A few years ago it was demonstrated that nitric oxide (NO) and cGMP are involved in the auxin response during adventitious root (AR) formation in cucumber (Cucumis sativus). More recently, a mitogen-activated protein kinase cascade was shown to be induced by IAA in a NO-dependent, but cGMP-independent, pathway. In the present study, the involvement of Ca2+ and the regulation of Ca2+-dependent p...

Total syntheses of 4-methylthio-3-butenylisothiocyanate (MTBI, 1) and raphanusanin (2), which are growth inhibitors involved in the phototropism radish (Raphanus sativus) hypocotyls, were achieved from commercially available thiolane four five steps, respectively. MTBI (1) was prepared via ring opening with sodium azide, double bond introduction by oxidation, isothiocyanation. Cyclization to (2...

Impatiens is an ornamental member of family Balsaminaceae. This plant mostly propagated by vegetative technique, which generally time wasting process. It often multiplicities via seed but barricaded F1 sterility. In vitro culture walleriana has much significant function in fast proliferation with useful features and elicitation healthful disease-free plants. experiment was conducted to investig...

The roots curl in naphthylphthalamic acid1 (rcn1) mutant of Arabidopsis (Arabidopsis thaliana) has altered auxin transport, gravitropism, and ethylene response, providing an opportunity to analyze the interplay between ethylene and auxin in control of seedling growth. Roots of rcn1 seedlings were previously shown to have altered auxin transport, growth, and gravitropism, while rcn1 hypocotyl el...

Actinomycin D inhibited the synthesis of poly(A)-containing messenger RNA in healthy soybean (Glycine max [L.] Merr. cv. Harosoy 63) hypocotyls and in hypocotyls inoculated with the pathogenic fungus Phytophthora megasperma var. sojae A. A. Hildb., but had little effect on protein synthesis within 6 hours. Blasticidin S, conversely, inhibited protein synthesis in the hypocotyls without exhibiti...

one of the important methods of plant propagation in large scale so as genetic manipulation and artificial seed production is somatic embryogenesis technique. the obtained results from this methods related to different factors including condition of culture medium. therefore, the aim of this study conduction were determining the role of molybdenum during carrot petiole somatic embryogenesis. at...

Etiolated hypocotyls of the resistant soybean (Glycine max [L.] Merr.) cultivar Harosoy 63 became susceptible to Phytophthora megasperma (Drechs.) f.sp. glycinea (Hildeb.) Kuan and Erwin race 1 after treatment with abscisic acid. Susceptibility was expressed by increases in lesion size and a major decrease in accumulation of the isoflavonoid phytoalexin, glyceollin. In untreated hypocotyls, act...

Glucosinolates are secondary metabolites derived from amino acids. Upon hydrolysis by myrosinases, they produce a variety of biologically active compounds. In this study, the glucosinolate-myrosinase system was characterized in Arabidopsis suspension cells. A total of seven glucosinolates were identified and the myrosinase activity was determined. Plant suspension cells have been used as model ...
