To systematically elucidate the adaptation mechanism of Zenia insignis to karst drought habitats and to provide theoretical support for the rational development and utilization of its resources as well as ecological restoration of rocky desertification, this paper systematically reviews research findings on Z. insignis at home and abroad. It summarizes research progress from the perspectives of provenance reproductive characteristics, morphological anatomy and physiological drought resistance mechanisms, rhizosphere symbiotic microbial interaction, community site adaptation characteristics, molecular biology, and resource utilization. Existing studies have confirmed that Z. insignis can adapt to karst drought stress through multiple pathways, including specialized root architecture, physiological osmotic regulation, antioxidant system modulation, and synergistic symbiosis with arbuscular mycorrhizal fungi. However, there remain issues such as fragmented research on adaptation mechanisms, insufficient exploration of indigenous microbial resources, an imperfect multi-trait breeding system for superior varieties, and a lack of mixed afforestation models. In the future, it is necessary to rely on multi-omics joint analysis and in-situ field controlled experiments to systematically elucidate the multi-dimensional synergistic drought resistance mechanisms of Zenia insignis, screen indigenous microbial strains and superior provenances adapted to karst habitats, and establish a scientific and large-scale ecological restoration afforestation system for rocky desertification. All these efforts will promote the coordinated development of ecological governance and forestry carbon sink industry in the karst region of northwestern Guangxi. |
