Genbank accession number

• Multiple experiments demonstrated that transcription factors NAC29/31 and MYB61 are CESA regulators in rice; NAC29/31 directly regulates MYB61, which in turn activates CESA expression
• MYB61 is regulated by GRF4 and promotes nitrogen utilization and biomass production in rice
• The indica allele of MYB61 displays robust transcription resulting in higher NUE and increased grain yield at reduced N supply than that of japonica
• The variation at MYB61 has been selected during indica and japonica domestication
• Here, via quantitative trait loci analysis and map-based cloning, we reveal that natural variation at the MYB61 locus leads to differences in N use and cellulose biogenesis between indica and japonica subspecies of rice

• IIP4, MYB61~OsMYB61, An uncanonical CCCH-tandem zinc finger protein represses secondary wall synthesis and controls mechanical strength in rice., Gene expression and transactivation activity assays revealed that IIP4 negatively regulates expression of MYB61 and CESAs without binding to the promoters of these genes
• MYB61~OsMYB61, OsSND2, OsSND2, a NAC family transcription factor, is involved in secondary cell wall biosynthesis through regulating MYBs expression in rice, We used an electrophoretic mobility shift assay (EMSA) and chromatin immunoprecipitation analysis (ChIP) to further confirm that OsSND2 can directly bind to the promoter of OsMYB61 both in vitro and in vivo
