The least fragmentation was found in the embryos of dry quiescent seeds, whereas the induction of growth and development was accompanied by increase in HMW-DNA fragmentation.
In A. nidulans, the regulator of G-protein signaling flbA is required for asexual sporulation [ 45], and the Zn II 2Cys6 transcription factor encoded by nosA that is required for the induction of sexual development is also transcriptionally upregulated during asexual development [ 46].
Our data provide an unprecedented view of transcriptional changes in Anabaena filaments during the induction of heterocyst development and transition to diazotrophic growth.
During growth tumours depend on a further induction of vascular development for adequate oxygen and nutrient supply.
As previously reported, R. centenum undergoes induction of cyst development when shifted from a complex nutrient rich growth medium (CENS) to a nutrient poor defined medium that uses butyrate as a sole carbon source (CENBA) [ 16].
Production of cGMP, and subsequent induction of cyst development, is regulated by the binding of cGMP to the CRP homolog CgrA, which initiates the encystment development cascade [ 8, 10].
These results suggest that skewed nymph production in these termites is controlled via nepotistic regulation of nymphal development by reproductives, in which some offspring parthenogenetically produced by a founding female are released from the induction of worker development.
Induction of follicular development did not affect glomerular polymorphonuclear leukocyte number after endotoxin infusion but significantly decreased the number of monocytes in the glomeruli at both 4 hours and 3 days after endotoxin infusion.
In Xenopus and zebrafish, induction of pancreatic development is inhibited following treatment of early, pre-pancreatic embryos, with the RA-antagonist BMS493, and embryos treated with exogenous RA prior to the initiation of the pancreatic development show ectopic expression of pancreatic markers such as insulin [28] [31].
The nitrogen step-down produces relatively synchronous induction of heterocyst development.
