What this paper is about
This study investigated mature ear traits along with the activity of the female inflorescence meristem (IM) using a Teosinte‑Maize introgression (TM) population via measuring the IM size, and found that qIM3 is involved in several hormone-mediated pathways and meristem development.

BACKGROUND: The ear of maize is a highly domesticated organ that has undergone a substantial increase in volume compared to its wild ancestor teosinte, resulting in a significant yield enhancement in modern cultivated maize. Application of quantitative trait loci (QTLs) mapping using the maize-teosinte segregation population facilitated the identification of more potential favorable variations for utilization in cultivation. However, the mature ear traits of the maize-teosinte population are influenced by genetic introgression from teosinte, which poses significant challenges to the investigation of yield-related traits due to abnormal sex differentiation of the inflorescence at the immature ear stage. RESULTS: This study investigated mature ear traits along with the activity of the female inflorescence meristem (IM) using a Teosinte‑Maize introgression (TM) population via measuring the IM size. A total of 32 QTLs were detected across multiple environments over several years, with individual QTLs explaining 5.18% to 21.48% of the phenotypic variation. Notably, a major pleiotropic QTL regulating IM size and many ear traits was identified and narrowed to a 3.64 cM genetic interval on chromosome 3, namely qIM3. One candidate gene encoding ZmEREB147 (Zm00001d043205) was identified with the help of transcriptome data, and Gene Ontology (GO) analysis demonstrated that qIM3 is involved in several hormone-mediated pathways and meristem development. CONCLUSIONS: The rapid implementation of these findings in maize molecular breeding holds important potential application value and provides broad prospects for improving maize yield.
