ORIGINAL PAPER PAV markers in Sorghum bicolour: genome pattern, affected genes and pathways, and genetic linkage map construction

centromeric regions. One of the prominent features of the PAVs is the high occurrence of long terminal repeats ret-rotransposons and DNA transposons. PAVs caused various alterations to gene structure, primarily including the cod-ing sequence variants, intron variants, transcript ablation, and initiator codon changes. The genes affected by PAVs were significantly enriched in those involved in stress responses and protein modification. We used 325 PAVs polymorphic between two sorghum inbred lines Ji2731 and E-Tian, together with 49 SSR markers, and constructed a genetic map, which consisted of 10 linkage groups corre-sponding to the 10 chromosomes of sorghum and spanned 1,430.3 cM in length covering 97 % of the physical genome. The resources reported here should be useful for genetic study and breeding of sorghum and related species
