Molecular characterization of endophytes isolated from Saccharum spp based on esterase and ribosomal DNA (ITS1-5.8S-ITS2) analyses
This study used esterases and ribosomal DNA (rDNA) markers to determine endophytic variability in order to better understand endophyte-host interactions. Polyacrylamide gel electrophoresis and esterase isoenzymes (EST; EC 3.1.1.3), with α-naphthyl acetate and β-naphthyl acetate as substrates, were used to assess relationships among endophytes. ITS1-5.8S-ITS2 sequencing data were used as rDNA markers. Thirty-two esterases were obtained from 37 isolates of Saccharum spp, which clustered into five endophyte groups.
