Role of Jun N-terminal Kinase (JNK) signaling in the wound healing and regeneration of a Drosophila melanogaster wing imaginal disc.
The results directly show that homotypic wound healing is not a prerequisite for regenerative cell divisions, and show that JNK signaling participates in imaginal disc wound healing and is regulated by the physical dynamics of the process, as well as in recruiting cells into the Regenerative cell cycles.
The Drosophila kinesin-like protein KLP3A is required for proper behavior of male and female pronuclei at fertilization.
It is found that the KLP3A protein is located throughout the metaphase spindle during meiosis and the early embryonic mitotic divisions, but later accumulates specifically at the midzone of these same spindles during telophase.
Chromosome numbers, sex determining systems, and patterns of the C-heterochromatin distribution in 13 species of lace bugs (Heteroptera, Tingidae).
For the first time constitutive heterochromatin was localized on chromosomes in all the species studied, evidencing that a quite substantial redistribution of chromosome material within chromosomes might occur without fragmentations or fusions.

It was found that the telomere, being kinetically active during the first meiotic division, is kinetically inactive during the second division, suggesting dikinetic nature of meiotic chromosomes.
Patterns of chromosome banding in four nabid species (Heteroptera, Cimicomorpha, Nabidae) with high chromosome number karyotypes.
New information on the genome organization and new cytological markers useful for a better insight into karyotype evolution of nabid species are provided.
Achiasmatic male meiosis in Myrmedobia coleoptrata(Fn.) (Heteroptera, Microphysidae)
Mitosis and male meiosis were studied in Myrmedobia coleoptrata and spermatogonial metaphase revealed 14 chromosomes, with achiasmatic meioses and their distribution within Heteroptera.
Achiasmatic male meiosis in two species of Saldula (Saldidae, Hemiptera).
Male meiosis in two species of Saldula, S. orthothila and S. saltatoria was studied and the existence of a Y-chromosome was recorded for the first time in this primitive heteropteran genus, found to be similar to that of sex chromosomes in more advanced Heteroptera.
Holocentric chromosomes in meiosis. I. Restriction of the number of chiasmata in bivalents
The elimination of the cells carrying bivalents with more than two chiasmata creates a strong selection against the formation of more than one chiasma loops in holocentric bivalENTs.
Cytogenetics of the true bug infraorder Cimicomorpha (Hemiptera, Heteroptera): a review
A review of essential cytogenetic characters of the Cimicomorpha is presented and the chief objectives and goals of future investigations in the field are outlined.
Achiasmatic male meiosis in Cimex sp. (Heteroptera, Cimicidae)
Chromosomes and their behaviour in spermatogenesis in Cimex species from a bat species Myotis emarginatus were studied by using both a conventional staining method and sequence-specific fluorochromes CMA3 and DAPI, indicating that in heterochromatin GC-rich clusters are dispersed within AT-rich repeats.
