Summary

Maize AGAMOUS homologs ZAG1 and ZMM2 are crucial for floral determinacy and reproductive organ development. Redundancy between ZAG1 and ZMM2 suggests a complex genetic mechanism for C-function organ identity in maize.

Area of Science:

  • Plant Molecular Biology
  • Developmental Genetics
  • Maize Genetics

Background:

  • The Arabidopsis AGAMOUS gene is essential for reproductive organ development and floral determinacy.
  • Understanding floral development in crops like maize is critical for agricultural applications.

Purpose of the Study:

  • To investigate the function of maize AGAMOUS homologs in floral development.
  • To identify genes involved in reproductive organ identity and floral determinacy in maize.

Main Methods:

  • Utilized reverse genetics to isolate transposon-induced mutations in maize AGAMOUS homologs.
  • Analyzed ZAG1 mutants for defects in floral determinacy and organ identity.
  • Identified and cloned a second AGAMOUS homolog, ZMM2, based on expression patterns.

Main Results:

  • ZAG1 mutants displayed a loss of floral determinacy but largely retained reproductive organ identity.
  • Expression patterns of ZAG1 and ZMM2 were distinct.
  • Evidence suggests functional redundancy between ZAG1 and ZMM2 in maize floral development.

Conclusions:

  • Two maize AGAMOUS homologs, ZAG1 and ZMM2, likely orchestrate C-function organ identity.
  • These genes possess overlapping but non-identical functions in floral development.
  • Maize floral organ specification involves a complex interplay between ZAG1 and ZMM2.
