Project description:Affymetrix soybean genome arrays were used to identify genes differentially expressed in the immune resistance response at 6, 12, 24, and 48 hours after inoculation with Phakopsora pachyrhizi isolates TW72-1 or HW94-1; soybean + HW94-1 = resistant; soybean + TW72-1 = susceptible Experiment Overall Design: For each of 4 time points (6, 12, 24 and 48 hours post inoculation) a soybean PI200492 plant was inoculated with 2 treatments: HW94-1, or TW72-1. A mock inoculation was performed and sampled at time 0. There were three biological replicates of the entire experiment, for a total of 27 samples. During data analysis two samples failed the quality control metrics and were removed from the analysis, leaving 25 samples in the final data set.
Project description:We explored the use of Phi in controlling the fungal pathogens Puccinia emaculata and Phakopsora pachyrhizi, the causal agents of switchgrass rust and Asian soybean rust, respectively. RNA sequencing of both the pathogens with and without treatment with Phi was conducted. Differentially expressed genes were identified in both pathogens and comparison of differentially expressed genes was made to identify commonly regulated genes by Phi. Total RNA from Phi‐treated Pe and Pp was isolated using an RNeasy plant mini kit (Qiagen). Two biological replicates were used for each treatment (12 samples). Illumina TruSeq sequencing‐by‐synthesis chemistry was used on a HiSeq 2000 platform (Illumina, https://www.illumina.com/) to generate paired‐end reads (2 × 100 bp).
