与土壤有机质矿化有关的玉米根系性状具有遗传基础。我们发现根长、根径和累积根源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的养分释放，以支持可持续玉米种植系统中的作物营养。
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.
