Title

Other claims from this paper (11)
- Intervention effect Exogenous trehalose reduced root elongation.
- Intervention effect Exogenous trehalose induced starch accumulation in shoots.
- Intervention effect Sucrose with trehalose restored root elongation.
- Intervention effect Trehalose plus sucrose produced more starch than sucrose alone.
- Intervention effect Trehalose-treated seedlings showed increased ADP-glucose pyrophosphorylase activity.
- Intervention effect Trehalose induced ApL3 expression.
- Intervention effect Sucrose slightly induced ApL3 expression.
- Intervention effect Trehalose further increased ApL3 expression in the presence of sucrose.
- Intervention effect Trehalose induced AT-beta-Amy expression with sucrose.
- Intervention effect Trehalose alone did not induce AT-beta-Amy expression.
- Mechanism The authors suggest trehalose interferes with carbon allocation by inducing source-tissue starch synthesis.
