Abstract
Plants contain three major growth-promoting
plant hormones: auxin, gibberellins (GAs),
and brassinosteroids (BRs), although other
hormones also promote growth in certain
circumstances. Possible interactions between
the major three growth hormones
have received much attention over the decades.
In 2012, three articles proposed that
the BRs and GAs can interact at the signaling
level (Bai et al., 2012; Gallego-Bartolome
et al., 2012; Li et al., 2012), and since then,
this has become an accepted model (Figure
1; Oh et al., 2014; Wang et al., 2014; Davie're
and Achard, 2016). This "signaling" model
posits that DELLA proteins, which are negative
regulators of GA signaling that are
degraded by bioactive GA, physically interact
with positive regulators of the BR response,
BZR1 proteins (Bai et al., 2012; Gallego-
Bartolome et al., 2012; Li et al., 2012). The
DELLA-BZR1 interaction interferes with the
function of BZR1 proteins, thereby reducing
growth.
