Transcriptome reprogramming at late stage of desiccation defines the resurrection behavior of Haberlea rhodopensis

Project description:Water shortage is a major factor that harms agriculture and ecosystems worldwide. Plants display various levels of tolerance to water deficit, but only resurrection plants can survive full desiccation of their vegetative tissues. Haberlea rhodopensis, an endemic plant of the Balkans, is one of the few resurrection plants found in Europe. We performed transcriptomic analyses of this species under slight, severe and full dehydration and recovery to investigate the dynamics of gene expression and associate them with existing physiological and metabolomics data. De novo assembly yielded a total of 142,479 unigenes with an average sequence length of 1,034 nt. Among them, 18,110 unigenes were differentially expressed. Hierarchical clustering of all differentially expressed genes resulted in seven clusters of dynamic expression patterns. The most significant expression changes, involving more than 15,000 genes, started at severe dehydration (~20% relative water content) and were partially maintained at full desiccation (<10% relative water content). More than a hundred pathways were enriched and functionally organized in a GO/pathway network at the severe dehydration stage. Transcriptomic changes in key pathways were analyzed and discussed in relation to metabolic processes, signal transduction, quality control of protein and DNA repair in this plant during dehydration and rehydration. Reprograming of the transcriptome occurs during severe dehydration, resulting in a profound alteration of metabolism toward alternative energy supply, hormone signal transduction, and prevention of DNA/protein damage under very low cellular water content, underlying the observed physiological and metabolic responses and the resurrection behavior of H. rhodopensis.

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

Project description: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.

A multi-omics angle sheds light on the molecular mechanisms underlying desiccation tolerance in Craterostigma plantagineum

Project description:The resurrection plant Craterostigma plantagineum possesses an extraordinary capacity to survive long-term desiccation. To enhance our understanding of this phenomenon, complementary transcriptome, soluble proteome and primary metabolome analyses were carried out on plant leaves collected at different physiological stages during a dehydration and rehydration cycle. Dynamic changes in transcript, protein and metabolite levels revealed a unique signature characterizing each stage

Project description:Transcriptional profiling of resurrection plant Boea hygrometrica comparing control untreated plants with plants treated with dehydration. Goal was to determine the different effects of desiccation with different rates, and drought acclimation on global gene expression in Boea hygrometrica . 8 conditions comparison: untreated plants vs. plants treated with rapid dehydration for 2h (RWC~80%) and 48h (RWC<10%), untreated plants vs.plants treated with slow dehydration for 5d (RWC~80%) and 14d (RWC<10%), untreated plants vs. drought acclimated plants treated with rapid dehydration for 2h (RWC~80%) and 48h (RWC<10%). Biological replicates: 3 control replicates, 3 treated replicates.
