title: Stem cell maintenance in shoot apical meristems.
abstract: Stem cell homeostasis in shoot apical meristems of higher plants is regulated through a dynamic balance between spatial regulation of gene expression, cell growth patterns and patterns of differentiation. Cell-cell communication mediated by both the local factors and long-range signals have been implicated in stem cell homeostasis. Here we have reviewed recent developments on spatio-temporal regulation of cell-cell communication processes with an emphasis on how ubiquitously utilized signals such as plant hormones function with local factors in mediating stem cell homeostasis. We also provide a brief overview of how the activity of ubiquitously utilized epigenetic regulators are modulated locally to orchestrate gene expression.
