Primary and Secondary Growth in Roots and Shoots03:02

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.
Determining the Plane of Cell Division02:13

Determining the Plane of Cell Division

Positioning the cell division plane is a critical step during development and cell differentiation, particularly during mitosis when the plane is essential for determining the size of the two daughter cells. The cell division plane is perpendicular to the plane of chromosome segregation, but different types of organisms have different cell division mechanisms to suit their morphology and function.

Meristems and Plant Growth02:36

Meristems and Plant Growth

Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.
Morphogenesis02:19

Morphogenesis

Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Area of Science:

  • Plant developmental biology
  • Comparative genomics
  • Molecular genetics

Background:

  • Arabidopsis thaliana is a model for dicot embryo development, but its embryology is not universally representative.
  • Recent advances in gene cloning and phylogenetics allow for comparative studies of maize and Arabidopsis embryogenesis.
  • Understanding conserved gene functions is crucial for a comprehensive view of plant development.

Purpose of the Study:

  • To compare the expression patterns and functions of key developmental genes (WOX, STM, DRN, CUC) in maize and Arabidopsis.
  • To investigate the conservation and divergence of gene function in axialization during embryogenesis in these two species.
  • To highlight the orthology of embryonic development pathways between monocots and dicots.

Main Methods:

  • Comparative analysis of gene expression domains for WOX, STM, DRN, and CUC families.
  • Review of existing literature on maize and Arabidopsis embryogenesis.
  • Phylogenetic analysis to infer gene orthology and functional conservation.

Main Results:

  • Despite significant differences in axes and symmetry planes during embryogenesis, considerable functional conservation exists for studied genes between maize and Arabidopsis.
  • Specific differences in gene expression and function were identified, reflecting divergent developmental pathways.
  • The study identified conserved roles for WOX, STM, DRN, and CUC genes in establishing embryonic axes.

Conclusions:

  • Plant embryogenesis exhibits both conserved molecular mechanisms and species-specific adaptations.
  • Comparative studies, like this one between maize and Arabidopsis, are essential for understanding the evolution of developmental pathways.
  • Transcription factor function in axialization shows a mix of conservation and divergence across distantly related plant species.
