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. In the context of the root meristem, CLE peptides act as critical regulators, influencing the size and activity of the stem cell niche.2025年8月6日—Antagonistic CLE peptide pathways shape root meristem tissue patterning. Nat. Plants Advance Access published October 28, 2024, doi:10.1038 ... This regulation is not a simple on/off switch but rather a complex balance. 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 developmentAntagonistic CLE peptide pathways shape root meristem tissue patterning. The activity of distinct and antagonistic CLE peptide pathways intersects to produce .... 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：H Zhang—Here, we review the intricate interplay between distinct andantagonistic CLEsignalingpathwaysin the primaryroot meristem, which suggests ....

Implications for Plant Development

The precise patterning of root meristem tissue is fundamental for a plant's ability to grow, anchor itself, and absorb water and nutrients. Disruptions in these antagonistic CLE peptide pathways can lead to significant developmental defectsControl of Arabidopsis shoot stem cell homeostasis by two .... 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. The continuous research into CLE peptide signaling pathways is vital for unraveling the complexities of plant development and harnessing this knowledge for future advancements.
