Cell Signaling in Plants

Cell Signaling in Plants

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...

Plant Hormones

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Meristems and Plant Growth

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.

Multipotency and Niche of Bulge Stem Cell

Multipotency and Niche of Bulge Stem Cell

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...

Morphogenesis

Morphogenesis

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.

Cells Coordinate Growth and Proliferation

Cells Coordinate Growth and Proliferation

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,...

Background:

Plant growth is regulated by complex hormonal pathways, transcriptional networks, and mechanical cues.
Brassinosteroids (BRs) are crucial plant hormones involved in various growth and developmental processes.

Purpose of the Study:

To review recent advances in brassinosteroid (BR) research.
To integrate BR signaling mechanisms into existing plant root growth models.
To elucidate the spatiotemporal roles and interactions of BRs in root development.

Main Methods:

Literature review of recent brassinosteroid (BR) studies.
Integration of BR signaling data with established root growth models.
Analysis of BR interactions with other hormones (e.g., auxin) and cellular components.

Main Results:

Brassinosteroid (BR) signaling exhibits spatiotemporal relevance in both longitudinal and radial root growth.
BRs interact intricately with auxin, influencing cell size determination.
BRs modulate the interplay between microtubules and the cell wall, affecting cell expansion.

Conclusions:

Brassinosteroid (BR) signaling is a key regulator of plant root architecture and cell size.
Understanding BRs' interaction with auxin and mechanical signals provides insights into growth control.
Emerging non-canonical BR signaling pathways may play roles in specific developmental contexts.
