The polypeptide patterns obtained by sodium dodecylsulphate-polyacrylamide gel electrophoresis of undigested and autodigested extracts from pea (Pisum sativum L.) ovaries at the early stages of development or degeneration have been studied. Development of unpollinated ovaries was stimulated by
Small pieces of tissue from the basal, equatorial, near-apical, and apical regions of the third turgid onion leaf base were treated (3 and 6 h in the dark) with abscisic acid (ABA), gibberellic acid (GA3), indoleacetic acid (IAA), and kinetin (K) and compared with responses in water controls. ABA
The current work intended to inspect the hepato-nephrotoxicity of gibberellic acid (GA3) in juvenile of Oreochromis niloticus as well as the possibility of restoration after dietary addition of different concentrations of Spirulina platensis (SP). Fishes were evenly assorted into five
Fluorescence staining and morphometrical measurements revealed that callose was a component of newly formed cell plates of symmetrically dividing cells and asymmetrically dividing antheridial mother cells during gibberellic acid-induced antheridiogenesis as well as in walls of young growing cells of
Gibberellic acid (GA3), a plant growth regulator, is widely used in agriculture in many countries to accelerate the growth of fruits and vegetables. We designed histological, immunohistochemical, and biochemical studies to evaluate the deleterious effects of GA3 on the livers of adult pregnant rats
The present study aims to investigate the heptonephro-protective effect of grape seeds proanthocyanidin extract (GSPE) against the risks induced by gibberellic acid (GA3) in male rats. The results recorded that GA3 caused a significant increase in total lipids, total cholesterol, triglycerides and
Seed longevity is the period during which the plant seed is able to germinate. This property is strongly influenced by environment conditions experienced by seeds during their formation and storage. In the present study we have analyzed how the biotic stress derived from the infection of Cauliflower
Natural floral organ degeneration or abortion results in unisexual or fully sterile flowers, while abiotic stresses lead to sterility after initiation of floral reproductive organs. Since normal flower development is essential for plant sexual reproduction and crop yield, it is imperative to have a
The present study aims to investigate the adverse effects of plant growth regulators : gibberellic acid (GA3) and indoleacetic acid (IAA) on testicular functions in rats, and extends to investigate the possible protective role of grape seed extract, proanthocyanidin (PAC). Male rats were divided
Changes in germination, seedling growth, respiration, response to applied gibberellic acid, and glucose-U-(14)C utilization were investigated in partially dormant wheat (Triticum aestivum L., Pa 151 x 107) seeds which were stored under various conditions for periods up to 1 year. Only seeds stored
The aim of the present study was to investigate the protective role of grape seed extract (containing proanthocyandin) against the adverse effects of plant growth regulators (GA3 (gibberellic acid) and IAA (indoleacetic acid)). The present data showed that the administration of either GA3 and IAA
The tapetum is a layer of cells covering the inner surface of pollen sac wall. It contributes to anther development by providing enzymes and materials for pollen coat biosynthesis and nutrients for pollen development. At the end of anther development, the tapetum is degenerated, and the anther is
Arbuscular mycorrhizal (AM) fungi, in symbiosis with plants, facilitate acquisition of nutrients from the soil to their host. After penetration, intracellular hyphae form fine-branched structures in cortical cells termed arbuscules, representing the major site where bidirectional nutrient exchange
