Effects of Extreme Rainstorms on Mycorrhizae of Alien and Native Plants in Abandoned Karst Farmlands
This study aimed to explore the responses of mycorrhizae of alien plants and native plants to the changes of rainstorm frequency in karst areas. Dominant alien plants and native plants from karst abandoned land under four rainfall treatments (natural rainfall (CK), low-frequency rainstorm (T20), medium-frequency rainstorm (T40), and high-frequency rainstorm (T60)) were used to determine the mycorrhizal colonization rate of plants, soil hyphal density, and spore density. The results showed: (1) Medium-frequency and high-frequency rainstorm treatments significantly increased the arbuscular colonization rate of native plants (P<0.05) and improved soil spore density, but decreased the arbuscular colonization rate of alien plants. Among them, the spore density of alien plants only increased under high-frequency rainstorm treatment. (2) Medium-frequency rainstorm treatment significantly reduced the hyphal density of native plants (P<0.05), while the hyphal density of alien plants showed no significant change. (3) Extreme rainstorm treatments reduced the number of plant species with mycorrhizal differences, and different plant species showed variations in their responses to extreme rainstorms. The results indicated that rainstorm frequency affected the mycorrhizal colonization characteristics differently for different plant species; native plants exhibited a more sensitive response to rainfall changes.

植物是入侵生物中种类和数量最多的类群，对入侵植物开展经济成本评估可为后续风险管理和相关政策的制定提供参考依据。本研究基于InvaCost数据库评估获得了1970-2017年全球入侵植物的经济成本，研究结果表明：1）入侵植物的保守经济成本为1943.65亿美元，年均40.49亿美元，其中，直接经济损失达1004.68亿美元，占比为51.69%；2）在64个国家和地区中，美国的经济成本最高，其次为澳大利亚，我国208.31亿美元（1407.07亿人民币）排名第三。凤眼莲是全球最昂贵的入侵植物种类，其危害所产生的成本高于排名5~10名的入侵植物成本之和；3）过去的近50年里，入侵植物的经济成本呈上升趋势，模型测算2017年入侵植物的可能成本为34.38亿~104.52亿美元，最高置信值为77.25亿美元。本研究有助于加深对入侵植物危害严重性的客观认识，可为我国开展更为积极的入侵植物治理提供科学依据。

More than two-thirds of terrestrial plants acquire nutrients by forming a symbiosis with arbuscular mycorrhizal (AM) fungi. AM fungal hyphae recruit distinct microbes into their hyphosphere, the narrow region of soil influenced by hyphal exudates. They thereby shape this so-called second genome of AM fungi, which significantly contributes to nutrient mobilization and turnover. We summarize current insights into characteristics of the hyphosphere microbiome and the role of hyphal exudates on orchestrating its composition. The hyphal exudates not only contain carbon-rich compounds but also promote bacterial growth and activity and influence the microbial community structure. These effects lead to shifts in function and cause changes in organic nutrient cycling, making the hyphosphere a unique and largely overlooked functional zone in ecosystems.Copyright © 2021 Elsevier Ltd.

The majority of plants live in close collaboration with a diversity of soil organisms among which arbuscular mycorrhizal fungi (AMF) play an essential role. Mycorrhizal symbioses contribute to plant growth and plant protection against various environmental stresses. Whereas the resistance mechanisms induced in mycorrhizal plants after exposure to abiotic stresses, such as drought, salinity and pollution, are well documented, the knowledge about the stress tolerance mechanisms implemented by the AMF themselves is limited. This review provides an overview of the impacts of various abiotic stresses (pollution, salinity, drought, extreme temperatures, CO2, calcareous, acidity) on biodiversity, abundance and development of AMF and examines the morphological, biochemical and molecular mechanisms implemented by AMF to survive in the presence of these stresses.

