Physiological characterization of stolon regression in a colonial hydroid.
As with many colonial animals, hydractiniid hydroids display a range of morphological variation. Sheet-like forms exhibit feeding polyps close together with short connecting stolons, whereas runner-like forms have more distant polyps and longer connecting stolons. These morphological patterns are thought to derive from rates of stolon growth and polyp formation. Here, stolon regression is ident...
متن کاملCauses and consequences of stolon regression in a colonial hydroid.
A cnidarian colony can be idealized as a group of feeding polyps connected by tube-like stolons. Morphological variation ranges from runner-like forms with sparse polyp and stolon development to sheet-like forms with dense polyp and stolon development. These forms have typically been considered in a foraging context, consistent with a focus on rates of polyp development relative to stolon elong...
متن کاملStructure and signaling at hydroid polyp-stolon junctions, revisited
The gastrovascular system of colonial hydroids is central to homeostasis, yet its functional biology remains poorly understood. A probe (2',7'-dichlorodihydrofluorescein diacetate) for reactive oxygen species (ROS) identified fluorescent objects at polyp-stolon junctions that emit high levels of ROS. A nuclear probe (Hoechst 33342) does not co-localize with these objects, while a mitochondrial ...
متن کاملIntercellular Connections in the Outgrowing Stolon of Cordylophora
Outgrowth of the stolon in the hydroid Cordylophora has been studied at the cellular level. Staining experiments and histological examination indicate that the generative region of the stolon is at its base where interstitial cells are prominent. Cells in the ectoderm at the stolon tip appear to be actively synthesizing new perisarc as the tip advances over the substrate, rather than involved i...
متن کاملTranscriptome Analysis of Differentially Expressed Genes Provides Insight into Stolon Formation in Tulipa edulis
Tulipa edulis (Miq.) Baker is an important medicinal plant with a variety of anti-cancer properties. The stolon is one of the main asexual reproductive organs of T. edulis and possesses a unique morphology. To explore the molecular mechanism of stolon formation, we performed an RNA-seq analysis of the transcriptomes of stolons at three developmental stages. In the present study, 15.49 Gb of raw...
