Coordination of root growth with root morphology, physiology and defense functions in response to root pruning in Platycladus orientalis.

ABSTRACT:

Introduction

Root pruning is commonly used to facilitate seedling transplantation for the restoration of degraded or damaged ecosystems. However, little is known about how root growth coordinates morphology, physiology and defense functions following root pruning.

Objectives

We aim to elucidate whether and how root growth trades off with defense functioning after pruning.

Methods

Seedlings of Platycladus orientalis, a tree species widely used in forest restoration, were subjected to root pruning treatment. A suite of root growth, morphological and physiological traits were measured after pruning in combination with proteomic analysis.

Results

Root growth was insensitive to pruning until at 504 h with a significant increase of 16.8%, whereas root physiolo
