00mg/kg (calculated by the weight of pure metal). The control group is a potted plant (CK) without CdSO4, and the treatment is repeated three times for each group，Collect blueberry roots, branch, leaves and fruits for transcriptome sequencing
