AB  - We recently identified a Citrus gene encoding SQUAMOSA PROMOTER BINDING 
      PROTEIN-LIKE (SPL) transcription factor that contained a sequence complementary 
      to miR156. Genes of the SPL family are known to play a role in flowering 
      regulation and phase transition. In Citrus, the mRNA levels of the gene were 
      significantly altered by fruit load in buds; under heavy fruit load (ON-Crop 
      trees), known to suppress next year flowering, the mRNA levels were 
      down-regulated, while fruit removal (de-fruiting), inducing next-year flowering, 
      resulted in its up-regulation. In the current work, we set on to study the 
      function of the gene. We showed that the Citrus SPL was able promote flowering 
      independently of photoperiod in Arabidopsis, while miR156 repressed its 
      flowering-promoting activity. In order to find out if fruit load affected the 
      expression of additional genes of the SPL family, we identified and classified 
      all SPL members in the Citrus genome, and studied their seasonal expression 
      patterns in buds and leaves, and in response to de-fruiting. Results showed that 
      two additional SPL-like genes and miR172, known to be induced by SPLs in 
      Arabidopsis, were altered by fruit load. The relationships between these factors 
      in relation to the fruit-load effect on Citrus flowering are discussed.
