Summary: A study found that adding sunflower oil and a commercially-available antitranspirant DPM to plants had similar effects in reducing water loss, and the rate of water loss decreased as the concentration of sunflower oil increased. If other plant oils are equally or more effective in reducing water loss, they could be used as low-cost antitranspirants in large-scale commodity crops and by smallholder farmers in low-income countries.

Summary: The study showed that both film antitranspirants and metabolic antitranspirants can increase grain yield under drought conditions, with a more pronounced effect observed in controlled drought scenarios. Leaf ABA concentration was negatively correlated with yield, but multiple applications of exogenous ABA could lead to higher yields.

Summary: This study investigated the impact of water availability and nitrogen fertilization on plant growth, nutrient dynamics, and soybean crop yield. The results showed that water deficiency and absence of nitrogen fertilization decreased the accumulation and partitioning of various nutrients in plants. Although nitrogen fertilization led to increased nitrogen accumulation in tissues, it did not enhance yield significantly, while the highest seed yields were observed in plants under full irrigation regardless of nitrogen supplementation. However, deficient irrigation reduced the seed oil content in nitrogen-fertilized plants. In conclusion, nitrogen fertilization is crucial for nutrient homeostasis, and water availability affects biomass and nutrient accumulation, thus limiting soybean yield performance.

Summary: This study showed that all genotypes of L. alba were negatively affected by drought stress in terms of physiological processes, whereas the qualitative profile of volatile organic compounds was mainly determined by genotype rather than drought stress. Gas exchange and chlorophyll a fluorescence were identified as the most sensitive parameters for evaluating drought stress in L. alba specimens.

Summary: Enhancing drought tolerance in rice varieties is crucial for addressing global food demand. Significant progress has been made in understanding the mechanisms involved in adaptation and tolerance to drought stress in rice over the past two decades. Breeding drought tolerant rice varieties remains a challenging task due to the complex nature and multigenic control of drought tolerant traits.

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.

The use of NB up to 2% alleviated salinity and drought stress and increased yield, while decreasing salinity and irrigation water depth increased water productivity. The appropriate use of NB can reduce the negative effects of stress and promote the sustainable production of quinoa.

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.
