Comparison and improvement of RNA extraction methods in Sargassum (Phaeophyta)
© 2023 Phycological Society of America..
Sargassum (Sargassaceae) is widely distributed globally and plays an important role in regulating climate change, but the landscape of genomes and transcripts is less known. High-quality nucleic acids are the basis for molecular biology experiments such as high-throughput sequencing. Although extensive studies have documented methods of RNA extraction, these methods are not very applicable to Sargassum, which contains high levels of polysaccharides and polyphenols. To find a suitable method to improve the quality of RNA extracted, we compared and modified several popular RNA extraction methods and screened one practical method with three specific Sargassum spp. The results showed that three CTAB methods (denoted as Methods 1, 2, and 3) and the RNAprep Pure Plant Kit (denoted as Method 4) could, with slight modifications, effectively isolate RNA from Sargassum species, except for Method 4 used with S. fusiforme. By performing further screening, we determined Method 4 was the best choice for S. hemiphyllum and S. henslowianum, as revealed by RNA yields, RNA Integrity Number (RIN), extraction time, and unigene mapped ratio. For S. fusiforme, Methods 1, 2, and 3 showed no obvious differences among the yields, quality, or time to perform. In addition, one other method was tested, but we found the quality of the RNA extracted by TRIzol reagent methods (denoted as Method 5) performed the worst when compared with the above four methods. Therefore, our study provides four suitable methods for RNA extraction in Sargassum and is essential for future genetic exploration of Sargassum.
