The current state-of-the-art creates a sound basis for the preservation of unique species Cupressus dupreziana provided that targeted effort and care is devoted to the accomplishment of multiplication protocols. This review is to summarize known data on Cupressus dupreziana-specific characteristics, including abiotic stress resistance, and natural reproduction, and estimates the possibilities of ex situ conservation with an emphasis on the cultivation in vitro of this endangered species. As there is only limited information about the cultivation of C. dupreziana in vitro, we have included relevant data on the related species Cupressus sempervirens, where micropropagation techniques are well established, along with other information on species with similar fates and life strategies-Saharan olive Olea europaea subsp. laperrinei and myrtle Myrthus nivellei. The aim of this work is to enhance general understanding and to promote an interest in this relict plant species to contribute to more wide-ranging studies and to increase its chance of preservation. Besides others, reducing the number of species threatened with extinction is an essential and immediate task as high genetic variability of ecosystems is crucial for their stability under changing climatic conditions.
目前的最先进技术为保护独特物种柏拉木提供了坚实的基础，只要有针对性地努力并关注繁殖方案的实施。本综述旨在总结柏拉木特有特性的已知数据，包括抗非生物胁迫和自然繁殖，并评估其离体保存的可能性，重点是体外培养这种濒危物种。由于关于柏拉木体外培养的信息有限，我们还包括了相关的栽培物种海岸柏柏拉木的相关数据，其中微繁殖技术已经成熟，同时还包括了其他具有相似命运和生活策略的物种的信息——撒哈兰油橄榄和桃金娘。这项工作的目的是增强对这种遗留植物物种的一般认识和兴趣，以促进更广泛的研究，并增加其保存的机会。除其他外，减少濒危物种的数量是一项至关重要和紧迫的任务，因为生态系统的高遗传变异性对于它们在气候变化条件下的稳定性至关重要。
