Sentence examples for morphological metamorphosis from inspiring English sources
The term "larva" is usually defined as the stage from hatching to metamorphosis, but as mentioned for example by Hadfield (in [ 36]), this definition is more related to methods of dispersal than to changes in morphology; in most "direct-developing" gastropods, the morphological metamorphosis, with the loss of a velum or only of a prototroch, occurs before hatching from the egg capsule.
To further explore the effect of T4 on gene expression and morphological metamorphosis we conducted a principal component analysis (PCA).
Moreover, some of the genes that were differentially expressed were identified early in the larval period, well before the onset of morphological metamorphosis.
This analysis shows that global gene expression and morphological metamorphosis are strongly correlated, but there is little or no correlation between gene expression and T4 treatment.
At Day 28, axolotls reared in 50 nM T4 had fully resorbed tailfins and gills, and thus had completed morphological metamorphosis (Stage IV).
These patterns indicate that met1 genotype is associated with cis and trans transcriptional changes that commence late in the larval period, before morphological metamorphosis.
Development is direct; newly hatched individuals do not pass through morphological changes (metamorphosis) but instead are miniature replicas of their parents.
Many genes that are associated with molecular and morphological events during metamorphosis have been identified from studies of anurans, and in particular Xenopus laevis.
Consistently, we found that cyclopamine treatment had little effect on overall external morphological changes during metamorphosis but had a strong effect on the intestinal remodeling.
Interestingly, the differentiation of bacteroids is often accompanied by a morphological and cytological metamorphosis whereby the bacteroid cell becomes enlarged, its envelope fragilized and its genome amplified (polyploid) and condensed [ 6, 7].
Affinities with vertebrates are visible in the body plan organization of ascidian larvae and, despite major morphological rearrangements during metamorphosis, they are also retained in sessile adults [ 12, 13].
