Ethylene Promotes Elongation Growth and Auxin Promotes Radial Growth in Ranunculus sceleratus Petioles.
Submergence induces elongation in the petioles of Ranunculus sceleratus L., after a rise in endogenous ethylene levels in the tissue. Petioles of isolated leaves also elongate 100% in 24 hours when treated with ethylene gas, without a change in the radius. Application of silver thiosulfate, aminoethoxyvinylglycine (AVG), abscisic acid (ABA), or methyl jasmonate inhibits this elongation response...
متن کاملHigh temperature promotes auxin-mediated hypocotyl elongation in Arabidopsis.
Physiological studies with excised stem segments have implicated the plant hormone indole-3-acetic acid (IAA or auxin) in the regulation of cell elongation. Supporting evidence from intact plants has been somewhat more difficult to obtain, however. Here, we report the identification and characterization of an auxin-mediated cell elongation growth response in Arabidopsis thaliana. When grown in ...
متن کاملRoyal Jelly Promotes Ovarian Follicles Growth and Increases Steroid Hormones in Immature Rats
Objective Royal jelly (RJ) is a complementary diet widely used by traditional healers for the treatment of infertility. The aim of present study was to evaluate the effect of RJ on some reproductive parameters in immature female rats. MaterialsAndMethods In this experimental study, thirty two immature female rats (30-35gr) were divided into four groups (n=8 /group). Control group received 0.5 m...
متن کاملThe roles of ethylene, auxin, abscisic acid, and gibberellin in the hyponastic growth of submerged Rumex palustris petioles.
Rumex palustris responds to complete submergence with upward movement of the younger petioles. This so-called hyponastic response, in combination with stimulated petiole elongation, brings the leaf blade above the water surface and restores contact with the atmosphere. We made a detailed study of this differential growth process, encompassing the complete range of the known signal transduction ...
متن کاملO-20: The Combination of Basic Fibroblast Growth Factor and Follicular Stimulating Hormone Promotes Human Follicle Development In Vitro Culture
Background Fertility preservation is an important part of scientific study in the field of reproductive medicine. Ovarian cryopreservation and in vitro follicles culture provide option for fertility conservation in older women or cancer patients. Basic fibroblast growth factor (bFGF) or FGF-2, is member of fibroblast growth factors family which play critical roles in cell migration proliferatio...
