Abstract
Plant cuticular wax plays an important role in resistance to environmental stresses. Eceriferum (CER) genes are involved in wax synthesis. However, little information is available for tomato species. In this study, 26 SlCER genes were identified in tomato (S. lycopersicum), and they were classified into four clades. The physicochemical properties and conserved motifs of their proteins were predicted. These SlCERs were mainly expressed in leaves, flowers or fruits, and most SlCERs played roles in response to abiotic stresses, especially drought stress. Furthermore, the changes in haplotypes indicated that SlCERs might have been involved in adapting to the environments for wild species S. pimpinellifolium before domestication. These findings would lay a foundation for future functional studies of SlCERs and also provide insights for anti-stress improvement in tomato in the near future.
