“…The expression of the two genes increases as the flowers grow. This phenomenon indicates that these genes may be involved in the growth of G. biloba (Cheng et al, 2016;Wang et al, 2015). GbAGL66 is strongly expressed in the roots and flowers, with the highest level in the roots.…”

Flowering is an important stage in the life cycle of plants and also a turning point from vegetative growth to reproductive growth. This process is affected by many exogenous and endogenous factors. Some examples of the latter are endogenous hormones, plant growth status, nutrient composition, and flowering regulatory genes. Many gymnosperms have a long juvenile period. Previous studies attempted to shorten this period using traditional asexual propagation methods, but significant results have not been achieved. In recent years, molecular biology is used to study the flowering regulatory gene to obtain transgenic plants with early flowering trait. Thus, the production of gymnosperms is hastened, and economic efficiency is improved. Studies have shown that the flowering genes of plants act synergistically to form a complex network. In this paper, we reviewed the recent development in the study of the regulation of the flowering genes of gymnosperms, that is, from the floral meristem-specific gene, floral organ-specific gene, genes that inhibit plant flowering, and microRNA regulation of flowering. We provide a reference for the in-depth study on the genetic improvement of the flowering gene.

“…Although a small number of MADS-box genes have also been verified in Ginkgo [ 20 , 21 , 22 ], genome-wide identification and expression analysis from two genomes is still lacking. Studies have shown that genome duplication events often lead to an increase in gene family members and redundancy in function.…”

MADS-box transcription factors play important roles in many organisms. These transcription factors are involved in processes such as the formation of the flower organ structure and the seed development of plants. Ginkgo biloba has two genome versions (version 2019 and version 2021), and there is no analysis or comparison of the MADS-box gene family in these two genomes. In this study, 26 and 20 MADS-box genes were identified from the two genomes of Ginkgo, of which 12 pairs of genes reached more than 80% similarity. According to our phylogenetic analysis results, we divided these genes into type I (Mα and Mγ subfamilies) and type II (MIKC and Mδ subfamilies) members. We found that both sets of genomes lacked the Mβ gene, while the MIKC gene was the most numerous. Further analysis of the gene structure showed that the MIKC genes in the two genomes had extralong introns (≥20 kb); these introns had different splicing patterns, and their expression might be more abundant. The gene expression analysis proved that GbMADS genes were expressed to varying degrees in eight Ginkgo biological tissues. Type II GbMADS genes not only were found to be related to female flower bud differentiation and development but also are important in seed development. Therefore, MADS-box genes may play important roles in the development of Ginkgo reproductive organs, which may suggest a genetic role in sexual differentiation. This study further contributes to the research on MADS-box genes and provides new insights into sex determination in Ginkgo.
