Stolons and rhizomes are modified stems that facilitate vegetative reproduction by maintaining hybrid genotypes. In stolon development, gibberellins and MADS box genes promote formation while the DELLA repressor inhibits it. Photoperiod plays a role in regulating stolon formation by controlling GA biosynthesis or balancing asexual and sexual reproduction modes.
Stolons and rhizomes are modified stems for vegetative reproduction. While stolons grow above the ground, rhizomes grow beneath the ground. Stolons and rhizomes maintain the genotypes of hybrids and hence are invaluable for agricultural propagation. Diploid strawberry is a model for studying stolon development. At the axillary meristems, gibberellins and MADS box gene SOLI promote stolon formation, while the DELLA repressor inhibits stolon development. Photoperiod regulates stolon formation through regulating GA biosynthesis or balancing asexual with sexual mode of reproduction in the axillary meristems. In rhizomatous wild rice, the BLADE-ON-PETIOLE gene promotes sheath-to-blade ratio to confer rhizome tip stiffness and support underground growth. Together, this review aims to encourage further investigations into stolon and rhizome to benefit agriculture and environment.
