Morphogenesis02:19

Morphogenesis

19.9K
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.

Primary and Secondary Growth in Roots and Shoots

46.5K
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.

Meristems and Plant Growth02:36

Meristems and Plant Growth

36.2K
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.

Seed Structure and Early Development of the Sporophyte02:33

Seed Structure and Early Development of the Sporophyte

27.6K
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.

Mechanism of Lamellipodia Formation01:31

Mechanism of Lamellipodia Formation

3.1K
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...

Zygotic Development And Stem Cell Formation01:10

Zygotic Development And Stem Cell Formation

6.0K
The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...

Background:

  • Plant leaves originate from the shoot apical meristem, forming diverse structures.
  • Leaf development is a complex process influenced by intrinsic and extrinsic factors.

Purpose of the Study:

  • To review recent advances in understanding leaf development.
  • To explore how various factors modulate leaf form diversity.

Main Methods:

  • Literature review of recent research on plant leaf development.
  • Analysis of the roles of plant hormones, transcriptional regulators, and tissue mechanics.

Main Results:

  • Leaf development follows a plastic program adaptable to species, stage, and environment.
  • Diverse leaf forms arise from the interplay of hormonal signals, gene regulation, and mechanical forces.
  • Key processes include leaf initiation, balancing morphogenesis with differentiation, and margin patterning.

Conclusions:

  • Understanding the regulatory networks governing leaf development is crucial for explaining plant form diversity.
  • Future research should focus on integrating hormonal, genetic, and mechanical perspectives.
