Alkali-salinity exerts severe osmotic, ionic, and high-pH stresses to plants. To under-stand the alkali-salinity responsive mechanisms underlying photosynthetic modulation and reactive oxygen species (ROS) homeostasis, physiological and diverse quantitative proteomics analyses of alkaligrass (Puccinellia tenuiflora) under Na2CO3 stress were conducted. In addition, Western blot,real-time PCR, and transgenic techniques were applied to validate the proteomic results and test the functions of the Na2CO3-responsive proteins. A total of 104 and 102 Na2CO3-responsive proteins were identified in leaves and chloroplasts, respectively. In addition, 84 Na2CO3-responsive phospho-proteins were identified, including 56 new phosphorylation sites in 56 phosphoproteins from chloro-plasts, which are crucial for the regulation of photosynthesis, ion transport, signal transduction, and energy homeostasis. A full-length PtFBA encoding an alkaligrass chloroplastic fructose-bisphosphate aldolase (FBA) was overexpressed in wild-type cells of cyanobacterium Synechocystis sp. Strain PCC 6803, leading to enhanced Na2CO3 tolerance. All these results indicate that thermal dissipation, state transition, cyclic electron transport, photorespiration, repair of pho-tosystem (PS) Ⅱ, PSI activity, and ROS homeostasis were altered in response to Na2CO3 stress, which help to improve our understanding of the Na2CO3-responsive mechanisms in halophytes.

Objective: The active components and potential targets were predicted and confirmed to explore the possible mechanism of Wenpi decoction on ulcer colitis. Methods: The traditional Chinese medicine integrated pharmacology platform (TCMIP) was used to construct the decoction-target-disease target network, and the key nodes were analyzed and screened. The function and pathway enrichment analysis were conducted to explore the biological processes, which Wenpi decoction may be involved in the treatment of ulcerative colitis. Results: The study showed that there were 455 active ingredients and 3044 targets in Wenpi decoction. The 434 targets and multiple biological processes and metabolic pathways were involved, such as chemokine signaling pathways, estrogen signaling pathway, thyroid hormone signaling pathway, MAPK signaling pathway, and PI3K/Akt signaling pathway. These targets and pathways were consistent with the pathogenesis of ulcerative colitis reported in the literature. In addition, Wenpi decoction was potential to be applied in the treatment of tumor, endocrine and metabolic diseases. Conclusions This study provided a scientific basis for further studies on the mechanism of Wenpi decoction in the treatment for ulcer colitis.
