Apoptosis-like programmed cell death occurs in procambium and ground meristem of pea (Pisum sativum) root tips exposed to sudden flooding

BACKGROUND AND AIMS: Pea (Pisum sativum) primary roots form long vascular cavities when grown under wet or flooded conditions at 25 °C. It is thought that the cavities are a form of aerenchyma. At 25 °C short roots continue to grow after flooding. After roots reach 10 cm long flooding causes rapid c...
