<i>Poncirus trifoliata</i> vs. <i>Citrus junos</i> rootstocks: reshaping lemon rhizosphere microecology through microbial and metabolic reprogramming.

ABSTRACT:

Introduction

Trifoliate orange (Poncirus trifoliataL. Raf) and "Ziyang Xiangcheng" (Citrus junos Sieb. ex Tanaka) are the predominant rootstocks for lemon production in China, exhibiting distinct adaptations to soil pH and differential impacts on plant resilience. As pivotal mediators of scion-soil interactions, rootstocks have emerged as key research targets for their regulatory potential in rhizosphere microbial communities and metabolites.

Methods

Pot-cultured systems were established with lemon (Citrus × limon "Eureka") saplings grafted onto trifoliate orange (PTL) and "Ziyang Xiangcheng" (CJL) rootstocks. Integrated metagenomic and GC-MS metabolomic approaches were employed to analyze rhizosphere microbial communities and metabolites.
