These tests often need several days or weeks to complete and are frequently<br />unspecific. Molecular identification mostly implies sequencing, which is relatively expensive and<br />time-consuming, as well as impractical for large numbers of isolates. The Rolling Circle<br />Amplification approach, known as RCA, is a quick, critical and economic method for fungal species'<br />identification. Despite its high speed, this method is highly sensitive, and it has been widely used for<br />the detection of pathogenic fungi. The specific probes are designed based on the differences in the<br />nucleotide regions of the target gene for the target species. The amplification product can be<br />visualized by agarose gel electrophoresis, but can also be visualized in gel-free systems using<br />fluorescence staining of the amplified product by SYBR Green in combination with a UV<br />transilluminator. Thus, the simplicity, sensitivity, robustness and low costs make RCA an attractive<br />technique for the reliable identification of sibling species and other closely related fungi. https://jmr.ut.ac.ir/article_51633_79ef0527e818b60dec21d143a1aeaee2.pdf
