PRJNA280380: Host transcriptional reprogramming across diverse strains of the rice bacterial leaf streak pathogen Xanthomonas oryzae pv.oryzicola

Summary: We performed RNA-Seq of leaves of Oryza sativa L. ssp. japonica cv. Nipponbare 48 hours after inoculation with 10 geographically diverse strains of Xanthomonas oryzae pv. oryzicola, the causal agent of bacterial leaf streak. Results provide insight into the molecular basis of bacterial leaf streak, particularly the role of transcription activator-like effectors in the disease.

Overall Design: Examination of mRNA levels in Oryza sativa L. ssp. japonica cv. Nipponbare leaves at 48 hours after inoculation with 10 strains of Xanthomonas oryzae pv.oryzicola with three biological replicates for each compared to three replicates of mock inoculated O sativa as the control

Protocol
Growth Protocol: Oryza sativa L. ssp. japonica cv. Nipponbare plants to be inoculated were grown in LC-1 soil mixture (Sungro, Bellevue, WA) in PGC15 growth chambers (Percival Scientific, Perry, IA) in trays approximately 60 cm below a combination of fluorescent and incandescent bulbs providing approximately 1,000 μmoles/m2/s measured at 15 cm, under a cycle of 12 h of light at 28 °C and 12 h of dark at 25 °C.
Treatment Protocol: Plants were inoculated at two weeks with bacterial suspensions in 10 mM MgCl2 at approximately OD600=0.4 or with a mock inoculum of 10 mM MgCl2, by infiltration using a needleless syringe. For each inoculum, the second and third leaves of each of four plants were infiltrated at 20 contiguous spots per leaf. From each of the eight leaves inoculated with mock inoculum or a single strain, a 12 cm length of the inoculated portion was collected after 48 hours and the tissue from all eight leaves pooled together for RNA isolation.
Extract Protocol: RNA was extracted using a modified hot Trizol protocol (Huang et al., 2005) followed by treatment with RNase-free DNase I (Life Technologies, Carlsbad, CA), then purified using the RNeasy MinElute Cleanup kit (Qiagen, Valencia, CA).
Library Construction Protocol: These libraries were prepped with the Illumina TruSeq RNA Sample Prep v2 kit.

TAL effectors and activation of predicted host targets distinguish Asian from African strains of the rice pathogen Xanthomonas oryzae pv. oryzicola while strict conservation suggests universal importance of five TAL effectors.
