Regional localization of suspensor mRNAs during early embryo development.
We investigated gene activity within the giant embryos of the scarlet runner bean (Phaseolus coccineus) to gain understanding of the processes by which the apical and basal cells become specified to follow different developmental pathways after division of the zygote. We identified two mRNAs, designated G564 and C541, that accumulate specifically within the suspensor of globular-stage embryos. ...
متن کاملThe Role of Glycoconjugates in Development of Floor Plate During Early Morphogenesis in Mouse Embryo
The floor plate is a small group of cells located at the ventral midline of neural tube. During early neurogenesis the floor plate plays critical role (s) in differentiation of ventral portion of neural tube.The purpose of this study was to determine the distribution of glycoconjugates in floor plate as well as underlying mesoderm (notochord) and their inductive activities in mouse embryos.Form...
متن کاملGibberellins in Embryo-Suspensor of Phaseolus coccineus Seeds at the Heart Stage of Embryo Development.
Gibberellins (GAs) in suspensors and embryos of Phaseolus coccineus seeds at the heart stage of embryo development were analyzed by combined gas chromatography-mass spectrometry (GC-MS). From the suspensor four C(19)-GAs, GA(1), GA(4), GA(5), GA(6), and one C(20) GA, GA(44), were identified. From the embryo, five C(19)-GAs GA(1), GA(4), GA(5), GA(6), GA(60) and two C(20) GAs, GA(19) and GA(44) ...
متن کاملGibberellins in Embryo - Suspensor of Phaseolus coccineus Seeds at the Heart Stage of Embryo Development 1
Gibberellins (GAs) in suspensors and embryos of Phaseolus coccineus seeds at the heart stage of embryo development were analyzed by combined gas chromatography-mass spectrometry (GC-MS). From the suspensor four C,9-GAs, GA1, GA4, GA5, GA6, and one C2o GA, GA44, were identified. From the embryo, five C1gGAs GA,, GA4, GAs, GAs, GAo0 and two C20 GAs, GA1,9 and GA4 were identified. The data, in rel...
متن کاملCell Lineage of the Ilyanassa Embryo: Evolutionary Acceleration of Regional Differentiation during Early Development
Cell lineage studies in mollusk embryos have documented numerous variations on the lophotrochozoan theme of spiral cleavage. In the experimentally tractable embryo of the mud snail Ilyanassa, cell lineage has previously been described only up to the 29-cell stage. Here I provide a chronology of cell divisions in Ilyanassa to the stage of 84 cells (about 16 hours after first cleavage at 23 degre...
