Natural variation of rice strigolactone biosynthesis is associated with the deletion of two MAX1 orthologs
Open accessAbstract
Significance: Strigolactones are a new class of plant hormones regulating plant shoot and root architecture in response to the environment. Also present in root exudates, strigolactones stimulate the germination of parasitic plant seeds. This report describes a genomic polymorphism—associated with the Indica / Japonica subspecies divide in rice that has a major impact on the biosynthesis of strigolactones, plant tillering, and germination of the parasitic plant Striga hermonthica —consisting of the deletion of two strigolactone biosynthetic genes orthologous to Arabidopsis MAX1 . Both of these genes rescued the Arabidopsis max1-1 highly branched mutant phenotype and increased the strigolactone level when overexpressed in the Indica rice variety Bala. This finding is of great interest for plant physiologists, plant evolutionary biologists, and breeders.

The cultivar Bala exudes low SL levels from roots.
“Consistently, the cultivar Bala exudes low SL levels from roots (Cardoso et al., 2014).”
From Shaping plant architecture (2015) · cites this paper as Cardoso et al., 2014
SLB1 and SLB2 are present in the low-tillering cultivar Azucena (Japonica subspecies) and absent from the high-tillering cultivar Bala (Indica subspecies) due to a genomic rearrangement.
“They are present in the low-tillering cultivar Azucena (Japonica subspecies), while they are absent from the high-tillering cultivar Bala (Indica subspecies) due to a genomic rearrangement.”
From Shaping plant architecture (2015) · cites this paper as Cardoso et al., 2014
The rice cultivar Azucena, exhibiting high SL exudation, is more susceptible to Striga infection.
“SLs therefore induce germination of Striga seeds, which is in line with the finding that the rice cultivar Azucena, exhibiting high SL exudation, is more susceptible to Striga infection (Cardoso et al., 2014).”
From Shaping plant architecture (2015) · cites this paper as Cardoso et al., 2014
SLB1 and SLB2 show high orthology to the Arabidopsis SL biosynthesis gene MAX1 and are functional in Arabidopsis, since they can rescue the max1 mutant phenotype.
“Both genes show high orthology to the Arabidopsis SL biosynthesis gene MAX1 and are functional in Arabidopsis, since they can rescue the max1 mutant phenotype (Cardoso et al., 2014).”
From Shaping plant architecture (2015) · cites this paper as Cardoso et al., 2014
Cardoso et al. (2014) identified SLB1 and SLB2 as closely related genes by QTL mapping in rice.
“Cardoso et al. (2014) identified these closely related genes by QTL mapping in rice.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
