However, the unpalatable flavor of emerging <em>D. oldhami</em> bamboo shoots has reduced consumer preference. The distinct flavor of bamboo shoots could potentially be attributed to the accumulation of differential metabolites linked to variations in bamboo shoots maturation, leading to a characteristic taste. In this study, to explore the molecular mechanisms underlying the formation of the flavor characteristics in bamboo shoots, we performed a joint transcriptomic and metabolomic analysis on the principal flavor components of <em>D. oldhami</em> (L) and <em>D. oldhami</em> ‘Hualvzhu’ (HL) bamboo shoots harvested at two developmental stages, unemerged and after emerging from the soil. Physiological analysis showed that HL presented a higher water content, lower lignin content, lower flavonoids content, a lower bitterness scoring value, and a higher sucrose content compared to L. LC-MS/MS analysis identified 23,064 primary-level differential metabolites from four comparison groups, and the differential accumulation patterns of ascorbic acid and sucrose were found to cause flavor differences. GO and KEGG enrichment analysis of the transcriptomic data demonstrated that ‘Biosynthesis of secondary metabolites’ and ‘Starch and sucrose metabolism’ were the major enrichment pathways. The expression levels of <em>GLDH</em>, <em>L-galDH1</em>, and <em>GME1</em> were positively correlated with ascorbic acid accumulation, whereas those of <em>SPS1</em>, <em>SPP1</em>, and <em>SPP2</em> were positively correlated with sucrose accumulation. Additionally, transcription factors like AP2/ERF, NAC, and GRAS were potentially involved in the biosynthesis of ascorbic acid and sucrose. Overall, our findings firstly uncovered the flavor formation mechanism of <em>D. oldhami</em> bamboo shoots, offering a theoretical basis for industrial growth.</div></div>","PeriodicalId":34477,"journal":{"name":"Food Chemistry Molecular Sciences","volume":"10 ","pages":"Article 100258"},"PeriodicalIF":4.1,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143907641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, improving its nutritional quality, including grain zinc (GZn), grain iron (GFe), kernel oil (KO), protein quality (PQ), and content (PC), is difficult due to the complex and polygenic nature of these traits. In traditional quantitative trait loci (QTLs) mapping, different populations tested across variable environments have resulted in heterogeneous findings, highlighting the challenge of QTL instability. Therefore, we tested whether Meta-QTL (MQTL) analysis enables the identification of stable QTLs with broader allelic coverage and higher mapping resolution for effective marker-assisted selection (MAS) of complex traits. A comprehensive literature search revealed 29 mapping studies encompassing 308 QTLs for the targeted traits. A total of 34 stable MQTLs were identified, with an average CI of 4.59 cM. These MQTLs were located on all ten maize chromosomes, with phenotypic variance explained (PVE %) ranging from 7.3 % (MQTL1_2) to 49.0 % (MQTL3_2). Furthermore, the analysis revealed six MAS-friendly and five hotspot MQTLs. Besides, 591 CGs were identified underlying these MQTLs, of which 14 have known roles in grain filling, metal homeostasis, and fatty acid biosynthesis in maize. In silico analysis confirmed the tissue-specific expression of these 14 CGs. MQTL analysis effectively refined the genomic regions (4.86 folds) linked with nutritional quality and identified stable MQTLs and CGs.
