Genome-Wide Identification and Functional Analysis of CLAVATA3/EMBRYO SURROUNDING REGION-RELATED (CLE) in Three Populus Species
2025
Overview
Intercellular communication mediated by CLAVATA3/EMBRYO SURROUNDING REGION-RELATED (CLE) peptides and their receptors is crucial for plant development and environmental adaptation. In this study, 45 and 89 CLEs were identified in Populus tomentosa and Populus alba × Populus glandulosa, respectively, and, together with the 52 CLEs in Populus trichocarpa, the chromosome localization, gene and protein characteristics, collinearity and gene duplication events, cis-acting regulatory elements in promoters and evolutionary relationships of CLEs in these three poplar species were analyzed. The CLEs of three poplar species were divided into four subfamilies. Among them, the CLEs in subfamilies I, II and IV were A-type CLEs, while those in subfamily III were B-type CLEs. During the evolutionary process of poplar, the selection pressure faced by whole-genome duplication or segmental duplication was purifying selection, and the duplication events led to the expansion of the CLE family in poplar. The exogenous addition of a certain concentration of poplar CLE13 peptides inhibits the root growth of Arabidopsis thaliana and poplar and simultaneously reduces the expression levels of ARFs and LBDs in the roots. In addition, drought stress induces the expression of PtrCLE13A. The overexpression of preCLE13A significantly enhances the osmotic and drought tolerance in Populus tomentosa. These results have provided valuable information for further research on the molecular mechanisms of CLE peptide signaling pathways in the woody model plant poplar regarding plant growth and stress resistance.
