“…CCD7 appears to be a biosynthetic cross point, controlling both strigolactone and AM-induced C 13 cyclohexenone and C 14 mycorradicin apocarotenoids (Vogel et al 2010). Finally, there are examples of cross talk where inhibition of ABA biosynthesis reduces CCD7 and CCD8 transcript abundance as well as strigolactone levels (López-Ráez et al 2010).…”

Abstract. Carotenoids are natural isoprenoid pigments that provide leaves, fruits, vegetables and flowers with distinctive yellow, orange and some reddish colours as well as several aromas in plants. Their bright colours serve as attractants for pollination and seed dispersal. Carotenoids comprise a large family of C 40 polyenes and are synthesised by all photosynthetic organisms, aphids, some bacteria and fungi alike. In animals carotenoid derivatives promote health, improve sexual behaviour and are essential for reproduction. As such, carotenoids are commercially important in agriculture, food, health and the cosmetic industries. In plants, carotenoids are essential components required for photosynthesis, photoprotection and the production of carotenoid-derived phytohormones, including ABA and strigolactone. The carotenoid biosynthetic pathway has been extensively studied in a range of organisms providing an almost complete pathway for carotenogenesis. A new wave in carotenoid biology has revealed implications for epigenetic and metabolic feedback control of carotenogenesis. Developmental and environmental signals can regulate carotenoid gene expression thereby affecting carotenoid accumulation. This review highlights mechanisms controlling (1) the first committed step in phytoene biosynthesis, (2) flux through the branch to synthesis of a-and b-carotenes and (3) metabolic feedback signalling within and between the carotenoid, MEP and ABA pathways.

“…Therefore, the results of Gray et al (2012) can now be reinterpreted as indirect effects of ABA, which require active strigolactone biosynthesis. Indeed, a complex interaction between ABA and strigolactones has been observed before (López-Ráez et al, 2010).…”

“…Endogenous strigolactone biosynthesis is dependent on biosynthesis enzymes carotenoid cleavage dioxygenases CCD7 and CCD8, which can be inhibited by the compound D2 (López-Ráez et al, 2010). To demonstrate that the SF observed is dependent on the endogenous strigolactone biosynthesis, seedlings were treated with 5 mM of D2 or mock treated with 5 mL/mL acetone.…”

Stromules are highly dynamic protrusions of the plastids in plants. Several factors, such as drought and light conditions, influence the stromule frequency (SF) in a positive or negative way. A relatively recently discovered class of plant hormones are the strigolactones; strigolactones inhibit branching of the shoots and promote beneficial interactions between roots and arbuscular mycorrhizal fungi. Here, we investigate the link between the formation of stromules and strigolactones. This research shows a strong link between strigolactones and the formation of stromules: SF correlates with strigolactone levels in the wild type and strigolactone mutants (max2-1 max3-9), and SF is stimulated by strigolactone GR24 and reduced by strigolactone inhibitor D2.

Strigolactones: A New Class of Plant Hormones with Multifaceted Roles

Strigolactones (SLs) are terpenoid lactones produced mainly in plant roots and initially identified as seed germination stimulants for parasitic weeds. In 2005, they were described also as boosters of hyphal branching in arbuscular mycorrhizal fungi, and thereby as promoters of arbuscular mycorrhizal symbiosis. In 2008, they emerged as a new class of plant hormones controlling plant architecture through repression of shoot branching. Since then, several new roles were discovered for SLs: in the adaptive responses to a number of environmental stimuli (including light, osmotic stress, interaction with pathogens and nodulating bacteria), and in several aspects of plant development (including seed germination for nonparasitic plants, hypocotyl elongation, reproduction, leaf senescence and nodulation). The biosynthetic and perception/transduction systems of SLs are being elucidated, and the first mechanistic models presented. Key Concepts: Strigolactones are the key nutrient allocators regulating plant development at the interface between plants, beneficial and detrimental (micro)organisms, and abiotic factors. Strigolactones induce hyphal branching in AM fungi and facilitate the establishment of symbiosis. Strigolactones inhibit shoot branching. Strigolactones affect root architecture and root development depending on nutrients availability. Synthetic SLs (analogues and mimics) are used in pharmacological applications to plants and fungi to decipher the structure–activity relationship. Structure–activity relationship (SAR): Different structures are tested for bioactivity in order to pinpoint which part of the molecule is essential for bioactivity and which can be considered only ‘decoration’.
