Cadmium (Cd) pollution poses a growing threat to plant growth. Although glutathione (GSH) is recognized for its potential mitigate Cd-induced stress, specific effects on alleviating such stress in Pogostemon cablin (patchouli) remain unclear. This study investigated physiological parameters and enzymatic activities across four treatment groups: control (CK), cadmium (Cd), (GSH), with (GSH+Cd). Results revealed that chlorophyll a, b, carotenoid levels the GSH were approximately 20 % higher than those other groups. In contrast, antioxidant enzyme activity Cd decreased by about 15 %. Integrated transcriptomic metabolomic analyses demonstrated mitigates influencing glycerophospholipid metabolism flavonoid biosynthesis, key roles attributed dgkA1, dgkA2, CCoAOMT1-4. conclusion, alleviates P. enhancing photosynthetic pigment synthesis, reducing reactive oxygen species (ROS) through improved activity, regulating metabolic pathways. These findings provide valuable insights optimizing cultivation management of under conditions.

WRKY Transcription Factors in Response to Metal Stress in Plants: A Review

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(20), P. 10952 - 10952

Heavy metals in soil can inflict direct damage on plants growing within it, adversely affecting their growth height, root development, leaf area, and other physiological traits. To counteract the toxic impacts of heavy plant mitigate metal stress through mechanisms such as chelation, vacuolar compartmentalization, regulation transporters, enhancement antioxidant functions. WRKY transcription factors (TFs) play a crucial role development well responses to both biotic abiotic stresses; notably, is classified an stressor. An increasing number studies have highlighted significant proteins regulating across various levels. Upon entry ions into cells, production reactive oxygen species (ROS) triggered, leading phosphorylation activation TFs MAPK cascade signaling. Activated then modulate processes by upregulating or downregulating expression downstream genes confer tolerance plants. This review provides overview research advancements regarding ion stress—including cadmium (Cd), arsenic (As), copper (Cu)—and aluminum (Al) toxicity.
