Abstract:
We report the isolation and characterisation of
DKT1, a new carrot Kþ channel a-subunit belonging to the
Shaker-like family. DKT1 is expressed in many tissues of the
adult plant, suggesting that it may play important roles in both
nutrition and other important physiological processes. During
embryo development, DKT1 is expressed at later phases
implying the involvement of Kþ in embryo maturation. When
co-expressed with KDC1 in Xenopus oocytes, DKT1 is able to
form functional, heteromeric channels, suggesting that possible
interactions between these two ion channels in plant tissues may
modulate Kþ uptake.
