“…In fact, the dizzying array of specialized metabolites found in plants has been suggested to serve an equally diverse range of functions. For example, many of the over 210,272 identified alkaloid, phenylpropanoid, and terpene natural products (Marienhagen and Bott, 2013;Buckingham, 2013) have been proposed to provide protection against biotic (i.e., microbial pathogens and herbivores; Davis and Croteau, 2000) and abiotic (i.e., UV irradiation; Gil et al, 2012) stresses, as well as to serve in attracting beneficial insect/microbe/animal associations (Gershenzon and Dudareva, 2007) and mediating plant-to-plant communication (Aharoni et al, 2003). Consistent with these notions is that the mechanisms responsible for these adaptations have been subject to evolutionary processes yielding, in the case of specialized metabolism, molecular changes in the genes encoding for the relevant biosynthetic enzymes and thus providing for changes in catalytic outcomes and chemical diversification.…”

Molecular Diversity of Terpene Synthases in the Liverwort Marchantia polymorpha

et al. 2016

Marchantia polymorpha is a basal terrestrial land plant, which like most liverworts accumulates structurally diverse terpenes believed to serve in deterring disease and herbivory. Previous studies have suggested that the mevalonate and methylerythritol phosphate pathways, present in evolutionarily diverged plants, are also operative in liverworts. However, the genes and enzymes responsible for the chemical diversity of terpenes have yet to be described. In this study, we resorted to a HMMER search tool to identify 17 putative terpene synthase genes from M. polymorpha transcriptomes. Functional characterization identified four diterpene synthase genes phylogenetically related to those found in diverged plants and nine rather unusual monoterpene and sesquiterpene synthase-like genes. The presence of separate monofunctional diterpene synthases for ent-copalyl diphosphate and ent-kaurene biosynthesis is similar to orthologs found in vascular plants, pushing the date of the underlying gene duplication and neofunctionalization of the ancestral diterpene synthase gene family to >400 million years ago. By contrast, the mono-and sesquiterpene synthases represent a distinct class of enzymes, not related to previously described plant terpene synthases and only distantly so to microbial-type terpene synthases. The absence of a Mg 2+ binding, aspartate-rich, DDXXD motif places these enzymes in a noncanonical family of terpene synthases.

“…In grapevine, the high UV-B doses reduce shoot length and leaf area, increase both leaf thickness [135] and accumulation of terpenes with antioxidant properties [136]. On the other hand, flavonol biosynthesis is dramatically activated under both high and low UV-B exposures in the berry skin [9,10].…”

Grapevine is one of the most abundant crops worldwide, with varieties destined for fresh and dry consumption, as well as wine production. Unfortunately, grapevine plants are affected by both biotic and abiotic stresses, generating significant economic losses. These conditions can negatively impact grape cultivation at different stages: plant and berry development during pre-and post-harvest, production, fresh fruit processing and export, along with wine quality. Most of the grapevine varieties are susceptible to several pathogens and within this chapter, particular attention is given to fungi (Botrytis cinerea and Erysiphe necator) and viruses, since they are a worldwide concern. Within the latter, special focus is given to the grapevine leafroll disease, a complex and destructive infection. On the other hand, abiotic stress is also relevant in grapevine, and in this chapter it will be exemplified by UV-B radiation and its impact on growth and fruit development, plant adaptive responses and its relationship with the quality of grape berries for winemaking. The main biotic and abiotic grapevine stress factors are reviewed in this chapter, considering a special focus on biotechnological approaches carried out in order to address them and minimize their detrimental consequences.

With increasing social concerns for healthy food, the studies on the cultivation of crops to increase accumulation of functional metabolites in crops have been investigated. Accumulation of the metabolites in crops is highly affected by various types of stress, such as nutrient deficiency, water deficit (WD), extreme temperature and UV-B radiation as well as their own life cycle. This review summarizes the previous studies on the effects of environmental stresses, especially WD and UV-B radiation, on accumulation of functional metabolites in crops. UV-B radiation and WD during specific period (mainly at maturation stage) activates the adaptation and/or defense system in crops, thereby increasing biosynthesis of the metabolites. Although WD and UV-B radiation tend to decrease in crop yield, the decrease can be compensated by the production of high value crops having high content of functional metabolites.
