This document provides a comprehensive overview of the Rhizome Project meeting held on May 4, 2011, at the Institute of Biological Chemistry, Washington State University. Led by Min-Jeong Kim, the meeting discussed methodologies for gene analysis using mRNA, microarray, and RNA sequencing (RNA-seq). Key topics included total RNA purification with Qiagen kits, cDNA library preparation, sequencing data analysis, and transcriptome analysis of rhizome parts. The collaboration with NCGR for sequencing and the integration of multiplexed RNA-seq methodologies were also highlighted.
