![]() So it became easier to differentiate between two individual according to their polymorphism DNA. The method appears to be viable for rapid analysis of mycorrhizal communities using pooled root tips collected from soil cores. RFLP show the difference between the individual of one species. Restriction Fragment Length Polymorphism (RFLP) is a technique in which organisms may be differentiated by analysis of patterns derived from cleavage of their. ![]() We found good correspondence between the community distribution patterns, determined by T-RFLP, and the individual morphotype T-RFLP patterns normalized by their QPCR values. DNA extracted from morphotype classes from the same core were pooled, amplified as above, and used to assess abundance of fungal species types within the mixed community and results compared to traditional morphotyping techniques. Restricted labeled amplicon was used to generate terminal restriction fragment lengths on an ABI 310 sequencer to determine molecular identity of colonizing fungi. In conclusion, the presented 16S rRNA gene T-RFLP method is a highly robust. Root tips separated from soil cores were morphotyped according to standard procedures, and DNA was extracted from separate morphotype classes and amplified with a novel set of primers labeled with the fluorescent dyes 6FAM and HEX. This is usually not achieved by current high throughput sequencing protocols. We describe here results of a study conducted to assess the efficacy of a T-RFLP approach for determination of ectomycorrhizal communities colonizing the roots of Loblolly pine (Pinus taeda L.) in North Carolina, U.S.A. Sterile, deionized water, restriction enzyme 10X buffer, Acetylated BSA, DNA sample, EcoRI restriction enzyme. T-RFLP methodology targeting rRNA genes has effectively been used to discriminate between microbial communities but to date has not been used specifically for the analysis of ectomycorrhizal communities colonizing plant roots. Consequently, miscalculation of indicators of community structure (richness, diversity indices, evenness) can occur and the ability to address ecological/ecosystem function questions is curtailed by the high sample time commitment. Depending on the rigor of the classification protocol, this technique can incorrectly assign dissimilar genetic entities into the same morphotype class and is very labor intensive. ![]() Studies of ectomycorrhizal community structure have used a variety of analytical regimens including sole or partial reliance on gross morphological characterization of colonized root tips.
