“…6) Yasuda et al have recently isolated strigol from an aseptic root culture of Menispermum dauricum DC., a Chinese medicinal, non-host plant. 7) Strigol is therefore produced by both host and non-host plants. In contrast to strigol, all of the other natural strigolactones characterized to date have only been isolated from host plants: sorgolactone from sorghum, 8) alectrol from cowpea, 9) and orobanchol from red clover.…”

“…For example, according to the estimate by Yasuda et al, they recovered only 2% of strigol originally present in a culture filtrate, the greatest loss occurring during the ODS-HPLC separation. 7) In the previous paper, a simple and rapid analytical method for known strigolactones using HPLC-tandem mass spectrometry (LC/MS/MS) was reported.…”

“…In the following years, the SL orobanchol was isolated from red clover (Yokota et al 1998), sorgomol from sorghum (Xie et al 2008b), and 5-deoxystrigol from L. japonicus (Akiyama et al 2005), sorghum, maize, pearl millet (Awad et al 2006), and several Fabaceae species . Many other SLs from host plants and root exudates of the nonhost plant white lupin or root culture of Menispermum dauricum (Yasuda et al 2003) were reported. According to the proposed SL biosynthetic pathway (Matusova et al 2005), 5-deoxystrigol might be a common precursor for SL.…”

Plants produce numerous secondary metabolites, many of which have a role in their development. The presence of such compounds in the rhizosphere led other organisms in the course of evolution to recognize these root exudates as signals for the presence of a host plant. Strigolactones (SLs) were recently identified as a new plant hormone. However, they were first identified, more than 40 years ago, as germination stimulants of the parasitic plants Striga and Orobanche, and later as stimulants of hyphal branching of the symbiotic arbuscular mycorrhizal fungi. In this chapter, we focus on SLs in root exudates as a signal in these parasitic and symbiotic interactions. The possible evolution of the biological role(s) of SLs, their essentialness to, and their involvement in determining host recognition by parasitic plants and symbiotic fungi will be discussed.

“…2). 12,27,[29][30][31][32][33][34][35] Although strigolactones are perhaps more widely distributed in the plant kingdom, the isolation and characterization of strigolactones in root exudates have been hampered by the extremely low concentrations produced and exuded by host roots and by their relative instability. Analysis using high-performance liquid chromatography (HPLC) connected to tandem mass spectrometry indicated the presence of several novel strigolactones, including one strigol isomer, two dehydro-strigol isomers, and four tetradehydro-strigol isomers, in the root exudates of soybean, carrot, tomato, sorghum, and pea.…”

Arbuscular mycorrhizae formed between more than 80% of land plants and arbuscular mycorrhizal (AM) fungi represent the most widespread symbiosis on the earth. AM fungi facilitate the uptake of soil nutrients, especially phosphate, by plants, and in return obtain carbohydrates from hosts. Apocarotenoids, oxidative cleavage products of carotenoids, have been found to play a critical role in the establishment of AM symbiosis. Strigolactones previously isolated as seed-germination stimulants for root parasitic weeds act as a chemical signal for AM fungi during presymbiotic stages. Stimulation of carotenoid metabolism, leading to massive accumulation of mycorradicin and cyclohexenone derivatives, occurs during root colonization by AM fungi. This review highlights research into the chemical identification of arbuscular mycorrhiza-related apocarotenoids and their role in the regulation and establishment of AM symbiosis conducted in the past 10 years.
