The liguleless-1 (lg1) gene is crucial for maize leaf development, controlling ligule and auricle formation. Mutant analysis reveals lg1 acts early and tissue-specifically in epidermal and internal cells for proper leaf structure.

Area of Science:

  • Plant biology
  • Developmental genetics
  • Maize genetics

Background:

  • The liguleless-1 (lg1) gene plays a vital role in maize leaf development.
  • Mutations in lg1 disrupt the formation of ligules and auricles, structures that separate the leaf blade and sheath.

Purpose of the Study:

  • To elucidate the precise timing and cellular location of liguleless-1 (lg1) gene activity during maize leaf development.
  • To understand the tissue-specific functions of the Lg1+ allele in ligule and auricle formation.

Main Methods:

  • Comparative developmental analysis of wild-type and lg1 mutant maize leaves.
  • Genetic mosaic analysis using wild-type and lg1 mutant cell combinations.
  • Microscopic examination of cellular divisions during leaf differentiation.

Main Results:

  • The liguleless-1 (lg1) gene acts early in leaf development, prior to ligule formation, potentially during vascularization.
  • Genetic mosaic studies revealed distinct functions for Lg1+ in the adaxial epidermis (ligule) and internal tissues (auricle).
  • Evidence suggests wild-type internal tissue can induce rudimentary ligule formation in lg1 mutant epidermis.

Conclusions:

  • The liguleless-1 (lg1) gene functions in a tissue-specific manner during the early stages of ligule and auricle initiation in maize.
  • Lg1 exhibits autonomous activity in the epidermis for ligule development and in internal tissues for auricle development.
  • Interactions between epidermal and internal tissues are critical for normal ligule formation, mediated by the lg1 gene.
