WebbTranslocation is the movement of organic compounds from where they are made at their source, to where they are required at their sink. It is an active process which can be used to transport phloem up or down the plant. … WebbThe current–voltage curves depicted in (A) demonstrate that in contrast to fou2 and ouf8, the wild-type TPC1 outward currents, reflecting K + uptake into the vacuole, are suppressed at high vacuolar Ca 2+ loads. Contrary to fou2 (D454N), the ability to release luminal K + into the cytosol via TPC1 channels (B) is impaired in the TPC1 pore-channel mutant ouf8 …
