Abstract
The gene encoding the transcription factor LEAFY was identified in the genome of the mycoheterotrophic plant, pinesap Monotropa hypopitys. In the transcriptomes of roots, bracts, and flowers of flowering pinesaps, the MhyLFY gene expression was absent. These data suggest the conservativeness of the LFY-dependent mechanism of flower meristem identity and flower formation in heterotrophic species with some differences associated to the specificity of development and the structure of such plants. The pinesap flowering under the control of the transcription factor MhyLFY may be initiated either in an embryonic inflorescence during spring dormancy release of adventitious root buds or in an inflorescence of a growing reproductive stem after photoperiodic induction.
