“…Flowering is a key process which indicates the transition from vegetative to reproductive growth for plants, and genes of the PEBP family play important roles during this process and in the final plant architecture [ 3 ]. Up to now, the genes of the PEBP family have been identified in many plant species, such as quinoa, perilla, sugarcane, rice, garlic, etc., and the number of PEBP genes varies among these species [ 41 , 42 , 43 , 44 , 45 ]. A total of 13 PEBP family members were identified in M. integrifolia , and they were classified into three subfamilies: MFT-like , FT-like and TFL1-like .…”

Edible Macadamia is one of the most important commercial nut trees cultivated in many countries, but its large tree size and long juvenile period pose barriers to commercial cultivation. The short domestication period and well-annotated genome of Macadamia integrifolia create great opportunities to breed commercial varieties with superior traits. Recent studies have shown that members of the phosphatidylethanolamine binding protein (PEBP) family play pivotal roles in regulating plant architecture and flowering time in various plants. In this study, thirteen members of MiPEBP were identified in the genome of M. integrifolia, and they are highly similarity in both motif and gene structure. A phylogenetic analysis divided the MiPEBP genes into three subfamilies: MFT-like, FT-like and TFL1-like. We subsequently identified two TERMINAL FLOWER 1 homologues from the TFL1-like subfamily, MiTFL1 and MiTFL1-like, both of which were highly expressed in stems and vegetative shoots, while MiTFL1-like was highly expressed in young leaves and early flowers. A subcellular location analysis revealed that both MiTFL1 and MiTFL1-like are localized in the cytoplasm and nucleus. The ectopic expression of MiTFL1 can rescue the early-flowering and terminal-flower phenotypes in the tfl1–14 mutant of Arabidopsis thaliana, and it indicates the conserved functions in controlling the inflorescence architecture and flowering time. This study will provide insight into the isolation of PEBP family members and the key targets for breeding M. integrifolia with improved traits in plant architecture and flowering time.

“…Phosphatidylethanolamine-binding proteins (PEBPs) contain a conserved PEBP structural domain and exhibit a strong affinity for phosphatidylethanolamine [1]. They play an important role in regulating flowering, seed development, and germination in plants [1][2][3][4]. The PEBP gene family can be divided into three clades in angiosperms: MOTHER OF FT AND TFL1-like (MFT-like), FLOWERING LOCUS T-like (FT-like), and TERMINAL FLOWER-ING 1-like (TFL1-like) [5].…”

“…FT-like and TFL1-like genes are reported only in gymnosperms and angiosperms, whereas MFT-like genes can be traced back to the origin of land plants. Therefore, MFT-like genes are the common ancestor of FT-like and TFL1-like genes [4][5][6].…”

The PEBP gene family is involved in many biological processes in plants, including plant growth and development, flowering regulation, light response, and abiotic stress response. But there is little information about the role of the PEBP gene family in Cymbidium species. In this study, we identified 11, 9, and 7 PEBP genes in C. ensifolium, C. sinense, and C. goeringii, respectively, and mapped them to the chromosomes. We also studied the physicochemical characteristics of the proteins encoded by these PEBPs and analyzed their intra-species collinearity, gene structure, conserved motifs, and cis-acting elements. Furthermore, a total of forty PEBP genes from C. sinense, C. ensifolium, C. goeringii, Phalaenopsis, and Arabidopsis were divided into three clades based on the phylogenetic tree. The expression patterns of 11 PEBP genes in different tissues and organs of C. ensifolium were analyzed based on transcriptome data, indicating that the CePEBPs might play an important role in the growth and development, especially in the flower bud organs (1–5 mm). CePEBP5 plays an indispensable role in both the vegetative and reproductive growth cycles of C. ensifolium. CePEBP1 is essential for root development, while CePEBP1, CePEBP3, CePEBP5, and CePEBP10 regulate the growth and development of different floral organ tissues at various stages. The findings of this study can do a great deal to understand the roles of the PEBP gene family in Cymbidium.

Phosphatidylethanolamine binding protein (PEBP) plays an important role in regulating flowering time and morphogenesis of plants. However, the identification and functional analysis of PEBP gene in pineapple (AcPEBP) have not been systematically studied. The pineapple genome contained 11 PEBP family members, which were subsequently classified into three subfamilies (FT-like, TFL-like and MFT-like) based on phylogenetic relationships. The arrangement of these 11 shows an unequal pattern across the six chromosomes of pineapple the pineapple genome. The anticipated outcomes of the promoter cis-acting elements indicate that the PEBP gene is subject to regulation by diverse light signals and endogenous hormones such as ethylene. The findings from transcriptome examination and quantitative real-time polymerase chain reaction (qRT-PCR) indicate that FT-like members AcFT3 and AcFT4 display a heightened expression level, specifically within the floral structures. The expression of AcFT3 and AcFT4 increases sharply and remains at a high level after 4 days of ethylene induction, while the expression of AcFT7 and AcMFT1 decreases gradually during the flowering process. Additionally, AcFT3, AcFT4 and AcFT7 show specific expression in different floral organs of pineapple. These outcomes imply that members belonging to the FT-like subfamily may have a significant impact on the process of bud differentiation and flower development. Through transcriptional activation analysis, it was determined that AcFT4 possesses transcriptional activation capability and is situated in the nucleus and peripheral cytoplasm. Overexpression of AcFT4 in Arabidopsis resulted in the promotion of early flowering by 6-7 days. The protein interaction prediction network identified potential flower regulators, including CO, AP1, LFY and SOC1, that may interact with PEBP proteins. This study explores flower development in pineapple, thereby serving as a valuable reference for future research endeavors in this domain.
