“…Some important residues included Cys47, His72, Glu73, Glu158, consistent with those identified in VvLIDH3 for substrate binding Cys36, His61, Glu62, Glu147 (Jia et al, 2015). Predictions of isoelectric point and other functional properties were also carried out in geranium (Narnoliya et al, 2018), followed by the identification of non-coding RNAs that may regulate expression of the gene (Narnoliya et al, 2019). Such information could assist functional analysis, mutagenesis and regulation studies of V. vinifera L-IDH.…”

Tartaric acid (TA) is an obscure end point to the catabolism of ascorbic acid (Asc). Here, it is proposed as a “specialized primary metabolite”, originating from carbohydrate metabolism but with restricted distribution within the plant kingdom and lack of known function in primary metabolic pathways. Grapes fall into the list of high TA-accumulators, with biosynthesis occurring in both leaf and berry. Very little is known of the TA biosynthetic pathway enzymes in any plant species, although recently some progress has been made in this space. New technologies in grapevine research such as the development of global co-expression network analysis tools and genome-wide association studies, should enable more rapid progress. There is also a lack of information regarding roles for this organic acid in plant metabolism. Therefore this review aims to briefly summarize current knowledge about the key intermediates and enzymes of TA biosynthesis in grapes and the regulation of its precursor, ascorbate, followed by speculative discussion around the potential roles of TA based on current knowledge of Asc metabolism, TA biosynthetic enzymes and other aspects of fruit metabolism.

“…L-Idonic acid is then oxidized by L-Idonic acid dehydrogenase (L-IdnDH) to 5-KGA, which is cleaved between C4 and C5 to form 4-carbon L-threo-tetruronate. This compound is further oxidized to yield TA [39]. However, the specific enzymes involved in the biosynthesis of TA in plants, including the functions of transketolase (TK) and tartaric acid semialdehyde dehydrogenase (TSAD) in the grapevine TA synthesis pathway, remain unverified and require indepth investigation.…”

Tartaric acid (TA) is the primary organic acid present in grapes and a fundamental constituent of wine, responsible for shaping its taste, aroma, and overall quality. This review presents a comprehensive overview of the advances made in previous investigations on grape tartaric acid. It elucidates the structural properties, distribution characteristics, biosynthesis, catabolism, and transcriptional regulation of grape tartaric acid, and also speculates on the regulatory mechanism of tartaric acid based on the modulation of ascorbic acid-related transcription factors. Furthermore, this review provides insights into the future research directions and objectives, with the goal of providing a reference for the analysis of the complete biosynthetic pathway of grape tartaric acid, thereby enabling precise regulation of tartaric acid.

“…These non-protein-coding transcripts target terpene biosynthesis pathway genes in rose-scented geranium species (Pelargonium spp.) [67]. In addition, miRNAs and lncRNAs regulate terpene trilactone (TTL) biosynthesis by targeting structural genes and TFs in Ginkgo biloba [68].…”

Volatile organic compounds (VOCs) are emitted by plants as a consequence of their interaction with biotic and abiotic factors, and have a very important role in plant evolution. Floral VOCs are often involved in defense and pollinator attraction. These interactions often change rapidly over time, so a quick response to those changes is required. Epigenetic factors, such as DNA methylation and histone modification, which regulate both genes and transcription factors, might trigger adaptive responses to these evolutionary pressures as well as regulating the rhythmic emission of VOCs through circadian clock regulation. In addition, transgenerational epigenetic effects and whole genome polyploidy could modify the generation of VOCs’ profiles of offspring, contributing to long-term evolutionary shifts. In this article, we review the available knowledge about the mechanisms that may act as epigenetic regulators of the main VOC biosynthetic pathways, and their importance in plant evolution.
