Leafy and bulbil development

LEAFY and bulbil development in Titanotrichum (Gesneriaceae)

SEM images of a developping flower (top) and bulbils (bottom) of Titanotrichum oldhamii (Gesneriaceae)Titanotrichum (Gesneriaceae): The Gesneriaceae homologue of the meristem identity gene FLORICOLA (FLO) isolated from Antirrhinum, GFLO was used to investigate meristem behaviour in Titanotrichum in relation to its bulbil development, a unique structure in Titanotrichum that allows the formation of numerous clonal propagules by vegetative means. These bulbils play a key role in the survival of this threatened species.
