phosphate/phosphate translocator (TPT) was isolated by reverse genetics. It contains a T‐
DNA insertion 24 bp upstream of the start ATG of the TPT gene. The mutant lacks TPT
transcripts and triose phosphate (TP)‐specific transport activities are reduced to below 5% of
the wild type. Analyses of diurnal variations in the contents of starch, soluble sugars and
phosphorylated intermediates combined with 14CO2 labelling studies showed, that the lack …
