The early embryo of the cockroach Blattella germanica exhibits high E93 expression. In general, triggers adult morphogenesis during postembryonic development. Here we show that is also crucial in embryogenesis cockroach, as a significant number E93-depleted embryos are unable to develop germ band under maternal RNAi treatment targeting . Moreover, transcriptomic analysis indicates depletion results important gene expression changes embryo, and many differentially expressed genes involved...
The influence of DNA methylation on gene behavior and its consequent phenotypic effects appear to be very important, but the details are not well understood. Insects offer a diversity modes, making them an excellent lineage for comparative analyses. However, functional studies have tended focus quite specialized holometabolan species, such as wasps, bees, beetles, flies. Here, we studied in hemimetabolan insect Blattella germanica. In this cockroach, involved methylation, methyltransferase 1...
Significance Mayflies are the only extant insects that molt after having formed wings, in a stage called subimago. Numerous authors have wondered whether this is nymph, an adult, or kind of intermediate. Another question why mayflies subimago stage, when molting wing risky. Working with Cloeon dipterum , we found metamorphosis regulated as neopteran and it determined prior to formation Thus, should be considered instar adult stage. We also forelegs grow dramatically between last nymphal...
In hemimetabolan insects, the transcription factor Broad complex (Br-C) promotes wing growth and development during nymphal period. We wondered whether Br-C could trigger initiation of development, using cockroach Blattella germanica as a model. show that first instar nymphs have their unique identity these three thoracic segments specified. During embryogenesis, expression some wing-related genes two matching waves. The takes place before formation germ band, which might be involved in...

Present-day pterygote insects have two pairs of wings, one in the mesothorax (T2), other metathorax (T3), and both diverged structure function different groups. Studies endopterygote paraneopteran species shown that gene Ultrabithorax ( Ubx ) specifies identity wing T3, whereas apterous ap significantly contributes to forming modified T2 wings. We wondered whether these mechanisms operate lineage polyneopterans. To explore this possibility, we used cockroach Blattella germanica (Polyneoptera...

Abstract In the Endopterygote Drosophila melanogaster , Zelda is a key activator of zygotic genome during maternal-to-zygotic transition (MZT). binds cis -regulatory elements (TAGteam heptamers), and makes chromatin accessible for gene transcription. Recently, has been studied in two other Endopterygotes: Apis mellifera Tribolium castaneum Paraneopteran Rhodnius prolixus . We have cockroach Blattella germanica hemimetabolan, short germ-band, Polyneopteran species. protein B. complete set...
ABSTRACT In the Paleozoic era, more than 400 million years ago, insects continued molting after forming functional wings. Today, however, all flying stop metamorphosis when they become fully winged. The only exception is mayflies (Ephemeroptera), which molt in subimago, a intermediate stage between nymph and adult. However, identity homology of subimago remains underexplored. Debate regarding whether this represents modified nymph, an adult, or pupa like that butterflies. Another relevant...
In hemimetabolan insects, the transcription factor Broad complex (Br-C) promotes wing growth and development during nymphal period. We wondered whether Br-C could trigger initiation of development, using cockroach Blattella germanica as a model. show that first instar nymphs already have their unique identity three thoracic segments specified. During embryogenesis, expression some wing-related genes two matching waves. The wave takes place before formation germ band, which might be involved...
ABSTRACT The early embryo of the cockroach Blattella germanica exhibits high E93 expression. In general, triggers adult morphogenesis during postembryonic development, but in is also crucial embryogenesis. Moreover, embryonic levels expression are hemimetabolan insects, while holometabolans they very low. They low Thysanoptera and Hemiptera Sternorrhyncha with quiescent stages, as well Odonata, nymph which different from adult. ametabolans, such Zygentoma Thermobia domestica, embryo, whereas...
