Abstract:

Heteroduplex mobility assay (HMA) is based on the principle that DNA heteroduplexes formed between related sequences have a reduced mobility in polyacrylamide gels proportional to their degree of divergence. HMA has been reported as a reliable means for identification and classification of phytoplasmas. Recently, the 16/23S spacer region has been demonstrated to be the best choice, when using the heteroduplex mobility assay (HMA) to differentiate closely related phytoplasmas and to group field isolates into well characterized phytoplasmas. The rice samples of varieties BPT 5204, White Ponni, CO 39 and ADT 43 produced no heteroduplex with assay, signifying that they are very closely related to each other.


Keywords: Candidatus Phytoplasma, mycoplasma-like organisms, heteroduplex
