Desiccation tolerance (DT) is the capacity to withstand total loss of cellular water. This property is acquired during seed filling and lost just after germination. However, in many species, a germinated seed can regain DT under adverse conditions such as osmotic stress. We discovered that the germinated seeds of the abscisic acid insensitive 5 (Mtabi5) mutant of Medicago truncatula lost their ability to re-establish DT during osmotic stress. To characterize the molecular processes that are influenced by MtABI5 during the re-establishment of DT tolerance, a transcriptome analysis was performed on the protruded radicles of germinated Mtabi5 mutants and wilt type before and after an osmotic treatment. Six-condition experiment, R108_T versus R108_P, abi5-1_T versus abi5-1_P, abi5-2_T versus abi5-2_P. Biological replicates: 9 controls (R108-T, abi5-1_T, abi5-2_T), 9 treatments (R108-P, abi5-1_P, abi5-2_P), independently grown and harvested. One replicate per array.
