Title

WOX5 expression stimulated by the transcription factor NF-YAc reprograms cortical cells for nodule primordium initiation in soybean

Linfang Li; Yifu Chen; Runxin Zhu; et al. Journal of Experimental Botany 2026. doi:10.1093/jxb/erag051

Other claims from this paper (9)

Observation WOX5 is activated by rhizobia specifically in cortical cells that give rise to nodule primordia in soybean.
Intervention effect Knockout of the three WOX5 homologs reduced nodule number in soybean.
Intervention effect Knockout of the three WOX5 homologs attenuated nitrogenase activity in soybean.
Mechanism The reduced nodule number in wox5abc mutants is attributable to a decrease in primordium density.
Observation A 442 bp legume-specific fragment of the WOX5a promoter is necessary and sufficient for primordium-specific expression.
Mechanism NF-YAc directly binds the WOX5a promoter fragment and activates expression of WOX5a.
Intervention effect Loss of NF-YAc phenocopies the wox5abc mutant in soybean.
Intervention effect NF-YAc overexpression fails to rescue nodulation in wox5abc mutants.
Mechanism NF-YAc-mediated activation of WOX5 initiates a de novo stem-cell niche in root cortical cells.
