- Abstract
Extracting RNA with high quality and integrity is crucial for molecular biology studies in eukaryotes. However, RNA isolation from cassava storage root raises a great concern because it contains large amounts of polysaccharides and polyphenol compounds. In the current study, four RNA extraction methods were evaluated for extracting RNA from cassava storage root. We found that the modified TM method (MTM) is timesaving and low-cost extraction method with high quality and quantities of RNA. The effectiveness of the improved method was assessed for qPCR analysis of four selected genes from total RNA of storage root. The improved protocol generated 4.18-5.94 µg RNA/g fresh weight. An A260/280 ratios of RNA samples are ranged from 2.14 to 2.17. The RIN values are ranged from 7.2 to 8.0. Importantly, isolated total RNA by MTM was successfully used for library construction and transcriptome sequencing. Therefore, we provide an efficient and low-cost method, MTM, for extracting high quality and quantities of RNA from cassava storage root.
