Root tissue transcriptome analysis of citrus Huanglongbing before and after FOS (Fosthiazate) + CAC(Cupric-Ammoniun complex) combination treatment

Goal: What is the difference in the transcriptome of the root tissue before and after Fosthiazate and Cupric-Ammoniun complex combination treatment?Relevance:Sample A: post-treatment root fiberSample B: pre-treatment root fiber no- RDRX (root tissue being decomposed and the remained xylem)Sample C: pre-treatment root fiber RDRX, because there are a large number of rotten roots, there is very little citrus tissue, so there is no way to use citrus database data for comparison.
