Acta Societatis Botanicorum Poloniae, 2015 During megasporocyte and embryo sac development in Lilium regale, characteristic changes were noted within the cytoplasm. In the course of prophase I there appear parallel systems of endoplasmic reticulum cisternae which further transform to cytoplasmic ...

Embryo sac development in Stellaria media
Acta Societatis Botanicorum Poloniae, 2014 Osmiophilic granules were observed during certain stages of intermitotic periods in one, two and four nucleate embryo sacs in Stellaria media. The granules, some inside the short ER cisternae, were mainly distributed along the walls of nucleate embryo ...

Megasporogenesis and development of the embryo sac in the Palestine variety of Trifolium alexandrinum L. [PDF]
Acta Societatis Botanicorum Poloniae, 2015 The structure and development of the embryo sac in Trifolium alexandrinum (Palestine variety), are very similar to that in Trifolium pratense. The embryo sac of Trifolium alexandrinum is monosporal, has eight nuclei and is of the Polygonum type.

Frontiers in Plant Science, 2014 The embryo sac, the female gametophyte of flowering plants, plays important roles in the pollination and fertilization process. Maize (Zea mays L.) is a model monocot, but little is known about the interactions between its embryo sac and the pollen tube.

Embryo sac development in Vanroyenella plumosa, Podostemaceae
Aquatic Botany, 2002 Species of Podostemaceae grow in rapidly flowing tropical rivers, streams and water falls, strongly attached to rock substrates via expanded, adhesive-secreting holdfasts (haptera). Vanroyenella is a monotypic genus endemic to Mexico, occurring in the northern extent of the tropical distribution of Podostemaceae in the New World. Embryo sac development

Embryo sac development in some South African Lantana species (Verbenaceae)
Bothalia: African Biodiversity & Conservation, 1984 Evidence that the South African Lantana camara L. complex only produces sexual embryo sacs is provided. It is shown that the archesporium occasionally divides mitotically and that both archesporia form tetrads.

EMBRYO SAC DEVELOPMENT 1 affects seed setting rate in rice by controlling embryo sac development
Plant Physiology, 2021 Abstract Seed setting rate is one of the critical factors that determine rice yield. Grain formation is a complex biological process, whose molecular mechanism is yet to be improved. Here we investigated the function of an OVATE family protein, Embryo Sac Development 1 (ESD1), in the regulation of seed setting rate in rice (Oryza ...
