Bio-Synthesis's Direct Fungi DNA Isolation Kit provides a rapid method for the isolation and purification of total DNA from the fungi found on the surface of symptomatic plant samples. The major benefit of this kit is that it does not require the use of physical homogenization steps to isolate the fungal DNA, which are often time consuming and tedious procedures that are not suitable methods for use in the analysis of large numbers of samples. Furthermore, in the area of pathogen diagnosis simple and convenient sample preparation steps are a critical factor in supporting high throughput analysis. Therefore, Bio-Synthesis's Direct Fungi DNA Isolation Kit adopts a simple and rapid sample preparation procedure that does not rely on physical homogenization steps to isolate sufficient amounts of high quality fungal DNA that can be used in sensitive downstream detection methods.
Purification is based on spin column chromatography using Bio-Synthesis's proprietary resin as the separation matrix. Briefly, the surface fungus is extracted from the plant tissue of interest by shaking with a small volume of Collection Solution. The collected fungi are then lysed, and the released fungal DNA is bound to Bio-Synthesis's column (BIND). Under these conditions only the DNA will bind to Bio-Synthesis's resin while most of the contaminating RNA and cellular proteinaceous components are removed in the flowthrough. The bound DNA is then washed to remove any remaining impurities (WASH). Lastly, the purified DNA is eluted into 50 - 100 µL of the provided Elution Buffer or water (ELUTE). Please see procedure flowchart to the right.

| Figure 1. PCR Amplification of Fungal Pathogens from Grapes for Sequencing Analysis. Total DNA was isolated from the surface of two symptomatic grapes using Bio-Synthesis's Direct Fungi DNA Isolation Kit. Next, 2 µL of the 50 µL elutions were subsequently used as the template in end-point PCR reactions using universal primers for the fungal ITS region. For analysis 10 µL of the PCR products were loaded on the 1% agarose gel above. The bands were extracted by Bio-Synthesis's DNA Gel Extraction Kit (Cat. 13100 ) for sequencing analysis. Through sequencing it was determined that DNA was successfully isolated and amplified from 7 different fungal species including A. niger (Lane 1), C. cladosporiodes (Lane 2), B. cinerea (Lane 3), M. racemosus (Lane 4), A. tenuissima (Lane 5), Penecillium sp. (Lane 5), F. oxysporum (Lane 6) and R. oryzae (Lane 7). Lane C is the non-template control and Lane M is Bio-Synthesis's PCRSizer DNA Ladder. |

| Figure 2. Specific Detection of Botrytis cinerea Infection using Real-time PCR. Fungal DNA was isolated from 5 different varieties of symptomatic grape berries randomly sampled in a vineyard using Bio-Synthesis's Direct Fungi DNA Isolation Kit. The isolated DNA was then used in a real-time PCR reaction for the specific detection of Botrytis cinerea infection. Briefly, 2 µL of DNA from each 50 µL elution was mixed in 20 µL of total PCR reaction buffer and real-time PCR was performed. From observing the graph above, the real-time PCR was able to identify Botrytis infection from the Cabernet Sauvignon and the Viognier grapes, indicate that the quality of DNA isolated from Direct Fungi DNA Isolation Kit is suitable for any downstream application. |
