Abstract
Akebia trifoliata is an economically important self-incompatible fruit tree in the family Lardiza-balaceae. Asexual propagation is the main strategy used to maintain excellent agronomic traits. However, the generation of adventitious roots during asexual propagation is very difficult. To study the important role of the WUSCHEL-related homeobox (WOX) transcription factor in fruit and adventitious root growth and development, we characterized this transcription factor family in the whole genome of A. trifoliata. A total of 10 AktWOXs were identified, with the fol-lowing characteristics: length (657~11328 bp), exon number (2~5), isoelectric point (5.65~9.03), amino acid number (176~361 AA), and molecular weight (20.500~40.173 kDa). 10 AktWOXs were classified into modern (6), intermediate (2), and ancient clades (2) and that all AktWOXs had undergone strong purifying selection during evolution. The expression profile of AktWOXs dur-ing A. trifoliata fruit development and adventitious root formation indicated that AktWOXs are widely involved in the development of the three fruit tissues, flesh, seeds and rind, and play an important role in the regulation of adventitious root development. Overall, this is the first study to identify and characterize the WOX family in A. trifoliata and will be helpful for further re-search on A. trifoliata fruit development and adventitious root formation.
