About this document
Root Adaptations to Low Oxygen Soils by Fressia is a document available to read on EtoBox.
This document summarizes recent findings about how plants adapt to low oxygen availability in soils caused by flooding. Key adaptations discussed include: 1) Constitutive aerenchyma formation in roots is regulated by auxin signaling pathways involving proteins like AUX/IAA and ARF that stimulate transcription factors regulating aerenchyma initiation. 2) A large cortex-to-stele ratio in roots enhances internal aeration and the diffusion of oxygen along roots, enabling deeper penetration in anoxic soils.
