From: Mapping of Candidate Genes in Response to Low Nitrogen in Rice Seedlings
Phenotype distribution of root morphology traits of 295 rice varieties under low and high nitrogen treatments. A HRD: root diameter under high-nitrogen treatment. LRD: root diameter under low-nitrogen treatment. B HRL: root length under high-nitrogen treatment. LRL: root length under low-nitrogen treatment. C RDR: relative value of root diameter under low and high nitrogen treatments. D RLR: relative value of root length under low and high nitrogen treatments
