The aims of this study were to induce calli from the seeds three rice varieties (Hommali 105, Munpu, and Niawdum) investigate their anti-aging potential. First, cultured on a Murashige Skoog medium (MS medium) supplemented with 2 mg/L 2,4-Dichlorophenoxyacetic acid (2,4-D), 1 1-Naphthalene acetic (NAA), 6-Benzylaminopurine (BAP). After weeks, extracted ethanol. Then, phenolic contents determine...

saffron is the dried stigmas of crocus sativus l., a member of the iridaceae family which ispropagated by means of corms. corms are faced with many stresses in soil. therefore, it isimportant to reduce these stresses and improve the quantity of saffron production. biotic andabiotic stresses disrupt the metabolic balance of cells; thereby, resulting in accumulation ofreactive oxygen species (ros...

Abstract Previous and recent literature acquisitions suggested that cultured calli are an efficient meaningful model to investigate the extent fate of prenylation phenylpropanoid cores in plants belonging Rutaceae Apiaceae families upon administration putative biosynthetic precursors. To this concern, present manuscript, we investigated effect supplementation ferulic acid umbelliferone on biosy...

The present study was the first report on somatic embryogenesis of Tunisian chickpea (Cicer arietinum L.) particularly supposed to be recalcitrant and difficult manipulate in vitro. An efficient protocol has been developed for inducing indirect derived from immature zygotic embryo axis, young leaflet hypocotylar explants. Callogenesis achieved full-strength Murashige Skoog's (1962) (MS) basal m...

of embryogenic frequency 88.9 and 72.23 were recorded for stem explants. However, the greatest embryogenic calli fresh weights 14.68 and 9.65 (mg/jar) were derived from leaf explants. Moreover, growth of somatic embryos was investigated during 7weeks. The highest regeneration percentage was achieved for stem explants compared other explants and recorded 88.88 and 66.66 for directly or indirectl...

A suspension tobacco (Nicotiana tabacum L.) cell line was transformed to express human lactoferrin, an iron-binding glycoprotein. The transgenic calli produced a protein that was significantly smaller than the full-length lactoferrin protein. Total protein extracts made from transgenic tobacco callus exhibited much higher antibacterial activity than commercially available purified lactoferrin a...

Callus cultures from stem of O. sanctum were induced on slightly modified Murashige and Skoog's (MS) medium and supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D, 1-2 ppm) and kinetin (kn, 1 ppm). Different extractives of stem, leaf and stem callus of O. sanctum were tested for anticonvulsant activity against standard drug phenytoin using maximal electroshock (MES) model. Ethanol and chlo...

Astragalus species are medicinal plants which produce valuable secondary metabolites, especially cycloartane-type glycosides. In this study, stem and leaf explants of Astragalus trojanus were subjected to different plant growth regulators, environmental conditions and media compositions to identify their callus responses. Stem and leaf explants were cultured in Murashige and Skoog (MS) and wood...
