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 a combination of differential display of cDNA‐polymerase chain reaction (PCR) products and microarray analysis. According to BLAST searches the possible functions of identified genes included a histidine‐containing phosphotransmitter, an α‐expansin, a protein with similarity to the gibberellin‐regulated GAST‐1 and a protein with similarity to an Arabidopsis thaliana protein with unknown function.
