TL;DR: It is proposed that strigolactones act as a new hormone class—or their biosynthetic precursors—in regulating above-ground plant architecture, and also have a function in underground communication with other neighbouring organisms.

TL;DR: Evidence is provided that DWARF14 (D14) inhibits rice tillering and may act as a new compo-nent of the strigolactone-dependent branching inhibition pathway and it is proposed that D14 functions downstream of striglactone synthesis, as a component of hormone signaling or as an enzyme that participates in the conversion of strIGolactones to the bioactive form.

TL;DR: In this paper, the concept of apical dominance was applied to tiller bud outgrowth of rice and it was shown that D10 transcription might be a critical step in the regulation of the branching inhibitor pathway.

TL;DR: It is suggested that tillering dwarf mutants are suitable for the study of bud activity control in rice and believe that future molecular and genetic studies using them may enable significant progress in understanding the control of tillering and shoot branching.

TL;DR: 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.
