Canonical Strigolactones Are Not the Tillering-Inhibitory Hormone but Rhizospheric Signals in Rice

This study shows canonical strigolactones in rice are not responsible for shoot branching inhibition but act as rhizospheric signals to influence Striga germination and mycorrhizal colonization.

An ancestral function of strigolactones as symbiotic rhizosphere signals

This study identifies BSB, an ancestral strigolactone in bryophytes, which functions as a rhizosphere signal for AM symbiosis and was later co-opted as a plant hormone.

Asymbiotic mass production of the arbuscular mycorrhizal fungus Rhizophagus clarus

This study shows that combining strigolactone and methyl jasmonate with myristate and organic nitrogen in asymbiotic cultures of Rhizophagus clarus HR1 increases spore production and infectivity, supporting plant growth.

Myristate can be used as a carbon and energy source for the asymbiotic growth of arbuscular mycorrhizal fungi

This study shows that myristate supports asymbiotic growth of arbuscular mycorrhizal fungi by serving as a carbon and energy source.

Hydroxyl carlactone derivatives are predominant strigolactones in Arabidopsis

The paper identifies hydroxyl carlactone derivatives as the main strigolactones in Arabidopsis, showing their biosynthesis via MAX1 and LBO enzymes.

Chemical identification of 18-hydroxycarlactonoic acid as an LjMAX1 product and conversion of 18-hydroxylcarlactonoates to canonical and non-canonical strigolactones in Lotus japonicus

This study identifies LjMAX1 as the key enzyme in Lotus japonicus strigolactone biosynthesis, showing it converts carlactone to 18-hydroxycarlactonoic acid, a precursor for both canonical and non-canonical strigolactones.

Epidemiological survey of serum titers from adults against various Gram-negative bacterial V-antigens

The paper measures serum titers against five Gram-negative bacterial V-antigens in adults and finds high cross-correlation between some antigens, suggesting potential for epidemiological studies.

Which are major players, canonical or non-canonical strigolactones?

The paper compares canonical and non-canonical strigolactones, showing non-canonical ones are major germination stimulants in root exudates and likely the true shoot branching inhibitors.
