DESCRIPTION:Plant species have evolved myriads of solutions\, including co
 mplex cell type development and regulation\, to adapt to dynamic environme
 nts. To understand this cellular diversity\, we profiled tomato root cell 
 type translatomes. Using xylem differentiation in tomato\, examples of fun
 ctional innovation\, repurposing and conservation of transcription factors
  are described\, relative to the model plant Arabidopsis. Repurposing and 
 innovation of genes are further observed within an exodermis regulatory ne
 twork and illustrate its function. Comparative translatome analyses of ric
 e\, tomato and Arabidopsis tissues suggest increased expression conservati
 on of root meristems compared with other homologous tissues. In addition\,
  the functions of constitutively expressed genes are more conserved than t
 hose of cell type/tissue-enriched genes. These observations suggest that h
 igher-order properties of cell type and pan-cell type regulation are evolu
 tionarily conserved between plants and animals.\n\nContact reception@plant
