Abstract：
:Karrikins are butenolides in smoke and char that stimulate seed germination. Karrikin action in Arabidopsis requires the F-box protein MAX2 and the α/β-hydrolase KAI2, a paralogue of D14 that is required for perception of strigolactones (SL). SL response involves hydrolysis by D14, whereas karrikins bind to KAI2 without apparent hydrolysis. We discuss the current understanding of the mechanisms of karrikin perception and response. The usual function of KAI2 is unclear, but we hypothesise that the similarity between karrikins and the endogenous ligand for KAI2 made adaptation of some plants to karrikins possible.

杂志文章,评审abstract：:Messenger RNA (mRNA) can move through the vascular system in plants. Until recently the transport of mRNA had been demonstrated only for a few well-documented cases, leading to the suggestion that transport was selective and specific. The extent of this long-distance transport has now been shown to be on the genomic s...
