Soil factors enhance amino acid and peptide accumulation in tuberous roots of <i>Pseudostellaria heterophylla</i>.

ABSTRACT:

Introduction

Pseudostellaria heterophylla (PSH) is a renowned medicinal and culinary plant. However, soil-related factors limiting in the improvement of its yield and quality in practice remain poorly understood.

Methods

We sampled two PSH varieties and their associated rhizosphere soils from two sites in Ningde City, Fujian Province, China, including Chouling village (Z) and Wuyang village (W), to analyze the basic soil physicochemical properties, soil bacterial communities, and untargeted metabolomics of both soils and tuberous roots samples.

Results

Our results showed that the rhizosphere soil at site Z had significantly higher concentrations of calcium (Ca), magnesium (Mg), manganese (Mn), available phosphorus (AP), and available potassium (AK), but a lower
