Proteomics evidences of a systemic response to desiccation in the resurrection plant Haberlea rhodopensis.


ABSTRACT: According to the systems biology approach, genomics tells what can happen, transcriptomics what appears to be happening, metabolomics what has happened and proteomics what makes it happen. Thereby, to get a better what makes resurrection plants extremely tolerant to drought, we explored changes in the resurrection proteome and cellular ultrastructure of Haberlea rhodopensis in response to desiccation. Because genomic and proteomic data concerning resurrection plants are limited, particularly for H. rhodopensis, we identified proteins based on previous transcriptomic studies. For the identified proteins, fold changes and differences in transcript levels between fresh and dry plants were analyzed; proteins significantly enriched in various biological processes and metabolic pathways were detected using metabolomic metadata. The results confirmed that the transcription of different genes is regulated as previously described at the proteomic level; new genes were identified in desiccation tolerance, posttranscriptional regulation events, and posttranslational regulation events. We revealed new evidences about organelle and cell preservation, posttranscriptional and posttranslational regulation, photosynthesis, primary metabolism, and phagocytosis in H. rhodopensis. These findings can inform further genomic and evolutionary studies, as well as targeted genetic engineering to improve drought tolerance in crops as a response to climate change.
