The plant hormone ethylene is an important signal in plant growth
responses to environmental cues. In vegetative growth, ethylene
is generally considered as a regulator of cell expansion, but a role
in the control of meristem growth has also been suggested based
on pharmacological experiments and ethylene-overproducing mutants.
In this study, we used transgenic ethylene-insensitive and
ethylene-overproducing hybrid aspen (Populus tremula × tremuloides)
in combination with experiments using an ethylene perception
inhibitor [1-methylcyclopropene (1-MCP)] to demonstrate
that endogenous ethylene produced in response to leaning
stimulates cell division in the cambial meristem. This ethylene-controlled
growth gives rise to the eccentricity of Populus stems
that is formed in association with tension wood.
