... regulator FLOWERING LOCUS T . The receptor-like kinase ERECTA is a global positive regulator of cantil formation; therefore, cantils never form in the Arabidopsis strain L er . ERECTA functions genetically upstream of heterotrimeric G proteins. Cantil expressivity is repressed by the specific heterotrimeric...

... replenishment versus cell incorporation into organ primordia. The WUSCHEL (WUS)/CLAVATA (CLV) negative feedback loop is central to SAM size regulation. Its correct function depends on accurate spatial expression of WUS and CLV3 . A signaling pathway, consisting of ERECTA family (ERf) receptors and EPIDERMAL...

.... CHAL is similar in sequence to the putative stomatal ligands EPF1 and EPF2 and, like the EPFs, can reduce or eliminate stomatal production when overexpressed. However, CHAL and the EPFs have different relationships to TMM and the ERECTA (ER) family receptors. We propose a model in which CHAL...

... LEAVES1 ( AS1 ) and ASYMMETRIC LEAVES2 ( AS2 ) genes are two key regulators of leaf polarity. In this work, we demonstrate a new function of the AS1 and AS2 genes in the establishment of adaxial-abaxial polarity by analyzing as1 and as2 alleles in the Landsberg erecta (L er ) genetic background. We...
