The AT-hook containing proteins SOB3/AHL29 and ESC/AHL27 are negative modulators of hypocotyl growth in Arabidopsis.

摘要

As sessile organisms, plants have evolved elaborate mechanisms to sense and respond to their environment. One of the most important environmental factors is light. SOB3, which encodes a member of a nuclear localized, plant-specific AT-hook motif containing protein family, was identified from an activation-tagging screen for suppressors of the long-hypocotyl phenotype of a weak phyB allele, phyB-4. sob3-D ( suppressor of phyB-4
