Abstract excerpt
BACKGROUND AND AIMS: The maize (Zea mays L.) root system is crucial for nitrogen (N) acquisition, yet the genetic mechanisms underlying its adaptive response to low N remain poorly understood. This study aims to dissect the genetic basis of low-N-responsive root traits during the early growth stage and examine their natural variation across maize subpopulations. METHODS: We evaluated six root and two shoot traits...
