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. The WOX gene family is divided into three clades: ancient, intermediate, and modern (WUS) based on historical evolution linkage. The number of WOX genes in the plant body increases as plants grow more complex and varies in different species. Numerous research studies have discovered that the WOX gene family play a role in the whole plant's growth and development, such as in the stem, embryo, root, flower, and leaf. This review comprehensively analyzes roles of the WOX gene family across various plant species, highlighting the evolutionary significance and potential biotechnological applications in stress resistance and crop improvement.

Radish is an important annual root vegetable crop, whose yield is largely dependent on taproot thickening and development. However, the regulatory network of WOXs-mediated taproot development remains poorly understood in radish. Herein, the RsWOX13 was classified in an ancient clade of the WOX gene family that harbors a conserved homeodomain.

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.

Article Synopsis
- In rice, the transcription factor BABY BOOM 1 (OsBBM1) is crucial for activating the embryo development process right after fertilization, allowing for the formation of embryos without fertilization (parthenogenesis).
- Researchers found that another transcription factor, DWARF TILLER1 (OsDWT1/OsWOX9A), when expressed alongside OsBBM1 in egg cells, significantly boosts the chances of embryo formation—up to 91% parthenogenesis compared to just OsBBM1 alone.
- These findings highlight that the combined action of paternal genes is key to initiating embryo development, which can be applied to improve the production of haploid plants and hybrid seeds in agriculture.
