The fig (the syconium of the Ficus tree) and its pollinating wasp represent exceptional examples for researching plant–insect interactions due to their remarkable specificity in species interaction mutually beneficial symbiotic relationship. However, mechanisms underlying developmental process monoecious figs response entry wasps (pollinators) metabolic changes occurring during this remain elusive. Our study employed a combination controlled experiments field LC-MS methods investigate impact on phase figs, as well alterations process. A total 381 metabolites 155 differential were identified, with predominant classes being organic acids, lipids, benzene aromatic compounds. results suggest that absence entry, receptive would exhibit an extended duration. upon wasps, terminate within span 1 2 days, concomitant substantial fluctuations composition proportions fig. research focuses analysis linoleic acid metabolism, phenylpropanoid biosynthesis, flavonoid biosynthesis pathways. findings triggers regulatory figs.

Abstract WRKY transcription factors (TFs) have evolved as a plant-specific gene family. Growing evidences indicate that TFs play crucial roles in plant growth, development, and responses to environmental stimuli. These primarily recognize W-box cis -elements less extent, WT-box. The binding affinity of these is modulated by protein folding, post-translational modifications, the nucleotide sequence adjacent core motif, including its methylation status. interaction proteins with receptors or components receptor complexes offers potential shortcut signaling pathway for prompt appropriate responses. Recent studies demonstrated can be targeted effectors from pathogens insects, leading shared events between distinct invaders. Modifications kinases other regulators alter their DNA-binding and/or transactivation abilities, thereby impacting expression target genes. Additionally, formation involving provides valuable insights into regulatory networks governed this TF This review highlights recent advancements understanding interactions -elements, well biotic abiotic stresses, metabolism, development.

Abstract Rice blast, caused by the filamentous fungus Magnaporthe oryzae (also known as Pyricularia ), is most severe disease threatening rice yield. Sakuranetin, an important plant phytoalexin, exhibits inhibitory effects on blast growth. However, underlying molecular mechanism which sakuranetin enhances resistance against pathogens remains unclear. A recent study published in Nature Communications Jiang et al. ( Nat. Commun , 2023, https://doi.org/10.1038/s41467-024-47746-y ) elucidated from a cytological perspective how to disease. The research revealed that elevated accumulation of attenuates endocytosis M. effectors into cytoplasm host cells. effect dosage-dependent and targets clathrin-mediated (CME). This provides novel insights understanding immune mechanisms weakening pathogen virulence weapons.
