Endophytic fungi are a polyphyletic group of fungi that colonize inter or intracellular spaces of plants establishing mutually beneficial relationship with plants. As they present a high potential for plant growth, they are often objective of biotechnological development, especially for their use in agriculture. However, a broader perspective of its effect remains unclear. So, this study aimed to analyze, through a meta-analytical review, the general effects of these organisms as plant growth promoters. The Scopus database was used, with the terms ((endophy* AND fung*) AND ("plant growth" OR "plant development" OR bioinoculant OR "biological inoculant")). The documents were filtered to keep only thos e relevant to the study, and statistical data was collected and analyzed using MetaWin software. Fifty-eight studies with 1004 tests were found. The effects were generally positive, i.e., the endophytic fungi could stimulate plant productivity in the tested plants (Effect size: +0.2784). It was possible to see that the endophytes had the best results when used in the soil, on plants in the monocot group, and on those with an annual life cycle. Fungi from the Saccharomycetes class performed best, especially regarding increasing plant height. Thus, endophytic fungi are promising candidates for plant growth, and further studies are required to understand the patterns with the best results.

生根生长：荟萃分析内生真菌在植物生长中的作用


内生真菌是一类多系真菌，它们定植于植物的细胞间或细胞内空间，与植物建立互利关系。由于它们具有很高的植物生长潜力，因此它们通常是生物技术开发的目标，特别是在农业中的应用。然而，其影响的更广泛视角仍不清楚。因此，本研究旨在通过荟萃分析来分析这些生物体作为植物生长促进剂的一般效果。使用 Scopus 数据库，术语为（（内生* AND 真菌*）AND（“植物生长”或“植物发育”或生物接种剂或“生物接种剂”））。文件经过过滤，仅保留与研究相关的文件，并使用 MetaWin 软件收集和分析统计数据。共找到 58 项研究和 1004 项测试。效果通常是积极的，即内生真菌可以刺激测试植物的植物生产力（效果大小：+0.2784）。可以看出，内生菌在土壤、单子叶植物和具有一年生命周期的植物上使用时具有最佳效果。酵母纲真菌表现最好，特别是在增加植物高度方面。因此，内生真菌是植物生长的有希望的候选者，需要进一步的研究来了解具有最佳结果的模式。
