Stem hypertrophic lenticels and secondary aerenchyma enable oxygen transport to roots of soybean in flooded soil.
BACKGROUND AND AIMS Aerenchyma provides a low-resistance O(2) transport pathway that enhances plant survival during soil flooding. When in flooded soil, soybean produces aerenchyma and hypertrophic stem lenticels. The aims of this study were to investigate O(2) dynamics in stem aerenchyma and evaluate O(2) supply via stem lenticels to the roots of soybean during soil flooding. METHODS Oxygen ...
متن کاملAerenchyma formation and recovery from hypoxia of the flooded root system of nodulated soybean.
BACKGROUND AND AIMS Flooding results in hypoxia of the root system to which N2 fixation of nodulated roots can be especially sensitive. Morphological adaptions, such as aerenchyma formation, can facilitate the diffusion of oxygen to the hypoxic tissues. Using soybean, the aim of the study was to characterize the morphological response of the nodulated root system to flooding and obtain evidence...
متن کاملEffect of auxins and cytokinins on plant regeneration from hypocotyls and cotyledons in niger (Guizotia abyssinica
Guizotia abyssinica (L.f.) Cass. a indigenous medicinal and oil yielding plant of India and have been never studied scientifically for its beneficial effects. The present investigation was carried to study the standardization parameters of the plant and to evaluate the crude extracts for pharmacological potential to confirm and provide scientific basis for its use in traditional medicine and al...
متن کاملEffects of exogenous auxins on expression of lipoxygenases in cultured soybean embryos.
The expression of lipoxygenases (LOXs) is known to be developmentally regulated in soybeans (Glycine max. [L.] Merr.). Hormones have been firmly established as being involved in the growth and developmental processes of a number of plant species. Correlation between the expression of LOXs and the development and germination of soybean embryos suggests that plant hormones may affect the expressi...
