Summary: Salicylic acid (SA) delays fruit senescence by inhibiting ethylene (ET) biosynthesis. In this study, PpEIN3a gene was identified as a key regulator in fruit senescence and its expression was regulated by SA, ET, auxin, and glucose. SA plays an antagonistic role toward ET, auxin, and glucose in regulating the expression of PpEIN3a to delay fruit senescence.

Summary: The phytohormones ethylene and salicylic acid synergistically promote leaf senescence in Arabidopsis by interacting with transcription factors EIN3 and NPR1 to promote the expression of senescence-associated genes. The delayed senescence phenotype in the triple mutant indicates the importance of functional EIN3/EIL1 in NPR1-promoted leaf senescence.

Summary: Ethylene and jasmonate are plant hormones that regulate plant development and defense mechanisms. They act synergistically against fungal infections, but antagonistically in response to wounds and apical hook formation. The coordination of these responses is mediated by protein-protein interactions between EIN3/EIL1 and MYC transcription factors. These factors are both activated by interactions with MED25, which upregulates downstream gene expression. The study found that MED25's short binding domain is responsible for the interaction with EIN3/EIL1, suggesting competition between the two transcription factors for binding with MED25. This finding deepens our understanding of the coordination between the ethylene and jasmonate regulatory systems.

Summary: Phytopathogenic strains of Fusarium oxysporum cause destructive vascular wilt disease in economically important crops, and the use of resistant cultivars is an effective strategy for disease management. Our study showed that disruption of the BAM3 gene increased resistance to F. oxysporum f. sp. raphani, as the bam3 mutant exhibited reduced susceptibility to the pathogen. Additionally, cell wall pectin modification through methylesterification is important for bam3 defense responses against F. oxysporum.

Summary: Zingiber zerumbet, also known as 'Lempoyang', possesses various phytomedicinal properties, and its rhizome contains important secondary metabolites such as zerumbone and alpha-humulene. The synergistic effects of plant growth hormones and elicitors can enhance the production of zerumbone and alpha-humulene in adventitious root culture of Z. zerumbet.

Summary: Preharvest spraying of salicylic acid (SA, 1 mmol/L) at 72 and 74 days after complete bloom, combined with postharvest 1-methylcyclopropene (1-MCP, 1 mu L L-1) fumigation, effectively improves the storage quality of apricots. The combination of SA and 1-MCP treatment delays ethylene production, inhibits respiration, slows fruit softening, maintains high sugar and organic acid contents, and preserves high antioxidant capacity in apricots. The synergistic effects of SA + 1-MCP treatment enhance various parameters, while the antagonistic effects affect certain compounds and antioxidant capacity.

Summary: The tomato, known for its anti-oxidative and anti-cancer properties, is an important cash crop that brings various health benefits to humans. However, environmental stresses, particularly abiotic stresses, have a negative impact on tomato growth and productivity. This review examines how salinity stress affects tomato growth and development through toxicity by ethylene and cyanide, as well as ionic, oxidative, and osmotic stresses. The authors highlight the role of salicylic acid, compatible solutes, polyamines, and ethylene inhibitors in regulating ethylene and cyanide metabolism in response to salinity stress. They also discuss the cooperation between ethylene, salicylic acid, and polyamines with mitochondrial alternating oxidase, salt overly sensitive pathways, and the antioxidants system in enhancing salinity stress resistance in tomatoes.

Summary: Iron (Fe) and phosphorus (P) are essential elements for plant growth, but their availability in soil is limited. Ethylene and nitric oxide play important roles in activating genes related to Fe and P, and they work together with specific signals like Fe-peptides and microRNAs to confer specificity to the responses to each deficiency. This review aims to summarize the latest advances in the knowledge about Fe and P deficiency responses, considering the interactions among their main regulators and other related signals.

Summary: The study on Chinese rose plants revealed that light intensity can affect flowering time, and the phytochrome-interacting factors (PIFs) play an important role in this process. By interacting with the transcription factor CONSTANS (RcCO), the PIFs inhibit the expression of FLOWERING LOCUS T (RcFT), thereby affecting flowering time.
