TI  - A temperature regime that disrupts clock-controlled starch mobilization induces 
      transient carbohydrate starvation, resulting in compact growth.

AB  - In nature plants are usually subjected to a light/temperature regime of warm day 
      and cold night (referred to as +DIF). Compared to growth under +DIF, Arabidopsis 
      plants show compact growth under the same photoperiod, but with an inverse 
      temperature regime (cold day and warm night: -DIF). Here we show that -DIF 
      differentially affects the phase and amplitude of core clock gene expression. 
      Under -DIF the phase of the morning clock gene CIRCADIAN CLOCK ASSOCIATED 1 
      (CCA1) is delayed, similar to that of plants grown on low sucrose. Indeed, under 
      -DIF carbohydrate (CHO) starvation marker genes are specifically upregulated at 
      the End of the Night (EN) in Arabidopsis rosettes. However, only in inner-rosette 
      tissue (small sink leaves and petioles of older leaves) sucrose levels are lower 
      under -DIF compared to under +DIF, suggesting that sucrose in source leaf blades 
      is not sensed for CHO status and that sucrose transport from source to sink may 
      be impaired at EN. CHO-starvation under -DIF correlated with increased starch 
      breakdown during the night and decreased starch accumulation during the day. 
      Moreover, we demonstrate that different ways of inducing CHO-starvation all link 
      to reduced growth of sink leaves. Practical implications for control of plant 
      growth in horticulture are discussed.
