  1. Linkage groups of pearl millet represented as Pg_1 = LG1, Pg_2 = LG2, Pg_3 = LG3, Pg_4 = LG4, Pg_5 = LG5, Pg_6 = LG6, Pg_7 = LG7 and Pg_A = LGA, Chromosomes of foxtail millet named as Si_1 to Si_9, chromosomes of rice as Os_01 to Os_12, chromosomes of sorghum as SBI-01 to SBI-10, chromosomes of maize as Zm_01 to Zm_10 and chromosomes of Brachypodium as Bd_1 to Bd_5. The numbers in the brackets indicate the number of pearl millet TUSs containing mapped EST-SSR markers that had significant BLAST hits (e-value ≤ 1E-10) on the chromosome sequences of other grasses when BLAST search was done separately for each grass genome.
