Aerenchyma is continuous gas space between shoot and roots that contributes to the internal aeration in plants. In response to excess water stress and the plant hormone ethylene, maize (Zea mays) forms aerenchyma in root cortical cells by programmed cell death (PCD). The aim of this study was to understand the molecular mechanism of ethylene-induced aerenchyma formation by identifying genes that are up- or down-regulated by ethylene treatment in the maize root cortical cells isolated by laser microdissection. Overall design: Gene expression analysis in cortical cells of maize primary root
