| Abstract:
Hop latent viroid (HLVd) is the serious hop plant (Humulus lupulus L.) pathogen which can be detected only by molecular biology methods. Three methods for HLVd detection were compared. The presence of the pathogen was examined by dot-blot hybridization and RT-PCR in the total nucleic acid extracts. HLVd was also detected in fresh plant material by tissue print hybridization. In this method the freshly cut petioles surfaces were pressed onto nylon membrane and after UV-fixing the membrane was subjected to hybridization. DNA digoxigenin-labeled chemiluminescent detected probe was used both in dot-blot and tissue printing hybridization methods. The results indicates that the both hybridization techniques can be useful in routine tests for HLVd detection and that negative signals obtained by these methods have to be checked by RT-PCR. | |
