Mosaicism in Habrobracon juglandis associated with the ebony locus.
MONG species of insects that have been used for genetic studies, there Aoccasionally appear adults which are composed of two or more different genomes. In Drosophila melanogaster, where most of these mosaics were of the gynandromorph type, it has been shown that elimination of an X chromosome during early cleavage was involved (MORGAN and BRIDGES 1919; PATTERSON 1931). In a few instances, ferti...
متن کامل[Pleiotropism of wh and el locus in Habrobracon juglandis].
The two autonomously manifesting mutations, eyeless (el) and white eyes (wh), of Habrobracon juglandis were compared phenotypically with the wild-type. Eyeless reduces the compound eyes in size. The penetrance is 100%, while expressivity ranges from point-shaped ommochrome crumbs over individual facets to a small eye with abundant facets. There is no correlation between the sizes of left and ri...
متن کاملEvidence for post-cleavage fertilization among mosaics in Habrobracon juglandis.
Habrobracon females homozygous for the mutant ebony produce about 5% mosaic progeny among fertilized eggs. The present experiment demonstrates by means of a test-cross method that in the production of these mosaics only one pronucleus is involved, and that this nucleus cleaves before union of one of its daughter nuclei with the sperm nucleus.
متن کاملPierre H.A. Jolivet, the spiritus rector of leaf beetle research, with a list of his publications
Since more than half a century, Pierre Hippolyte Auguste Jolivet has been the inspiring head of the community of leaf beetle researchers (Fig. 1). He promoted research on Chrysomelidae not only by his nearly 500 publications (see list below), but even more so by his personal input to the international and European symposia on leaf beetles, and especially by the six volumes he co-edited (nos. 27...
متن کاملWalnut Blight: Genetic Variation in English Walnut in Response to Inoculation with Xanthomonas Campestris Pv. Juglandis
This was the second year of a study which evaluated the genetic variation among English walnut germplasm in response to infection by Xanthomonas campestris pv. juqlandis (Xcj), the bacterium which causes the disease walnut blight. Immature leaves and nuts of 10 walnut accessions representing the breadth of currently available germplasm were inoculated. Leaves were scored for disease severity at...
