To characterize the mtCOI haplotype, we used the following samples.
Sequences used in Nibouche et al obtained from GenBank
Alabama – Sorghum (2015), Johnsongrass (2016), sugarcane (2016)
Louisiana – Sugarcane (2016) – two populations
Texas – Sorghum (2013)
Florida – Sorghum and sugarcane (2013)

5. Importance of Clonal Characterizations
U.S. populations 2007
Clonal lineage on sorghum associated with haplotypes from West Africa, Australia and China.
Important to document clonal lineage used in laboratory studies.
