How cells in a multicellular organism assume their developmental fates and form distinct patterns is a fundamental biological question. To address this question, I studied genetic and molecular regulation of Arabidopsis flower organ formation and identity determination. Specifically, how the expression of floral meristem and floral organ identity gene AGAMOUS (AG) was regionalized during flower organogenesis. A novel AG repressor LARSON (LSN) was previously isolated in a genetic screen. lsn loss-of-function mutations caused precocious expression of AG in the inflorescence meristem and ectopic expression of AG in sepal primordia, resulting in partial homeotic transformation of late inflorescences into floral meristems and strong homeotic transformation of first whorl sepals into carpels. LSN encoded a homeodomain protein that directly bond to AG cis-regulatory elements in vitro. The cis-regulatory elements were conserved in 17 Brassicaceae species. LSN was expressed in a subset of cells located in the peripheral zones of inflorescence and floral meristems. LSN expression was significantly reduced in the sepal and petal primordia in wild-type flowers, indicating that repression of AG in the sepals and petals was independent of LSN transcription. LSN might establish epigenetic AG repression in the ancestral cells in the peripheral zone to specify the identities of descendant cell types in the floral organs. Therefore, floral organ identities were not only dependent upon gene expression in the organs, but were also dependent upon the histories of the cell development. Genetic and molecular analyses showed that LSN acted upstream of a putative repression complex, which, I proposed, was involved in the maintenance of AG repression in flowers. The putative repressive complex consistes of APETALA1 (AP1), LUNIG (LUG) and SEUSS (SEU) known to encode flower specific repressors of AG. Mutations in these three genes enhanced the lsn phenotypes. However, none of their proteins int

The way plants grow and develop organs significantly impacts the overall performance and yield of crop plants. The basic knowledge now available in plant development has the potential to help breeders in generating plants with defined architectural features to improve productivity. Plant translational research effort has steadily increased over the last decade due to the huge increase in the availability of crop genomic resources and Arabidopsis-based sequence annotation systems. However, a consistent gap between fundamental and applied science has yet to be filled. One critical point often brought up is the unreadiness of developmental biologists on one side to foresee agricultural applications for their discoveries, and of the breeders to exploit gene function studies to apply to candidate gene approaches when advantageous on the other. In this book, both developmental biologists and breeders make a special effort to reconcile research on the basic principles of plant development and organogenesis with its applications to crop production and genetic improvement. Fundamental and applied science contributions intertwine and chase each other, giving the reader different but complementary perspectives from only apparently distant corners of the same world.
