Early flower development in Arabidopsis.
The early development of the flower of Arabidopsis thaliana is described from initiation until the opening of the bud. The morphogenesis, growth rate, and surface structure of floral organs were recorded in detail using scanning electron microscopy. Flower development has been divided into 12 stages using a series of landmark events. Stage 1 begins with the initiation of a floral buttress on th...
متن کاملRegulation of Arabidopsis flower development.
Plant development is governed by intrinsic and environmental factors that regulate the identity and activity of meristems, organized tissues of pluripotent "stem" cells, that together determine plant form and architecture. However, little is known about how these factors act at the molecular leve1 to affect meristem identity and function. Genetic studies in Arabidopsis and other plant species s...
متن کاملFlower and fruit development in Arabidopsis thaliana.
The study of flower development has experienced great advances over the last 15 years. The most important landmark was the proposal of the ABC model in which three different functions of overlapping activities account for the development of the four rings of organs of the eudicot flower. Most interestingly, during recent years this simple and elegant model has been broadly accepted and is appli...
متن کاملGenes directing flower development in Arabidopsis.
We describe the effects of four recessive homeotic mutations that specifically disrupt the development of flowers in Arabidopsis thaliana. Each of the recessive mutations affects the outcome of organ development, but not the location of organ primordia. Homeotic transformations observed are as follows. In agamous-1, stamens to petals; in apetala2-1, sepals to leaves and petals to staminoid peta...
متن کاملPhotoperiod regulates flower meristem development in Arabidopsis thaliana.
Photoperiod has been known to regulate flowering time in many plant species. In Arabidopsis, genes in the long day (LD) pathway detect photoperiod and promote flowering under LD. It was previously reported that clavata2 (clv2) mutants grown under short day (SD) conditions showed suppression of the flower meristem defects, namely the accumulation of stem cells and the resulting production of ext...
