“…Within the context of global climate change, warm winters and irregular occurrences of extreme weather have disrupted the timing of spring phenological events in tree species, increased the risk of frost damage, and caused abnormal fertility and poor fruit setting due to insufficient winter chill [ 9 – 12 ]. Therefore, it is important to study the flowering time control in perennial species and understand their adaptation mechanisms in synchronizing the timing of floral bud breaking and reproduction with local climate [ 10 , 13 , 14 ].…”

Background Phosphatidylethanolamine-binding proteins (PEBPs) constitute a common gene family found among animals, plants and microbes. Plant PEBP proteins play an important role in regulating flowering time, plant architecture as well as seed dormancy. Though PEBP family genes have been well studied in Arabidopsis and other model species, less is known about these genes in perennial trees. Results To understand the evolution of PEBP genes and their functional roles in flowering control, we identified 56 PEBP members belonging to three gene clades (MFT-like, FT-like, and TFL1-like) and five lineages (FT, BFT, CEN, TFL1, and MFT) across nine Rosaceae perennial species. Structural analysis revealed highly conserved gene structure and protein motifs among Rosaceae PEBP proteins. Codon usage analysis showed slightly biased codon usage across five gene lineages. With selection pressure analysis, we detected strong purifying selection constraining divergence within most lineages, while positive selection driving the divergence of FT-like and TFL1-like genes from the MFT-like gene clade. Spatial and temporal expression analyses revealed the essential role of FT in regulating floral bud breaking and blooming in P. mume. By employing a weighted gene co-expression network approach, we inferred a putative FT regulatory module required for dormancy release and blooming in P. mume. Conclusions We have characterized the PEBP family genes in nine Rosaceae species and examined their phylogeny, genomic syntenic relationship, duplication pattern, and expression profiles during flowering process. These results revealed the evolutionary history of PEBP genes and their functions in regulating floral bud development and blooming among Rosaceae tree species.

“…These epigenetic mechanisms serve as cellular memory, or an epigenetic clock modulating or silencing gene activation based on environmental cues. For example, exposure to low temperatures modulates expression of FLOWERING LOCUS C (FLC), in Cattani et al (2018). Prunus species have been used as models in the study of chilling requirements and bud dormancy since the expression profiles of DORMANCY-ASSOCIATED MADS-box (DAM) genes, which are tightly associated with dormancy stages, have been well characterized in the genus (Li et al, 2009;Zhebentyayeva et al, 2014).…”

“…Prunus species have been used as models in the study of chilling requirements and bud dormancy since the expression profiles of DORMANCY-ASSOCIATED MADS-box (DAM) genes, which are tightly associated with dormancy stages, have been well characterized in the genus (Li et al, 2009;Zhebentyayeva et al, 2014). Although these expression patterns are distinct to Prunus, they resemble mechanisms of FLC described in other species (Cattani et al, 2018). The genomic region around DAM6 has also been associated with differential levels of histone methylation (H3K4me3 and H3K27me3) and acetylation (H3ac) at distinct stages of dormancy in peach (Leida et al, 2012).…”

A review of plant epigenetics through the lens of almond

While genomes were originally seen as static entities that stably held and organized genetic information, recent advances in sequencing have uncovered the dynamic nature of the genome. New conceptualizations of the genome include complex relationships between the environment and gene expression that must be maintained, regulated, and sometimes even transmitted over generations. The discovery of epigenetic mechanisms has allowed researchers to understand how traits like phenology, plasticity, and fitness can be altered without changing the underlying deoxyribonucleic acid sequence. While many discoveries were first made in animal systems, plants provide a particularly complex set of epigenetic mechanisms due to unique aspects of their biology and interactions with human selective breeding and cultivation. In the plant kingdom, annual plants have received the most attention; however, perennial plants endure and respond to their environment and human management in distinct ways. Perennials include crops such as almond, for which epigenetic effects have long been linked to phenomena and even considered relevant for breeding. Recent discoveries have elucidated epigenetic phenomena that influence traits such as dormancy and self‐compatibility, as well as disorders like noninfectious bud failure, which are known to be triggered by the environment and influenced by inherent aspects of the plant. Thus, epigenetics represents fertile ground to further understand almond biology and production and optimize its breeding. Here, we provide our current understanding of epigenetic regulation in plants and use almond as an example of how advances in epigenetics research can be used to understand biological fitness and agricultural performance in crop plants.

“…Chilling temperatures can also inhibit abscisic acid (ABA) accumulation and induce the level of GA and FT to promote dormancy break in Populus (Rinne et al, 2011;Singh et al, 2018). In spite of the significant advances, the genetic network mediating floral bud break in perennial plants is far from complete (RÃos et al, 2014;Abbott et al, 2015;Fadón et al, 2015;Cattani et al, 2018).…”

Prunus mume is one of the most important woody perennials for edible and ornamental use. Despite a substantial variation in the flowering phenology among the P. mume germplasm resources, the genetic control for flowering time remains to be elucidated. In this study, we examined five blooming time-related traits of 235 P. mume landraces for 2 years. Based on the phenotypic data, we performed genome-wide association studies, which included a combination of marker- and gene-based association tests, and identified 1,445 candidate genes that are consistently linked with flowering time across multiple years. Furthermore, we assessed the global transcriptome change of floral buds from the two P. mume cultivars exhibiting contrasting bloom dates and detected 617 associated genes that were differentially expressed during the flowering process. By integrating a co-expression network analysis, we screened out 191 gene candidates of conserved transcriptional pattern during blooming across cultivars. Finally, we validated the temporal expression profiles of these candidates and highlighted their putative roles in regulating floral bud break and blooming time in P. mume. Our findings are important to expand the understanding of flowering time control in woody perennials and will boost the molecular breeding of novel varieties in P. mume.
