Flower 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 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...
متن کاملAntiquity and evolution of the MADS-box gene family controlling flower development in plants.
MADS-box genes in plants control various aspects of development and reproductive processes including flower formation. To obtain some insight into the roles of these genes in morphological evolution, we investigated the origin and diversification of floral MADS-box genes by conducting molecular evolutionary genetics analyses. Our results suggest that the most recent common ancestor of today's f...
متن کاملEvolution of Gene Regulatory Networks Controlling Body Plan Development
Evolutionary change in animal morphology results from alteration of the functional organization of the gene regulatory networks (GRNs) that control development of the body plan. A major mechanism of evolutionary change in GRN structure is alteration of cis-regulatory modules that determine regulatory gene expression. Here we consider the causes and consequences of GRN evolution. Although some G...
متن کاملA Genetic Analysis of Chloroplast Division and Expansion in A rabidopsis thaliana ' Kevin
A nuclear recessive mutant of Arabidopsis thaliana, arc5, has been isolated in which there is no significant increase in chloroplast number during leaf mesophyll cell expansion and in which there are only 13 chloroplasts per mesophyll cell compared with 121 in wild-type cells. Mature arc5 chloroplasts in fully expanded mesophyll cells are 6-fold larger than in wild-type cells. A large proportio...
