(1–4 days, depending on the species and temperature). The pluteus larva is bilaterally symmetrical and bears almost no resemblance to an adult sea urchin. After a period of feeding and growth that can last several weeks, the rudiment of the adult body forms within the larva (Smith et al...
Since this meeting is dedicated to the memory of Alberto Monroy I will touch on a few problems which represent some of the main fields of the research which are being carried out in the Department of Cellular and Developmental Biology of Palermo, which bears his name, problems which are ...
the sea urchin (echinoid) larval skeleton has also become a paradigm for understanding the mechanistic basis for development, and the genetic regulatory networks operating in larval echinoid skeletal development are exceptionally well-understood [7,8]. While there is a breadth of knowledge concerning t...
In yeast, the N terminal end of eRF3 (Sup35) bears a prion forming domain (Inge-Vechtomov et al., 2003). In mammals, two genes encode for eRF3 proteins, GSPT1 and GSPT2 that differ in their N-terminal domains (Hoshino et al., 1998), which have no homology with yeast N-domain...

optical fibers and optical phase modulation for improved imaging quality without using an objective lens to receive light from a target. Among its applications is an endoscope that bears no lens at the distal end, which affords miniaturization and bendability, and that has adjustable focal distance....
Over the course of the second cell cycle (two-cell stage), the activity undergoes a 2-fold oscillation that bears the same temporal relationship to mitosis as the previous fluctuation. 展开 关键词: Cell Biology Dielectric Breakdown Mitosis ...
Metamorphosis/development of E. cordatum , thus, is closer to that of clypeasteroids, since the rudiment of the latter already bears juvenile definitive appendages, when everted during metamorphsis. 展开 关键词: Echinocardium n cordatum Development Larval growth Metamorphosis Postlarva ...
Our data demonstrate that He185/333 bears the same substantial characteristics as their S. purpuratus homologues. However, we also identify several unique characteristics of He185/333 (such as novel element patterns, sequence repeats, distribution of positively-selected codons and introns), suggesting ...
The full cDNA sequence for one of these, βG, bears a 59% similarity to Drosophila βPS and a 58% similarity to vertebrate integrins. βG closely resembles the β1 subunit of vertebrates, particularly in the cytoplasmic domain where amino acids of the human β1 subunit implicated in cell ...
