| Summary: | High RNA quality, integrity and reproducibility are essential for functional genomics study involving library preparation and
sequencing using next generation sequencing (NGS) technologies. The medicinal herbaceous plant, Impatiens balsamina,
possess a rich source of diverse bioactive compounds including polysaccharides and phenolic compounds, hindering the
extraction of high quality total RNAs. Four existing RNA extraction protocols were performed using fresh leaf material of I.
balsamina, namely the CTAB method, the TRI reagent® method, modified TRI reagent® method and a commercial kit but
the results were unsatisfactory. This led to the development of a modified CTAB protocol by combining CTAB/
polyvinylpyrrolidone (PVP) extraction with using commercial spin column purification for successful isolation of high quality
total RNA from the leaf material of I. balsamina, that is suitable for NGS applications (RIN values > 7). This new method
also successfully extracted total RNA from flower buds and capsules of I. balsamina. |
