Summary: The study demonstrates that MSI1 and HDA6 interact to repress flowering time control genes through histone modifications. HDA6-mediated H3K9 deacetylation is dependent on MSI1, while H3K27Me3 mediated by PRC2 containing MSI1 is also dependent on HDA6. The findings reveal the crucial role of the HDA6-MSI1 module in mediating the interaction between histone deacetylation and H3K27Me3 to repress gene expression.

Summary: This study evaluated the effects of ambient temperature changes on the expression of transgenerational plasticity in key developmental traits of Arabidopsis thaliana plants. The results showed that the environment during the whole life cycle of the first generation of plants influenced the germination response and flowering time of the second generation, while the production of reproductive biomass depended on the immediate environment of the progeny generation. Additionally, the seed area of the third generation was influenced positively by correlated environments across generations.

Summary: The timing of developmental transition can influence subsequent life stages. Habitat tracking through phenology can alter selection on postgermination traits. The results support the theoretical predictions of feedbacks between habitat tracking and traits expressed after habitat selection.

Summary: The timing of seasonal rains affects phenology and fitness of plant populations in Mediterranean climates. In this study, Arabidopsis thaliana was used to investigate the effects of rainfall onset on germination phenology and fitness. Results showed that germination timing was influenced by the timing of rainfall onset, and the fitness of the plants was affected by germination timing. High dormancy and early flowering genotypes had a fitness advantage in a Mediterranean climate.

Summary: Floral transition is regulated by multiple pathways, and the OR protein negatively regulates flowering by repressing the expression of key flowering genes, independent of vernalization or GA-dependent pathways.

Summary: In higher plants, floral signals are transmitted through FLOWERING LOCUS T (FT) and its orthologues, with the movement of FT being mediated by FT-INTERACTING PROTEIN1 (FTIP1). The study showed that NnFTIP1 mediates the transport of NnFT1 in Arabidopsis, indicating a conserved function between FTIP1 and FT in flowering plants. The interaction between NnFTIP1 and NnFT1, as well as the regulation of NnFTIP1 expression by NnUOF8, suggest a conserved mechanism in FT transport among different plant species.

Summary: This study investigated the remodeling of Arabidopsis seed phosphoproteome during imbibition using stable isotope dimethyl labeling and nanoLC-MS/MS analysis. The study identified a large repertoire of phosphopeptides and phosphoproteins involved in seed germination control, including protein kinases and key regulators like DOG1. Gene ontology analysis revealed their involvement in various biological processes. The study provides evidence of the major role of phosphosignaling in the regulation of Arabidopsis seed germination.

Summary: This review discusses recent advances in understanding the molecular and cellular mechanisms that generate variability in germination among genetically similar seeds. Plants have evolved a 'bet-hedging' strategy to survive in unpredictable environments, where high individual variation and a range of phenotypes are produced. While variability in seed behavior is beneficial for plant survival, it is not desirable in agriculture, where uniform seedlings are preferred. The review explores the hormonal, molecular, and cellular mechanisms that influence the germination outcome of genetically identical seeds.

Summary: Seed dormancy is a complex trait controlled by genetic and environmental factors, and it is affected by nitrate and AtAAH. Nitrate reduces seed dormancy, while AtAAH and other genes are up-regulated in dormant seeds. Ataah mutant seeds have higher dormancy and accumulate high levels of uric acid, allantoin, and urea.

Summary: The PavSVP gene plays a crucial role in regulating flowering and dormancy in sweet cherries, with its seasonal expression pattern associated with flower bud growth stages, causing delayed flowering and abnormal flower development. Moreover, PavSVP interacts with other genes, contributing to the regulation of the flowering process.

Summary: Selective pressures from herbicides have led to genetic changes in physiological traits of weeds, such as flowering time. The PfAGL28 gene isolated from herbicide-resistant weeds plays a crucial role in early flowering and pod formation. Overexpression of PfAGL28 in Arabidopsis thaliana resulted in early-flowering phenotype, providing insights into the flowering mechanisms of herbicide-resistant weeds.

Summary: Seed dormancy is a crucial developmental transition that affects plant adaptation and survival. In this study, it was found that the loss of function of two plant-specific histone deacetylases, HD2A and HD2B, enhanced seed dormancy in Arabidopsis. Silencing of HD2A and HD2B resulted in hyperacetylation of the DOG1 locus and increased DOG1 expression during seed maturation and imbibition. The study also revealed the interaction between HD2A, HD2B, HSI2, and HSL1. Overall, these findings suggest that HSI2 and HSL1 may recruit HD2A and HD2B to negatively regulate DOG1 expression and reduce seed dormancy, thus affecting seed development and germination.

Summary: Understanding how spaceflight affects plant flowering is crucial for long-term human space exploration. Recent space experiments showed that flowering initiation in plants was delayed by about 20 days in space compared to the control group on the ground, and gene expression levels were altered.

Summary: This study investigated the natural selection and genetic architecture of flowering time in Arabidopsis through field experiments in Europe. It found associations between loci related to flowering time and climate adaptation. The results showed selection for early flowering and increased stability, but little detection of plasticity. Genome-wide association studies identified significant associations with flowering traits and supported polygenic inheritance. The association of late flowering genotypes and alleles with climate presented evidence of past adaptation. However, current selection favored rapid flowering in agricultural settings.
