Abstract
Strigolactone (SL) and karrikin (KAR) signalling control many
aspects of plant growth and development through similar
mechanisms employing related a/b-fold hydrolase-receptors
and a common F-box protein named MORE AXILARY
GROWTH2 (MAX2) in Arabidopsis or DWARF3 (D3) in rice. D3
mediates SL-dependent ubiquitination and proteolysis of
DWARF53 (D53) protein, thought to be involved in the control
of gene expression, while a related protein SUPPRESSOR OF
MAX2-1 (SMAX1) is implicated in the response to KAR in
Arabidopsis. Different members of the D53/SMAX1 multigene
family likely mediate different responses in plant growth and
development. Analysis of responses to SL or KAR has
identified many genes regulated by these compounds.
Crosstalk with other signalling systems including light,
hormones and abiotic stress has also been identified. Here we
critically analyse how to progress towards a clearer
understanding of the targets and functions of the SL and KAR
signalling systems.
