Abstract
BACKGROUND Annexin (ANN) is calcium (Ca2+)-dependent and phospholipid binding protein family, which is involved in plant growth and development and response to various stresses. However, little known about ANN genes were identified from crape myrtle, an ornamental horticultural plant widely cultivated in the world. RESULTS Here, 9 LiANN genes were identified from Lagerstroemia indica, and their characterizations and functions were investigated in L. indica for the first time. The LiANN genes were divided into 2 subfamilies. The gene structure, chromosomal location, and collinearity relationship were also explored. In addition, the GO annotation analysis of these LiANNs indicated that they are enriched in molecular functions, cellular components, and biological processes. Moreover, transcription factors (TFs) prediction analysis revealed that bHLH, MYB, NAC, and other TFs can interact with the LiANN promoters. Interestingly, the LiANN2/4/6-9 were demonstrated to play critical roles in the branching architecture of crape myrtle. Furthermore, the LiANN2/6/8/9 were differentially expressed under salt treatment, and a series of TFs regulating LiANN2/6/8/9 expression were predicted to play essential roles in salt resistance. CONCLUSIONS These results shed light on profile and function of the LiANN gene family, and lay a foundation for further studies of the LiANN genes.

Wu K, Qu Y, Rong H, Han X, Tian Y, Xu L. Identification and Expression Analysis of the Populus trichocarpa GASA-Gene Family. Int J Mol Sci 2022; 23:ijms23031507. [PMID: 35163431 PMCID: PMC8835824 DOI: 10.3390/ijms23031507] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 01/22/2022] [Accepted: 01/22/2022] [Indexed: 02/04/2023] Open
Abstract
The gibberellic acid-stimulated Arabidopsis (GASA) gene family plays an important regulatory role in the growth and development of plants. In this study, we identified 19 GASA genes using bioinformatics-based methods in Populus trichocarpa, and these PtGASA genes could be divided into three categories based on their phylogenetic relationships. Based on an analysis of the structure and motifs of these genes, it was concluded that PtGASA class II members are more conserved than class I and class III members are, and the results of collinearity analysis showed that members of class II are collinearly related in poplar. Expression analysis of Populus trichocarpa roots, stems, and leaves showed that most of the PtGASA genes are expressed at higher levels in the stems or roots than in the leaves; a similar expression pattern was found in Vitis vinifera, indicating that the GASA-family members mainly play a role in the morphogenesis of poplar. Considering the phenomenon of gene amplification, we found that the higher the similarity of homologous genes was, the more similar the expression patterns. This study represents the first whole-genome identification and expression-profile analysis of the GASA-gene family in poplar, a model species, laying a foundation for functional studies of poplar GASA genes and serving as a reference for related research on other woody plant species.
