Molecular systematics and evolution of the "Apollo" butterflies of the genus Parnassius (Lepidoptera: Papilionidae) based on mitochondrial DNA sequence data.

Sequences of 777 bp of mtDNA-ND5 locus were determined in order to shed light on the molecular systematics and evolution of the "Apollo" butterflies. Examined were nearly all of about 50 species of the genus Parnassius, together with seven species of the allied genera in the subfamily Parnassiinae (Papilionidae). The NJ and the MP phylogenetic trees show that the "Apollos" constitute a monophyl...

Interspecific Hybrids

The regulation of gene expression is essential for organismal form, function, and fitness. Complex organismal development from zygote to adult requires finely tuned expression of genes in space, time, and abundance. Proper expression of genes is also required for most other aspects of physiology and function. Even minor changes in gene expression have the potential to significantly impact pheno...

Studies of Interspecific (Rat x Mouse) Somatic Hybrids. II. Lactate Dehydrogenase and beta-GLUCURONIDASE.

N the first paper of this series (WEISS and EPHRUSSI 1966), we described the I isolation of several different rat x mouse somatic hybrids and some of their properties. Study of their karyotypes showed that, although they lose some chromosomes in the course of successive generations, the hybrid cells retain major portions of both “parental” genomes over prolonged periods of time. The purpose of ...

Marine Puddling in Papilio Polytes (lepidoptera: Papilionidae)

Smedly & Eisner (1995, 1996) stressed the difficulties that terrestrial herbivores, including Lepidoptera, suffer in order to fulfill their need for sodium, an essential ion plentiful in the seas, but in short supply in plants. Adult Lepidoptera drink from puddles, edges of streams, carrion, and excreta from which they obtain sodium and proteins (Beck et al. 1999). Puddling behavior is typicall...

Genetic recombination in Sorghum bicolor x S. macrospermum interspecific hybrids.

Sorghum has been improved by public and private breeding programs utilizing germplasm mostly from within the species Sorghum bicolor. Until recently, cross-incompatibilities have prevented hybridization of S. bicolor with most other species within the genus Sorghum. Utilizing germplasm homozygous for the iap allele, hybrids were readily produced between S. bicolor (2n = 20; AAB1B1) and S. macro...
