“…This was supported by the fact that climatic characteristics shape population and regeneration of species (Hsiung et al, 2017). In addition, the relatively wide Bio4 indicated that the survival of F. wabuensis may be insensitive to temperature change, which aligned with Qin et al (2022), who indicated that alpine plants were more tolerant to environmental stresses. Meanwhile, low temperature seasonality was found to be consistent since most of the distribution areas of both…”

“…In addition, environmental factors serve as important aspect affecting the biological growth, reproduction as well as diversity (Roguz et al, 2021). For instance, the Fritillaria species, especially high-altitude species, are highly adapted to cold and dry climates, which may be a commercially important genetic pool (Qin et al, 2022). At present, wild Fritillaria resources have attracted much attention in light of their nut chemical composition and potential applications.…”

The Fritillaria species has become rare due to excessive harvesting, and thus identifying new ecological distribution of Fritillaria species and predicting its response to climate change are necessary for plant conservation and cultivation. In this study, areas with potential ecological suitability for Fritillaria delavayi, Fritillaria taipaiensis, and Fritillaria wabuensis were predicted using Biomod2 according to current occurrence records and bioclimatic variables. Temperature seasonality was the most important environmental variable for Fritillaria taipaiensis and Fritillaria wabuensis, while isothermality was most important for Fritillaria delavayi. The current suitable areas for three Fritillaria species were found to be distributed in south-west China, accounting for approximately 17.72%, 23.06% and 20.60% of the total area of China, respectively. During the highest concentration of greenhouse gas emission (SSP585), the suitable habitats of F. delavayi and F. wabuensis reached the maximum from 2021 to 2100, while that of F. taipaiensis reached the maximum from 2021 to 2100 during low emission (SSP126). The niche overlap of three Fritillaria species was found to be significantly related to the clustering tree based on chemical composition (P≤0.05), while no correlation was observed between niche overlap and DNA phylogenies, indicating that spatial distribution had a major influence on chemical composition in the Fritillaria species. Species-specific habitats were also predicted in order to decrease habitat competition. Overall, the findings of this study may offer new insight into the potential distribution and ecological niche of the three species for future conservation and management.

“…Phenylalanine metabolism is an important secondary metabolic pathway in plants that directly or indirectly produces a variety of phenyl propanoid metabolites including phytoalexin, lignin, flavonoids and hydroxycinnamic acid amides [ 30 ]. Phenyl propanoid metabolites are closely related to plant growth and development and also play a vital role in responses to biotic and abiotic stresses [ 31 ]. In this study, we found that Phenylalanine metabolism actively participated in drought resistance regulation in sugarcane at a molecular level.…”

Sugarcane (Saccharum spp. hybrid) is frequently affected by seasonal drought, which causes substantial declines in quality and yield. To understand the drought resistance mechanisms of S. officinarum, the main species of modern sugarcane, at a molecular level, we carried out a comparative analysis of transcriptome and metabolome profiling of the sugarcane variety Badila under drought stress (DS). Compared with control group (CG) plants, plants exposed to DS had 13,744 (6663 up-regulated and 7081 down-regulated) differentially expressed genes (DEGs). GO and KEGG analysis showed that the DEGs were enriched in photosynthesis-related pathways and most DEGs had down-regulated expression. Moreover, the chlorophyll content, photosynthesis (Photo), stomatal conductance (Cond), intercellular carbon dioxide concentration (Ci) and transpiration rate (Trmmol) were sharply decreased under DS. These results indicate that DS has a significant negative influence on photosynthesis in sugarcane. Metabolome analysis identified 166 (37 down-regulated and 129 up-regulated) significantly regulated metabolites (SRMs). Over 50% of SRMs were alkaloids, amino acids and their derivatives, and lipids. The five most significantly enriched KEGG pathways among SRMs were Aminoacyl-tRNA biosynthesis, 2-Oxocarboxylic acid metabolism, Biosynthesis of amino acids, Phenylalanine metabolism, and Arginine and proline metabolism (p < 0.05). Comparing CG with DS for transcriptome and metabolome profiling (T_CG/DS and M_CG/DS, respectively), we found three of the same KEGG-enriched pathways, namely Biosynthesis of amino acids, Phenylalanine metabolism and Arginine and proline metabolism. The potential importance of Phenylalanine metabolism and Arginine and proline metabolism was further analyzed for response to DS in sugarcane. Seven SRMs (five up-regulated and two down-regulated) and 60 DEGs (17 up-regulated and 43 down-regulated) were enriched in Phenylalanine metabolism under DS, of which novel.31261, Sspon.04G0008060-1A, Sspon.04G0008060-2B and Sspon.04G0008060-3C were significantly correlated with 7 SRMs. In Arginine and proline metabolism, eight SRMs (seven up-regulated and one down-regulated) and 63 DEGs (32 up-regulated and 31 down-regulated) were enriched, of which Sspon.01G0026110-1A (OAT) and Sspon.03G0002750-3D (P5CS) were strongly associated with proline (r > 0.99). These findings present the dynamic changes and possible molecular mechanisms of Phenylalanine metabolism as well as Arginine and proline metabolism under DS and provide a foundation for future research and sugarcane improvement.

“…Meanwhile, PAL, PTAL, C4H, 4CL, CCR, CAD, and PPOD are the key enzymes that catalyze the biosynthesis of lignin (Hura et al, 2023; Zhang et al, 2021). In addition, studies have shown that transcription factors such as MYB2 and MYB4 play a crucial role in lignin metabolism (Qin et al, 2022). In transgenic tobacco overexpressing MYB2 , MYB2 was found to act as a positive regulator and up‐regulate lignin metabolism by upregulating key genes such as CCR and CAD (Khan et al, 2019).…”

Drought is one of the leading environmental constraints that affect the growth and development of plants and, ultimately, their yield and quality. Foxtail millet (Setaria italica) is a natural stress‐resistant plant and an ideal model for studying plant drought resistance. In this study, two varieties of foxtail millet with different levels of drought resistance were used as the experimental material. The soil weighing method was used to simulate drought stress, and the differences in growth, photosynthetic physiology, metabolite metabolism, and gene transcriptional expression under drought stress were compared and analyzed. We aimed to determine the physiological and key metabolic regulation pathways of the drought‐tolerant millet in resistance to drought stress. The results showed that drought‐tolerant millet exhibited relatively stable growth and photosynthetic parameters under drought stress while maintaining a relatively stable level of photosynthetic pigments. The metabolomic, transcriptomic, and gene co‐expression network analysis confirmed that the key to adaptation to drought by millet was to enhance lignin metabolism, promote the metabolism of fatty acids to be transformed into cutin and wax, and improve ascorbic acid circulation. These findings provided new insights into the metabolic regulatory network of millet adaptation to drought stress.
