Data Management Plan
<p>Phosphorus (P) is part of essential molecules for life, such as ATP, RNA and DNA molecules, and membrane lipids, among others, without which plants cannot survive. Phosphate rocks used to produce fertilizers are finite and the fact that P in the soil is frequently poorly available to plants makes it necessary to maximize the efficiency of P use by plants. More than 80% of terrestrial plant species can establish mutualistic symbiosis with arbuscular mycorrhizal (AM) fungi, including tree species as those in the eucalypt group. The establishment of AM symbiosis is highly coordinated and regulated by fungal and plant partners, with signaling molecules being exchanged. DELLA proteins are positive regulators of the development of arbuscules, considered the symbiotic-interface structure, and form complexes with regulatory proteins of the AM symbiosis signaling pathway to promote the expression of genes involved in the establishment of the fungus within the root. Gibberellins (GA) play an important role in a variety of key plant developmental processes and DELLA are central elements in the GA signal transduction pathway. P-starvation in plants causes a reduction in bioactive levels of GA and accumulation of DELLA proteins contributing to certain aspects of the P starvation response (PSR) in roots, namely, the suppression of primary root growth and the promotion of root hairs formation. In order to understand how P starvation affects plants that respond differentially to this stress, the present proposal aims to study the signaling network controlled by DELLA in two eucalyptus species colonized by mycorrhizal in response to P and verify if species differing in their susceptibility to being colonized by AM fungi have distinct signaling networks and the related physiological and molecular responses to endogenous phosphate interaction with phytohormones and DELLA proteins.</p>
