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. Advances omics technologies have greatly facilitated identification gene resources, opening new opportunities genetic improvement. Importantly, several transcription factors participate responses, highlighting link between two processes. comprehensive elucidates complex mechanisms underlying regulation offering insights into biotechnological strategies production crops.

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(2), С. 769 - 769

Опубликована: Янв. 17, 2025

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.

A β‐ketoacyl carrier protein reductase confers heat tolerance via the regulation of fatty acid biosynthesis and stress signaling in rice

New Phytologist, Год журнала: 2021, Номер 232(2), С. 655 - 672

Summary Heat stress is a major environmental threat affecting crop growth and productivity. However, the molecular mechanisms associated with plant responses to heat are poorly understood. Here, we identified stress‐sensitive mutant, hts1 , in rice. HTS1 encodes thylakoid membrane‐localized β‐ketoacyl carrier protein reductase (KAR) involved de novo fatty acid biosynthesis. Phylogenetic bioinformatic analysis showed that probably originated from streptophyte algae evolutionarily conserved land plants. Thermostable predominantly expressed green tissues strongly induced by stress, but less responsive salinity, cold drought treatments. An amino substitution at A254T causes significant decrease KAR enzymatic activity and, consequently, impairs synthesis lipid metabolism especially under stress. Compared wild‐type, mutant exhibited heat‐induced higher H 2 O accumulation, larger Ca 2+ influx mesophyll cells, more damage membranes chloroplasts. Also, disrupted signaling depresses transcriptional activation of HsfA2s downstream target genes. We suggest critical for underpinning membrane stability, chloroplast integrity tolerance

Summary Tomato varieties resistant to the bacterial wilt pathogen Ralstonia solanacearum have ability restrict movement in plant. Inducible vascular cell wall reinforcements seem play a key role confining R. into xylem vasculature of tomato. However, type compounds involved such physico‐chemical barriers remain understudied, while being component resistance. Here we use combination histological and live‐imaging techniques, together with spectroscopy gene expression analysis understand nature ‐induced formation coatings We describe that tomato specifically responds infection by assembling structural barrier formed ligno‐suberin coating tyramine‐derived hydroxycinnamic acid amides. Further, show overexpressing genes pathway commercial susceptible variety restricts inside plant slows disease progression, enhancing resistance pathogen. propose induced plants does not only pathogen, but may also prevent degradation confer anti‐microbial properties, effectively contributing

Crop diseases cause enormous yield losses and threaten global food security. Deployment of resistant cultivars can effectively control the disease to minimize crop losses. However, high level genetic immunity was often accompanied by an undesired reduction in growth yield. Recently, literatures have been rapidly emerged understanding mechanism resistance development genes plants. To determine how why costs likely benefit caused varieties, we re-summarized present knowledge about crosstalk between plant those that function as plasma membrane residents, MAPK cassette, nuclear envelope (NE) channels components pleiotropic regulators. Considering growth-defense tradeoffs on basis current advances, finally, try understand suggest a reasonable balancing strategies based interplay with should be considered enhance capacity without penalty future breeding.

Drought stress is one of major environmental stresses affecting plant growth and yield. Although Pinus taeda trees are planted in rainy southern China, local drought sometime occurs can last several months, further their resin production. In this study, P. seedlings were treated with long-term (42 d), then targeted untargeted metabolomics analysis carried out to evaluate tolerance . Targeted showed that levels some sugars, phytohormones, amino acids significantly increased the roots needles water-stressed (WS) seedlings, compared well-watered (WW) pine seedlings.

Frontiers in Plant Science, Год журнала: 2023, Номер 14

Опубликована: Авг. 30, 2023

Root exudates comprise various primary and secondary metabolites that are responsive to plant stressors, including drought. As increasing drought episodes predicted with climate change, identifying shifts in the metabolome profile of drought-induced root exudation is necessary understand molecular interactions govern relationships between plants, microbiomes, environment, which will ultimately aid developing strategies for sustainable agriculture management. This study utilized an aeroponic system simulate progressive recovery while non-destructively collecting cotton (Gossypium hirsutum) exudates. The composition collected was characterized by untargeted metabolomics using Fourier-Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR MS) mapped Kyoto Encyclopedia Genes Genomes (KEGG) databases. Over 700 unique were identified throughout water-deficit phase. Potential KEGG pathways modules associated biosynthesis flavonoid compounds, hormones (abscisic acid jasmonic acid), other highly induced under severe drought, but not at wilting point. Additionally, precursors these metabolites, such as amino acids (phenylalanine tyrosine), phenylpropanoids, carotenoids, also mapped. potential biochemical transformations further calculated data generated FT-ICR MS. Under stress, highest number transformations, methylation, ethyl addition, oxidation/hydroxylation, identified, many known reactions some pathways. With application MS, we revealed dynamics response providing valuable information drought-tolerance cotton.
