Maize root traits associated with soil organic matter (SOM) mineralization were demonstrated to have a heritable genetic basis. We show root length, root diameter and cumulative root-derived C mineralization to be strong predictors of SOM-C mineralization and identify two candidate genes associated with enhanced SOM-C mineralization rates. There is potential to target these genes to enhance release of nutrients from SOM to support crop nutrition within sustainable maize cropping systems.

影响土壤有机质矿化的玉米根的植物遗传基础证据

与土壤有机质 (SOM) 矿化相关的玉米根性状被证明具有可遗传的遗传基础。我们显示根长、根直径和累积根衍生的 C 矿化是 SOM-C 矿化的有力预测因子，并确定了两个与 SOM-C 矿化率增强相关的候选基因。有可能针对这些基因来增强 SOM 中养分的释放，以支持可持续玉米种植系统中的作物营养。
