Response to successive desiccation/rehydration cycles of Coccomyxa solorinae-saccatae

Desiccation tolerance is relatively frequent in non-vascular plants and green algae. Over the last two decades, transcriptomic approaches have identified genes whose expression is induced by desiccation in diverse desiccation-tolerant taxa. However, the genes related with desiccation tolerance or transcriptional regulatory mechanisms in response to successive cycles of desiccation and rehydration have not yet been comprehensively analyzed. Coccomyxa simplex is a lichen-forming microalga whose desiccation tolerance is associated with both constitutive features and induced responses to desiccation and rehydration. Here we test the extent of transcriptional regulation in the response to a different number of desiccation/rehydration (D/R) cyles and identify genes/cellular processes possibly related with desiccation tolerance.
