The SWEET (sugars will be eventually exported transporters) family plays
important roles in various biological processes, such as plant growth,
development, and response to environmental conditions. Chu Duc Ha and
colleagues performed a comprehensive search of the cassava genome, leading
to the identification of 28 members of MeSWEET gene family. These genes were
distributed in 13 chromosomes out of 18 ones in cassava. Most of MeSWEET
genes had 6 exons, and this exon/intron organization was also previously
found in other plant species. The isoelectric point and prediction using
TargetP suggested that a majority of MeSWEET may be distributed on the
secretory pathway.

The results of the study provide insights on SWEET gene family in cassava,
thus serve as a basis for further functional research of such genes.
