“…This suggests there is a disconnect between sugar accumulation (TSS) and the accumulation of important varietal aromas. Our recent work confirmed this point; jasmonate application strongly enhanced terpene production while maintaining or reducing TSS (Wang et al 2022). The relationship of the above terpenes with the season (year) reflects the highly variable production of these compounds across seasons, which has been shown in several studies (Reynolds et al 1995, Luo et al 2019.…”

“…The only sesquiterpenes detected, farnesene‐a and farnesene‐b, were not affected by the CLM treatments. Most recently, Wang et al (2022) showed that jasmonate hormones significantly enhanced both monoterpene and sesquiterpene synthesis in Gewürztraminer grapes, in addition to upregulating the expression of these four genes. Together, this suggests the need for further exploration into the function/s of the specific TPSs in the production of mono and sesquiterpenes.…”

Background and Aims: Terpenes are volatile organic compounds that influence the composition of many winegrape cultivars. Terpene accumulation is variable between seasons and locations, influencing vintage composition. Crop load management (CLM) is a cultural practice utilised to improve grape composition; however, the impact of CLM on terpene biosynthesis and accumulation in winegrapes remains largely unknown. Methods and Results: Crop load management was applied to Gewürztraminer vines at two developmental stages: bunch closure [early (E)] and veraison [late (L)], and two crop loads: 50% removal [light crop (LC)] and 25% removal [medium crop (MC)] and compared to a Control [high crop (HC)] over three seasons. We considered early-harvest (22.5 Brix in HC) and harvest (23.4 Brix in HC) dates. The LC treatments improved TSS at both harvests; however, LC-E accelerated ripening compared to LC-L. The concentration of total free terpenes was highest in LC-E only at early-harvest. Free α-phellandrene, β-citronellol, geranic acid, geraniol, myrcene and nerol dictated this pattern. Although LC-E increased glycosylated geraniol at early-harvest, the concentration of total glycosylated terpenes was not altered. The expression of four terpene synthase (TPS) genes was increased by LC-E at early-harvest. Conclusions: The LC-E treatment accelerated technological maturity, and increased the expression of TPSs and free terpene accumulation at the early-harvest stage. Significance of the Study: This work provides valuable insight into the capacity of CLM to modulate terpenes in aromatic winegrapes.

Terpene volatiles define the flavor of terpenic grape cultivars. However, grape terpene concentrations can vary 2-to 3fold across seasons and vineyards, impacting vintage quality. The plant hormone methyl jasmonate (MeJA) stimulates grape terpene production but is expensive and can decrease berry weight and maturity. The synthetic jasmonate prohydrojasmon (PDJ) is costeffective yet has not been evaluated on grape maturity and terpene production. Here, we performed in vitro (berry culture) and in vivo (vineyard) experiments using Gewurztraminer (Vitis vinifera L.) to evaluate the time-and concentration-dependent sensitivity of maturity parameters and terpene content to MeJA and PDJ. In vitro berry weight was reduced by high MeJA and PDJ concentration across timings. Terpenes were most sensitive to low MeJA concentration at veraison (increased 24-fold) in vitro. Moderate PDJ concentration applied at veraison doubled (increased twofold) terpene concentration in vivo without impacting berry weight or maturity. In conclusion, PDJ may provide a solution to mitigate seasonal variability in terpene production in terpenic grape cultivars.

“…Otherwise, MeJA and IAA could also interact through the action of auxin response factor (ARF) to regulate the transcription of downstream auxin-dependent genes (Fattorini et al, 2018). Through these ways, but not only these, MeJA closely cooperates with IAA in regulating the formation and growth of adventitious roots formation (Gutjahr et al, 2005;Sharma et al, 2022;Wang et al, 2022). IAA in plants could affect the early division of plants, root elongation and the formation of tissues (Rui et al, 2020).…”

Exogenous phytohormones has become a common strategy to study plant stress and defense, which triggering complex and diverse cross-actions between endogenous phytohormones, which significantly regulate plant growth and defense. In this study, Methyl Jasmonate (MeJA) promoted the most obvious growth phenotype among four different exogenous phytohormones, especially promoted the growth of roots obviously. Subsequently, principal component analysis between physicochemical indexes and MeJA treatment suggested that MeJA promoted the growth of R. Roxburghii. MeJA could increase the contents of JA-Ile, IAA and triterpenoids. qPCR results showed that key genes in the JA signal transduction pathway up-regulated trends. And tryptophan synthesis genes, ANTHRANILATE AYNTHASE α1/β1 (ASA1/ASB1), IAA receptor protein gene TIR1, as well as the IAA polar transport protein gene PIN2 were all up-regulated by MeJA treatment. While, seven key genes of triterpene synthesis pathway performed a similar up-regulated trends. The results of the chord diagram analysis indicated there might be possible mutual regulation relationship among exogenous MeJA, endogenous JA-Ile, IAA and triterpenoids. The correlation analysis among triterpenoids, IAA and JA-Ile suggested that exogenous MeJA could promote the growth of Rosa Roxburghii through regulating the JA signal tranduction pathway, synthesis and transport of IAA. At the meanwhile, MeJA promoted the synthesis of triterpenoids which could not only regulate the root growth, but also make Rosa Roxburghii a certain defense ability. Finally, we speculate that exogenous MeJA pushed endogenous JA-Ile and IAA involved in regulated the metabolism of triterpenoids, they together regulated the positive growth of plants.
