Polymerase chain reaction (PCR)-based detection strategies were adopted to examine the etiology and vectorship of pear decline in Taiwan (PDTW). 16S rDNA sequences were amplified from total DNAs prepared from PDTW-affected pear trees Pyrus serotina Rehd. cv. Hengshan and pear psyllid Cacopsylla chinensis using PCR. According to the sequence analyses, C. chinensis carried phytoplasmas of two 16S...
First Report of 16SrII-V Phytoplasma Associated with Green Manure Soybean (Glycine max L.) in Taiwan
Several segments (∼20 kbp) of the lime witches' broom (LWB) phytoplasma genome (16SrII group) were sequenced and analysed. A 5.7 kbp segment (LWB-C) included conserved genes whose phylogenetic tree was consistent with that generated using 16S rRNA genes. Another 6.4 kbp LWB phytoplasma genome segment (LWB-NC) was structurally similar to the putative mobile unit or sequence variable mosaic ge...
