The non-coding spacers of psbK- psbI and trnH- psbA were the most polymorphic plastid sequences with variable sequence length in duckweeds (Table 1).
Among the most polymorphic genes sequenced were cytochrome P450 genes, lysozyme, translation initiation factor and ubiquitin conjugating genes.
Most intra-individual polymorphic sequences were polyphyletic, e.g. P. calleryana, P. xerophila, 'Nijisseiki' (P. pyrifolia) and 'Korlaxiangli' (P. sinkiangenesis).
They were also most polymorphic in terms of sequence divergence, and the group is lost in many lineages (only maintained in Lophopyrum, Crithiopsis, Dasypyrum, and D and various S genomes) or consists of pseudogenes only (U and M genome).
In this study we analyzed the vast dataset of human allelic variants (49 full coding sequences, 374 full exon 2 sequences) of the most polymorphic MHC class II locus, HLA-DRB1, and identified many previously unknown sequence features possibly contributing to the recombination.
As illustrated Fig. 9, we identified most polymorphic positions in the coding sequence (18 out of a total of 29 which are reported) among which 9 SNPs induce amino acid change.
Noncoding sequences are the most polymorphic, with a prevalence of indels over single nucleotide substitutions.
Sensitivity of rat macrophages to pyroptosis in response to LT is directly linked to the presence of certain short amino acid sequences at the most polymorphic site within the N-terminal NR100 domain.
The pspA gene was clearly the most polymorphic gene fragment among the variable gene sequences; however, other less well-characterized surface proteins were also quite genetically diverse.
The Block 2 region represents the most polymorphic part of the gene and its sequences may be grouped into one of the three allelic families or variants (K1, MAD20 and RO33) [ 10].
