“…Ionizing radiation also inhibited Predatory or Exoparasitic , thus indirectly stabilizing ecosystem productivity ( Liu et al, 2022 ), which, in turn, affects soil nutrient changes ( Ning et al, 2021 ). In addition, the Δ 13 C value reflects the water use efficiency of plants ( Song and Liu, 2020 ), and the Δ 13 C values of the low and medium groups are significantly lower than that of the blank group, but the Δ 13 C value of the high group do not differ significantly from that of the blank group, indicating that the symbiotic microbial effect can restore the water use efficiency of plants damaged by radiation. In summary, we believe that root symbiotic microorganisms are important research objects to regulating the function of plant–microorganism–soil systems under LLR and coping with global ionizing radiation pollution in future.…”

As the environmental nuclear radiation pollution caused by nuclear-contaminated water discharge and other factors intensifies, more plant–microorganism–soil systems will be under long-term low-dose ionizing radiation (LLR). However, the regulatory mechanisms of the plant–microorganism–soil system under LLR are still unclear. In this study, we study a system that has been stably exposed to low-dose ionizing radiation for 10 years and investigate the response of the plant–microorganism–soil system to LLR based on the decay of the absorbed dose rate with distance. The results show that LLR affects the carbon and nitrogen migration process between plant–microorganism–soil through the “symbiotic microbial effect.” The increase in the intensity of ionizing radiation led to a significant increase in the relative abundance of symbiotic fungi, such as Ectomycorrhizal fungi and Rhizobiales, which is accompanied by a significant increase in soil lignin peroxidase (LiP) activity, the C/N ratio, and C%. Meanwhile, enhanced radiation intensity causes adaptive changes in the plant functional traits. This study demonstrates that the “symbiotic microbial effect” of plant–microorganism–soil systems is an important process in terrestrial ecosystems in response to LLR.

“…A. catalpifolium is endangered, but because genomic information was previously unavailable, conservation efforts for this tree have been limited to traditional methods such as natural interventions ( Song and Liu 2020 ). In this study, we generated a high-quality genome of A. catalpifolium , thus accelerating future research and aiding in conservation of this tree.…”

“…Scientists have carried out many studies on A. catalpifolium to understand this population decline. The possible negative effects of decreased seed germination, shade from neighboring dominant species, and severe human disturbance on A. catalpifolium growth and biomass accumulation have been researched ( Zhang et al 2019 ; Song and Liu 2020 ). Moreover, population structure analysis shows that A. catalpifolium has a tendency to convert from a stable population to a decline-type population ( Zhang et al 2018 ; Xu and Liu 2019 ).…”

Acer catalpifolium is an endangered species restricted to remote localities of West China. Understanding the genomic content and evolution of A. catalpifolium is essential to conservation efforts of this rare and ecologically valuable plant. Here, we report a high-quality genome of A. catalpifolium consisting of ∼654 Mbps and ∼35,132 protein-coding genes. We detected 969 positively-selected genes in two Acer genomes compared with four other eudicots, 65 of which were transcription factors. We hypothesize that these positively-selected mutations in transcription factors might affect their function and thus contribute to A. catalpifolium’s decline-type population. We also identified 179 significantly expanded gene families compared to 12 other eudicots, some of which are involved in stress responses, such as the FRS-FRF family. We inferred that A. catalpifolium has experienced gene family expansions to cope with environmental stress in its evolutionary history. Finally, 109 candidate genes encoding key enzymes in the lignin biosynthesis pathway were identified in A. catalpifolium; of particular note were the large range and high copy number of cinnamyl alcohol dehydrogenase genes. The chromosome-level genome of A. catalpifolium presented here may serve as a fundamental genomic resource for better understanding endangered Acer species, informing future conservation efforts.

The effect of radioactivity on the environment, especially on plants, has always been one of the vital researches of radio-ecology. However, long-term irradiated ecosystems are very rare. Occasionally, one special miniature ecological environment object consisted of thorium mineral (Th-232) and Tradescantia flumnensis L. over 10 years is carried out to evaluate the effect of long-term low-radioactivity gamma radiation on herbaceous plant. Several functional features of Tradescantia flumnensis L. are selected and measured with physical measurement (PM), HPGe portable gamma-ray spectrometer (HPGe PGS), wavelength dispersion X-ray fluorescence (WDXRF), and advantage isotope ratio mass spectrometer (AIR-MS). The results show that functional traits varied with the increasing of radiation dose rate. These results also indicate that the plants can adapt to low-intensity gamma radiation (<332.6 nGy•h-1) through adjustment of physical properties. In addition, low-intensity gamma radiation has positive influence on plant's water use efficiency, growth and nutrition acquisition of roots. Restrictions on plant phosphorus demand have also been eased. However, high-intensity gamma radiation (>528.7 nGy•h-1) has exceeded the tolerance of plants, making most functional traits unhealthy or abnormal. This rare case is of great reference significance of setting biological indicators of long-term radiation system.
