Phylogeny and expression pattern analysis of TCP transcription factors in cassava seedlings exposed to cold and/or drought stress.

ABSTRACT: The TCP transcription factors usually act as integrators of multiple growth regulatory and environmental stimuli. However, little is known about this gene family in the important tropical crop cassava (Manihot esculenta). In this study, 36 TCP genes were identified and renamed based on cassava whole-genome sequence and their sequence similarity with Arabidopsis TCPs. Typical TCP domains were detected in these proteins by multiple sequence alignment analysis. Evolutionary analysis indicated that MeTCPs could be divided into 8 subgroups, which was further supported by gene structure and conserved motif analyses. qRT-PCR analysis revealed tissue-specific and hormone-responsive expression patterns of MeTCP genes. Moreover, with global expression and promoter analysis, we found that MeTCPs show
