“…From the existing 39 lavender species, the most commonly cultivated and researched species include L. angustifolia Mill., L. latifolia Medik., and L. x intermedia Emeric ex Loisel. A significant amount of research is also being conducted on L. stoechas L. and L. luisieri Rozeira [2,3]. Numerous cultivars have also arisen from standard breeding experiments [2].…”

“…From the over 39 lavender species identified, only a few, in particular L. angustifolia, L. x intermedia and L. latifolia, have been widely used for commercial cultivation [2,3,9,11]. The suitable cultivars have so far been chosen mainly based on their flowering season (early, mid or late season), oil yield and oil quality.…”

“…In this context, most L. x intermedia cultivars (e.g., Grosso) produce large biomass with high yields of flowers and oils which can be the preferable species for maximum production. L. angustifolia cultivars (e.g., Hidcote) consist of short-stemmed flowers producing low biomass with low yields of flowers and oils but are well-known by the high quality of the oils [2,3,11]. It should be noted that the phenotypic traits and biochemical compositions of the cultivars can be influenced by several environmental cues, including soil type, temperature, and light [12].…”

The global essential oil market has been steadily increasing in size over the past few years, and is estimated to reach ca. $7.5 billion USD per annum by 2018. Lavenders (Lavandula; Lamiaceae) contribute significantly to this market, yielding ca. 1500 tons of essential oils which are primarily used in cosmetics, personal care products, and medicines. Recent literature indicates that these oils may also have applications in food preservation and pest control, among others. The medicinal and pharmaceutical properties of lavenders are chiefly due their essential oils, in particular the major essential oil constituents linalool and linalyl acetate, although certain activities have been attributed to the phenolic compounds. In addition, there is evidence that the major and minor essential oil constituents act synergistically to provide various biological effects. A substantial amount of current research focuses on evaluating the biological activities of lavender essential oils for potential use in traditional and complementary medicine, food systems, cosmetic and fragrance formulations, and insect control products. This review examines recent progress in these areas, and highlights the current and future implications for these economically and medicinally valuable plants.

The diversification of animal-pollinated angiosperms is related to divergence in floral characteristics promoted by adaptations to different pollinators. According to prevailing evolutionary theory, this macroevolutionary pattern results from adaptive local or regional differentiation of pollination-related features in response to spatial divergence in pollinators. This crucial process links the micro- and macroevolution of floral adaptation, yet it has received much less attention than either floral diversification of species in a phylogenetic context, or pollinator-mediated phenotypic selection on pollination-related traits within populations. This chapter includes two components.

Decoupling subgenomes within hybrid lavandin provide new insights into speciation and monoterpenoid diversification of Lavandula

SummaryPolyploidization and transposon elements contribute to shape plant genome diversity and secondary metabolic variation in some edible crops. However, the specific contribution of these variations to the chemo‐diversity of Lamiaceae, particularly in economic shrubs, is still poorly documented. The rich essential oils (EOs) of Lavandula plants are distinguished by monoterpenoids among the main EO‐producing species, L. angustifolia (LA), L. × intermedia (LX) and L. latifolia (LL). Herein, the first allele‐aware chromosome‐level genome was assembled using a lavandin cultivar ‘Super’ and its hybrid origin was verified by two complete subgenomes (LX‐LA and LX‐LL). Genome‐wide phylogenetics confirmed that LL, like LA, underwent two lineage‐specific WGDs after the γ triplication event, and their speciation occurred after the last WGD. Chloroplast phylogenetic analysis indicated LA was the maternal source of ‘Super’, which produced premium EO (higher linalyl/lavandulyl acetate and lower 1,8‐cineole and camphor) close to LA. Gene expression, especially the monoterpenoid biosynthetic genes, showed bias to LX‐LA alleles. Asymmetric transposon insertions in two decoupling ‘Super’ subgenomes were responsible for speciation and monoterpenoid divergence of the progenitors. Both hybrid and parental evolutionary analysis revealed that LTR (long terminal repeat) retrotransposon associated with AAT gene loss cause no linalyl/lavandulyl acetate production in LL, and multi‐BDH copies retained by tandem duplication and DNA transposon resulted in higher camphor accumulation of LL. Advances in allelic variations of monoterpenoids have the potential to revolutionize future lavandin breeding and EO production.
