“…Seasonal differences in GRSP content can indicate the AMF activity in the plant rhizosphere. In previous studies, the GRSP level was higher in the rainy season than in the dry season ( Reyes et al., 2019 ; Silva et al., 2020 ). In this study, the soil EEG content was significantly higher in autumn.…”

IntroductionPoplar is a tree species with important production and application value. The symbiotic relationship between poplar and arbuscular mycorrhizal fungi (AMF) has a key role in ecosystem functioning. However, there remain questions concerning the seasonal dynamics of the AMF community in poplar roots, the relationship between AMF and the soil environment, and its ecological function.MethodPoplar roots and rhizosphere soil were sampled at the end of April and the end of October. The responses of AMF communities to season, host age, and host species were investigated; the soil environmental factors driving community changes were analyzed.ResultsThe diversity and species composition of the AMF community were higher in autumn than in spring. Season, host age, host species, and soil environmental factors affected the formation of the symbiotic mycorrhizal system and the AMF community. Differences in the communities could be explained by soil pH, total nitrogen, total phosphorus, total potassium, available potassium, and glomalin content.DiscussionThe AMF community was sensitive to changes in soil physicochemical properties caused by seasonal dynamics, particularly total potassium. The change in the mycorrhizal symbiotic system was closely related to the growth and development of poplar trees.

“…However, no significant difference was found in T-GRSP content. T-GRSP reflects the accumulation of GRSP for a long time that it bounds to the soil particles more intrinsically [27]. AMF colonization showed non-significant positive correlation with EE-GRSP content (r = 0.453) but significant positive correlation with T-GRP content (0.632, p < 0.05).…”

“…Glomalin content from AMF was measured at the end of the second drought cycle according to [27] with some modifications. The glomalin quantification was divided into easily extractable-GRSP (EE-GRSP) and total-GRSP (T-GRSP) based on the difference of extraction conditions.…”

Chili pepper (Capsicum frutescens L.) is a common commodity used as spice and pharmaceutical uses around the world. However, chili pepper cultivation failure often occurs due to drought exposure. The inoculation of arbuscular mycorrhizal fungi (AMF), such as Funneliformis mosseae, has the potential to induce defense against drought stress through symbiotic association with plant roots. The aim of this research was to investigate the effects of F. mosseae inoculation on the growth of chili pepper under repeated drought stress. Chili pepper plants were exposed to three drought regimes for two cycles, with one rewatering event between the cycles. The plant agronomic variables, physiological performance, and microorganism parameters were observed. The results showed that the plant height, fresh and dry shoot weight, along with fresh and dry root weight increased significantly with F. mosseae inoculation under repeated drought stress. The F. mosseae treatment also increased water relative content and decreased proline and lipid peroxidation significantly. Although drought exposure decreased the AMF root colonization rate, the total microbial activity and glomalin-related soil protein were still increased by the F. mosseae inoculation. However, F. mosseae inoculation was negatively correlated to the abundance of phosphate solubilizing microorganisms. The results suggested that F. mosseae gave positive effects on C. frutescens L. growth under repeated drought stress through induced morphological and physiological responses.
