Improved and convenient method of RNA isolation from polyphenols and polysaccharide rich plant tissues.

Isolation of high-quality RNA from a wide range of woody plants

Isolation of high-quality RNA is one of the most crucial methods in molecular biology. RNA extraction from woody plants has been problematic due to the presence of rigid and woody tissues, large amounts of polysaccharides, polyphenols and other secondary metabolites. Here we present a suitable protocol for RNA isolation from a wide range of woody plants that includes eight gymnosperms and four ...

High Quality RNA Isolation from Leaf, Shell, Root Tissues and Callus of Hazelnut (Corylus avellana L.)

Extraction of high quality RNA is a critical step in molecular genetics studies. Hazelnut is one of the most important nuts plants in the world. The presence of the taxol and other taxanes in hazelnut plant necessitates explaining their biosynthesis pathway and identifying the candidate genes. Therefore, an easy and practical method is necessary for RNA extraction from hazelnuts. Hazelnut has h...

Isolation of total RNA from tissues rich in polyphenols and polysaccharides of mangrove plants

RNA extraction from mangrove tissues can be difficult due to the presence of polyphenolic and polysaccharide compounds upon cell disruption. Besides, a successful RNA isolation from mangrove tissues sometimes can be strain and species specific. Two different methods were used to extract RNA from tissues (stems, leaves and roots) of black mangrove (Avicennia germinans) and white mangrove (Lagunc...

Efficient protocol for isolation of functional RNA from different grape tissue rich in polyphenols and polysaccharides for gene expression studies

Extraction of RNA from plant tissue containing high levels of polyphenols and polysaccharides is tedious and difficult in grapes. Although several protocols have been published for plant RNA isolation, most have failed to yield high quality RNA in sufficient quantity from mature and diseased grape tissue. We describe a protocol for isolating intact and high quality RNA from various grape tissue...
