“…Phenylpropanoid, flavonoid, and isoflavonoid can eliminate free radicals in plants and enhance their antioxidant capacity to reduce oxidative damage caused by high calcium environment (Li et al, 2018). Moreover, some flavonoids, such as anthocyanins, can enhance the color of plant leaves and maintain a high photosynthetic capacity of plants, which is an important adaptive mechanism for golden Camellia to adapt to the high-calcium environment (Liu et al, 2022a). Firstly, in isoflavonoid biosynthesis, eight genes were found to be upregulated and related to CYP81E, which is an important metabolic enzyme in various isoflavones' synthesis in roots of Cpu, Cpe, Cgr, and Cli compared with Ctu.…”

“…Certain types of golden Camellia growing in karst regions exhibit some adaptive features to their karst environment. In our previous study, golden Camellia from different growth areas (Camellia nitidissima from acidic soil and Camellia limonia from karst soil) were treated with high calcium to analyze the adaptation mechanism of golden Camellia in karst environment according to their differences in morphology and physiology, and it was found that golden Camellia growing in the karst soil has a more stable photosynthetic capacity and water retention ability (Liu et al, 2022a). Various studies have recently demonstrated that golden Camellia was capable of adapting to drought stress in karst areas by changing the size of its stomata and by developing leathery leaves (Chai et al, 2021;Zhu et al, 2021;Zhu et al, 2022b), but the specific adaptation mechanism in transcription level is still unclear.…”

Camellia sect. Chrysantha is an important rare and protected plant species. Some golden Camellia species grow in karst soil while others grow in acidic soil. In order to study the adaptation mechanism of golden Camellia to the karst environment, four species of golden Camellia growing in the karst soil (Camellia pubipetala, Camellia perpetua, Camellia grandis, and Camellia limonia) and four species growing in the acidic soil (Camellia nitidissima, Camellia euphlebia, Camellia tunghinensis, and Camellia parvipetala) were selected for this study. Combining the metagenome and transcriptome, the structure and function of the rhizosphere microbial communities and the gene expression in roots of golden Camellia were analyzed. The results showed that the rhizosphere microbial communities in different golden Camellia were significantly different in abundance of Acidobacteria, Actinobacteria, Candidatus_Rokubacteria, Nitrospirae, Planctomycetes, and Candidatus_Tectomicrobia. The proportion of Candidatus_Rokubacteria was significantly higher in the rhizosphere soil of four species of golden Camellia grown in karst areas, compared to C. nitidissima, C. euphlebia, and C. tunghinensis. The linear discriminant analysis Effect Size showed that C. parvipetala was similar to karst species in the enrichment of ABC transporters and quorum sensing. During the transcriptome analysis, numerous upregulated genes in four karst species, including CYP81E, CHS, F3H, C12RT1, NAS, and CAD, were found to be enriched in the secondary metabolite synthesis pathway in the KEGG library, when compared to C. tunghinensis. This study provides information for plant adaptation mechanisms on the rhizosphere soil microbial composition and gene expression in secondary metabolic pathways to karst habitats and its distribution in karst areas.

“…A recent cultivation trial showed that CSC also grows normally in low-Ca environments, while ASC is less well adapted to high-Ca environments [4]. The adaptation of these plants to environments with different Ca ion concentrations may be related to significant variations in photosynthetic and physiological indices, such as their contents of chlorophyll, proline, soluble sugars, or flavonoids [4,5]. However, our knowledge of the mechanisms by which golden Camellia species adapt to different soil habitats, especially in the field, is still poor.…”

Contrasting Adaptation Mechanisms of Golden Camellia Species to Different Soil Habitats Revealed by Nutrient Characteristics

Golden Camellia species are highly specific to certain soil environments. Most species are only native to calcareous soils in karst regions, except for a few that grow only in acidic soils. Our aim is to elucidate the adaptation mechanisms of the species of calcareous-soil golden Camellia (CSC) and acidic-soil golden Camellia (ASC) to habitat soils through plant–soil nutrient characteristics and their relationships. We investigated 30 indices for soils and plants. Compared with ASC, CSC had more fertile soil, while their plant tissues exhibited stronger Ca, P, and Mn and weaker K storage, which may be important mechanisms for adapting to habitat soils. However, ASC showed a higher biological absorption coefficient (BAC) for nutrients, which may contribute to the adaptation of ASC to relatively barren acidic soils. Both CSC and ASC showed much higher BAC and accumulation of Ca than other nutrients. We also found that the concentrations of nutrients in the different tissues varied considerably between species. Correlation analysis revealed 135 significant relationships between the 30 indices, with the soil pH and soil Ca levels being the most important factors influencing the nutrient uptake network. This information helps in understanding the adaptation mechanisms of karst plants to habitat soils.
