A cursory comparison of the amino acid sequences for the four Ceratopteris alpha-tubulin genes (Fig.
An additional sequence identified as an alpha-tubulin sequence from Ceratopteris has been deposited in GenBank by a separate research group (Salmi et al.
A BLAST comparison of the four protein sequences for the Ceratopteris genes with other alpha-tubulin sequences recorded in GenBank reveals a somewhat diverse pattern (see the last column of Table 1).
For comparative purposes, BLAST searches were conducted for each of the known alpha-tubulin genes of Arabidopsis to determine what sequences from Arabidopsis or other organisms would show the highest similarities to each of these genes (data not shown).
To further compare the relative diversity of the Ceratopteris and Arabidopsis alpha-tubulin proteins, the sequences from the carboxy terminus region, which is considered to be highly variable in alpha-tubulin proteins (e.
richardii alpha-tubulin genes in relation to alpha-tubulin genes from other plant species.
Probings of parental and DHL DNAs with the DIG-labeled alpha-tubulin Cri_10_E18_SP6 cDNA clone yielded at least ca.
Mapping can be performed only for those parental alpha-tubulin gene copies contained in restriction fragments that are polymorphic between the two parents and that therefore segregate in the DHLs.
Because the alpha-tubulin clone used as a DIG-labeled probe here anneals to every alpha-tubulin gene copy with sufficient sequence identity, given the stringency conditions of our general mapping project, we cannot determine which of the genes in Table 1 are represented by respective markers H&E20046154_l, H20046154 2, and E20046154 2.
