잔디병 원인균의 DNA 정보 분석을 위한 분자표지 확인 과정은 다음과 같다. 이병 잔디 조직 등을 현미경 관찰 후 배지에서 곰팡이 원인균을 분리동정하였다. 동정 후 배양된 원인균에서 DNA를 추출하여 재확인 절차를 걷쳤다. 만약에 원인균 배양이 불가능할 경우 감염된 시료에서 DNA를 추출하였다. The molecular marking confirmation process for DNA information analysis of the causative bacteria of grass diseases is as follows. The microorganism was isolated and identified in the medium. After the identification, DNA was extracted from the cultured causative bacteria and the procedure was reaffirmed. If the causative organism was not possible, DNA was extracted from infected samples.

유전자 증폭기를 이용하여 DNA별 분자표지의 증폭정도를 확인하고, 궁극적으로는 각각의 증폭량을 수치화하여 원인균 밀도 변화량을 확인하였다(도 1 내지 6 참조). The degree of amplification of the molecular markers for each DNA was confirmed using a gene amplifier, and ultimately, the amplification amount of each DNA was quantified to confirm the change in the causative bacteria density (see FIGS. 1 to 6).
