Tóm tắt

The trehalose-6-phosphate synthase (TPS) proteins have been characterized to play an important role in numerous biological processes during the growth and development of plants. However, a comprehensive analysis of this important gene family is lacking for cassava (Manihot esculenta). The objective of this current study is to identify, annotate, and characterize the TPS genes (MeTPS) in cassava. A total of 12 MeTPS genes were identified in the cassava assembly. They were assigned to two different groups based on phylogeny. Our analyses indicated that these proteins shared slightly similar general features. Of our interest, the MeTPS genes exhibited divergent expression in major organs in cassava plants. Among them, MeTPS10 was noted to exhibit a high expression in fibrous root, lateral bud, petiole, and stem, while MeTPS11 was exclusively expressed in storage root tissues and strongly expressed in fibrous root and lateral bud tissues. Taken together, our study could provide a list of candidate MeTPS genes for further functional characterization.
