Tomato Flower Abnormalities Induced by Stolbur Phytoplasma Infection Are Associated with Changes of Expression of Floral Development Genes

Molecular Plant-Microbe Interactions, 2006
Tomato (Lycopersicon esculentum cv. Micro-Tom) plants infected by the stolbur phytoplasma (isolate PO) display floral abnormalities, including sepal hypertrophy, virescence, phyllody, and aborted reproductive organs, which are reminiscent of those ...

Detection and Molecular Characterization of Phytoplasma Associated with Coconut Yellow Decline [PDF]

, 2009
Phytoplasmas have been detected and characterized by molecular methods in coconut palm (Cocos nucifera L.) for the first time in Malaysia. Polymerase chain reaction (PCR) assays were used to determine whether a phytoplasma is associated with a yellow ...
