In this study, linalyl 6-O-α-arabinopyranosyl-β-d-glucopyranoside (linalyl β-vicianoside: LinVic) was synthesized, and a linalool diglycoside purified from soybean leaves was identified as LinVic by using liquid chromatography-mass spectrometry. High levels of LinVic were detected in leaves and sepals during soybean plant growth. The LinVic content did not significantly increase following methyl jasmonate treatment of the leaves, indicating that its synthesis is independent of the jasmonic acid signaling pathway. In addition to LinVic, soybean also contains 1-octen-3-yl primeveroside. We treated soybean leaves with vaporized linalool and 1-octen-3-ol to determine whether the glycosylation system discriminates between these 2 volatile alcohols. Linalool treatment resulted in the accumulation of LinVic, while 1-octen-3-ol treatment caused little change in the amount of 1-octen-3-yl primeveroside, suggesting discrimination between these compounds. Linalool-treated soybean leaves exhibited increased resistance against common cutworms, indicating that LinVic may contribute to herbivore resistance.</p>","PeriodicalId":9175,"journal":{"name":"Bioscience, Biotechnology, and Biochemistry","volume":" ","pages":"33-40"},"PeriodicalIF":1.4,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142458214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To develop a protein production system under reduced methanol supply conditions, we attempted to characterize the AOX1 promoter induction activity by comparing derepression conditions with methanol induction conditions. This comparison is important because decreasing methanol consumption would enhance the industrial value of Ogataea minuta for heterologous protein production. For such a comparison, an alcohol oxidase-deficient (Δaox) strain was generated, with methanol only being used for AOX1 promoter induction.

Therefore, this study aimed to elucidate the function of MYB50 under ABA signaling.

Furthermore, ABA differentially regulates MYB50 compared with ABI5, another key transcription factor involved in root growth under ABA signaling, suggesting that ABA uses distinct regulatory pathways for root growth.
