Coffea canephora, which belongs to the Rubiaceae family, is one of the most popular cultivated coffea worldwide. In this study, we identified and analyzed candidate genes that involved in auxinrelated gens in the C. canephora genome. The results showed that genome of C. canephora consists of 152 protein-coding genes related to auxin which are divided into 7 main groups depending on domain and motif: Auxin-induced protein
Auxin-binding protein
Auxin transporter-like protein
Auxin carrier component
Auxin response factor
Auxin-responsive protein
Auxin signaling protein. Using SMART software to analyze protein structure, the result indicated that there are some characteristic domains involved in auxin response such as EamA
AUX_IAA
Auxin inducible
Aldo_ket_red
Cupin
Aa_ trans
B3, Auxin_resp
Mem_trans
B561
GH3
and LRR domain. The study on candidate proteincoding genes relating to auxin is important for elucidating protein functions involved in various cellular processes, growth, development and climate change adaptation of C. canephora.
