Evolutionary history of the Asr gene family

The Asr gene family is widespread in higher plants. Most Asr genes are up-regulated under different environmental stress conditions and during fruit ripening. ASR proteins are localized in the nucleus and their likely function is transcriptional regulation. In cultivated tomato, we identified a nove...

In this work we were able to expand our previous analysis for Asr2 and investigated the coding regions of the four known Asr paralogous genes in seven tomato species from different geographic locations.

Secondly, our study showed that Asr1 is highly conserved at both replacement and synonymous sites within the genus Lycopersicon. ASR1 protein sequence conservation might be associated with its multiple functions in different tissues while the low rate of synonymous substitutions suggests that silent variation in Asr1 is selectively constrained, which is probably related to its high expression levels. Finally, we found that Asr1 activation under water stress is not conserved between Lycopersicon species. © 2006 Elsevier B.V. All rights reserved. Fil:Frankel, N. Universidad de Buenos Aires.
