Abstract
The isolation of DNA and RNA from the leafy gametophyte (thallus) of red algal seaweeds such as Porphyra is still a challenge because of the high content of polysaccharides. Further molecular analysis, including restriction enzyme digestion, polymerase chain reaction (PCR), and reverse transcription (RT), could be interfered by the remaining trace amount of polysaccharides. Various protocols have been developed for molecular biological studies of Porphyra species to avoid polysaccharide contamination. Here, we compare different methods in DNA and RNA isolation from the thallus of Porphyra umbilicalis. The quality of the resulting DNA for restriction enzyme digestion and PCR and the quality of RNA for RT and RT-PCR were analyzed with PuActin3, a P. umbilicalis homolog of Porphyra yezoensis Actin3 gene, which is a potential marker for monitoring thallus maturation. Our results show that the polysaccharides could be simply, but efficiently, removed from DNA by coprecipitation with potassium acetate, and RNA could be purified from polysaccharides by a single step of lithium chloride precipitation. We successfully utilized the RNA preparation for the rapid amplification of cDNA ends to amplify the unknown upstream flanking region, including the 5′-UTR, of PuDnm1, a P. umbilicalis homolog of the Cyanidioschyzon merolae mitochondrial division gene Dnm1, and locate the putative transcription start point at −162 bp from the translation initiation site (A of the ATG codon). Our work provides a simplified basic workflow for the future molecular cloning work on the gametophyte phase of P. umbilicalis and can be adopted easily for other polysaccharide-rich seaweeds.
