Disease relevance of SUC2


High impact information on SUC2


Biological context of SUC2


Anatomical context of SUC2


Associations of SUC2 with chemical compounds


Regulatory relationships of SUC2

  • The overall pattern of SUC2-GUS expression correlated well with that of the Arabidopsis thaliana AHA3 plasma-membrane H(+)-ATPase which is also expressed in the phloem and most likely represents the primary pump generating the energy for secondary active transporters such as SUC2 [6].
