Differential gene expression profile between two sunflower inbred lines with different ability to tolerate water stress

This study characterizes and compares the gene expression profiles between aerial part and roots of two sunflower inbred lines with contrasting response to water stress: B59 (sensitive) and B71 (tolerant) under non-stress and water stress mimicked by mannitol application. The results allowed us to evaluate the response of the primary and secondary metabolism as studies of the hormonal pathways of jasmonic, salicylic and abscisic acid such as gibberellins and auxins among others.
