Sequences have been deposited in GenBank, accessions FJ435156 to FJ435166. Ori for discussions and sharing results before publication. ![]() Rameau for their comments on the manuscript and N. The results support the following causal sequence of events: (1. Measurements of tissue elasticity at various depths showed that, at the site of incipient primordia, the first increases occurred in subepidermal tissues. Nature Genetics Shoot apical meristems are stem cell niches that balance proliferation with the incorporation of daughter cells into organ primordia. Kramer, and the Tomato Genetics Resource Centre for providing material the Cell Biology Laboratory gardener team for their plant care J. The aerial organs of plants are formed at the shoot apical meristem following a specific phyllotactic pattern 10. is a recipient of a Royal Society Research Fellowship. Here we report FASCIATED EAR3 (FEA3), a leucine-rich-repeat receptor that functions in stem cell control and responds to a CLAVATA3/ESR-related (CLE) peptide expressed in organ primordia. is supported by the UK Biotechnology and Biological Sciences Research Council and the Gatsby Charitable Foundation and is the recipient of a European Molecular Biology Organization young investigator award and a Royal Society Wolfson Merit award. Signals that provide feedback from organ primordia to control the stem cell niche in plants have also been hypothesized, but their identities are unknown. was supported by the Fundacíon Española para la Ciencia y la Tecnología (Ministerio de Ciencia e Innovacíon) and the Région Ile-de-France. The subsequent divisions of neighboring cells result in the bulging of a new organ primordium in an established position in reference to existing (older). fellowship from the Ministère de l'Enseignement Supérieur et de la Recherche, and A.P. This work was partly supported by an Action Concertée Incitative “Jeunes Chercheuses et Jeunes Chercheurs” and the trilateral Génoplante GENOSOME program TRIL-046. Based on boundary-specific expression patterns and mutant defects in boundary formation, organ separation, SAM initiation and maintenance, branching, or floral organ patterning, several transcription factors have been identified as important boundary regulators, including CUP-SHAPED COTYLEDONS 1, 2 and 3 (CUC1, CUC2, CUC3), LATERAL SUPPRESSOR (LAS), LATERAL ORGAN BOUNDARIES (LOB), JAGGED LATERAL ORGANS (JLO), LATERAL ORGAN FUSION (LOF), HANABA TARANU (HAN), SUPERMAN (SUP) and RABBIT EARS.
