RNA extracted from different cinnamon tissue types. Representative RNA gel images of Cinnamon from different maturity stages (Bark and leaf): a obtained by traditional CTAB method with partially degraded RNA; b without PVP in CTAB buffer; c and different tissue types after pH optimization of CTAB buffer; d after DNase treatment: e Representative bioanalyzer electropherograms of (01) Immature bark (02) Mature leaf. RNA Gels were resolved on 1.2% Agarose gel. ^†IMB immature bark, INB intermediate bark, MB mature bark, IL immature leaf, ML mature leaf, RT root, FL flower, ST inner stem. ^‡Electropherograms were obtained from Agilent Bioanalyzer with RNA Pico chip assay (Agilent Technologies, Santa Clara, CA, USA)
