Abstract
The filamentation temperature-sensitive H (FtsH) gene family, which is known to play a critical role in plant growth and development by regulating photosynthesis, chloroplast development, and response to plant stress, has been extensively studied in various species. However, the FtsH gene family in wheat has not been previously documented. In this study, 38 TaFtsH gene family members were identified, divided into eight groups and unevenly distributed across various chromosomes. Analysis of gene structure and conserved motifs revealed that TaFtsH genes within the same taxon share similar gene structures and conserved motifs. Further collinearity analysis provided insights into the evolutionary history of TaFtsH genes. Examination of cis-acting elements in the promoter region of TaFtsH genes revealed the presence of developmental and stress response elements in genes. The expression pattern of the wheat FtsH gene under various abiotic stresses was analyzed using real-time fluorescence quantitative PCR. Additionally, transient expression in tobacco verified the localization of the TaFtsH11-B protein in chloroplasts. These findings collectively contribute to laying the groundwork for the functional characterization of TaFtsH genes.
