The biological diversity among Stramenopiles is striking; they range from large multicellular seaweeds to tiny unicellular species, they embrace many ecologically important algal (e.g., diatoms, brown algae), and heterotrophic (e.g., oomycetes) groups. Transcription factors (TFs) and transcription regulators (TRs) regulate spatial and temporal gene expression. A plethora of transcriptional regulatory proteins have been identified and classified into families on the basis of sequence similarity. The purpose of this work is to identify the TF and TR complement in diverse species belonging to Stramenopiles in order to understand how these regulators may contribute to the observed diversity.
Results
We identified and classified 63 TF and TR families in 11 species of Stramenopiles. In some species we found families with high relative importance, however, other species show homogenity across families. Taking into account the 63 TF and TR families identified, 28 TF and TR families were established to be positively correlated with specific traits like number of predicted proteins, number of flagella and number of cell types during the life cycle. Additionally, we found gains and several losses in TF and TR families specific to some species and clades, as well as, two family with high abundance specific to the autotrophic species and three family with high abundance specific to the heterotropic species.
Conclusions
For the first time, there is a systematic search of TF and TR families in Stramenopiles. The attempts to uncover relationships between these families and the complexity of this group may be of great impact, considering that there are several important pathogens of plants and animals, as well as, important species involved in carbon cycle. Speficific TF and TR families identified in this work appear to be correlated with particular traits in the Stramenopiles group, as well as, gains, losses and high abundance found in some TF and TR families may be correlated with the high complexity and diversity of the Stramenopiles.
