Trichoplaxin — A new membrane-active antimicrobial peptide from placozoan cDNA [PDF]

open access: yes, 2014
A method based on the use of signal peptide sequences from antimicrobial peptide (AMP) precursors was used to mine a placozoa expressed sequence tag database and identified a potential antimicrobial peptide from Trichoplax adhaerens.

Why isn’t sex optional? Stem-cell competition, loss of regenerative capacity, and cancer in metazoan evolution

open access: yesCommunicative & Integrative Biology, 2020
Animals that can reproduce vegetatively by fission or budding and also sexually via specialized gametes are found in all five primary animal lineages (Bilateria, Cnidaria, Ctenophora, Placozoa, Porifera).

Social Feeding Behavior of Trichoplax adhaerens

open access: yesFrontiers in Ecology and Evolution, 2019
Animals have evolved different foraging strategies in which some animals forage independently and others forage in groups. The evolution of social feeding does not necessarily require cooperation, social feeding can be a beneficial individual-level ...

Expression of multiple Sox genes through embryonic development in the ctenophore Mnemiopsis leidyi is spatially restricted to zones of cell proliferation [PDF]

open access: yes, 2014
Background: The Sox genes, a family of transcription factors characterized by the presence of a high mobility group (HMG) box domain, are among the central groups of developmental regulators in the animal kingdom.

Phylogeny of phylum Porifera [PDF]

open access: yes, 2012
U znanosti postoji težnja za rješavanjem evolucijske povijesti taksonomskih skupina živih (i poznatih izumrlih) organizama. Ovim se kompleksnim zadatkom bavi filogenija.

Evo-Devo [PDF]

open access: yes, 2013
Evo-Devo je grana biologije koja uspoređuje razvojne procese različitih organizama za određivanje ancestralnog odnosa među njima i otkivanje kako su evoluirali razvojni procesi. U ovom radu usmjerila sam se na aspekt unutar područja Evo-Devo, a radi se o
