Reproductive meristem fates in Gerbera.
Flowering plants go through several phases between regular stem growth and the actual production of flower parts. The stepwise conversion of vegetative into inflorescence and floral meristems is usually unidirectional, but under certain environmental or genetic conditions, meristems can revert to an earlier developmental identity. Vegetative meristems are typically indeterminate, producing orga...
متن کاملETTIN patterns the Arabidopsis floral meristem and reproductive organs.
ettin (ett) mutations have pleiotropic effects on Arabidopsis flower development, causing increases in perianth organ number, decreases in stamen number and anther formation, and apical-basal patterning defects in the gynoecium. The ETTIN gene was cloned and encodes a protein with homology to DNA binding proteins which bind to auxin response elements. ETT transcript is expressed throughout stag...
متن کاملFlower Development in Gerbera Hybrida, Asteraceae
As a genetically determined structure, flower is an attractive object for developmental studies in plants. Flower development provides a good system for understanding cell differentiation and genetic mechanisms needed for organogenesis. The current molecular view on flower development has been based on studies on relatively few model species, like Arabidopsis and Antirrhinum. Research in model ...
متن کاملTemporal and spatial domain-specific transcriptomic analysis of a vital reproductive meristem in Arabidopsis thaliana
Background Plant meristems are analogous to animal stem cell niches as they maintain a pool of undifferentiated cells that divide and differentiate to give rise to organs. The carpel margin meristem is a vital, multi-potent structure located in the medial domain of the Arabidopsis thaliana gynoecium, the female floral reproductive organ. The carpel margin meristem generates ovules that upon fer...
متن کاملThe TERMINAL FLOWER2 (TFL2) gene controls the reproductive transition and meristem identity in Arabidopsis thaliana.
A new mutant of Arabidopsis thaliana that initiates flowering early and terminates the inflorescence with floral structures has been identified and named terminal flower2 (tfl2). While these phenotypes are similar to that of the terminal flower1 (tfl1) mutant, tfl2 mutant plants are also dwarfed in appearance, have reduced photoperiod sensitivity and have a more variable terminal flower structu...
