Abstract
Secondary metabolites in mangroves often interfere with RNA extraction yielding poor concentration and quality, which is unsuitable for downstream applications. As existing protocols yielded low-quality RNA from root tissues of Kandelia candel (L.) Druce and Rhizophora mucronata Lam., an optimized method was developed for improving the quality and yield of RNA. Compared with three other methods, this optimized protocol gave better RNA yield and purity for both species. The absorbance ratios were ≥1.9 for A260/280 and A260/230, while RNA integrity number values ranged from 7.5 to 9.6. Results show that our modified method is efficient in obtaining high-quality RNA from mangrove roots and is suitable for downstream experiments such as cDNA synthesis, real-time quantitative PCR and next-generation sequencing.
期刊介绍：
BioTechniques is a peer-reviewed, open-access journal dedicated to publishing original laboratory methods, related technical and software tools, and methods-oriented review articles that are of broad interest to professional life scientists, as well as to scientists from other disciplines (e.g., chemistry, physics, computer science, plant and agricultural science and climate science) interested in life science applications for their technologies.
Since 1983, BioTechniques has been a leading peer-reviewed journal for methods-related research. The journal considers:
Reports describing innovative new methods, platforms and software, substantive modifications to existing methods, or innovative applications of existing methods, techniques & tools to new models or scientific questions
Descriptions of technical tools that facilitate the design or performance of experiments or data analysis, such as software and simple laboratory devices
Surveys of technical approaches related to broad fields of research
Reviews discussing advancements in techniques and methods related to broad fields of research
Letters to the Editor and Expert Opinions highlighting interesting observations or cautionary tales concerning experimental design, methodology or analysis.
