TI  - Telo boxes within the AGAMOUS second intron recruit histone 3 lysine 27 
      methylation to increase petal number in rose (Rosa chinensis) in response to low 
      temperatures.

AB  - The petals of rose (Rosa sp.) flowers determine the ornamental and industrial 
      worth of this species. The number of petals in roses was previously shown to be 
      subject to fluctuations in ambient temperature. However, the mechanisms by which 
      rose detects and responds to temperature changes are not entirely understood. In 
      this study, we identified short interstitial telomere motifs (telo boxes) in the 
      second intron of AGAMOUS (RcAG) from China rose (Rosa chinensis) that play an 
      essential role in precise temperature perception. The second intron of RcAG 
      harbors two telo boxes that recruit telomere repeat binding factors (RcTRBs), 
      which interact with CURLY LEAF (RcCLF) to compose a repressor complex. We show 
      that this complex suppresses RcAG expression when plants are subjected to low 
      temperatures via depositing H3K27me3 marks (trimethylation of lysine 27 on 
      histone H3) over the RcAG gene body. This regulatory mechanism explains the 
      low-temperature-dependent decrease in RcAG transcript levels, leading to the 
      production of more petals under these conditions. Our results underscore an 
      interesting intron-mediated regulatory mechanism governing RcAG expression, 
      enabling rose plants to perceive temperature cues and establish petal numbers.
