The zygote in flowering plants usually divides transversely to form a terminal cell, which gives rise to the embryo proper, and a vacuolated basal cell, which often divides rapidly to form a structure known as the suspensor. Angiosperm suspensors vary widely in size and morphology from a single cell to a massive column of several hundred cells (Maheshwari, 1950; Wardlaw, 1955; Lersten, 1983). I...

Phosphoinositides play important roles in plant growth and development. Several SAC domain phosphoinositide phosphatases have been reported to be for Here, we show functional analysis of SUPPRESSOR OF ACTIN 6 (SAC6) SAC8 Arabidopsis, a subfamily containing SAC-domain two transmembrane motifs. We isolated an Arabidopsis mutant ncp2 that lacked cotyledons seedling embryo pid, background defective...

Background: Comparative features of embryos developed under in vitro and vivo conditions are particularly important designing embryo transfer procedures that fulfil embryo-recipient synchronization requirements. Objective: To determine the degree asynchrony rabbit development between cultured embryos. Methods: A total 55 non-lactating multiparous female rabbits were used. Embryos classified as ...
