“…Endogenous ABA levels in plants may increase rapidly in response to external stress such as drought, salinity, heat or environmental contaminants. 36 Under water stress, ABA signals plant leaves to take actions such as stomatal closure, reducing leaf expansion to reduce transpiration and thus avoid water loss. 37 It was also reported that ABA is involved in the modification of root architecture for adaption to drought 38 or N deficiency.…”

“…However, reported opposite results to those from our study. It is worth noting that about 20% of plant photosynthesis products can be transported to the soil around the roots through exudation patterns, and the availability of resources to the fungal community, as well as the ecological niche, may alter their interactions, leading to different results (Nehls et al, 2016;Vishwakarma et al, 2017;Fan et al, 2018).…”

Soil fungi play an important role in nutrient cycling, mycorrhizal symbiosis, antagonism against pathogens, and organic matter decomposition. However, our knowledge about the community characteristics of soil fungi in relation to bamboo varieties is still limited. Here, we compared the fungal communities in different soil compartments (rhizosphere vs. bulk soil) of moso bamboo (Phyllostachys edulis) and its four varieties using ITS high-throughput sequencing technology. The fungal α diversity (Shannon index) in bulk soil was significantly higher than that in rhizosphere soil, but it was not affected by bamboo variety or interactions between the soil compartment and bamboo variety. Soil compartment and bamboo variety together explained 31.74% of the variation in fungal community diversity. Soil compartment and bamboo variety were the key factors affecting the relative abundance of the major fungal taxa at the phylum and genus levels. Soil compartment mainly affected the relative abundance of the dominant fungal phylum, while bamboo variety primarily influenced the dominant fungal genus. Network analysis showed that the fungal network in rhizosphere soil was more complex, stable, and connected than that in bulk soil. A FUNGuild database analysis indicated that both soil compartment and bamboo variety affect fungal functions. Our findings provide new insights into the roles of both soil compartments and plant species (including variety) in shaping soil fungal communities.

“…Seed germination is usually accompanied by the increases in ABA catabolism (Vishwakarma et al, 2017), ABA signalling protein SNF1-RELATED PROTEIN KINASE2.2 (SnRK2.2) and SnRK2.3 inhibitor seed germination (Fujii et al, 2007). ABI1 and ABI2, type 2C protein phosphatases that interact with SnRK2 family, perform negative regulation of germination of seeds (Finkelstein and Somerville, 1990).…”

Seed germination, the first and critical step of the plant's life cycle, is affected by salt stress. However, the underlying mechanism of salt tolerance during early seed germination remains elusive. Here, a comparative RNA-seq analysis was performed using early germinating seeds either under normal conditions or in 100 and 150 mM sodium chloride. A total of 575 genes were up-regulated and 913 genes were down-regulated in the presence of 100 mM NaCl. Under the 150 mM NaCl treatment 1921 genes were up-regulated and 3501 genes were down-regulated. A total of 379 or 863 genes were up-regulated or down-regulated in both 100 and 150mM NaCl. These co-regulated genes were further analysed by GO enrichment. Genes in the categories abscisic acid signaling and synthesis and nutrient reservoir activity were significantly enriched in the up-regulated genes. Transcription factors responsive to gibberellin and auxin were significantly down-regulated by salinity stress. Genes related to anti-oxidant activity were significantly enriched in the down-regulated gene clusters by NaCl treatment. Our results suggest that salt stress inhibits seed germination by activating ABA synthesis and signalling, and depressing GA and auxin signalling, while preserving nutrition and down-regulated anti-oxidant activity. Our study provides more insight into the molecular mechanism of salt tolerance during early seed germination.
