Plants generally enhance their root growth in the form of greater biomass and/or length to boost nutrient uptake response short-term low nitrogen (LN). However, underlying mechanisms LN-mediated remain largely elusive. Our genome-wide association study, haplotype analysis, and phenotyping transgenic plants showed that crucial nitrate signaling component NIN-LIKE PROTEIN3.2 (ZmNLP3.2), a positive regulator biomass, is associated with natural variations maize (Zea mays L.) seedlings under LN....
Summary How carbon (sucrose) and nitrogen (amino acid) accumulation is coordinatively controlled in cereal grains remains largely enigmatic. We found that overexpression of the strigolactone (SL) biosynthesis gene CAROTENOID CLEAVAGE DIOXYGENASE 8 ( CCD8 ) resulted greater ear diameter enhanced sucrose amino acid maize kernels. Loss ZmCCD8 function reduced kernel growth with lower sugar concentrations. Transcriptomic analysis showed down‐regulation transcription factors ZmMYB42 ZmMYB63...
