Understanding the mechanisms involved in plant development plasticity can generate significant contributions to increase crop production, mainly as climate change conditions affects crop growth worldwide. Snakin/GASA proteins are widely distributed among plant species. They are expressed in different plant organs with high tissue and temporal specificity. Interestingly, all of them maintain 12 cysteines of the C-terminus in highly conserved positions of the aminoacid sequences. Despite their common features, their functions are not completely elucidated and little is known about their mode of action. They have been involved in different aspects of plant growth and development, however, the exact role played by these proteins is still intriguing (Nahirñak et al., 2012). In order to contribute to the deepening of knowledge on Snakin/GASA family genes and their possible involvement in developmental plasticity of plants in response to environmental stress, we decide to determine the involvement of different GASA genes of Arabidopsis thaliana in plant development under optimal and sub-optimal environmental conditions. The aim of the project is to identify and understand the molecular mechanisms and developmental processes in which GASA genes are involved.
