A carotenoid-derived hormonal signal that inhibits shoot branching in plants has long escaped identification. Strigolactones are compounds thought to be derived from carotenoids and are known to trigger the germination of parasitic plant seeds and stimulate symbiotic fungi. Here we present evidence that carotenoid cleavage dioxygenase 8 shoot branching mutants of pea are strigolactone deficient and that strigolactone application restores the wild-type branching phenotype to ccd8 mutants…

Strigolactone Positively Controls Crown Root Elongation in Rice
TLDR
It is demonstrated that rice dwarf mutants that are strigolactone-deficient or -insensitive exhibit a short crown root phenotype, and it is shown that crown roots of wild type, but not dwarf mutants, become longer under phosphate starvation, implying that strIGolactones positively regulate the length of crown roots.
Does abscisic acid affect strigolactone biosynthesis?
TLDR
The results show a correlation between ABA levels and strigolactone production, and suggest a role for ABA in the regulation of striglactone biosynthesis, which is considered a novel class of plant hormones.
A tomato strigolactone-impaired mutant displays aberrant shoot morphology and plant interactions
TLDR
Characterization of the first tomato strigolactone-deficient mutant supports the putative general role of striglactones as messengers of suppression of lateral shoot branching in a diversity of plant species.
A petunia ABC protein controls strigolactone-dependent symbiotic signalling and branching
TLDR
It is shown that the Petunia hybrida ABC transporter PDR1 has a key role in regulating the development of arbuscular mycorrhizae and axillary branches, by functioning as a cellular strigolactone exporter.

Strigolactone Biosynthesis and Biology
TLDR
In this chapter, different aspects of the roles that strigolactones play both in the rhizosphere and during plant development are outlined andGene characterization in strIGolactone pathways and striglactone-related hormone cross-talk is addressed.
Methods for Phenotyping Shoot Branching and Testing Strigolactone Bioactivity for Shoot Branching in Arabidopsis and Pea.
TLDR
This chapter describes how to quantify the degree of shoot branching in two plant model species, Arabidopsis and pea, commonly used to decipher the control of this complex trait and proposes several methods to perform treatments of SL or SL analogs.
Strigolactones contribute to shoot elongation and to the formation of leaf margin serrations in Medicago truncatula R108.
TLDR
The contribution of strigolactones to the formation of leaf serrations in M. truncatula R108 line represents a novel function of these hormones, which has not been revealed by the analysis of strIGolactone mutants in other species.
Strigolactone, a key regulator of nutrient allocation in plants
TLDR
The physiological roles of SLs are focused on as a key regulator of nutrient allocation in plants, suggesting that plants produce SLs in response to nitrogen and phosphorus deficiency, stimulating changes in plant shoot and root architecture that enable them to adapt to environmental conditions.

Tomato strigolactones are derived from carotenoids and their biosynthesis is promoted by phosphate starvation.
TLDR
The results show that the AM branching factors and parasitic plant germination stimulants in tomato root exudate are strigolactones and that they are biosynthetically derived from carotenoids.
MAX4 and RMS1 are orthologous dioxygenase-like genes that regulate shoot branching in Arabidopsis and pea.
TLDR
MAX4 and RMS1 were found to encode orthologous, auxin-inducible members of the polyene dioxygenase family, suggesting that MAX4 is required to produce a mobile branch-inhibiting signal, acting downstream of auxin.
The Strigolactone Germination Stimulants of the Plant-Parasitic Striga and Orobanche spp. Are Derived from the Carotenoid Pathway1
TLDR
For these three host and two parasitic plant species, the strigolactone germination stimulants are derived from the carotenoid pathway, and this finding is discussed as an explanation for some phenomena that have been observed for the host-parasitic plant interaction.
The Branching Gene RAMOSUS1 Mediates Interactions among Two Novel Signals and Auxin in Pea
TLDR
The long-distance signaling network controlling branching in pea involves IAA, the RMS1 inhibitor, and an IAA-independent feedback signal, which cannot be achieved in wild-type plants by exogenous IAA application.
Production of Strigolactones by Arabidopsis thaliana responsible for Orobanche aegyptiaca seed germination
The germination stimulants produced by Arabidopsis thaliana, a host of root parasitic plants Orobanche spp. but not of arbuscular mycorrhizal (AM) fungi were examined. Root exudates from the
Strigolactones Stimulate Arbuscular Mycorrhizal Fungi by Activating Mitochondria
TLDR
It is concluded that strigolactones are important rhizospheric plant signals involved in stimulating both the pre-symbiotic growth of AM fungi and the germination of parasitic plants.
Long-distance signaling and the control of branching in the rms1 mutant of pea.
TLDR
The acropetal direction of transport of the Rms1 signal supports previous evidence that the rms1 lesion is not in an auxin biosynthesis or transport pathway and provides furtherevidence that the shoot has a major role in the regulation of branching and, moreover, that root-exported cytokinin is not the only graft-transmissible signal regulating branching in intact pea plants.
Micrografting techniques for testing long-distance signalling in Arabidopsis.
TLDR
A range of micrografting methods for young Arabidopsis seedlings are described, consistent with the concept that a branching signal is capable of moving from root to shoot, but not from shoot to shoot.
Plant sesquiterpenes induce hyphal branching in arbuscular mycorrhizal fungi
TLDR
Strigolactones are a group of sesquiterpene lactones, previously isolated as seed-germination stimulants for the parasitic weeds Striga and Orobanche, and a synthetic analogue, GR24, induced extensive hyphal branching in germinating spores of the AM fungus Gigaspora margarita at very low concentrations.
