Phytopathogenic fungi are responsible for diseases in commercially important crops and cause major supply problems the global food chain. Plants were able to protect themselves from disease before humans played an active role protecting plants. They known synthesize a variety of secondary metabolites (SMs), such as terpenes, alkaloids, phenolic compounds, which can be extracted using conventional unconventional techniques formulate biofungicides; plant extracts have antifungal activity various mechanisms action against these organisms. In addition, they considered non-phytotoxic potentially effective control. sustainable economically viable alternative use agriculture, is why biofungicides increasingly recognized attractive option solve caused by synthetic fungicides. Currently, organic farming continues grow, highlighting importance developing environmentally friendly alternatives crop production. This review provides compilation literature on biosynthesis, phytopathogens, extraction formulation biofungicides, biological phytopathogenic fungi, regulation, advantages, disadvantages overview current agriculture.

The MdNAC72‐MdABI5 module acts as an interface integrating jasmonic acid and gibberellin signals and undergoes ubiquitination‐dependent degradation regulated by MdSINA2 in apple

New Phytologist, Год журнала: 2024, Номер 243(3), С. 997 - 1016

Опубликована: Июнь 7, 2024

Jasmonic acid (JA) and gibberellin (GA) coordinately regulate plant developmental programs environmental cue responses. However, the fine regulatory network of cross-interaction between JA GA remains largely elusive. In this study, we demonstrate that MdNAC72 together with MdABI5 positively regulates anthocyanin biosynthesis through an exquisite MdNAC72-MdABI5-MdbHLH3 transcriptional cascade in apple. interacts to promote activation on its target gene MdbHLH3 directly activates transcription MdABI5. The MdNAC72-MdABI5 module integration signals by combining repressor MdJAZ2 MdRGL2a. disrupts interaction attenuates MdNAC72. MdRGL2a sequesters from MdJAZ2-MdNAC72 protein complex, leading release E3 ubiquitin ligase MdSINA2 is responsive promotes ubiquitination-dependent degradation interface fine-regulates at posttranslational levels MdJAZ2, MdRGL2a, MdSINA2. summary, our findings elucidate connecting as core

Enhancing drought resistance in Dracocephalum moldavica L. through mycorrhizal fungal inoculation and melatonin foliar application

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Март 24, 2025

This research focused on improving the drought tolerance of Dracocephalum moldavica, a plant vulnerable to water stress, by exploring combined effects melatonin spray and mycorrhizal fungus Glomus intraradices inoculation. The experiment was designed as factorial randomized study evaluate plant's morphological, physiological, phytochemical responses under different conditions (100%, 75%, 50% field capacity). findings revealed that combination inoculation significantly improved morphological traits Moldavian balm conditions. Under severe (50% capacity), chlorophyll b levels increased 26.3% 35.5%, respectively, when both treatments were applied. Stress indicators, including electrolyte leakage malondialdehyde content, substantially reduced with simultaneous application symbiosis, indicating decreased cellular damage. Moreover, treatment resulted in highest activities antioxidant enzymes catalase peroxidase, suggesting these bolster oxidative stress defense mechanisms. Additionally, alone led an increase secondary metabolites like phenolic flavonoid compounds, which further amplified treatments. also observed significant alterations essential oil composition plant. Drought α-pinene, 1,8-cineole, borneol, increases even more pronounced Conversely, geraniol geranial treatment. Overall, this demonstrates can effectively enhance moldavica its physiological characteristics biochemical composition.

Multidimensional regulation of transcription factors: decoding the comprehensive signals of plant secondary metabolism

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Опубликована: Март 26, 2025

Plants synthesize an extensive array of secondary metabolites in response to diverse biotic and abiotic stresses. These function not only as defensive compounds but also constitute significant sources nutrition pharmaceuticals. However, the mechanisms governing synthesis these have long been a central focus research continue pose challenges. Transcription factors (TFs), serving key regulators metabolite plants, exhibit action that are still fully understood. This review summarizes latest advancements on how plant transcription mediate regulation biosynthesis through various signaling pathways, including light signaling, hormone MAPK ubiquitin-proteasome pathway, epigenetic regulation, microbial interactions, climate change. A deeper understanding regulating is expected provide new insights into metabolites.

The Good, the Bad, and the Epigenetic: Stress-Induced Metabolite Regulation and Transgenerational Effects

Epigenomes, Год журнала: 2025, Номер 9(2), С. 10 - 10

Опубликована: Март 29, 2025

Background: Plants face a wide range of environmental stresses that disrupt growth and productivity. To survive adapt, they undergo complex metabolic reprogramming by redirecting carbon nitrogen fluxes toward the biosynthesis protective secondary metabolites such as phenylpropanoids, flavonoids, lignin. Recent research has revealed these stress-induced processes are tightly regulated epigenetic mechanisms, including DNA methylation, histone modifications, chromatin remodeling, non-coding RNAs. Methods: This review synthesizes current findings from studies on both model crop plants, examining roles key regulators in controlling metabolism under stress. Special focus is placed dynamic changes acetylation, action small RNAs siRNAs miRNAs transcriptional post-transcriptional regulation. Results: Evidence indicates stress triggers rapid reversible modifications modulate gene expression linked to pathways. These not only facilitate immediate responses but can also contribute memory. In some cases, this memory retained transmitted next generation, influencing progeny responses. However, critical knowledge gaps remain, particularly concerning temporal dynamics, tissue specificity, long-term stability marks crops. Conclusions: Understanding how regulation governs metabolite production offers promising avenues enhance resilience productivity context climate change. Future should prioritize dissecting heritability support development epigenetically informed breeding strategies.
