Transcription Factors: Their Role in the Regulation of Somatic Embryogenesis in Theobroma cacao L. and Other Species

Abstract

Transcription factors are proteins that help with the control and regulation in the transcription of the DNA to mRNA by binding to special DNA sequences. With the aim to understand more about gene transcription regulation in Theobroma cacao L., this review outlines the principal transcription factors that were reported in other plants especially Arabidopsis thaliana and attempts at looking for the homologies with transcription factors in T. cacao. The information cited in this work is about the initiation, development, and maturation of the cacao somatic embryos and other crops. It is important to underline that there are very few publications in T. cacao discussing transcription factors that control the somatic embryogenesis process, but there is some information about transcription factors in other crops that we have used as a guide to try to understand this process.
