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.

Primary and Secondary Growth in Roots and Shoots03:02

Primary and Secondary Growth in Roots and Shoots

46.6K
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.

Cell Signaling in Plants01:25

Cell Signaling in Plants

4.4K
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...

Combinatorial Gene Control02:33

Combinatorial Gene Control

8.5K
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression.
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Regulation of Expression at Multiple Steps01:23

Regulation of Expression at Multiple Steps

1.3K
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...

Cells Coordinate Growth and Proliferation02:36

Cells Coordinate Growth and Proliferation

3.8K
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,...

Area of Science:

  • Plant biology
  • Developmental biology
  • Genetics

Background:

  • The stem cell niche paradigm is crucial for plant development.
  • The quiescent center regulates columella stem cell activity in Arabidopsis roots.

Purpose of the Study:

  • Investigate interactions between transcription factors regulating columella stem cells.
  • Quantify stem cell activity in the Arabidopsis root cap.

Main Methods:

  • Genetic analysis
  • Gene expression analysis
  • Quantitative method for stem cell activity

Main Results:

  • RETINOBLASTOMA-RELATED, FEZ, SOMBRERO, ARF10, ARF16, and WOX5 independently regulate columella stem cell number.
  • These factors act in a parallel manner.
  • WOX5 non-autonomously represses SOMBRERO activity.

Conclusions:

  • Columella stem cell development is quantitatively regulated by multiple broad-acting transcription factors.
  • This challenges the notion of a single intrinsic stem cell factor in plants.
