Abstract Background Animals with a spiral cleavage program, such as mollusks and annelids, make up the majority of superphylum Lophotrochozoa. The great diversity larval adult body plans in this group emerges from highly conserved developmental program. 4d micromere is one most aspects spiralian development. Unlike preceding pattern divisions, cleavages within teloblastic sublineages are bilateral, representing critical transition towards constructing bilaterian plan. These cells give rise...
Having conquered water surfaces worldwide, the semi-aquatic bugs occupy ponds, streams, lakes, mangroves, and even open oceans. The diversity of this group has inspired a range scientific studies from ecology evolution to developmental genetics hydrodynamics fluid locomotion. However, lack representative strider genome hinders our ability more thoroughly investigate molecular mechanisms underlying processes adaptation diversification within group. Here we report sequencing manual annotation...
ABSTRACT Over the course of hundreds millions years, biomineralization has evolved independently many times across all kingdoms life. Among animals, phylum Mollusca displays a remarkable diversity in biomineral structures, particularly molluscan shell, which varies greatly shape, size, pigmentation, and patterning. Shell matrix proteins (SMPs) are key components these shells, thought to drive precipitation calcium carbonate minerals influence shell morphology. However, this...
Adelphophagy occurs when encapsulated embryos complete development by feeding on their developing siblings, which are known as nutritive embryos. Nutritive found in a variety of animal groups, and especially common some groups marine invertebrates. Although they have evolved numerous times independently the calyptraeid gastropods, adelphophagic with has not been described detail. Using light microscopy time-lapse imaging laboratory-reared embryos, we describe Crepidula navicella, direct...
Abstract In marine invertebrates, polymorphism and polyphenism in mode of development are known as “poecilogony.” Understanding the environmental correlates poecilogony developmental mechanisms that produce it could contribute to a better understanding evolutionary transitions development. However, is rare with only ten recognized, well‐documented cases. Five examples occur sacoglossan gastropods, five spionid polychaetes. Here, we document eleventh case, first caenogastropod mollusc....
ABSTRACT Alternative phenotypes are discrete phenotypic differences that develop in response to both genetic and environmental cues. Nutritive embryos, which arrest their development serve as nutrition for viable siblings, an example of alternative developmental phenotype found many animal groups. Females the marine snail, Crepidula navicella , produce broods consist mainly nutritive embryos a small number embryos. In order better understand mechanisms lead this species, we compared...
This paper introduces the black-footed slipper snail, Crepidula atrasolea, as a new model for biological studies in Spiralia. C. atrasolea is calyptraeid gastropod, and congener of Atlantic fornicata. Like fornicata, shares sedentary, filter-feeding, protandrous lifestyle, but preferable developmental because its short generation time, year-round reproduction, direct development. In our lab, individuals go from egg to reproductive females under six months, compared an estimated 1-2 years...
One hundred years ago, marine organisms were the dominant systems for study of developmental biology. The challenges in rearing these outside a setting ultimately contributed to shift towards work on smaller number so-called model systems. Those animals are typically non-marine with advantages afforded by short life cycles, high fecundity, and relative ease laboratory culture. However, full understanding biodiversity, evolution, anthropogenic effects biological requires broader survey...
Sexual systems vary greatly across molluscs. This diversity includes simultaneous hermaphroditism, with both sexes functional at the same time. Most nudibranch molluscs are thought to be hermaphrodites, but detailed studies of reproductive development and timing remain rare as most species cannot cultured in lab. The aeolid nudibranch, Berghia stephanieae, is one such that can through multiple generations on benchtop. We studied B. stephanieae establish when animals first exchange sperm how...
Abstract The semi-aquatic bugs conquered water surfaces worldwide and occupy ponds, streams, lakes, mangroves, even open oceans. As such, they inspired a range of scientific studies from ecology evolution to developmental genetics hydrodynamics fluid locomotion. However, the lack representative strider genome hinders thorough investigations mechanisms underlying processes adaptation diversification in this group. Here we report sequencing manual annotation Gerris buenoi (G. buenoi) genome,...
ABSTRACT Investigation of alternative phenotypes, different morphologies produced by a single genome, has contributed novel insights into development and evolution. Yet, the mechanisms underlying developmental switch points between phenotypes remain poorly understood. The calyptraeid snails Crepidula navicella Calyptraea lichen produce two phenotypes: viable nutritive embryos, where embryos arrest their after gastrulation are ingested siblings as form intracapsular nutrition. Here, we...
What is the future of evolutionary developmental biology? This question and more were discussed at inaugural meeting for Pan American Society Evolutionary Developmental Biology, held August 5-9, 2015, in Berkeley, California, USA. More than 300 participants attended first new society, representing current diversity Evo-Devo. Speakers came from throughout Americas, presenting work using an impressive range study systems, techniques, approaches. Current research draws themes including role...
Mode of development (MOD) is a key feature that influences the rate and direction evolution marine invertebrates. Although many groups include species with different MODs, evolutionary loss feeding larvae thought to be irreversible, as complex structures used for larval swimming are lost, reduced, or modified in lacking larvae. This view largely based on observations echinoderms. Phylogenetic analysis suggests have been re-gained at least one calyptraeid gastropod. Further, its sister has...
We present the complete genome sequences of seven species sea slugs. Illumina sequencing was performed on tissue from wild-collected museum specimens. The reads were assembled using a de novo method followed by finishing step. raw and data are publicly available via Genbank.
