Phytoplasma induced changes in gene expression in poinsettia
Phytoplasma infection causes a desirable branching phenotype in the ornamental plant Euphorbia pulcherrima by releasing apical dominance. Four E. pulcherrima genes specifically regulated during phytoplasma infection were identified using differential display of cDNA-PCR products. According to BLAST searches the possible functions of the identified genes included a histidinecontaining phosphotra...
متن کاملTransmission of Branch-inducing Phytoplasma PoiBI from Poinsettia (Euphorbia pulcherrima) to Crown-of-thorns (E. milii)
Phytoplasma PoiBI is responsible for free branching in poinsettia (Euphorbia pulcherrima Wild. ex. Klotzsch). In this study, PoiBI was transmitted by dodder from poinsettia to crown-of-thorns (E. milii Des Moulins) in one out of ≈100 attempts, whereas grafting transmission was unsuccessful. PoiBI was shown to be viable in E. milii, as it was detected in the recipient plant and in its cuttings o...

Poinsettia (Euphorbia pulcherrima) is a pot plant, which its colorful bracts form in short days. In order to increase the marketability of this plant, effect of spraying different concentrations of 2-chloroethyl-N, N, N-trimethyl-ammonium chloride (cycocle) growth retardant on the vegetative growth and flowering characteristics of poinsettia was investigated. The experiment was arranged in a co...
متن کاملExperimental Study of Anticonvulsive Effects of Euphorbia Pulcherrima in Mice
Background: Euphorbia pulcherrima belongs to the family: Euphorbiaceae and Genus: Euphorbia. Many species of Euphorbia have been reported as having beneficial properties like anticonvulsive effect. However, little study has been done and published on Euphorbia pulcherrima (Lalupate). In the present study we evaluated the anticonvulsant properties of Euphorbia pulcherrima by using various convul...
متن کاملOverexpression of the AtSHI Gene in Poinsettia, Euphorbia pulcherrima, Results in Compact Plants
Euphorbia pulcherrima, poinsettia, is a non-food and non-feed vegetatively propagated ornamental plant. Appropriate plant height is one of the most important traits in poinsettia production and is commonly achieved by application of chemical growth retardants. To produce compact poinsettia plants with desirable height and reduce the utilization of growth retardants, the Arabidopsis SHORT INTERN...
