Summary: This experiment explored the signal transmission mechanism of the arbuscular mycorrhizal network against root rot in Salvia miltiorrhiza. It was found that jasmonic acid plays an important role in signal transmission and can transmit the resistance signal to root rot by inhibiting salicylic acid. The arbuscular mycorrhizal network is also significant for the disease resistance and stress resistance of Salvia miltiorrhiza.

Summary: This study investigates the molecular mechanism of salicylic acid (SA), jasmonic acid (JA), and abscisic acid (ABA) in watermelon resistance against Fusarium wilt. The up-regulated expression of certain genes is found to be critical in defense against the pathogen. Additionally, there may be crosstalk between SA, JA, and ABA in triggering the plant immune system.

Summary: The study investigated the floral induction process in Chenopodium ficifolium and found that high levels of stress-related phytohormones and the expression of oxidative stress genes were increased under long photoperiods. However, this did not affect plant growth and flowering. The stimulation of cytokinin and gibberellic acid signaling pathways under short days may indicate their involvement in floral initiation, while the accumulation of auxin metabolites suggests the presence of a regulatory network.

Summary: This study investigated the relationship between hormone levels, gene expression, and chilling injury in pepper fruit. 'TK' genotype was less sensitive to low temperature, while 'GG' genotype showed higher sensitivity, and GABA and CaARF19 were possibly associated with chilling injury levels.

Summary: This study reveals that overexpression of MtCBL13 in Arabidopsis increases sensitivity to drought stress. Transgenic plants overexpressing MtCBL13 exhibit enhanced sensitivity to mannitol and ABA treatments during seed germination and seedling stages. Furthermore, overexpression of MtCBL13 reduces drought tolerance in Arabidopsis, leading to increased oxidative damage, electrolyte leakage, lipid peroxidation, and water loss. These findings demonstrate that MtCBL13 negatively regulates drought tolerance through an ABA-dependent pathway.

Summary: Plants encounter various microorganisms at the root-soil interface, which can have harmful or beneficial effects. By studying a tripartite interaction between Medicago truncatula, Sinorhizobium meliloti, and Fusarium oxysporum, researchers found that the high expression of certain genes induced by symbiotic bacteria interfered with the establishment and functioning of symbiosis. Additionally, the down-regulation of a common signaling pathway gene was observed, along with a decrease in symbiosis parameters and an accumulation of certain compounds.

Summary: Continuous light or predominant nitrogen supply as ammonium can induce leaf chlorosis and inhibit plant growth. Strong stress from CL and exclusive NH4+ supply synergistically inhibit growth, while mild stress enhances accumulation of stress hormones like jasmonic acid and ACC. This modulation of hormonal composition plays a potential role in plant growth responses to combined CL and NH4+ application.

Summary: Phytophthora capsici is a destructive pathogen causing quick wilt disease in black pepper, and metabolomic analysis revealed shifts in amino acid, tricarboxylic acid cycle, nucleotide and vitamin B6 metabolism upon infection. Jasmonate and salicylate application reduced disease symptoms, but the effects were suppressed with abscisic acid, indicating the reprogramming of phytohormone defenses in infected leaves and a potential approach for disease control.

Summary: This review analyzes the role of plant hormones in Colletotrichum infections, revealing that different strains of Colletotrichum are capable of auxin production, which may contribute to their virulence. The authors propose auxin biosynthetic pathways in Colletotrichum spp. in the context of plant-Colletotrichum interactions.

Summary: This study investigated the effect of clubroot, a soilborne disease caused by Plasmodiophora brassicae, on plant hormones in Brassica napus. The results showed that the pathogen modulated plant hormonal networks, leading to increased levels of SA and ABA in susceptible plants, and decreased levels of JA. This modulation of plant hormones could be important for understanding plant defense mechanisms against clubroot.

Summary: The study found that unlike Aldrovanda, Utricularia does not use jasmonates for the activation of carnivorous response, making it the second genus in Lamiales that has not co-opted jasmonate signaling for botanical carnivory. Both genera secrete digestive fluid containing cysteine protease homologous to dionain, but the regulation may vary between them.

Summary: Plant hormones play a crucial role in regulating plant interactions with their environment. Hormone crosstalk, involving synergistic, antagonistic, and additive interactions, is essential for tailoring plant responses to diverse microbes and insects. Recent advances have shed light on the mechanisms of hormone crosstalk regulation in plant defense.

Summary: The study found that the sensitivity to short-term acute UV-B doses in different varieties of quinoa is influenced by their parental lines and breeding time; UV-B sensitivity does not necessarily correlate with quinoa's geographical distribution; the role of flavonoids in the UV-B response seems to be different depending on varieties; moreover, changes in JA and SA correlate with UV-B tolerance, while the increase of ABA is mainly related to UV-B stress.

Summary: This study aimed to investigate the interaction between Xanthomonas campestris pv. campestris (Xcc) and the plant hormone abscisic acid (ABA) in stomatal movement. The results showed that Xcc infection induced the expression of several immune-related genes and accumulation of phytohormones, leading to stomatal closure. Exogenous ABA application, on the other hand, induced stomatal closure through different mechanisms. These findings are important for understanding the molecular mechanisms underlying the interaction between plants and pathogenic bacteria.

Summary: Plant viruses can cause plant diseases, with the severity and spread of symptoms potentially impacted by climate change; elevated CO2 levels can reduce virus disease severity in some plants, possibly enhancing plant defense mechanisms; studies suggest that reduced disease occurrence under enhanced CO2 levels may be the norm.

Summary: This study investigated the elicitors in insect oral secretions from seven lepidopteran insects with varying associations with maize plants. New pests were found to have higher total contents of FACs in their oral secretions, leading to increased maize emissions. Variations in FACs may be due to differences in internal FAC degradation and fatty acid excretion.

Summary: Trichoderma species are widely used biocontrol agents with antagonistic properties against various plant pathogens. Chlamydospores, produced by many fungi, have thick walls and high resistance to adverse conditions. Chlamydospores of Trichoderma spp. have better application potential and longer shelf life, but large-scale production remains difficult. By conducting a comprehensive analysis of transcriptome dynamics during chlamydospore formation, important pathways and genes involved in each stage were identified.

Summary: Apoptosis and autophagy are two common forms of programmed cell death used by host organisms to fight against virus infection. In this study, researchers found that the coat protein (CP) of an insect-borne plant virus TYLCV interacts with a phosphatidylethanolamine-binding protein (PEBP) in its vector whitefly, leading to the activation of apoptosis and autophagy in the whitefly, affecting viral load. The results suggest that the viral load is predominantly determined by autophagy rather than apoptosis.

Summary: Apoptosis and autophagy are two important processes for host intracellular immunity against virus infection. A study on tomato yellow leaf curl virus (TYLCV) infected whiteflies revealed that the virus hijacks a master regulator called PEBP4 to activate apoptosis and autophagy simultaneously. The viral coat protein (CP) captures membrane-localized PEBP4, stabilizing its association with RAF1. This triple complex blocks a MAPK phosphorylation cascade and triggers apoptosis. At the same time, the CP competes for PEBP4 binding, promoting the disassociation of PEBP4 from ATG8 and initiating autophagy. Apoptosis increases the viral load, while autophagy degrades the virus. Only a balanced immune response involving both apoptosis and autophagy allows long-term coexistence between vectors and arboviruses.
