(A. thaliana)
2. MOT2 from
Chlamydomonas
1. MOT1 and MOT2
from Arabidopsis
belong to the sulphate
transporter (SULTR)
family but lack STAS
domain necessary for
sulphate transport
2. MOT2 from
Chlamydomonas is
not homologous to
AtMOT2, and belongs
to major facilitator
superfamily

1. KCO family
members are dual
affinity and involved
in influx of Na+ and
efflux of K+
2. Members of
CNGC, HKT,
KUP/HAK/KT and
LCT1 are dual
affinity; play role in
influx of Na+, K+,
Ca2+
3. Na+/H+ exchangers
(NHXs) play role in
vacuolar
compartmentalization
of Na
4. Na+ efflux is
performed by K+ATPase and SOS1
