Abstract
Leaf rust (LR) (caused by Puccinia hordei) and spot blotch (SB) (caused by Cochliobolus
sativus) are two of the main diseases of barley in Uruguay. We studied the genetics
of the resistance to both diseases present in a doubled-haploid (DH) population derived
from the cross BCD47 × Baronesse. BCD47 has low SB severity and high susceptibility to
LR, while Baronesse is susceptible to SB and has low susceptibility to LR. Both resistances
were expressed at the adult plant stage. The population was phenotyped in 9 environments
for each disease. Four QTLs were detected for SB, on chromosomes 1H, 3H, 6H and
7H. In three of them, BCD47 contributed the resistant alleles. The QTLs on chromosome
1H (located in the Bmac213-Bmag770 interval) and chromosome 3H (located in the
Bmag225-Bmag013 interval) were the most consistent across environments. Two main
QTLs were detected for LR on chromosomes 6H (Baronesse contributing the resistant
allele) and 7H (BCD47 contributing the resistant allele), coincident with SB
resistance QTLs. The QTL on chromosome 6H (linked to the SSR Bmag173) was the
most consistent across environments. |

ABSTRACT.
The indolizidine alkaloid swainsonine, found in some Astragalus and Oxytropis (i.e., locoweed) species, is a potent cellular glycosidase inhibitor that often poisons livestock. Other toxic genera such as some Ipomoea species also contain swainsonine as well as calystegines which are similar polyhydroxy alkaloids. The toxicity of calystegines is poorly characterized; however, they are also potent glycoside inhibitors capable of intestinal and cellular glycoside dysfunction. The objective of this study was to directly compare A. lentiginosus and I. carnea poisoning in goats to better characterize the role of the calystegines. Three groups of four goats each were treated with ground alfalfa (control), I. carnea or A. lentiginosus to obtain daily doses of 0.0, 1.5, and 1.5 mg swainsonine/kg bw per day, respectively, for 45 days. Animals were observed daily and weekly body weights, serum enzyme activities, and serum swainsonine concentrations were determined. At day 45 all animals were euthanized and necropsied. Goats treated with A. lentiginosus and I. carnea developed clinical disease characterized by mild intention tremors and proprioceptive deficits. Goats treated with A. lentiginosus developed clinical disease sooner and with greater consistency. No differences in body weight, serum swainsonine concentrations and serum enzyme activity were observed between goats treated with A. lentiginosus and I. carnea. Additionally, there were no differences in the microscopic and histochemical studies of the visceral and neurologic lesions observed between goats treated with A. lentiginosus and I. carnea. These findings suggest that I. carnea-induced clinical signs and lesions are due to swainsonine and that calystegines contribute little or nothing to toxicity in goats in the presence of swainsonine.
