Gene Details:

• Gene ID:
• Gene Symbol: PagFBL1
• Gene Name: TRANSPORT INHIBITOR RESPONSE 1
• Genome:
• Species: Populus alba x Populus glandulosa

Functional Descriptions:

• The auxin receptor TIR1 homolog (PagFBL1) regulates adventitious rooting through interactions with Aux/IAA28 in Populus.
• Similar to the distribution pattern of auxin during initiation of adventitious roots, PagFBL1 expression was concentrated in the cambium and secondary phloem in stems during adventitious root induction and initiation phases, but decreased in emerging adventitious root primordia.
• Overexpressing PagFBL1 stimulated adventitious root formation and increased root biomass, while knock-down of PagFBL1 transcript levels delayed adventitious root formation and decreased root biomass.
• We propose that the PagFBL1-PagIAA28 module promotes adventitious rooting and could be targeted to improve Populus propagation by cuttings.
