Summary: This study examines the changes in flowering synchrony within and among plant communities in response to changing climate. The results show that flowering synchrony significantly decreases with increasing temperatures and has locally-dependent effects in combination with reduced precipitation. However, there is an increase in synchrony within plant species occurring in multiple communities, indicating a homogenization of flowering phenology across the gradient. These changes in flowering synchrony may have far-reaching and negative effects on ecosystem stability.

Summary: This study examines the changes in flowering phenology of pear trees, finding that flowering has advanced by 11.44 days in the past 30 years. This advancement is evident in all pear tree cultivars and phenological stages, and is likely to continue in future climate scenarios. The earlier flowering could lead to mismatches between plants and pollinators, changes in agricultural spraying regimes, increased risk of frost exposure, and exacerbated impacts of pest populations.

Summary: This study aimed to investigate the mating systems and pollination success of alpine plants. The results showed that most alpine plants have a common mating system of outcrossing, and the fruit-set success varied seasonally in response to pollinator activity. Bumble bees are the main pollinators for alpine plants, and the success of pollination differed among different pollinator types. The flowering phenology of alpine plants is regulated by snowmelt patterns, and the pollination success also varied among local populations in different snowmelt habitats.

Summary: This study used ensemble modeling to estimate the changes in apple flowering and fruit-setting, and found that apple phenology stages occurred earlier and the sensitive windows shortened. Although this phenomenon reduced frost frequency in some regions, the increase in frost intensity could offset this alleviation and increase frost risks in other regions. In addition, the climatic risks of poor pollination were lower than late-spring frost risks except for a few regions. The model ensemble provides a realistic assessment for quantifying future risks of late spring frost and poor pollination in apple production systems.

Summary: Alpine plants exhibit different strategies based on their latitude, with tropical alpine plants having multiple flowering peaks throughout the year, while temperate and subtropical alpine plants synchronize their flowering within a short period. The diversity in flowering phenology increases the resilience of alpine plants to climate change, but also exposes some species to higher vulnerability.

Summary: This study investigated the allocation to growth, reproduction, and defence in maritime pine under different resource availability and simulated herbivory treatments. The results showed that fertilization increased tree growth and seed quantity but not seed quality. Needle clipping and methyl-jasmonate treatment increased needle resin and phenol concentrations. Overall, there were complex interactions among the life-history dimensions, suggesting that pairwise approaches are insufficient to unravel these complexities.

Summary: The xanthophyll cycle plays a significant role in protecting plants from membrane peroxidation induced by intense light exposure. This study identified 240 differentially expressed genes associated with respiratory chain, lipid metabolism, antioxidant activity, and flavonoid metabolism. The overexpression of the CmBCH1 gene resulted in the upregulation of genes involved in scavenging reactive oxygen species and encoding antioxidants, leading to the accumulation of xanthophyll, zeaxanthin, chlorophylls, and anthocyanins. The study highlighted the potential of BCH1 in regulating the xanthophyll cycle and enhancing tolerance to intense light stress in transgenic plants.

Summary: This study demonstrated that co-expressing two exogenous genes, tfdB and bphC, in Arabidopsis thaliana improved the tolerance and removal efficiency of PCB28. Transgenic plants also exhibited increased enzymatic activities under PCB28 stress. The co-expression of tfdB and bphC in A. thaliana resulted in nearly twofold increase in PCB28 removal rates from soil. This research suggests that co-expressing two genes holds great potential for enhancing phytoremediation efficiency and mitigating PCB-induced toxicity stress on plants.

Summary: Trichomes are specialized plant structures that protect plants and are regulated by complex gene networks and signaling pathways. Gene expression, cell cycle regulation, and differentiation determine whether cells become trichomes. Transcription factors, epigenetic modifications, and phytohormones play important roles in trichome development. The integration of phytohormonal and transcriptional networks contributes to the diversity and adaptability of trichomes in plants.

Summary: The impact of multifactorial abiotic stress combinations on plant functional responses remains controversial. The halophyte Salicornia ramosissima showed unique functional responses depending on the specific stress factors involved. Under extreme conditions, there was a more negative impact on plant functional traits, but the presence of beneficial microorganisms, especially in combination with elevated atmospheric CO2 concentration, mitigated these negative effects.

Summary: In eukaryotic cells, epigenetic modifications of DNA and histones play a crucial role in gene expression regulation. ROXY19, a plant-specific CC-type glutaredoxin, was found to strongly repress a subset of genes regulated by class II TGA factors through its association with the TPL/TPR family. The ectopic expression of ROXY19 in Arabidopsis plants led to hypersensitivity to xenobiotic chemicals due to the silencing of detoxification pathway genes.

Summary: This study identified and characterized 163 C2H2-type zinc finger proteins in non-heading Chinese cabbage. Two of these proteins, BcZAT12 and BcZAT10, were found to be closely related to cold tolerance and acted as transcriptional repressors in regulating cold resistance. Furthermore, BcZAT12 was shown to directly bind to the promoter of BcCBF1 and inhibit its activity. Additionally, interactions between BcZAT12 and other proteins such as BcABF2/4 were observed. These findings provide insights into the functional roles and regulatory mechanisms of C2H2-ZFPs in non-heading Chinese cabbage under cold stress.

Summary: Soil salinization is a major obstacle for agriculture sustainability, as it severely affects plant growth and crop yield. Ethylene, a stress hormone, plays a crucial role as a signal molecule in coordinating plant growth and stress response in the model plant Arabidopsis. However, the roles and mechanisms of ethylene in most crop plants under salinity remain undefined. This review summarizes the universal roles of ethylene and focuses on its divergent roles in rice and other crop species under salinity, particularly in terms of ethylene biosynthesis and signal transduction. The contradictions between ethylene production and signaling in salt response are also discussed.
