Identification of a major QTL that alters flowering time at elevated [CO(2)] in Arabidopsis thaliana.

Background: The transition from vegetative to reproductive stages marks a major milestone in plant development. It is clear that global change factors (e.g.

Iron-induced turnover of the Arabidopsis IRON-REGULATED TRANSPORTER1 metal transporter requires lysine residues.

Iron is an essential micronutrient but is toxic if accumulated at high levels. Thus, iron uptake and distribution in plants are controlled by precise regulatory mechanisms. IRON-REGULATED TRANSPORTER1 (IRT1) is the major high affinity iron transporter responsible for iron uptake from the soil in Arabidopsis (Arabidopsis thaliana).
