The results indicate that SOB3 and BR signaling converge to influence the transcription of hypocotyl growth-promoting SAUR19 subfamily members.
Title: Brassinosteroid signaling converges with SUPPRESSOR OF PHYTOCHROME B4-#3 to influence the expression of SMALL AUXIN UP RNA genes and hypocotyl growth.

Data show that the light-inducible AHL proteins ESCAROLA (ESC)/AHL27 and SUPPRESSOR OF PHYTOCHROME B-4 #3 (SOB3)/AHL29 bind directly to an scaffold/matrix attachment regions (S/MARs) region of the YUCCA 9 (YUC9) promoter and suppress its expression to inhibit hypocotyl growth in light-grown seedlings.
Title: Coordination of matrix attachment and ATP-dependent chromatin remodeling regulate auxin biosynthesis and Arabidopsis hypocotyl elongation.

SOB3 modulates hypocotyl elongation in young seedlings by directly repressing the transcription of genes associated with auxin signaling.
Title: SUPPRESSOR OF PHYTOCHROME B4-#3 Represses Genes Associated with Auxin Signaling to Modulate Hypocotyl Growth.

These data indicate that SOB3 and ESC act redundantly to modulate hypocotyl growth inhibition in response to light.[SOB3]
Title: The AT-hook-containing proteins SOB3/AHL29 and ESC/AHL27 are negative modulators of hypocotyl growth in Arabidopsis.
