Plant neighbor detection and allelochemical response are driven by root-secreted signaling chemicals
It is shown that the chemicals (-)-loliolide and jasmonic acid, which were present in the root exudates of a range of plant species, can be detected by wheat and induce allelochemical production. Expand
A broadleaf species enhances an autotoxic conifers growth through belowground chemical interactions.
The hypothesis that a broadleaf, non-N fixing species, Michelia macclurei, facilitates the performance of an autotoxic conifer Chinese fir (Cunninghamia lanceolata) through belowground chemical interactions is tested and it is concluded that interspecific interactions are less negative than intraspecific ones between non- N fixing broadleaf and autot toxic conifer species.

Allelobiosis in the interference of allelopathic wheat with weeds.
Through root-secreted chemical signals, allelopathic wheat can detect competing weeds and respond by increased allelochemical levels to inhibit them, providing an advantage for its own growth. Expand

The results suggest that the soil activity of allelochemicals on bioassay species and microbial communities depends on their mobility in soil. Expand
Allelochemical-mediated soil microbial community in long-term monospecific Chinese fir forest plantations
It is demonstrated that allelochemical cyclic dipeptide not only had direct phytotoxicity to tree roots but also indirectly altered soil microbial community compositions, suggesting that productivity decline of continuous Chinese fir monocultures may be a negative feedback interaction between alleLochemical-mediated soil microbialcommunity and root phytolipid fatty acid profiling.

The results showed that, during the vegetation change from evergreen broadleaved forest to Chinese fir plantation, the microbial biomass carbon and the quantities of culturable bacteria and actinomyces were decreased. Expand
Response of Water Resources to Future Climate Change in a High-Latitude River Basin
Global water resources are affected by climate change as never before. However, it is still unclear how water resources in high latitudes respond to climate change. In this study, the water resource… Expand
Precise dating of East-Asian-Monsoon D/O events during 95–56 ka BP: Based on stalagmite data from Shanbao Cave at Shennongjia, China
Based on 23 U/Th analyses and 532 oxygen isotopic data, an averaged 80-a stalagmite oxygen isotopic composition series was established through 95 to 56 thousand years before present (ka BP) from two… Expand
Susceptibility and tissue specificity of Spodoptera frugiperda to Junonia coenia densovirus
It is shown that Junonia coenia densovirus has great potential as a biological control agent against pests such as S. frugiperda or S. litura, and although JcDV can infect all three lepidopteran species, their susceptibility to the virus differs. Expand
