This study raised a hypothesis of geographically isolated <em>P</em>. <em>sarmentosum</em> plants possessing potential site- or/and plant-dependent accumulating metabolites, expressing genes, and colonizing bacteria. Here, <em>P</em>. <em>sarmentosum</em> plants of Guangzhou City (PG, comparison group) and Hainan Island (PH, control group) were collected for assaying leaf metabolomes (LMs), leaf transcriptomes (LTs), and leaf-assembled bacterial communities (LABCs), respectively. In LMs and LTs, 930 metabolites and 82,606 unigenes were identified with 552 differently accumulated metabolites (DAMs) and 28,177 differently expressed genes (DEGs), respectively. In LABCs, cluster analysis yielded 822 PG-PH-common, 1114 PG-unique, and 203 PH-unique operational taxonomic units (OTUs). In contrast of PH-LMs, the elevated accumulations of alkaloids and lipids and the decreased accumulations of flavonoids and phenolic acids were observed in PG-LMs. Typically, the DAMs and DEGs were co-enriched in two metabolic pathways of phenylpropanoids and flavonoids, visibly displaying the related DEGs, such as chalcone synthase (<em>CHS</em>), chalcone isomerase (<em>CHI</em>) and phenylalanine amino lyase (<em>PAL</em>), with regulating the functional DAMs, such as phenylalanine, tyrosine, p-coumaric acid, and naringenin. Noticeably, these DAMs were also significantly correlated with a number of different types or/and abundances of leaf-assembled bacteria (DTAB) between PG- and PH-LABCs, such as <em>Flavobacterium</em> and <em>Pseudomonas</em>. Therefore, this study clearly elucidated the functional metabolite accumulations and the close relationships with plant mRNA expressions and bacterial colonizations in geographically isolated plants of <em>P. sarmentosum</em>, providing new insight of selectively utilizing leaf food- and medicine-associated metabolites in different habitats of edible medicinal plants.</div></div>","PeriodicalId":16808,"journal":{"name":"Journal of plant physiology","volume":"310 ","pages":"Article 154512"},"PeriodicalIF":4.0,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143932248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to assess the growth and nutritional profiles of <em>P. aculeata</em> and <em>P. bahiensis</em> under water deficit, SA, and SNP, testing whether <em>P. bahiensis</em> also holds food potential and whether these treatments enhance antioxidant capacity.

Additionally, plants were foliar sprayed with 100 μM SA, 100 μM SNP, or water (control). <em>P. bahiensis</em> exhibited greater phenolic compounds content and antioxidant capacity, but lower biomass production, and contents of sugars and minerals compared to <em>P. aculeata</em>. Drought increased the antioxidant capacity but decreased mineral content and biomass in the two <em>species;</em> while SA and SNP only affected Mn contents, not affecting the antioxidant capacity and growth. These findings highlight the great antioxidant capacity of <em>P. bahiensis</em>, surpassing that of <em>P. aculeata</em>, which underscores its potential as a nutraceutical plant.

Under drought stress, overactivation of the photosynthetic electron transfer chain leads to excessive light energy absorption, resulting in photooxidative damage to crops.

However, the role of the xanthophyll cycle pigments and photosynthetic electron transport in the process of galactolipid modification alleviates drought-induced leaf senescence has not yet been clarified clearly. In this study, a comparative experiment was conducted to investigate changes in the xanthophyll cycle and photosynthetic electron transport during drought and re-watering in two maize varieties: a drought-tolerant variety (Liangyu66) and a senescent variety (Liangyu99). Drought stress induced more severely wilted and leaf senescence in Liangyu99, with lower shoot biomass, photosynthetic rate, chlorophyll <em>a</em>/b, monogalactosyldiacylglycerol (MGDG), digalactosyldiacylglycerol (DGDG) content, corresponding gene expression level and DGDG/MGDG ratio compared to Liangyu66.

Notably, the de-epoxidation state of the xanthophyll cycle (A + Z)/(A + Z + V) was significantly higher in Liangyu66 than in Liangyu99.
