Throughout evolution, plants have evolved sophisticated adaptive responses that allow them to grow with a limited supply of phos-phate, the preferential form in which the essential macronutrient phosphorus is absorbed by plants. most of these responses are aimed to increase phosphate availability and acquisition through the roots, to optimize its usage in metabolic processes, and to protect plants from the deleterious effects of phosphate deficiency stress. Regulation of these adaptive responses requires fine percep- tion of the external and internal phosphate levels, and a complex signal transduction pathway that integrates information on the phosphate status at the whole-plant scale. The molecular mecha-nisms that participate in phosphate homeostasis include transcriptional control of gene expression, RNA silencing mediated by microRNAs, regulatory non-coding RNAs of miRNA activity, phosphate transporter trafficking, and post-translational modification of proteins, such as phosphorylation, sumoylation and ubiquitination. Such a varied regulatory repertoire reflects the complexity intrinsic to phosphate surveying and signaling pathways. Here, we describe these regulatory mechanisms, emphasizing the increasing importance of ubiquitination in the control of phosphate starvation responses.

Dempster-Shafer Theory (DST) and the analytic Hierarchy Process (AHP) are integrated in order to elicit preference information from experts regarding decision makers (Dms) involved in a regulatory conflict. more precisely, DST is used for combining expert knowledge regarding preferences of a specific Dm (the regulatory body), and AHP is employed for ranking feasible states in the conflict for this same Dm. In order to illustrate how this preference elicitation proposal can be conveniently implemented in practice within the Graph model for Conflict Resolution (GmCR), it is applied to a real construction dispute located in the city of Ipojuca, Brazil. The conflict is modeled with three Dms: support, opposition, and the regulatory body. Results show that the new preference methodology possesses many inherent advantages including high flexibility the ability to capture uncertainty or even ignorance about preferences, the possibility of combining expert knowledge with respect to missing preferences, and a substantial reduction in the number of pairwise comparisons of states required to express preference information.
