Candidate PeGRASs for enhancing stress resistance were identified. Passion fruit (Passiflora edulis Sims) is a tropical fruit crop with significant edible and ornamental value, but its growth and development are highly sensitive to environmental conditions. The plant-specific GRAS gene family plays critical roles in regulating growth, development, and stress responses. Here, we performed the first comprehensive analysis of the GRAS gene family in passion fruit. A total of 29 GRAS genes were identified and named PeGRAS1 to PeGRAS29 based on their chromosomal locations. Phylogenetic analysis using GRAS proteins from passion fruit, Arabidopsis, and rice revealed that PeGRAS proteins could be classified into 10 subfamilies. Compared to Arabidopsis, passion fruit lacked members from the LAS subfamily but gained one GRAS member (PeGRAS9) clustered with the rice-specific Os4 subfamily. Structural analysis performed in silico revealed that most PeGRAS members were intron less and exhibited conserved motif patterns near the C-terminus, while the N-terminal regions varied in sequence length and composition. Members within certain subfamilies including DLT, PAT1, and LISCL with similar unstructured N-terminal regions and 3D structures, exhibited similar tissue-specific expression patterns. While PeGRAS members with difference in these structural features, even within the same subfamily (e.g., DELLA), displayed distinct expression patterns. These findings highlighted that the N-terminal regions of GRAS proteins may be critical for their specific functions. Moreover, many PeGRAS members, particularly those from the PAT1 subfamily, were widely involved in stress responses, with PeGRAS19 and PeGRAS26 likely playing roles in cold tolerance, and PeGRAS25 and PeGRAS28 in drought resistance. This study provides a foundation for further functional research on PeGRASs and offers potential candidates for molecular breeding aimed at enhancing stress tolerance in passion fruit.</p>","PeriodicalId":20204,"journal":{"name":"Plant Cell Reports","volume":"44 2","pages":"46"},"PeriodicalIF":5.3,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143066683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, RrUNE12 upregulates antioxidant-related genes and maintains ROS homeostasis, thereby improving tolerance to salt stress. L-ascorbic acid (AsA) plays an essential role in stress defense as a major antioxidant in plant cells. GDP-L-galactose pyrophosphatase 2 (RrGGP2) has been previously identified as the key structural gene operating in AsA overproduction in Rosa roxburghii fruit. However, the transcriptional regulation of RrGGP2 in response to abiotic stress is not fully elucidated. In this study, we identified a bHLH transcription factor, RrUNE12, whose transcription level significantly correlated with RrGGP2 abundance and AsA accumulation in developing fruit. RrUNE12 is localized in the nucleus and specifically binds to the promoter of RrGGP2 to promote its transcription. The overexpression or silencing of RrUNE12 in R. roxburghii fruit and fruit callus further confirmed that RrUNE12 positively regulated RrGGP2 transcription and AsA level. Different abiotic stress treatments indicated that RrUNE12 was greatly induced by salt. Exogenous NaCl treatment on the RrUNE12-overexpressing or RrUNE12-silencing fruits also led to enhanced transcripts abundance of both RrUNE12 and RrGGP2, compared to the treatment without adding NaCl. RrUNE12 overexpression in fruit callus alleviated salt stress damage by upregulating the expression of RrGGP2 and antioxidant-related genes. Additionally, stable overexpression of RrUNE12 in tomato plants resulted in a significant increase in AsA content and antioxidant capacity, accompanied by an increased resistance to the salt stress. Collectively, the results suggest that RrUNE12 functions as an activator of AsA biosynthesis in R. roxburghii fruit and plays a positive role in mitigating salt stress by increasing both AsA level and the oxidation resistance.</p>","PeriodicalId":20204,"journal":{"name":"Plant Cell Reports","volume":"44 2","pages":"42"},"PeriodicalIF":5.3,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143060365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
