Ultrastructural Changes in Cells of Pea Embryo Radicles during Germination

Radicles (1 mm long) of pea embryo axes, excised from dormant seeds and from seeds soaked for 80 min, 8, 12, and 48 hr, were fixed in glutaraldehyde and postfixed in OsO(4). The nucleus was only slightly changed by 48 hr soaking, but cytoplasmic organelles underwent developmental changes. There was proliferation of endoplasmic reticulum, the appearance of dictyosomes, and an inward migration of...

Changing desiccation tolerance of pea embryo protoplasts during germination.

Protoplasts were isolated from pea (Pisum sativum L. cv. Alaska) embryonic axes during and after germination to determine whether the loss of desiccation tolerance in the embryos also occurs in the protoplasts. At all times studied, protoplast survival decreased as water content decreased; however, the sensitivity to dehydration was less when the protoplasts were isolated from embryos that were...

Developmental and embryo axis regulation of gibberellin biosynthesis during germination and young seedling growth of pea.

The expression patterns of five genes (PsGA20ox1, PsGA20ox2, PsGA3ox1, PsGA2ox1, and PsGA2ox2) encoding five regulatory gibberellin (GA) biosynthesis enzymes (two GA 20-oxidases, a GA 3beta-hydroxylase, and two GA 2beta-hydroxylases) were examined to gain insight into how these genes coordinate GA biosynthesis during germination and early postgermination stages of the large-seeded dicotyledonou...

Ultrastructural Study of Cadmium Effects on Photoreceptors and Ganglionic Cells of Retinal Layer in Mice Embryo

Purpose: In this study, TEM was used to asses the ultra structural effects of Cd on Photoreceptor and Ganglionic cells of mouce retinal layer. Materials and Methods: 30 mice hi1Vebeen used in three groups (experimental I, II & control). On 9th day of gestation, experimental groups have received a single IP injection of Cadmium- chlorid (Cd C12) solution in saline, 3 mg/kg and 5 mg/kg respectiv...

Changes in some nitrogenous components during the germination of pea seeds.

The changes in major nitrogenous components during the germination of pea seeds have been followed. During the period of rapid axis growth, 3 to 8 days following germination, the nitrogen content of the cotyledons declines rapidly with an accompanying increase of nitrogen in the developing axis. The accumulation of alcohol soluble nitrogen, primarily amino nitrogen, in the cotyledons and axis d...
