Brassinosteroids are involved in response of cucumber (Cucumis sativus) to iron deficiency.

ABSTRACT:

Background and aims

Brassinosteroids (BR) are a class of plant polyhydroxysteroids with diverse functions in plant growth and development. However, there is little information on the role of BRs played in the response to nutrient deficiency.

Methods

To evaluate the role of BR in the response of plants to iron (Fe) deficiency, the effect of 24-epibrassinolide (EBR) on ferric reductase (FRO) activity, acidification of the rhizosphere and Fe content in cucumber (Cucumis sativus) seedlings under Fe-deficient (1 µm FeEDTA) and Fe-sufficient (50 µm FeEDTA) conditions were investigated.

Key results

There was a significant increase in FRO activity upon exposure of cucumber seedlings to an Fe-deficient medium, and the Fe deficiency-induced increase in FRO activity was substant
