Integrated Transcriptomic and Phenotypic Analyses Reveal Tissue-Specific Nitrogen Responses and Candidate Genes for Low-Nitrogen Tolerance in Sorghum
The A allele (Hap1) was significantly associated with increased plant height, SPAD value, grain number, nitrogen accumulation, nitrogen accumulation, and biomass under LN stress, suggesting that SORBI_3001G116400 as a candidate gene requiring functional validation and testing in additional genetic backgrounds.
