Karrikins (KARs) are a class of butenolide compounds found in smoke that were first
identified as seed germination stimulants for fire‐following species. Early studies of KARs …

Plants rely upon a diverse range of metabolites to control growth and development, and to
overcome stress that results from suboptimal conditions. Karrikins (KARs) are a class of …

The α/β hydrolase KARRIKIN INSENSITIVE 2 (KAI2) functions as a receptor for a yet
undiscovered phytohormone, provisionally termed KAI2 ligand (KL). In addition, it perceives …

The karrikin (KAR) receptor and several related signaling components have been identified
by forward genetic screening, but only a few studies have reported on upstream and …

Strigolactones (SLs) were initially discovered as germination inducers for root parasitic
plants. In 2015, three groups independently reported the characterization of the SL receptor …

Phtheirospermum japonicum, a member of the Orobanchaceae family, is a facultative root
parasitic plant that can survive without parasitizing the host. In contrast, obligate root …

Karrikins and strigolactones govern plant development and environmental responses
through closely related signaling pathways. The transcriptional repressor proteins …

The regulation of behavioral and developmental decisions by small molecules is common to
all domains of life. In plants, strigolactones and karrikins are butenolide growth regulators …

In this study, we investigated the potential role of the karrikin receptor KARRIKIN
INSENSITIVE2 (KAI2) in the response of Arabidopsis seedlings to high-temperature stress …

Strigolactones (SLs), long known as butenolide rhizospheric signals, have been recognized
since 2008 as a class of hormones regulating many aspects of plant development. Many …
