生物多样性大数据时代已经导致理论和应用生物学，生态学和保护科学的快速，令人兴奋的进步。虽然有大量的遗传、地理和性状数据库，但这些数据库既不是完整的，也不是地球仪的随机样本。这些数据库中的差距和偏见降低了我们的推理和预测能力，这种不完整性更令人担忧，因为我们对它的种类和规模一无所知。我们进行了一个全面的检查，在最完整的植物基因，位置和功能性状的数据库的分类和空间采样。为此，我们从植物名录（分类学）、全球生物多样性信息设施（地点）、TRY（性状）和GenBank（基因）下载了数据。只有17.7%的世界上描述和接受的陆地植物物种在所有三个数据库中，这意味着超过82%的已知植物生物多样性在至少一个数据库中缺乏代表性。地理位置数据的物种覆盖率最高，遗传数据的物种覆盖率最低。苔藓植物和兰花在分类学上突出，赤道地区在空间上突出，在所有数据库中代表性很差。我们已经强调了一些分支和区域，我们知道很少的功能，空间和遗传，我们应该设定研究目标。科学界应该承认和奖励填补我们对生命之树的知识空白的重要价值，无论是对生物多样性科学还是保护。
The era of big biodiversity data has led to rapid, exciting advances in the theoretical and applied biological, ecological and conservation sciences. While large genetic, geographic and trait databases are available, these are neither complete nor random samples of the globe. Gaps and biases in these databases reduce our inferential and predictive power, and this incompleteness is even more worrisome because we are ignorant of both its kind and magnitude. We performed a comprehensive examination of the taxonomic and spatial sampling in the most complete current databases for plant genes, locations and functional traits. To do this, we downloaded data from The Plant List (taxonomy), the Global Biodiversity Information Facility (locations), TRY (traits) and GenBank (genes). Only 17.7% of the world's described and accepted land plant species feature in all three databases, meaning that more than 82% of known plant biodiversity lacks representation in at least one database. Species coverage is highest for location data and lowest for genetic data. Bryophytes and orchids stand out taxonomically and the equatorial region stands out spatially as poorly represented in all databases. We have highlighted a number of clades and regions about which we know little functionally, spatially and genetically, on which we should set research targets. The scientific community should recognize and reward the significant value, both for biodiversity science and conservation, of filling in these gaps in our knowledge of the plant tree of life.
