abstract = {Leaf growth dynamics are driven by diel rhythms. The
analysis of spatio-temporal leaf growth patterns in
Arabidopsis thaliana wild type and mutants of interest is a
promising approach to elucidate molecular mechanisms
controlling growth. The diel availability of carbohydrates
is thought to affect diel growth. A digital image sequence
processing (DISP)-based noninvasive technique for
visualizing and quantifying highly resolved spatio-temporal
leaf growth was adapted for the model plant A. thaliana.
Diel growth patterns were analysed for the wild type and for
a mutant with altered diel carbohydrate metabolism. A.
thaliana leaves showed highest relative growth rates (RGRs)
at dawn and lowest RGRs at the beginning of the night. Along
the lamina, a clear basipetal gradient of growth rate
distribution was found, similar to that in many other
dicotyledonous species. The starch-free 1 (stf1) mutant
revealed changed temporal growth patterns with reduced
nocturnal, and increased afternoon, growth activity. The
established DISP technique is presented as a valuable tool
to detect altered temporal growth patterns in A. thaliana
mutants. Endogenous changes in the diel carbohydrate
availability of the starch-free mutant clearly affected its
diel growth rhythms.},
