ABSTRACT.
Bacterial wilt (BW) caused by Ralstonia solanacearum is responsible for substantial losses in cultivated potato (Solanum tuberosum) crops worldwide. Resistance genes have been identified in wild species; however, introduction of these through classical breeding has achieved only partial resistance, which has been linked to poor agronomic performance. The Arabidopsis thaliana (At) pattern recognition receptor elongation factor-Tu (EF-Tu) receptor (EFR) recognizes the bacterial pathogen-associated molecular pattern EF-Tu (and its derived peptide elf18) to confer anti-bacterial immunity. Previous work has shown that transfer of AtEFR into tomato confers increased resistance to R. solanacearum. Here, we evaluated whether the transgenic expression of AtEFR would similarly increase BW resistance in a commercial potato line (INIA Iporá), as well as in a breeding potato line (09509.6) in which quantitative resistance has been introgressed from the wild potato relative Solanum commersonii. Resistance to R. solanacearum was evaluated by damaged root inoculation under controlled conditions. Both INIA Iporá and 09509.6 potato lines expressing AtEFR showed greater resistance to R. solanacearum, with no detectable bacteria in tubers evaluated by multiplex-PCR and plate counting. Notably, AtEFR expression and the introgression of quantitative resistance from S. commersonii had a significant additive effect in 09509.6-AtEFR lines. These results show that the combination of heterologous expression of AtEFR with quantitative resistance introgressed from wild relatives is a promising strategy to develop BW resistance in potato.

ABSTRACT.
A hedonic model of feeder and replacement cattle prices in Uruguay was specified to include both permanent agroecological factors (soil productivity and water holding capacity [WHC]) and nonpermanent factors (season, available soil moisture, and pasture conditions) as explanatory variables. Results indicate that predominant agroecological endowments (soil characteristics, water availability, and average seasonal climatic conditions) determine geographic price patterns for cattle produced under extensive production systems. In addition, weather variability and especially extreme events have an important impact on short-run cattle markets. As pasture conditions improve or precipitation increases (e.g., both soil moisture and surface runoff), livestock prices tend to fall, ceteris paribus. A cattle price gap between different regions of Uruguay based on permanent resource endowments (e.g., soil productivity and WHC) and temporary agroecological conditions exists and is illustrated using a series of iso-price maps. The hedonic price model also included various cattle characteristics and marketing conditions as explanatory variables. Grass-fed cattle in Uruguay are not a homogeneous commodity; video auction prices incorporate information about a range of agroecological factors that influence cattle production, marketing patterns, as well as perceived and actual cattle quality and performance.
