Sequence alignment analysis of the mUb and ubiquitin genes from different species such as pineapple, seringa and tobacco showed high identities of over 84%.
A candidate gene could be selected because of its' biological association with some disease or being congenerous to a known gene related to the disease.
They share sequence homology and show sequence similarity 89.1% and 70.1% to the LTR of rice retrotransposon RIRE8, respectively.SLTR1 and SLTR2 are of gypsy retrotransposons of rice.
