Suspensor length determines developmental progression of the embryo in Arabidopsis.
The first structure that differentiates during plant embryogenesis is the extra-embryonic suspensor that positions the embryo in the lumen of the seed. A central role in nutrient transport has been ascribed to the suspensor in species with prominent suspensor structures. Little is known, however, about what impact the size of the rather simple Arabidopsis (Arabidopsis thaliana) suspensor has on...

متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
The suspensor: not just suspending the embryo.
The suspensor is a terminally differentiated embryonic region that connects the embryo to surrounding tissues during early seed development. Most seed-bearing plant embryos contain suspensor regions, which occur in a wide variety of sizes and shapes, and suspensor-like structures are present in the embryos of some lower land plants. Recent technological advances, including novel genomics approa...
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) ...
