Half-waterlogging stress driven transcriptome changes in Adiantum leaves. (A) Heat map representation of expression profiles for differentially regulated genes in response to 5 days of half-waterlogging stress. (B) Heat map representation of expression profiles for differentially regulated genes in response to 10 days of half-waterlogging stress. (C) Scatter plot showing the pathways to which the DEGs were significantly enriched after 5 days of half-waterlogging. (D) Scatter plot showing the pathways to which the DEGs were significantly enriched after 10 days of half-waterlogging. Where, CK = control, DW05 = half-waterlogging for 5 days, and DW10 = half-waterlogging for 10 days.

Introduction: Adiantum nelumboides (Adiantum) is an endangered fern with a narrow distribution along the Yangtze River in China. Due to its cliff-dwelling habit, it experiences water stress conditions, which further endangers its survival. However, no information is available about its molecular responses to drought and half-waterlogging conditions...

... Re-watering often (partially) reversed the changes of many metabolites induced by drought stress. However, notable differences were found between species (Liang et al., 2023;Shen et al., 2022;Warren et al., 2012). For instance, in some Eucalyptus species, further increases of some metabolites such as fructose, glucose and proto-quercitol decrease osmotic potential during re-watering, which are considered as helping plants cope with future water stress (Warren et al., 2012). ...
The Phyllanthus genus exhibits a broad distribution spanning across the majority of tropical and subtropical regions. Due to their ability to synthesize medicinal bioactive compounds such as lignans, they have been utilized historically in traditional medicine to treat a wide range of ailments. This review discusses the current knowledge on the potency of lignans for medicinal purposes, the benefit of lignans for plants, various lignans produced by Phyllanthus, and how lignan synthesis could be increased through biotic and abiotic elicitation. Finally, we present a set of connected hypotheses to explain how signaling crosstalk between endophytic microbes and drought stress responses regulates lignan production. Although the mechanisms of lignan synthesis in Phyllanthus are not fully explored, this review strongly supports the view that endophytic fungi and drought stress can increase lignan production in plants belonging to the genus Phyllanthus. The medicinal plant–endophyte–drought stress relationship helps to improve the lignan yield of Phyllanthus, which is crucial for human health and can be optimized under in vitro and in vivo conditions.
