Research shows that altered plant architecture impacts yield traits in maize, suggesting potential for improved varieties.

This research aims to understand the role of ERECTA genes in maize shoot and inflorescence development.
Identification of ERECTA-like receptors and their ligands in maize
Analysis of meristem activity and architecture in ZmER mutants
Binding assays to evaluate interactions between ZmER1 and EPFL peptides
Assessment of phenotypic changes in mutant lines regarding inflorescence characteristics
ZmER1 is identified as a key regulator of plant architecture
ZmER1 mutants exhibit compact structures with increased kernel row numbers
Binding of ZmER1 to EPFL peptides influences ear development
Weak ZmER1 alleles show enhanced yield traits, indicating potential breeding targets

Liu et al. (2026) studied this question.
