“…King grass is a nutritionally rich and high-yielding forage grass, which can be harvested 5–8 times per year for 75–180 t, which makes it an important animal feed resource ( Botero-Londono et al, 2021 ; Long et al, 2022 ). In addition, king grass can absorb heavy metal ions from soil to purify soil ( Li et al, 2021 ), which is rich in lignocellulosic biomass and can also be used to produce ethanol ( Cardona et al, 2016 ). The growth of king grass is seasonal.…”

In order to better understand the effect of wilting treatment on silage, we study analyzed the fermentation quality of unwilted (CK) and wilted (WT) king grass silage, and the dynamic changes of microorganisms in silage and aerobic exposure. After 30 days of silage, WT silage significantly reduced the pH of the silage (p < 0.05) and increased the contents of lactic acid and acetic acid (p < 0.05), but did not reduce the content of Ammonia-N (p > 0.05). Wilting treatment increased bacterial and fungal diversity during silage but decreased fungal diversity during aerobic exposure. The relative abundance of Lactococcus and Enterococcus in wilting silage increased. In the aerobic exposure stage, the relative abundance of Klebsiella decreased, but the relative abundance of Enterobacter increased in wilting treatment silage. In addition, the relative abundance of Acinetobacter and Ignatzschineria increased after 5 days of aerobic exposure. In contrast with unwilted silage, wilting treatment silage after aerobic exposure had no Candida, but the relative abundance of Wickerhamomyces increased. The results showed that wilting treatment could raise the silage quality of king grass. However, WT silage did not inhibit the reproduction of harmful microorganisms during aerobic exposure and did not significantly improve the aerobic stability of silage.

“…Endophytes can effectively regulate the stress tolerance of hosts to abiotic stresses ( Table 2 ). Studies have shown that the diversity of endophytic communities or changes in metabolism have a significant impact on host adaptability to the environment ( Li et al, 2022 ). Some endophytes activate membrane receptor molecular mechanisms and signaling pathways, such as G-protein-coupled receptors ( GPCRs ), receptor-like kinases ( RLKs ), ion channels, and histidine kinases, when the host is exposed to salinity, temperature, drought, and heavy metal toxicity.…”

“…The genetics and metabolism of endophytes ameliorate and supplement the material metabolic pathway and related gene expression of their hosts ( Mei et al, 2019 ). Conversely, the host also creates a unique community structure and gene characteristics of endophytes ( Oukala et al, 2021 ; Li et al, 2022 ).…”

Endophytes is a kind of microorganism resource with great potential medicinal value. The interactions between endophytes and host not only promote the growth and development of each other but also drive the biosynthesis of many new medicinal active substances. In this review, we summarized recent reports related to the interactions between endophytes and hosts, mainly regarding the research progress of endophytes affecting the growth and development of host plants, physiological stress and the synthesis of new compounds. Then, we also discussed the positive effects of multiomics analysis on the interactions between endophytes and their hosts, as well as the application and development prospects of metabolites synthesized by symbiotic interactions. This review may provide a reference for the further development and utilization of endophytes and the study of their interactions with their hosts.

“…S. indica is phylogenetically similar to AMF [ 12 ], and it can colonize many host plants and positively affect plant growth and development under environmental stress [ 14 ]. As opposed to other root-colonizing microbes, such as Rhizobia, which are species-specific [ 15 ], S. indica coexists with more than 200 different plant species [ 16 ], in-cluding many drought-resistant shrubs and trees, annuals and perennials, angiosperms, bryophytes, pteridophytes, and gymnosperms [ 4 , 17 ]. A major advantage of S. indica over AMF is that it can be grown quickly in an artificial medium, making it useful as a biofertilizer in farmlands and gardens [ 18 , 19 ].…”

Plant stress is one of the biggest threats to crops, causing irreparable damage to farmers’ incomes; Therefore, finding suitable, affordable, and practical solutions will help the agricultural economy and prevent the loss of millions of tons of agricultural products. Scientists have taken significant steps toward improving farm productivity in the last few decades by discovering how beneficial soil microorganisms enhance plant resistance to environmental stresses. Among these microorganisms is Serendipita indica, which the benefits of coexisting this fungus with plant roots have been extensively explored in recent years. By investigating fungus specification and its effects on plants’ morphological, physiological, and molecular traits, the present study seeks to understand how Serendipita indica affects plant resistance to salinity and drought conditions. Furthermore, this study attempts to identify the unknown mechanisms of action of the coexistence of Serendipita indica with plants in the face of stress using information from previous studies. Thus, it provides a way for future research to assess the impact of this fungus on tackling environmental stresses and enhancing agricultural productivity.
