Although the CTAB method has eliminated some specific problems, e.g., low pH in raw fruit or high levels of polysaccharides, oligosaccharides and phenolics in raw and ripe fruits, the total time required is long and unsuitable for high throughput. Here, we successfully modified this CTAB protocol to isolate good-quality RNA from (i) fleshy fruits, especially raw and ripe mangos; (ii) the leaves of a succulent air plant; and (iii) an oligosaccharide-rich onion epidermis. This RNA proved useful for downstream transcriptomic applications, where RT-PCR followed by RACE yielded the complete open reading frame of the (mango) terpene synthase gene. We also extended the utility of this protocol to co-isolate good-quality genomic DNA from the supernatant that remained after RNA precipitation. This preparation was useful for the arbitrary primer multilocus amplification of genomic DNA as well as for single locus diversity marker amplifications of the ctDNA and mtDNA.</p>10aDNA-RNA co-isolation10afleshy fruit10aMango10aoligosaccharide-rich10aRipening10atranscriptomic studies1 aPandit, Sagar, Subhash1 aMitra, Sirsha, Sribas1 aGiri, Ashok, P.1 aGupta, Vidya, Shrikant  uhttps://library.ncl.res.in/content/quick-method-isolating-rna-raw-and-ripe-fleshy-fruits-well-co-isolating-dna-and-rna
