Cells Coordinate Growth and Proliferation02:36

Cells Coordinate Growth and Proliferation

4.6K
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

Determining the Plane of Cell Division02:13

Determining the Plane of Cell Division

3.5K
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.

In animal cells, the cleavage furrow forms along the plane of cell division...

Molecular Factors Affecting Cell Division01:27

Molecular Factors Affecting Cell Division

3.4K
Several external and internal factors influence the initiation and inhibition of cell division. For instance, the death of nearby cells or the release of human growth hormone (hGH) promotes cell division. In contrast, lack of hGH or crowding of cells can inhibit cell division.
Several proteins function as internal regulators to ensure each cell cycle stage is completed faithfully before proceeding to the next. Regulator molecules may act directly or influence the activity or production of other...

The Cell Cycle Control System01:28

The Cell Cycle Control System

3.8K
The cell cycle regulation directs how a cell proceeds from one phase to the next and begins mitosis. The cell cycle control system includes intracellular regulatory molecules and external triggers. They provide "stop" or "advance" signals and operate at specific cell cycle stages termed checkpoints to ensure that a particular process is completed before the cell advances to the next phase.
Cyclins and cyclin-dependent kinases (Cdks) are the primary cell cycle regulators and...

Role of Microtubules in Cell Wall Deposition01:02

Role of Microtubules in Cell Wall Deposition

2.6K
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and β-tubulin, two globular proteins. With a diameter of about 25 nm, microtubules are the widest components of the cytoskeleton. They help the cell resist compression and provide a track along which vesicles move through the cell or pull replicated chromosomes to opposite ends of a dividing cell. Microtubules go through quick cycles of...

Cell Adhesion in Plants01:14

Cell Adhesion in Plants

2.9K
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose,...

Summary
This summary is machine-generated.

SAMBA regulates plant cell division and growth by interacting with the anaphase-promoting complex/cyclosome (APC/C). Maize mutants reveal SAMBA’s conserved role in development, with dosage affecting growth rate.

Area of Science:

  • Plant molecular biology
  • Cell cycle regulation
  • Developmental genetics

Background:

  • SAMBA is a plant-specific regulator of the anaphase-promoting complex/cyclosome (APC/C).
  • APC/C controls cell cycle progression in plants.
  • SAMBA's role in monocots remained unstudied.

Purpose of the Study:

  • Investigate the conserved function of SAMBA in maize (Zea mays).
  • Characterize the developmental impact of SAMBA loss-of-function in maize.
  • Determine the relationship between SAMBA dosage and plant growth.

Main Methods:

  • Generated genome-edited maize mutants for SAMBA.
  • Phenotypic analysis of mutant growth, including internode length, leaf morphology, and cell division rates.
  • Biochemical analysis of SAMBA-APC/C interaction and activity.

Main Results:

  • SAMBA-APC/C association is conserved in maize.
  • Two samba mutants exhibited growth defects: reduced internode length, altered leaf architecture, and smaller leaf size.
  • Mutant phenotypes resulted from impaired cell division and expansion.
  • Differential mutant severity indicated a dosage-dependent role for SAMBA.
  • samba-3 mutation allowed partial function due to a truncated protein interacting with APC/C.

Conclusions:

  • SAMBA is essential for normal growth and development in maize, conserved from Arabidopsis.
  • SAMBA dosage influences developmental processes reliant on growth rate.
  • Understanding SAMBA’s role in APC/C regulation provides insights into plant development.
