• call: The other involves dipping the cut flowering shoots in a chemical called auxin, a plant hormone.

Adjective modifier

• synthetic: Populations resistant to synthetic auxins have also been identified.

Modifies a noun

• response: Currently, there is a BBSRC-funded project in the laboratory to investigate how ABA suppresses auxin responses in Arabidopsis roots.

• signal: Studies of the domain architecture imply that the gene normally functions as a negative regulator in auxin signaling by damping the positive auxin signals.

• receptor: References: Kepinski, S. and Leyser, O. ( 2005 ) The Arabidopsis F-box protein TIR1 is an auxin receptor.

• production: However, this study is the first to show what happens in a plant when auxin production is turned off.

• treatment: Other rapid changes occur in the nucleus where specific genes are up-regulated within five minutes of auxin treatment.

• level: Endogenous auxin levels are reasonable so the medium need not contain this.

Noun used with modifier

• hormone: The plant hormone auxin ( see Plant architecture ) appears to have a crucial role.

• plant: The plant hormone auxin ( see Plant architecture ) appears to have a crucial role.
