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: The study reveals that the Arabidopsis floral repressor gene FLC is co-transcriptionally repressed by COOLAIR, with the involvement of AGO1 in promoting COOLAIR splicing dynamics and chromatin silencing. AGO1 is shown to associate with COOLAIR and influence its processing, leading to the resolution of R-loops and local chromatin environment conducive to low transcription initiation. These findings suggest a conserved cotranscriptional regulation mechanism involving AGO1 that influences transcriptional output.

Summary: In this study, the effects of jasmonate and salicylate on the susceptibility of tomato plants to necrotrophic fungus R. solani were observed. It was found that salicylate priming provided better tolerance than jasmonate priming. Microscopic and molecular techniques revealed the defense mechanisms of salicylate and jasmonate during infection.

Summary: This study analyzes the changes in gene expression in WBPH-resistant rice plants overexpressing the OsF3H gene compared to wild type plants after WBPH infection. The results show significant differences in gene expression between the two genotypes, with many DEGs related to oxidoreductase activity, stress response, hormone regulation, and defense response to pathogens. The overexpression of OsF3H also leads to changes in plant hormones and pathogenic-related and secondary-metabolites-related genes, enhancing the plant's resistance to WBPH infestation.

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: Cotton is an important crop for textile fiber production, but it is threatened by parasitic nematodes such as Meloidogyne incognita. This study explores the molecular mechanisms of resistance to M. incognita in cotton and finds that the constitutive activation of defense-related genes and phytohormone responses, specifically jasmonic and salicylic acid, in the roots of resistant cotton cultivars contribute to RKN resistance. The findings suggest promising candidate genes for introducing RKN resistance into commercial cotton varieties.

Summary: Prior exposure to microbial-associated molecular patterns or specific chemical compounds can induce stronger defence responses in plants. In this study, the researchers investigated the molecular processes involved in beta-aminobutyric acid (BABA)-induced resistance (BABA-IR) in tomato. They found that BABA restricts the growth of certain pathogens and acts mainly as a stress factor in tomato, activating signaling and perception machinery. The study also revealed key differences between BABA effects on tomato and other model plants.

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: Through the study of the cat2 mutant in Arabidopsis, which lacks the major leaf isoform of catalase, we are able to investigate the potential impact of intracellular H2O2 on plant function. Our analysis focused on the salicylic acid and jasmonic acid pathways reveals metabolic signatures associated with oxidative stress-induced signaling via these defense hormones. We also identify specific enzymes and genes involved in the glucosylation of SA and the production of dihydroxybenzoic acid glycosides.

Summary: This research elucidates the transcriptional control mechanism of the master clock protein CCA1 on the downstream target gene GRP7, and its impact on pathogen defense. The study demonstrates that CCA1 physically associates with the promoter of GRP7 and regulates its circadian expression, leading to altered defense signaling and pathogen responses.

Summary: The Ilyonectria radicicola species complex contains soilborne necrotrophic plant pathogens, with I. mors-panacis being the most aggressive to ginseng roots. Infected roots show severe root rot, while leaves and stems also exhibit symptoms. Aggressive Ilyonectria species suppress host defense mechanisms, allowing for extensive colonization. Genetic approaches are needed to further understand the host-pathogen interactions.

Researchers used the CRISPR/Cas9 system to modify tomato genes, resulting in increased resistance against bacterial and fungal pathogens. This study contributes to improving crop breeding for enhanced biotic stress resistance.

Summary: The hormones salicylic acid (SA) and jasmonic acid (JA) have opposing roles in plant defense against different pathogens. Threonine deaminase (TD) plays a role in JA responses by producing the Ile needed for the bioactive JA-Ile conjugate. This study shows that TD2 has a negative effect on defense against hemibiotrophic pathogens and a positive effect on defense against necrotrophic pathogens.

Summary: Genome editing is widely used in various plant species to study functional mutations for crop improvement, however, concerns about transgene integration in plant genomes have sparked legislative debates. Various strategies have been developed to prevent gene editor constructs from integrating, including genetic segregation, transient editor expression, and DNA-independent editor delivery methods. This review discusses the advantages and disadvantages of these different tools and aims to provide important information on alternative genome editing strategies for crop breeding.

Summary: The study established a GLABRA2 mutation-based GBVS system to enrich nonchimeric mutants in Arabidopsis T1 plants. Compared to the original system, GBVS enhanced mutation screening efficiency and allowed for quicker and more efficient obtainment of homozygous or biallelic monogenic mutants and nonchimeric polygenic mutants in Arabidopsis.
