Summary: In apple, H3K4me3 plays a key role in establishing permissive chromatin states during bud dormancy and promoting bud break. In autumn, the high levels of H3K4me3 and the high expression of DAM genes are associated with bud dormancy. In winter, the lower levels of H3K4me3 and the lower expression of DAM genes and gibberellin metabolism genes control the release of dormancy. Warming conditions in spring increase H3K4me3 levels and facilitate the expression of genes related to phytohormones, the cell cycle, and cell wall modification, leading to bud break. Additionally, our study reveals that the activation of auxin and repression of ABA sensitivity in spring are partly regulated by temperature-mediated epigenetic regulation in winter.

Summary: This study explores the transcriptomic profiles of two apple cultivars, 'Honeycrisp' and 'Cripps Pink,' during endodormancy and ecodormancy. Through RNA-sequencing and PCA analysis, we observe that gene expression is specific to different time points and cultivars. Differentially expressed genes (DEGs) increase during endodormancy and remain elevated during ecodormancy, with only a few overlapping DEGs between time points. Co-expression network analysis reveals a significant gene module related to jasmonic acid biosynthesis, lipid metabolism, and transmembrane transport, suggesting their importance in apple bud dormancy and flowering.

Summary: Deciduous trees rely on stored non-structural carbohydrates for spring growth, with winter management of NSC playing a key role in priming trees for timely bloom. Defoliation and phloem girdling interrupt NSC accumulation and translocation, impacting spring phenology and delaying bud break in all three species studied.

Summary: This study found that starch levels generally declined and soluble sugars increased during dormancy in apple trees. H2O2 accumulation patterns showed correlations with dormancy stage and bloom dates. The redox balance was mainly maintained by catalase and to a lesser extent by glutathione during dormancy.

Summary: Apple rootstocks modify scions at the molecular level, affecting gene expression and hormone flux. Some Geneva apple rootstocks increase productivity in low chill environments by promoting the breaking of floral and vegetative buds in high chill scions like Gala and Fuji. The genotype of the rootstocks and the chilling treatment significantly impact the opening of apical and lateral buds, indicating a genetic effect of apple rootstocks on scion chilling requirement.

Summary: MdFLC-like gene in apple is associated with cold exposure and flower development, with its overexpression affecting plant growth rather than flowering in Arabidopsis. Seasonal expression patterns of MdFLC-like show earlier upregulation in 'Anna' compared to 'Fuji' and 'Tsugaru', potentially linked to genotype-dependent chilling requirements.

Summary: The activities of acid invertase and vacuolar invertase were investigated during bud dormancy release and bud break in deciduous fruit trees. Acid invertase activity increased sharply during bud break, indicating an increasing demand for carbohydrates. Vacuolar invertase activity showed a similar pattern but decreased after cold spells, potentially protecting the young leaf tissues from cold stress.

Summary: This study contributes to understanding acrotony in apple cultivars in a mild winter region, contrasting high- and low-chilling requirement apple cultivars, and the role of this behavior in plant adaptability. The research reveals that under mild winter conditions, apple trees do not enter deep endodormancy, and there are biological and biochemical differences between distal and proximal portions of bearing-shoots, likely due to higher sink force in the distal portion. Additionally, high chilling requirement cultivars in mild winter regions exhibit shallow endodormancy, emphasizing acrotonic branching.

Summary: The KNOX gene plays crucial roles in plant development, and this study identified 19 KNOX gene members in kiwifruit. One of the genes, AcKNOX11, is selectively expressed in flower buds and shoots, and its expression can be induced by ABA and melatonin. Functional analysis revealed that AcKNOX11 delays flowering, reduces plant height, alters leaf shape, and inhibits seed germination through ABA-melatonin interaction.

Summary: Bagging is a crucial cultivation measure that affects the quality of peach fruit by regulating exposure to light. This study investigated the effects of bagging on the content of phenolic compounds in peach fruit and identified the most sensitive compounds to bagging treatment. The study also explored the regulatory role of bagging on phenolic synthetic-related genes. The results showed that bagging affected the accumulation of different phenolics in different peach cultivars and light intensity played a significant role in the accumulation of anthocyanins and other phenolic substances in peach fruit. Additionally, the expression of structural genes and transcription factors related to phenolic synthesis was regulated by bagging and light conditions. These findings provide a foundation for understanding the regulation mechanism of light on the synthesis of phenolic compounds in peach fruit.

Summary: This study investigated the effects of water stress on cocoa trees and found that they are highly sensitive to water stress, with different genotypes exhibiting varied responses. Potassium application did not mitigate the negative effects of water stress. There was significant variation among genotypes in terms of leaf and crown traits, and positive interactions between genotype and irrigation were observed. These findings provide insights into the acclimation strategies of cocoa trees and can be useful for selecting drought-tolerant genotypes.
