    Abstract Poinsettia is an important ornamental cultivated worldwide. Commercial poinsettias are almost universally infected with a pathogen known as the poinsettia branch-inducing phytoplasma (PoiBI), which can increase the level of branching in host plants and make the plants more desirable to consumers. Despite PoiBI's crucial role in poinsettia production, little is known about PoiBI-poinsettia interactions in regard to the pathogen's

    Abstract It has long been established that phytoplasma infection is the cause of the free-branching phenotype in poinsettia. However, relatively little is known about the ecology of the pathogen in planta. The present study evaluated the infection pattern of poinsettia branch-inducing phytoplasma (PoiBI) and its association with the poinsettia phenotype during cutting propagation. The presence of this pathogen in the poinsettia variety Luv U Pink was determined using PCR and sequence analysis. The infection density of PoiBI in distinct tissue types of different plant segments were then determined using quantitative PCR coupled with plasmid-based standard curves. Both vegetative-stage and flowering-stage plants were tested. The results showed that, despite being considerably variable among plants, the infection densities of PoiBI tend to be higher in source leaves located in the lower parts of the plant. The densities were consistently lower in tissues located at the top of the plants, regardless of the tissue type. Analysis of the infection densities among samples collected from six stock plants used in commercial production also revealed significantly different levels of PoiBI load. An association between PoiBI infection density in the stock plants and the level of branching in cutting-propagated plants (derived from the stock plants) was also observed; stock plants with low infection densities tended to produce smaller proportions of plants exhibiting higher degrees of branching both before and after pinching. These data suggest that uneven distribution of PoiBI within and among stock plants may lead to the production of cuttings with variable phytoplasma densities which may, in turn, affect the phenotypic uniformity of the plants produced. Overall, findings from the present work add to the understanding of PoiBI's ecology and could provide implications to commercial poinsettia production.

    Abstract 'Candidatus Liberibacter' is a genus of plant-associated bacteria that can be transmitted by insects of the superfamily Psylloidea. Since many members of this genus are putative causal agents of plant diseases, it is crucial in studying their interactions with the psyllid vectors. However, previous studies have mainly focused on few species associated with diseases of economic significance, and this may potentially hinder the development of a more comprehensive understanding of the ecology of 'Ca. Liberibacter'. The present study showed that an endemic psyllid species in Taiwan, Cacopsylla oluanpiensis, is infected with a species of 'Ca. Liberibacter'. The bacterium was present in geographically distant populations of the psyllid and was identified as 'Ca. Liberibacter europaeus' (CLeu), a species which generally does not induce plant symptoms. Analysis of CLeu infection densities in male and female C. oluanpiensis with different abdominal colors using quantitative polymerase chain reaction revealed that CLeu infection was not significantly associated with psyllid gender and body color. Instead, CLeu infection had a negative effect on the body sizes of both male and female psyllids, which is influenced by bacterial titer. Investigation on CLeu's distribution patterns in C. oluanpiensis's host plant Pittosporum pentandrum indicated that CLeu does not behave as a plant pathogen. Also, results showed that nymph-infested twigs had a greater chance of carrying high loads of CLeu, suggesting that ovipositing females and the nymphs are the main source of the bacterium in the plants. This study is not only the first to formally report the presence of CLeu in C. oluanpiensis and plants in the family Pittosporaceae, but also represents the first record of the bacterium in Taiwan. Overall, the findings in this work broaden the understanding of associations between psyllids and 'Ca. Liberibacter' in the field.
