Bayogenin 3-O-Cellobioside is a novel anti-blast metabolite produced in rice in response to Pyricularia oryzae infection
Susceptible (CO39 and NPB) and resistant (Pi_gm) rice cultivars were spray inoculated with P. oryzae spore and incubated for 12-hours. Total RNA was extracted from the inoculated rice seedlings (T_Co39, T_NPB, and T_gm) along with their non-inoculated control group C_Co39, C_NPB, and C_gm. The extraction of total RNA from inoculated and non-inoculated control samples was carried-out with RNAprep pure Plant Kit (Tiangen, Beijing) by following processes recommended by the manufacturer. To observe the level of RNA degradation and contamination, the extracted RNA was run on 1% agarose gels. RNA integrity was assessed using the RNA Nano 6000 Assay Kit of the Bioanalyzer 2100 system (Agilent Technologies, CA, USA). RNA concentration was measured with RNA Assay Kit in Qubit 2.0 Fluorometer (Life Technologies, CA, USA). The cDNA library was sequenced on the Illumina sequencing platform (Illumina HiSeq™ 2000) with 150 bp pair-end reads length and 300 bp insert size by Gene Denovo Co. (Guangzhou, China). Novogene in-house Perl script was used to select clean reads by removing adaptor sequences, low quality sequences (reads with more than 50% of bases quality lower than 20) and reads with more than 5% N bases. Overall design: mRNA profile of susceptible and resistant rice seedlings inoculated with P. oryzae for 12-hours and non-inoculated control groups were generated through deep sequencing, data was obtained from one biological experiment with three technical replicates using Illumina HiSeq™ 2000.
