Aflatoxins, produced by the fungus Aspergillus flavus, contaminate maize grain and threaten human food and feed safety. Plant resistance is considered the best strategy for reducing aflatoxin accumulation. Six maize germplasm lines, TZAR101–TZAR106, were released by the International Institute of Tropical Agriculture-Southern Regional Research Center (IITA-SRRC) maize breeding collaboration for...

Over the past years, two breeding lines, derived originally from outbred Wistar rats, have been established that differ markedly and consistently in their anxiety-related behaviour in the elevated plus-maze. At the age of ten weeks, rats were tested once on the elevated plus-maze and the males and females displaying the most anxious and the least anxious behaviour were sib-mated to start a new ...

LTHOUGH close inbreeding does divide a population up into lines, members A of which are in general very similar-wRIGHT claims there was never any difficulty in telling to which of his 23 lines of inbred guinea pigs any individual guinea pig belonged-it has often been observed that some characters in some lines become more variable with inbreeding. The characters for which this has been found to...

quantitative and qualitative characteristics and storability of behbahan landrace, selected population from behbahan landrace and primavera cultivar were compared for two years (2009-2010) at behbahan agriculture research station. field experiment was performed based on randomized complete block design containing four replications. seedlings were transplanted in mid-december. a split plot in ti...

FAST and SLOW selected mouse lines were bred for differences in locomotor response to low-dose ethanol. FAST mice exhibit an extreme stimulant response and SLOW mice exhibit locomotor depression at the same ethanol dose. We tested the hypothesis that gamma-aminobutyric acid (GABA) systems modulate ethanol's stimulant effects by examining convulsant responses to GABAA receptor ligands, and by as...

A pharmacokinetic dosing study with camphor was used to determine whether selection lines of high-juniper-consuming goats (HJC, n = 12) and low-juniper-consuming goats (LJC, n = 12) differed in their respective disposition kinetics. Postdosing plasma camphor concentrations were used to examine whether a timed single blood sample collected after intraruminal administration of camphor would be a ...
