Summary: In this study, the molecular regulation of maize drought resistance was investigated through a genome-wide association study. It was found that the ZmSRO1d-R allele has a dual effect on drought resistance and grain yields. Interestingly, this allele was selected against during maize domestication and modern breeding, but its reintroduction into modern maize cultivars could contribute to food security under drought stress caused by global climate change.

Summary: The temporal variability of experimental drought mortality in conifers is best explained by an integrated trait that accounts for the rate at which the stomatal safety margin is crossed: the stomatal margin retention index. The regulation of water loss and the spread of xylem embolism have mostly been considered separately. The development of an integrated approach taking into account the temporal dynamics and relative contributions of these mechanisms to plant drought responses is urgently needed.

Summary: Xylella fastidiosa (Xf) is a bacterial pathogen that causes Pierce's Disease (PD) in grapevines and other diseases in important agricultural and ecological species. This study investigates the underlying mechanisms of Xf-induced mortality in grapevines and finds that susceptible genotypes show a coordinated decline in photosynthesis, starch storage, and stem hydraulics, while resistant genotypes do not show changes in starch and stem hydraulics. The results support the theory that hydraulic failure and carbon starvation are responsible for plant mortality resulting from PD.

Summary: Leaf stomata play a crucial role in the exchange of water vapor and carbon dioxide. Optimization models for stomatal regulation have been successful but differ in their mathematical details, indicating the need for further investigation. This study proposed a new stomatal optimization model based on water-carbon balance, and compared it with existing models. The results showed differences in stomatal sensitivity to soil moisture, and the new model captured the response patterns well.

Summary: Wheat response to water stress was evaluated in six genotypes, revealing different mechanisms of drought tolerance. Drought-sensitive genotypes exhibited accurate stomatal control to avoid turgor loss, leading to reduced yield. In contrast, drought-resistant genotypes developed solute accumulation and cell wall rigidity to enhance water uptake and protect against oxidative damages. Transcript analysis revealed distinct gene responses among genotypes, suggesting the regulation of drought tolerance in wheat involves the interaction between leaf water status and stomatal behavior. Syndiouk, D117, Utique, and Td7 were identified as potential candidates for breeding high-yielding and drought-tolerant wheat varieties.

Summary: This study aimed to investigate the effects of long-term nitrogen fertilization on non-structural carbohydrates (NSC) and nitrogen (N) status and their interaction in mature trees at the whole-tree scale. Nitrogen fertilization had varying effects on NSC and N concentrations in different tree organs, with increased NSC concentration in aboveground organs and decreased NSC concentration in fine roots. Nitrogen fertilization also increased N concentrations in all organs and had varied effects on total C concentrations.

Summary: This study investigated the impact of the 2018 European drought on beech trees and found that the hydraulic conductance of the trees was lost during the drought and did not recover in the following year. The decline in hydraulic function was associated with defoliation symptoms and a decrease in wood starch concentration. The findings suggest that leaf development after drought acclimates to mitigate disturbances in canopy hydraulic function.

Summary: Tree crowns experience strong vertical microclimatic gradients, particularly in light availability. Little is known about whether these gradients cause within-crown variation in leaf phenology and whether such variations represent different light-use strategies of sun-and shade leaves. We measured the annual leaf phenology in the upper and lower crowns of mature trees from different species and found that microclimatic canopy gradients are strongest during summer and may drive phenological gradients in autumn.

Summary: This perspective article addresses the recent interest in treeline studies as a result of attempts to identify climate warming effects on mountain and arctic vegetation. The article emphasizes the importance of clear-cut definitions, consistent terminology, and a theoretical framework for hypothesis testing. By applying the ecological niche concept, the potential and realized niche edges can be used to define the climatic limit and deviations of tree growth at treeline. Additionally, it is explained why other abiotic factors, such as microclimate and moisture, do not diminish the classical isotherm concept.

Summary: This study aimed to investigate if apple and pear trees grafted on dwarfing and invigorating rootstocks differ in the size and dynamics of non-structural carbohydrate (NSC) storage pools. The results showed that, despite some differences in NSC concentrations between low and high vigor trees, the size of the NSC pools scaled tightly with the overall tree biomass. Therefore, these results do not support the idea that differences in growth vigor are driven by the availability of C-reserves.

Summary: In a 2013 paper, Lenz et al. investigated the effects of chronic warming or cooling on trees growing at the low-temperature limit. They found that a 3 K cooling did not impact lignification at treeline, but when a frost event occurred during early ring formation, the cooling resulted in a non-lignified layer of cells followed by normally lignified cells. This suggests that chronic cooling does not affect lignification but increases the risk of frost damage in premature xylem tissue.

Summary: The use of size-controlling rootstocks is essential for high-density fruit production systems. Water relations and carbohydrate storage ability may play important roles in controlling growth vigor. Our study on apple trees grafted on two rootstocks with different growth vigor revealed that dwarfed trees had smaller trunk radial increments due to an earlier cessation of trunk secondary growth. Dwarfed trees also showed less interdiurnal trunk circumference changes and fewer days with positive changes during dry summer months. These trees exhibited lower turgidity in the cambial region, resulting in limited trunk radial expansion. Additionally, dwarfed trees maintained lower leaf water potential and leaf gas exchange rates during the summer drought. The concentrations and seasonal dynamics of non-structural carbohydrates were similar in both rootstock combinations, indicating that NSC reserves were not directly limiting growth. Overall, our results highlight the importance of water relations in rootstock-induced size control mechanisms and emphasize the complexity of this topic.

Summary: This study investigates the factors controlling stomatal uptake of atmospheric gaseous elemental mercury (Hg(0)) by tree foliage, using foliage samples from across Europe. The study finds that the functional group of trees and the nutrient content of the leaves significantly impact foliar stomatal Hg uptake, while water vapor pressure deficit and soil water content also play a role in regulating Hg uptake. These findings suggest the need to consider tree physiological activity and stomatal response in models of Hg cycling in the future.

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: 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.