近年来，由于城市工业的不断发展和化学肥料的过度使用，土壤矿质元素匮乏以及污染等问题严重影响我国农业的可持续发展。丛枝菌根真菌(Arbuscular mycorrhizal fungi，AMF)作为天然的生物菌肥，可以有效促进植物对矿质元素的吸收并改善其生长状况，同时在重金属污染的土壤中又可以减轻重金属对植物的毒性，增强植物对环境变化的适应性。目前，AMF调控植物矿质元素吸收的生理及分子机制的研究已取得了重大进展，大量的菌根诱导基因被识别，但缺乏系统全面的总结。基于此，本文对国内外AMF调控植物矿质元素吸收的相关研究进行了归纳与总结，从AMF影响植物摄取大量元素和微量元素的生理机制及分子机理、AMF缓解植物重金属毒性的作用机制进行了综述,并根据现有研究的挑战与不足提出了展望，旨在为深入理解AMF影响植物对矿质元素的吸收机制和生物菌肥的农业应用等提供一定的科学依据。

Signaling through the Ror2 receptor tyrosine kinase promotes invadopodia formation for tumor invasion. Here, we identify intraflagellar transport 20 (IFT20) as a new target of this signaling in tumors that lack primary cilia, and find that IFT20 mediates the ability of Ror2 signaling to induce the invasiveness of these tumors. We also find that IFT20 regulates the nucleation of Golgi-derived microtubules by affecting the GM130-AKAP450 complex, which promotes Golgi ribbon formation in achieving polarized secretion for cell migration and invasion. Furthermore, IFT20 promotes the efficiency of transport through the Golgi complex. These findings shed new insights into how Ror2 signaling promotes tumor invasiveness, and also advance the understanding of how Golgi structure and transport can be regulated.

在自然土壤生态系统中,丛枝菌根(AM)真菌孢子的数量与菌根共生体的形成和分布具有密切的相关性,关注AM真菌孢子的形成与分布机制对于揭示菌根共生体的生态学功能具有重要意义。其中,探究外界环境因子对孢子分布的影响已经成为当前菌根生态学研究的热点问题之一。研究表明,影响孢子形成和分布的因素主要包括气候因子、土壤理化因子、草食动物、宿主植物种类以及耕作制度等。气候因子和季节动态是决定AM真菌孢子形成和分布的主要因子,它通过对AM真菌的直接作用,或者是通过对宿主植物的间接作用影响AM真菌的侵染、产孢和分布;土壤是孢子的天然培养基,土壤理化性状影响孢子分布的要素主要有土壤类型、pH值、土壤湿度、通透性、营养元素含量以及土壤微生物等;宿主植物类型、草食动物和农业耕作措施通过对菌丝体的作用影响AM真菌孢子的群落动态。基于此,本研究围绕以上生态环境因子及其相互协同作用对AM真菌孢子形成和分布的作用机制进行了论述,并就未来AM真菌孢子的群落动态研究进行了展望。

\n Spores of the arbuscular mycorrhizal fungi (AMF)\n Glomus geosporum\n and\n Glomus constrictum\n were harvested from single-spore-derived pot cultures with either\n Plantago lanceolata\n or\n Hieracium pilosella\n as host plants. PCR-denaturing gradient gel electrophoresis analysis revealed that the bacterial communities associated with the spores depended more on AMF than host plant identity. The composition of the bacterial populations linked to the spores could be predominantly influenced by a specific spore wall composition or AMF exudate rather than by specific root exudates. The majority of the bacterial sequences that were common to both\n G. geosporum\n and\n G. constrictum\n spores were affiliated with taxonomic groups known to degrade biopolymers (\n Cellvibrio\n,\n Chondromyces\n,\n Flexibacter\n,\n Lysobacter\n, and\n Pseudomonas\n ). Scanning electron microscopy of\n G. geosporum\n spores revealed that these bacteria are possibly feeding on the outer hyaline spore layer. The process of maturation and eventual germination of AMF spores might then benefit from the activity of the surface microorganisms degrading the outer hyaline wall layer.\n
