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.

Mechanism of Lamellipodia Formation01:31

Mechanism of Lamellipodia Formation

Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...
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.
Water and Mineral Acquisition02:34

Water and Mineral Acquisition

Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.
Seed Structure and Early Development of the Sporophyte02:33

Seed Structure and Early Development of the Sporophyte

Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

Area of Science:

  • Plant biology
  • Developmental biology
  • Genetics

Background:

  • Plant root systems are essential for growth and development.
  • Lateral roots emerge post-embryonically from pericycle cells.
  • Lateral root organogenesis involves asymmetric cell division.

Purpose of the Study:

  • To summarize recent advances in understanding lateral root initiation.
  • To highlight the roles of auxin and cell cycle activity.
  • To elaborate on the key steps: pericycle cell priming, founder cell establishment, and asymmetric cell division.

Main Methods:

  • Review of recent scientific literature.
  • Focus on molecular and cellular mechanisms.
  • Synthesis of findings into a tentative model.

Main Results:

  • Auxin and cell cycle activity are prominent regulators.
  • Pericycle cell priming is an initial key step.
  • Founder cell establishment and asymmetric division follow.

Conclusions:

  • A tentative model for lateral root initiation is proposed.
  • Successive auxin response modules are crucial.
  • Additional regulatory factors provide layers of control.
