Abstract
Background: There is a growing interest in transcriptomics studies parallel to the advancement of transcriptome databases and bioinformatics, which provided the opportunity to study responses to growths, stimuli and stresses. There is an increase in demand for excellent RNA extraction techniques. General RNA extraction protocols can be used in RNA extraction, but the quality and quantity vary in diferent types of tissues from diferent organisms. Hence, a specifc RNA extraction method for each organism’s tissue type is required to obtain the desired RNA quality and quantity. Results: The improved CTAB RNA extraction method is superior to the PCI method and MRIP method for thick waxy leaves that were applied for mature sago palm (Metroxylon sagu Rottb.) leaf tissue and produce total RNA extract with good purity (OD 260/280≥1.8, OD 260/230≥2.0) and integrity (RIN~7). RNA sequencing was conducted with the extracted samples and showed good assembly results (Q20≥97, Q30≥91%, assembly mean length≥700 bp). Conclusion: The improved CTAB RNA extraction method enables rapid, cost-efective, and relatively simple RNA extraction from waxy, fbrous and high-in-polyphenol sago palm (M. sagu Rottb.) leaf tissue with next-generation RNA sequencing recommended quality.
