1141por O’Keefe, David D, Thomas, Sean R, Bolin, Kelsey, Griggs, Ellen, Edgar, Bruce A, Buttitta, Laura A“…To identify genetic mechanisms that control epithelial differentiation, we analyzed the temporal patterns of gene expression during metamorphosis of the Drosophila wing. RESULTS: We found that a striking number of genes, approximately 50% of the Drosophila transcriptome, exhibited changes in expression during a time course of wing development. …”

1142“…Contrary to previous studies, we found that Xenopus laevis tadpoles raised in normoxic water without access to air can routinely complete metamorphosis with lungs that are either severely stunted and uninflated or absent altogether. …”

The DNA binding domains (DBDs) of the Usp and EcR play an important role in their DNA-dependent heterodimerization. …”

1145por Singh, Priyanka, Jayaramaiah, Ramesha H., Sarate, Priya, Thulasiram, Hirekodathakallu V., Kulkarni, Mahesh J., Giri, Ashok P.“…Digestive enzymes of H. armigera - namely, amylase, protease and lipase- showed variable patterns after feeding on O. kilimandscharicum, which implies striving of the larvae to attain required nutrition for growth, development and metamorphosis. Evidently, selected metabolites from O. kilimandscharicum possess significant insecticidal activity.…”

1148por Olori, Jennifer C.“…The phylogenetic position and developmental patterns of M. pelikani and H. longicostatum are congruent with the hypothesis that early tetrapods lacked metamorphosis ancestrally and that stem-amniotes exhibited derived features of development, such as rapid and complete ossification of the skeleton, potentially prior to the evolution of the amniotic egg.…”

However, female adults oviposited non-diapause eggs despite diapause-inducing temperature and photoperiod conditions. …”

1156por von Döhren, Jörn“…With respect to the nervous system, the trochophora larva displays a set of stereotypic features, including an apical organ and trochal neurites, both of which are lost at the onset of metamorphosis. In the investigated larvae of Nemertea, the nervous system is somewhat divergent from the postulated hypothetical trochophore-like pattern. …”

To study the molecular driving force behind metamorphic development in larvae of P. fucata, transcriptomes of five larval stages (trochophore, D-shape, umbonal, eyespots, and spats) were sequenced using an Illumina HiSeq™ 2000 system and assembled and characterized with the transcripts of six tissues. …”
