  1. aFor the abbreviations of the traits reported previously, five seedling root traits generated under low nitrogen (LN) or high nitrogen (HN) conditions (MARL, ARL, AARL, ARN, and LRL) [42] and three traits associated with water stress responses (LTD, RSFW, and RSDW) [36] are included. MARL, ARL, AARL, ARN, and LRL represent maximal axial root length, axial root length, average axial root length, axial root number, and lateral root length, respectively. LTD, RSFW, and RSDW represent leaf temperature differences, shoot fresh weight, and shoot dry weight, respectively
