conserved sequence

a NUCLEOTIDE SEQUENCE in a DNA or RNA molecule or an AMINO ACID SEQUENCE in a PROTEIN that has remained largely unchanged during evolution; the sequence being very similar between many species. Examples include sequences in PROMOTERS, RIBOSOMAL RNA, and in proteins involved in DNA REPLICATION. See also CONSENSUS SEQUENCE.

Until the availability of genomic sequence for model plants, comparative genomics approaches were successful for identifying homologues/ orthologues or cloning species-specific genes by using sequence conservation or synteny from model plant systems.
However, the sequences of pig lncRNAs are difficult to infer from other mammalian genomes because of the low sequence conservation of lncRNAs, which causes them to be mistaken for transcriptional noise [1].
Depending on the USUV strain, the nucleotide sequence similarity ranged from 81% to 98%, whereas amino acid sequence conservation ranged from 94.7% to 99.2% (Table 1).
Therefore, sequence conservation of lectin genes need to be studied for an in-depth learning of its roles in insect resistance.
However, strong DNA sequence conservation is not observed among DHS sequences, suggesting that it is difficult to computationally identify DHS from primary DNA sequence.
