The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Role of phytohormones in insect-specific plant reactions (2012, background): “The co-repressor TOPLESS (TPL) interacts with EAR-motif (ethylene-responsive element binding factor-associated amphiphilic repression) proteins to repress transcription of genes involved in several hormone pathways [71].”
Auxin receptors and plant development: a new signaling paradigm. (2008, background): “Recently, Szemenyei et al. (2008) found that Aux/IAA proteins interact with a transcriptional corepressor called TOPLESS (TPL).”
Auxin control of root development. (2010, background): “Domain I facilitates the interaction with TOPLESS1, a corepressor of transcription (Szemenyei et al. 2008), domain II creates a cooperative auxin-binding site with TIR1 (Tan et al.”
Hormone crosstalk in plant disease and defense: more than just jasmonate-salicylate antagonism. (2011, background): “TPL is a transcriptional corepressor that represses expression of auxin-responsive genes (186).”
Plant hormones are versatile chemical regulators of plant growth. (2009, background): “The Aux/IAA proteins bind to the ARFs and repress auxin-regulated transcription by recruiting a co-repressor called TOPLESS (TPL”
Auxin Response Factors — output control in auxin biology (2017, background): “It had previously been shown that Aux/IAA proteins recruit the co-repressor TOPLESS (TPL), and likely repress expression through histone de-acetylation (Long et al. , 2006; Szemenyei et al. , 2008).”
