Zanthoxylum bungeanum is one of the most important medicinal and edible homologous plants because its potential health benefits unique flavors. The chemical components in compositions contents vary with plant genotype variations various environmental stress conditions. Fatty acids participate metabolic pathways organisms to resist biotic abiotic stresses. To determine profiling genotypes, fatty acid key differential genes under low temperature two Z. varieties, cold-tolerant (FG) sensitive (FX), were investigated. Twelve main found varieties cold stress. Results showed that total unsaturated FG higher than those FX, which made more resistant temperature. Based on result orthogonal partial least squares discriminant analysis, palmitic acid, isostearic linolenic eicosenoic stress, while isomyristic stearic oleic FX. Furthermore, synthesis pathway acyl-ACP thioesterase A (FATA), Delta (8)-fatty-acid desaturase 2 (SLD2), protein ECERIFERUM 3 (CER3), (FAD3) 5 (FAD5) played roles FG, SLD2, FAD5, 3-oxoacyl-[acyl-carrier-protein] synthase I (KAS I), B (FATB) acetyl-CoA carboxylase (ACC) responding variation strategies revealed at molecular level.

ABSTRACT In their environment, plants are exposed to a multitude of abiotic and biotic stresses that differ in intensity, duration severity. As sessile organisms, they cannot escape these stresses, but instead have developed strategies overcome them or compensate for the consequences stress exposure.

To minimise metabolic constraints reduce costs defence, prioritise first‐line defence apoplastic space, involving ascorbate, defensins small peptides, as well secondary metabolites, before cellular processes affected. addition, large number symplastic also provide efficient including chemical antioxidants, antioxidative enzymes, other peptides proteins.

ABSTRACT Plant oils play a crucial role in human nutrition, industrial applications and biofuel production. While the enzymes involved fatty acid (FA) biosynthesis are well‐studied, regulatory networks governing these processes remain largely unexplored. This review explores intricate modulating seed oil biosynthesis, focusing on key pathways factors. Seed content is determined by efficiency of de novo FA synthesis as well influenced sugar transport, lipid metabolism, inhibitors fine‐tuning mechanisms. At center this network WRINKLED1 (WRI1), which plays conserved promoting across various plant species. WRI1 interacts with multiple proteins, its expression level regulated upstream regulators, including members LAFL network. Beyond network, we also discuss potential nuclear factor‐Y (NF‐Y) soybean an emphasis NF‐YA NF‐YB their associated proteins. NF‐Y represents promising avenue for future efforts aimed at enhancing accumulation improving stress tolerance soybean. Additionally, application omics‐based approaches great significance.

Alkaline environments such as alkaline lands, lakes, and industrial wastewater are not conducive to the growth of plants microorganisms due high pH salinity. ChbZIP1 is a bZIP family transcription factor isolated from an alkaliphilic microalgae (Chlorella sp. BLD). Previous studies have demonstrated its ability enhance tolerance in Arabidopsis thaliana. However, potential confer similar other remains unclear, specific mechanisms fully understood. The analysis cellular physiological biochemical indicators revealed that transformants exhibited enhanced photosynthetic activity, increased lipid accumulation, reduced fatty acid unsaturation. Genes associated with reactive oxygen species (ROS) detoxification were found be upregulated, corresponding increase antioxidant enzyme activity was detected. In addition, relative abundance intracellular ROS malondialdehyde (MDA) significantly lower transformants. summary, our research indicates enhances Chlamydomonas reinhardtii through several mechanisms, including repair damaged photosynthesis, improved unsaturation, activity. This study aims contribute more comprehensive understanding underlying alkalinity offers new insights theoretical foundations for utilization environments.
