AB  - Adaptation to environmental changes is an important fitness trait for crop 
      development. Photoperiod is an essential factor in seasonal control of flowering 
      time. Sensing of day-length requires an interaction between the Photoperiod and 
      the endogenous rhythms that is controlled by plant circadian clock. Thus, 
      circadian clock is a critical regulator and internal molecular time-keeping 
      mechanism, controlling key agricultural traits in crop plants such as the ability 
      to adjust their growth and physiology to anticipate diurnal environmental 
      changes. Here, we describe the gene Tomato Dof Daily Fluctuations 1 (TDDF1), 
      which is involved in circadian regulation and stress resistance. Large daily 
      oscillations in TDDF1 expression were retained after transferring to continuous 
      dark (DD) or light (LL) conditions. Interestingly, overexpressing TDDF1 induce 
      early flowering in tomato through up-regulation of the flowering-time control 
      genes, moreover, by protein-protein interaction with the floral inducer SFT gene. 
      Notably, overexpressing TDDF1 in tomato was associated with chlorophyll 
      overaccumulation by up-regulating the related biosynthetic genes. TDDF1 
      expression results in improved drought, salt, various hormones stress tolerance 
      alongwith resistance to late blight caused by Phytophthora infestans. This study 
      can be a distinctive strategy to improve other economically important crops.
