Arbuscular mycorrhizal fungi (AMF) are plant root symbionts that continuously carry thousands of nuclei in their spores and hyphae. This unique cellular biology raises fundamental questions regarding their nuclear dynamics. This review aims to address these by synthesizing current knowledge of nuclear content and behavior in these ubiquitous soil fungi. Overall, we find that that nuclear counts, as well as the nuclei shape and organization, vary drastically both within and among species in this group. By comparing these features with those of other fungi, we highlight unique aspects of the AMF nuclear biology that require further attention. The potential implications of the observed nuclear variability for the biology and evolution of these widespread plant symbionts are discussed.

丛枝菌根真菌中的核动力学。

丛枝菌根真菌(AMF)是植物根部共生体,在其孢子和菌丝中连续携带成千上万个核。这种独特的细胞生物学提出了有关其核动力学的基本问题。这篇综述旨在通过综合这些无处不在的土壤真菌中核含量和行为的当前知识来解决这些问题。总体而言,我们发现该组物种内和物种间的核数以及核的形状和组织都大不相同。通过将这些特征与其他真菌的特征进行比较,我们强调了AMF核生物学的独特方面,需要进一步关注。讨论了观察到的核变异性对这些广泛的植物共生体的生物学和进化的潜在影响。
