The Role of CLE Peptides in Root Meristem Development

CLE (CLV-like) peptides are a class of small signaling molecules that play pivotal roles in plant growth and development, particularly in meristems.Plant CLE peptides from two distinct functional classes ... In the context of the root meristem, CLE peptides act as critical regulators, influencing the size and activity of the stem cell niche. This regulation is not a simple on/off switch but rather a complex balance.New Article: "Antagonistic CLE peptide pathways shape ... Distinct CLE peptide signaling pathways can operate antagonistically, meaning one pathway might promote stem cell proliferation while another inhibits it, or they may influence different cell types or developmental processes within the meristem. This antagonistic interaction is key to achieving precise tissue patterning and maintaining the organized structure of the root tip, ensuring continuous root growth.

Mechanisms of Antagonistic Signaling

The concept of antagonistic CLE peptide pathways suggests that different CLE peptides, or the same peptides acting through different receptor complexes, can exert opposing effects on root meristem development. For instance, some CLE peptides might signal to maintain a pool of undifferentiated stem cells, while others might promote their differentiation into various cell lineages that form the root tissues. This balance is often mediated by receptor kinases, such as those in the CLAVATA1 (CLV1) family, and their co-receptors.作者：G Wang·2009·被引用次数：121—Is a CLV-like signalingpathwayinvolved inroot meristemmaintenance?

Disruptions in these antagonistic CLE peptide pathways can lead to significant developmental defects. For example, an imbalance could result in an enlarged or depleted stem cell pool, affecting overall root architecture and function. The study of these pathways not only deepens our understanding of plant biology but also holds potential for agricultural applications, such as improving crop root systems for better stress tolerance and nutrient uptake.Perception of root‐active CLE peptides requires CORYNE ...
