    Notes: Summary The relationship between heterozygosity and the expression of heterosis at two different nutrition levels was investigated using Drosophila melanogaster. Average daily egg production and egg hatchability were measured in two parental strains and in F1, F2 and reciprocal backcross generations. Heterosis was more pronounced in the poor nutritional conditions. Two electrophoretic markers used to estimate the level of heterozygosity in F2 and backcrosses revealed an excess of heterozygous genotypes. Quantitative genetic effects (an additive line effect and individual and maternal heterosis) were estimated for both traits in the two environments. Although this model gave a reasonable fit in most cases, some epistatic interaction would have to be invoked in order to explain fully the results.

    Notes: Abstract A suppressor of resistance to powdery mildew conferred by Pm8 showed complete association with the presence of a storage-protein marker resolved by electrophoresis on SDS-PAGE gels. This marker was identified as the product of the gliadin allele Gli-A1a. The mildew-response phenotypes of wheats possessing the 1BL.1RS translocation were completely predictable from electrophoretograms. The suppressor, designated SuPm8, was located on chromosome 1AS. It was specific in its suppression of Pm8, and did not affect the rye-derived resistance phenotypes of wheat lines with Pm17, also located in 1RS, or of lines with Pm7.

    Notes: Summary Nerve fibres and perikarya containing LH-RH-like material were identified immunohistochemically in the diencephalon of the domestic hen using the peroxidase-anti-peroxidase technique. Perikarya were thinly scattered in bilateral bands close to the third ventricle extending from the nucleus praeopticus paraventricularis magnocellularis, passing in front of the anterior commissure into the septal area. In this latter area, the perikarya tended to spread out laterally. A few perikarya were seen in the anterior portion of the nucleus paraventricularis magnocellularis but were not found in the infundibular nuclear complex. Fibre tracts were seen running dorso-ventrally in the preoptic area apparently associated with the lamina terminalis. Fibres, possibly nerve terminals, were found in the lamina terminalis and in the external layers of the anterior and posterior divisions of the median eminence. A large number of fibres was seen distributed throughout the infundibular nuclear complex; scattered fibres were found close to the third ventricle in the anterior hypothalamus. Extrahypothalamic fibres were also observed to project from the septal area into other parts of the telencephalon.

    Notes: Summary Cell nuclei containing progesterone receptor were identified immunohistochemically in the hypothalamus and forebrain of the domestic hen using an antiserum to the steroid binding “B” subunit (110 kDa) of chicken oviduct progesterone receptor and the avidin-biotin complex procedure. Cell nuclei containing progesterone receptor were widely distributed in the anterior, medial and basal hypothalamus with the highest density occurring in the lamina terminalis and the preoptic area. Abundant, though less intensely reacting progesterone receptor was present in cell nuclei in the tuberal infundibular area and in the internal zone of the median eminence. A large group of cell nuclei containing progesterone receptor occurred in the dorsal anterior hypothalamus between the anterior commissure and the lateral ventricle. This group of nuclei extended anteriorly into the telencephalon. A small number of cell nuclei containing progesterone receptor was also found in the ventral telencephalon in the region of the nucleus accumbens.
