In the context of plant conservation and sustainable use of unique neglected and underutilized phytogenetic resources, this study focused on the Tunisian local endemic Teucrium luteum subsp. gabesianum (Lamiaceae). Using Geographical Information Systems and online databases, detailed taxon-specific ecological profiling was produced for the first time, which illustrated the temperature and climate conditions in its wild habitats and facilitated the investigation of how temperature affects its seed germination, thus making its cultivation in anthropogenic environments possible. Following the seed propagation first reported herein (77.5−81.25% at temperatures between 15 and 25 °C), species-specific in situ and ex situ conservation efforts or sustainable exploitation strategies can be enabled. This study also reported for the first time how chemical and integrated nutrient management (INM) fertilizers affect the growth and pilot cultivation of its seedlings (INM more advantageous). The firstly-reported herein DNA barcoding may enable its traceability, allowing future product design. The multidisciplinary approach followed has paved the way to bridge important research gaps hindering conservation efforts and/or the sustainable exploitation of this local Tunisian endemic plant to date. Based on the aforementioned results, the feasibility and readiness timescale for its sustainable exploitation was overviewed and re-evaluated herein, upgrading (>two-fold) its potential value for the medicinal-cosmetic, agro-alimentary, and ornamental-horticultural sectors.
在植物保护以及独特的被忽视和未充分利用的植物遗传资源可持续利用的背景下，本研究聚焦于突尼斯当地特有的黄香科（唇形科）。利用地理信息系统和在线数据库，首次生成了详细的特定分类群生态概况，阐明了其野生栖息地的温度和气候条件，并有助于研究温度如何影响其种子萌发，从而使其在人为环境中的种植成为可能。继本文首次报道的种子繁殖（15至25摄氏度时发芽率为77.5 - 81.25%）之后，可以开展特定物种的原地和迁地保护工作或可持续开发策略。本研究还首次报道了化学肥料和综合养分管理（INM）肥料如何影响其幼苗的生长和试种（INM更具优势）。本文首次报道的DNA条形码技术可能实现其可追溯性，有助于未来的产品设计。所采用的多学科方法为弥合迄今阻碍这种突尼斯当地特有植物保护工作和/或可持续开发的重要研究差距铺平了道路。基于上述结果，本文概述并重新评估了其可持续开发的可行性和准备时间尺度，提升了（超过两倍）其在医药化妆品、农业食品和观赏园艺领域的潜在价值。
