Simultaneous Detection of Two Viroids Infecting Grapevines in Taiwan by Multiplex RT-PCR
Results of this work demonstrated the potential of multiplex reverse-transcription polymerase chain reaction (RT-PCR) technique for detecting Hop stunt viroid (HSVd) and Grapevine yellow speckle viroid-1 (GYSVd-1) simultaneously in naturally infected grapevines. A total of one hundred grapevine leaf...
