The southwestern region of China is one of the last repositories of biodiversity. Exploring the genetic diversity and phylogeographical structure of representative species in this area can not only provide insights into their evolutionary history but also help us specify protection plans. We conducted extensive sampling and combined ISSR, cpDNA (A-H, F-H, L-F, D-I, G-S), and single-copy nuclear gene ( and ) data with the MaxEnt model to investigate the genetic diversity, phylogeographic pattern and potential distribution of Trattinnick, the "King of Vitamin C" fruit, in this region. The study revealed high genetic diversity within populations, with Guizhou Province identified as the center of origin. At least two glacial refugia were presented during the Quaternary ice age. The research emphasizes the impact of climate change and geographic isolation on genetic differentiation. This study contributes to the understanding of biodiversity in the southwestern region of China and offers a new perspective on the conservation of wild and other plant resources.
中国西南地区是生物多样性最后的储存库之一。探索该地区代表性物种的遗传多样性和系统地理结构，不仅可以深入了解它们的进化历史，还能帮助我们制定具体的保护计划。我们进行了广泛采样，并将ISSR、cpDNA（A-H、F-H、L-F、D-I、G-S）和单拷贝核基因（和）数据与最大熵模型相结合，以研究“维C之王”水果刺梨在该地区的遗传多样性、系统地理格局和潜在分布。研究揭示了刺梨种群内的高遗传多样性，确定贵州省为起源中心。第四纪冰期期间至少存在两个冰川避难所。该研究强调了气候变化和地理隔离对遗传分化的影响。这项研究有助于了解中国西南地区的生物多样性，并为野生刺梨和其他植物资源的保护提供了新的视角。
