Molecular Aspects of Regeneration Mechanisms in Holothurians

open access: yesGenes, 2021
Holothurians, or sea cucumbers, belong to the phylum Echinodermata. They show good regenerative abilities. The present review provides an analysis of available data on the molecular aspects of regeneration mechanisms in holothurians. The genes and signaling pathways activated during the asexual reproduction and the formation of the anterior and ...

Underwater Holothurian Target-Detection Algorithm Based on Improved CenterNet and Scene Feature Fusion [PDF]

open access: yesSensors, 2022
Aiming at the common problems, such as noise pollution, low contrast, and color distortion in underwater images, and the characteristics of holothurian recognition, such as morphological ambiguity, high similarity with the background, and coexistence of ...

The trophic biology of the holothurian Molpadia musculus: implications for organic matter cycling and ecosystem functioning in a deep submarine canyon [PDF]

open access: yesBiogeosciences, 2010
Megafaunal organisms play a key role in ecosystem functioning in the deep-sea through bioturbation, bioirrigation and organic matter cycling. At 3500 m water depth in the Nazaré Canyon, NE Atlantic, very high abundances of the infaunal holothurian ...

Toxic properties of holothurian’s triterpene glycosides

open access: yesВестник войск РХБ защиты, 2023
Holothurians (or sea cucumbers) are echinoderms and are found in all areas of the world oceans. These animals produce special low-molecular metabolites - triterpene glycosides, which are a means of chemical protection of holothurians from predators.

Origin of the holothurians (Echinodermata) derived by constructional morphology [PDF]

open access: yesFossil Record, 2002
According to a recent hypothesis, the holothurians originated by a process of extreme paedomorphism as "giant larvae", with "de novo" developed radial systems.

Highly rearranged gene orders and rapid evolutionary rates in the mitochondrial genomes of Apodida (Echinodermata: Holothuroidea)

open access: yesFrontiers in Marine Science, 2023
Mitochondrial genome (mitogenome) is a frequently-used tool for phylogenetic and evolutionary studies among metazoans, however, it was still poorly represented in some invertebrate groups, including holothurians. Apodida is one of the most ancient orders

Current Progress in Lipidomics of Marine Invertebrates

open access: yesMarine Drugs, 2021
Marine invertebrates are a paraphyletic group that comprises more than 90% of all marine animal species. Lipids form the structural basis of cell membranes, are utilized as an energy reserve by all marine invertebrates, and are, therefore, considered ...
