-
↵Clones have been placed into 13 BLAST“categories” according to Figure 3. Some BLASTcategories have been further divided into “subcategories.” For each Cot library, the number (#) and percentage (%) of clones in aBLAST category/subcategory are given.
-
↵A literary reference (Ref.) or GenBank Accession number (Acc.) is given for the sequence or sequences in a subcategory.
-
↵Cot clones categorized as “Retroelements,” “MITEs,” and “Other dispersed repeats” collectively constitute “dispersed repeat sequences.”
-
↵Johnsongrass (Sorghum halepenese Pers.), an extremely aggressive weed, appears to be an interspecific hybrid descendant (autoallotetraploid) of S. bicolor and S. propinquum (Paterson et al. 1995).
-
Genomic sequence of uncertain character.
