چکیده
We present ABA, a new approach to handling preferences in a well known structured argumentation formalism, Assumption-Based Argumentation (ABA). In ABA, preference information given over assumptions is incorporated directly into the attack relation, thus resulting in attack reversal. ABA conservatively extends ABA and exhibits various desirable features regarding relationship among argumentation semantics as well as preference handling. We also introduce Weak Contraposition, a principle concerning reasoning with rules and preferences that relaxes the standard principle of contraposition, while guaranteeing additional desirable features for ABA.

Putting Down Roots: How Nitrate and Abscisic Acid Help Shape Root System Architecture.
Nitrate has profound effects on plant growth and development. Adequate nitrate levels inhibit lateral root growth, as the plant senses it has all the nitrate it needs. Conversely, a patch of nitrate in poor soil triggers the initiation or elongation of lateral roots, a remarkably plastic process that requires the interplay of nitrate sensing and auxin signaling pathways (Krouk et al., 2010). Th...
متن کاملRole of abscisic acid (ABA) and Arabidopsis thaliana ABA-insensitive loci in low water potential-induced ABA and proline accumulation.
The mechanisms by which plants respond to reduced water availability (low water potential) include both ABA-dependent and ABA-independent processes. Pro accumulation and osmotic adjustment are two important traits for which the mechanisms of regulation by low water potential, and the involvement of ABA, is not well understood. The ABA-deficient mutant, aba2-1, was used to investigate the regula...
متن کاملGenotype effects on ABA consumption and somatic embryo maturation in interior spruce (Picea glaucaxengelmanni).
Abscisic acid (ABA) plays an important role during somatic embryo development and maturation in coniferous species. The purpose of this research was to study ABA utilization by genotypes with different embryo maturation capabilities in interior spruce. Cell lines ISP11 and ISP48 were of high embryo maturation capability. By contrast, the tissue of line ISP16 contained numerous immature embryos,...
متن کاملStructural analogs of ABA reveal novel features of ABA perception and signaling in Arabidopsis.
Changes in gene expression produced by the application of (+)-abscisic acid (ABA) to Arabidopsis thaliana plants were compared with changes produced by the ABA structural analogs (-)-ABA, (+)-8'-acetylene ABA and (-)-2',3'-dihydroacetylenic abscisyl alcohol. The maximum expression of many rapidly (+)-ABA-induced genes occurred prior to peak hormone accumulation, suggesting negative feedback reg...

متن کاملGSTF1 Gene Expression Analysis in Cultivated Wheat Plants under Salinity and ABA Treatments
Most plants encounter stress such as drought and salinity that adversely affect growth, development and crop productivity. The expression of the gene glutathione-s-transferases (GST) extends throughout various protective mechanisms in plants and allows them to adapt to unfavorable environmental conditions. GSTF1 (the first phi GSTFs class) gene expression patterns in the wheat cultivars Mahuti ...
