Abstract Development of Brassica napus L. cv Tower embryos of different ages cultured in
vitro with and without abscisic acid (ABA) was compared with normal development in situ to …

Abstract Development depends on the precise control of gene expression in time and space.
A critical step towards understanding the global gene regulatory networks underlying …

The sea urchin egg is a quiescent cell… until fertilization, when the egg is activated. The
classic respiratory burst at fertilization is the result of prodigious hydrogen peroxide …

Identifying cell states during development from their mRNA profiles provides insight into their
gene regulatory network. Here, we leverage the sea urchin embryo for its well-established …

The hatching enzyme is a developmentally regulated protease secreted at the blastula stage
by the sea urchin embryo to digest its protective envelope. A nearly full‐length cDNA clone …

This book should be regarded as the continuation to my previous book Developmental
Biology of the Sea Urchin Embryo, edited by the Academic Press in 1973, rather than as a …

Two distinct modes of germ line determination are used throughout the animal kingdom:
conditional—an inductive mechanism, and autonomous—an inheritance of maternal factors …

While the nematode Caenorhabditis elegans is more primitive than most egg-laying
organisms, it's vitellogenins, or yolk protein precursors, appear to be more complex. C …

By the early years of this century, experimental embryologists had demonstrated that the
cytoplasm of the egg contains informational materials that are not always evenly distributed …

We have begun the molecular characterization of genes encoding napin, the 1.7 S embryo-
specific storage protein of Brassica napus. Genomic Southern blot analysis indicates that …
