WUSCHEL-related homeobox (WOX) proteins are very important in controlling plant development and stress responses. However, the WOX family members and their role in response to abiotic stresses are largely unknown in melon ( L.). In this study, 11 WOX (CmWOX) transcript factors with conserved WUS and homeobox motif were identified and characterized, and subdivided into modern clade, ancient clade and intermediate clade based on bioinformatic and phylogenetic analysis. Evolutionary analysis revealed that the CmWOX family showed protein variations in Arabidopsis, tomato, cucumber, melon and rice. Alignment of protein sequences uncovered that all CmWOXs had the typical homeodomain, which consisted of conserved amino acids. -element analysis showed that genes may response to abiotic stress. RNA-seq and qRT-PCR results further revealed that the expression of partially genes are associated with cold and drought. and were constitutively expressed under abiotic stresses, may play a role in abiotic processes during plant development. Taken together, this study offers new perspectives on the CmWOX family's interaction and provides the framework for research on the molecular functions of genes.

Article Synopsis
- CLAVATA3/EMBRYO SURROUNDING REGION (CLE) peptides are crucial for positional signaling in plants, working with receptor-like kinases and WOX transcription factors to maintain stem cell functions.
- Recent research identified 11 CLE-encoding genes in the Ceratopteris genome, with CrCLV3 being similar to the well-studied CLAVATA3, and functional studies revealed its role in promoting cell proliferation and stem cell identity in ferns.
- Additionally, CrCLV3 regulates the WOX gene CrWOXA during key developmental stages, enhancing our understanding of CLE peptide functions and the evolutionary relationship between CLE and WOX signaling in land plants.

The adaptation of plants to land requires sophisticated biological processes and signaling. Transcription factors (TFs) regulate several cellular and metabolic activities, as well as signaling pathways in plants during stress and growth and development. The WUSCHEL-RELATED HOMEOBOX (WOX) genes are TFs that are part of the homeodomain (HD) family, which is important for the maintenance of apical meristem, stem cell niche, and other cellular processes.

Article Synopsis
- - The root system is vital for plant growth as it absorbs nutrients and water, with stem cells in the roots being crucial for their development.
- - WOX5 is a key regulator of root stem cell fate in Arabidopsis, but its stability and modulation were previously unknown.
- - The study shows that the peptidase DA1 interacts with and cleaves WOX5, affecting its stability, and that cytokinin signaling increases DA1 levels, linking it to root stem cell function.

Article Synopsis
- Scientists used a tool called CRISPR to change a gene in tomato plants called SlWOX4 to help them survive better in dry conditions.
- The SlWOX4 gene usually makes plants lose water quickly and doesn't help with their reaction to drought.
- By knocking out the SlWOX4 gene, the tomato plants showed improved ability to stay healthy in drought, including less water loss and stronger defenses against damage.
