“…According to the Chao1, ACE, Simpson, and Shannon indices of fungal communities at the 11 sites in coastal areas, the richness and diversity of the fungi at each site tended to be consistent. Compared with previous studies on fungal diversity in the coastal sediments of the East China Sea [ 44 ] and the mangrove sediments of the Maowei Sea in Guangxi [ 7 ], it was found that the fungal diversity in the East China Sea and the mangrove sediments of Guangxi was higher than that in the coastal areas of Guangdong, which might be related to the species diversity caused by different environments.…”

“…It was the only way for the construction of the Lingdingyang Sea Bridge. The high levels of TOC and TN might have also been due to frequent human activities [ 7 , 40 ]. The contents of total phosphorus at sites S2, S3, S5, and S6 were all at high levels, which might have been caused by human activities and excessive fertilization [ 43 ].…”

“…Fungi can contribute to the decomposition of organic matter, nitrogen fixation, and phosphorus dissolution, thereby promoting plant growth [ 7 ]. Many studies have confirmed that changes in fungal community composition are related to environmental factors such as salinity [ 8 ], dissolved oxygen [ 9 ], and the pollution of marine sediments [ 10 ].…”

“…Many studies have confirmed that changes in fungal community composition are related to environmental factors such as salinity [ 8 ], dissolved oxygen [ 9 ], and the pollution of marine sediments [ 10 ]. Moreover, human activities can cause changes in environmental factors, such as the release and transport of pollutants into the environment [ 7 , 11 ]. Recent studies have demonstrated that environmental changes influence the functional composition of fungi more precisely than their taxonomic composition [ 12 ], and changes in microbial function may be a more sensitive signal of environmental change.…”

As one core of the Guangdong–Hong Kong–Macao Greater Bay Area (GBA), Guangdong is facing some serious coastal environmental problems. Fungi are more vulnerable to changes in coastal environments than bacteria and archaea. This study investigated the fungal diversity and composition by high-throughput sequencing and detected basic parameters of seven environmental factors (temperature, dissolved oxygen, pH, salinity, total organic carbon, total nitrogen, and total phosphorus) at 11 sites. A total of 2056 fungal operational taxonomic units (OTUs) belonging to 147 genera in 6 phyla were recovered; Archaeorhizomyces (17.5%) and Aspergillus (14.19%) were the most dominant genera. Interestingly, a total of 14 genera represented the first reports of coastal fungi in this study. Furthermore, there were nine genera of fungi that were significantly correlated with environmental factors. FUNGuild analysis indicated that saprotrophs and pathogens were the two trophic types with the highest proportions. Saprotrophs were significantly correlated with total organic carbon (TOC), total nitrogen (TN), and total phosphorus (TP), while pathogens were significantly correlated with pH. This study provides new scientific data for the study of the diversity and composition of fungal communities in coastal ecosystems.

“…Dentiscutata heterogama is restricted in dry seasons while Acaulospora fungi are found in dry and rainy seasons [40]. Acaulospora species are thought to be relatively tolerant to flooding since they are reported as the dominant AMF and fungal genus in high-moisture soils [41,42]. These findings support the spatial existence of Dentiscutata heterogama and Acaulospora fungi in rice roots in non-flooded and flooded organic rice paddy soil.…”

Acaulospora as the Dominant Arbuscular Mycorrhizal Fungi in Organic Lowland Rice Paddies Improves Phosphorus Availability in Soils

Flooding in rainfed lowlands greatly impairs the mutualistic relationship between indigenous arbuscular mycorrhizal fungi (AMF) and rice. In flooded soils, root colonization by AMF is arrested, but some AMF genera, defined as the core AMF, remain present. However, the core AMF in rainfed lowlands and their symbiotic roles remain unknown. Here, we showed that Acaulospora fungi were the core AMF in rice seedling roots of the Sangyod Muang Phatthalung (SMP) landrace rice variety grown in non-flooded and flooded paddy soils. Subsequently, indigenous Acaulospora spores were propagated by trap cultures using maize as the host plants. Therefore, to clarify the roles of cultured Acaulospora spores in a symbiotic partnership, the model japonica rice variety Nipponbare was grown in sterile soil inoculated with Acaulospora spores, and recolonized with a native microbial filtrate from the organic rice paddy soil. Our data demonstrated that the inoculation of Acaulospora spores in well-drained soil under a nutrient-sufficient condition for six weeks enabled 70 percent of the rice roots to be colonized by the fungi, leading to higher phosphate (Pi) accumulation in the mycorrhizal roots. Unexpectedly, the growth of rice seedlings was significantly suppressed by inoculation while photosynthetic parameters such as fractions of incoming light energy and relative chlorophyll content were unaltered. In the soil, the Acaulospora fungi increased soil phosphorus (P) availability by enhancing the secretion of acid phosphatase in the mycorrhizal roots. The findings of this work elucidate the symbiotic roles of the dominant Acaulospora fungi from lowland rice paddies.
