Plants have evolved complex mechanisms to cope with diverse abiotic stresses, the phenylpropanoid pathway playing a central role in stress adaptation. This produces an array of secondary metabolites, particularly polyphenols, which serve multiple functions plant growth, development, regulating cellular processes, and responses. Recent advances understanding molecular underlying metabolism revealed regulatory networks involving MYB transcription factors as master regulators their interactions signaling pathways. review summarizes our current polyphenol-mediated adaptations plants, emphasizing regulation function key compounds. We discussed how various including heat chilling stress, drought, salinity, light UV radiation, nanoparticles chemical heavy metal toxicity, modulate trigger accumulation specific polyphenolic The antioxidant properties these phenolic acids, flavonoids, anthocyanins, lignin, roles reactive oxygen species scavenging, neutralizing free radicals, membrane stabilization, osmotic adjustment are discussed. Understanding metabolic responses is crucial for developing stress-resilient crops improving agricultural productivity under increasingly challenging environmental conditions. provides comprehensive insights into integrating adaptation mechanisms, highlighting potential targets enhancing crop tolerance through adjustment.

Artemisia argyi is a traditional herbal medicine plant, and its folium artemisia widely in demand due to moxibustion applications globally. The Auxin/indole-3-acetic acid (Aux/IAA, or IAA) gene family has critical roles the primary auxin-response process, with extensive involvement plant development stresses, controlling various essential traits of plants. However, systematic investigation Aux/IAA A. remains limited. In this study, total 61 genes were comprehensively identified characterized. Gene structural analysis indicated that 46 proteins contain four typical domains, 15 belong non-canonical IAA proteins.

Auxin plays a crucial role in regulating root growth and development, its distribution pattern under environmental stimuli significantly influences plasticity. Under K deficiency, the interaction between K+ transporters auxin can modulate development. This study compared differences morphology physiological mechanisms of low-K-tolerant maize inbred line 90-21-3 K-sensitive D937 K-deficiency (K+ = 0.2 mM) with exogenous NAA (1-naphthaleneacetic acid, 0.01 treatment. Root systems exhibited higher absorption efficiency. Conversely, seedling roots demonstrated greater plasticity content. In-depth analysis through transcriptomics metabolomics revealed that showed differential responses to K-deficiency. In 90-21-3, upregulation expression transport-related proteins (proton-exporting ATPase potassium transporter) enrichment antioxidant-related functional genes were observed.

Plants frequently encounter relatively low and fluctuating potassium (K+) concentrations in soil, with roots serving as primary responders to this stress. Histone modifications, such de-/acetylation, can function epigenetic markers of stress-inducible genes. However, the signaling network between histone modifications low-K+ (LK) response pathways remains unclear. This study investigated regulatory role Deacetylase Complex 1 (HDC1) root growth Arabidopsis thaliana under K+ deficiency Using a hdc1-2 mutant line, we observed that HDC1 positively regulated LK conditions. Compared wild-type (WT) plants, exhibited significantly inhibited conditions, whereas HDC1-overexpression lines displayed opposite phenotypes. No significant differences were HK Further analysis revealed inhibition on was due reduced apical meristem cell proliferation rather than elongation. Notably, showed sensitivity compared WT after auxin treatment may regulate by affecting polar transport subsequent signaling, evidenced altered expression Moreover, organ-specific RT-qPCR analyses unraveled negatively regulates CBL-CIPK-K+ channel-related genes CBL1, CBL2, CBL3, AKT1, TPK1, thereby establishing molecular link deacetylation, CBLs-CIPKs pathway deficiency.
