Primary and Secondary Growth in Roots and Shoots03:02

Primary and Secondary Growth in Roots and Shoots

57.7K
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.

Multipotency and Niche of Bulge Stem Cell

3.8K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Water and Mineral Acquisition

33.4K
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.

Meristems and Plant Growth

46.4K
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.

Overview of Regeneration and Repair01:19

Overview of Regeneration and Repair

4.2K
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

Morphogenesis02:19

Morphogenesis

28.7K
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 Biology
  • Root Development
  • Plant Immunity

Background:

  • Roots are organized tissues with diverse cell types governed by cell identity networks.
  • Roots face significant disease threats and have robust immune systems.
  • Immune responses in plants are triggered by molecular signals during microbial attacks.

Purpose of the Study:

  • To review the interdependence of root development and immunity.
  • To explore how cell-specific immunity is regulated by developmental processes.
  • To highlight the role of developmental age in root immunity outcomes.

Main Methods:

  • This review synthesizes existing research on root development and immunity.
  • It analyzes the molecular mechanisms linking cell identity, development, and immune signaling.
  • The study examines how cross-talk between development and immunity affects root responses.

Main Results:

  • Root development and immunity are intricately linked, with immunity activation potentially inhibiting growth.
  • Cell types mount specific immune responses based on their developmental roles.
  • Fundamental developmental processes contribute to efficient and diverse immune strategies.

Conclusions:

  • The developmental age and cell-specific functions of root cells are critical for modulating immunity.
  • Understanding this development-immunity cross-talk is key to improving plant disease resistance.
  • This interplay ensures cost-effective and efficient immune responses in plant roots.
