Special Issue Information

Dear Colleagues,

Metabolic responses of plants to biotic/abiotic stress are crucial for their survival and adaptation in various environmental conditions. Environmental conditions include drought, salinity, heat stress, heavy metal pollution, nutrient deficiency, and multiple organisms like microorganisms and animals. When faced with such pressures, the plants mobilize their defense mechanisms, such as metabolism, to safeguard their well-being. Special regulatory factors, including exogenous or endogenous factors, play a key role in initiating these defense responses. For example, regulatory factors modulate metabolic biosynthesis or gene expression related to osmoprotectants accumulation (e.g., proline), antioxidant enzymes production (e.g., superoxide dismutase), and stomatal closure regulation (e.g., ABA-responsive genes). These adaptations help plants maintain cellular homeostasis and minimize damage caused by abiotic/biotic stresses. The exogenous or endogenous factors include chemical substances, including inorganic or organic, rhizospheric/endophyte microorganisms and others.

Understanding the intricate interplay between metabolic responses and regulatory factors is essential for developing strategies to enhance plant resilience against various stresses. This Special Issue of Metabolites is devoted to original research and review articles on the effect of exogenous or endogenous regulatory factors on the metabolic responses of plants to biotic/abiotic stress. Topics of interest to this Special Issue include, but are not limited to, the following:

  • Induction of metabolite biosynthesis in plants subjected to biotic/abiotic stresses that are regulated by exogenous or endogenous regulatory factors;
  • Root exudates under biotic and abiotic;
  • Plant metabolite biosynthesis under biotic/abiotic;
  • Lipid metabolism of plants under biotic/abiotic and the mechanism characterization;
  • Exogenous chemical substances that enhance plant stress tolerance and their mechanism characterization;
  • Environmental microorganisms, including endophytes, enhance plant stress tolerance and facilitate mechanism characterization;
  • Induction of metabolite biosynthesis in plants via regulated factors in response to biotic and abiotic stresses.

Light quality and sucrose-induced osmotic stress are known to cause anthocyanin synthesis in detached Lycium ruthenicum leaves. To identify the mechanisms by which the kind of light quality and sucrose concentration are induced, here, we conducted transcriptome sequencing in detached L. ruthenicum leaves treated with different qualities of light and sucrose concentrations. Leaves treated with blue light or sucrose showed a significantly increased total anthocyanins content compared to those treated with white light. Delphinidin-3-O-rutinoside and delphinidin-3-O-glucoside production were differentially regulated by the BL(−S), BL(+S), and WL(+S) treatments. The structural genes CHS, CHI, F3′H, F3′5′H, ANS, and UFGT were significantly up-regulated in leaves treated with blue light or sucrose. Leaves treated with blue light additionally showed up-regulation of the light photoreceptors CRY1, PIF3, COP1, and HY5. The anthocyanin-related genes NCED1, PYR/PYL, PP2C, SnRK2, and ABI5 were significantly up-regulated in leaves treated with sucrose, promoting adaptability to sucrose osmotic stress. Co-expression and cis-regulatory analyses suggested that HY5 and ABI5 could regulate LrMYB44 and LrMYB48 through binding to the G-box element and ABRE element, respectively, inducing anthocyanin synthesis in response to blue light or sucrose treatment. Candidate genes responsive to blue light or sucrose osmotic stress in the anthocyanin biosynthesis pathway were validated through quantitative reverse transcription PCR. These findings deepen our understanding of the mechanisms by which blue light and sucrose-induced osmotic stress regulate anthocyanin synthesis, providing valuable target genes for the future improvement in anthocyanin production in L. ruthenicum.
