Silicon (Si) is the second most abundant element in soils, and at elevated concentration levels in plant tissue Si is reported to improve plant resistance to a range of biotic and abiotic stresses. in the present study, Si solutions at 100, 300 or 500 mg l-1 made from potassium silicate (K2Sio3) were applied as foliar sprays or soil drenches to pepper (capsicum annum l.) plants, and their effec...

Understanding the synergic interactions between arbuscular mycorrhizal fungi (AMF) and its host mulberry (Morus alba L.), an important perennial multipurpose plant, has theoretical and practical significance in mulberry plantation, silkworm cultivation, and relevant textile industry. In a greenhouse study, we compared functional distinctions of three genetically different AMF species (Acaulospo...

In exploratory data analysis, important analysis tasks include the assessment of similarity of data points, labeling of outliers, identifying and relating groups in data, and more generally, the detection of patterns. Specifically, for large data sets, such tasks may be effectively addressed by glyph-based visualizations. Appropriately defined glyph designs and layouts may represent collections...

Previous studies on cytokinin (CK) and drought have suggested that the hormone has positive and negative effects on plant adaptation to restrictive conditions. This study examined the effect of CK on transpiration, stomatal activity, and response to drought in tomato (Solanum lycopersicum) plants. Transgenic tomato plants overexpressing the Arabidopsis thaliana CK-degrading enzyme CK oxidase/de...

The regulation of organ size in higher organisms is a fundamental issue in developmental biology. In flowering plants, a phenomenon called "compensation" has been observed where a cell proliferation defect in developing leaf primordia triggers excessive cell expansion. As a result, final leaf size is not significantly reduced compared to that expected from the reduction in leaf cell numbers. Re...

Abstract Leaf spinescence in pineapple plants was evaluated a total of 2.014 F1 individuals as follows: 1.125 the progeny Imperial BRS cv. × Perola cross, and 889 Pico de Rosa cross. The genetic hypothesis with two loci epistatic interaction piping (P) over spiny (S) trait tested. chi-square test performed on deviations between observed expected numbers based hypotheses formulated. “BRS Imperia...

Cotton leaf curl disease (CLCuD) is a severe disease of cotton that occurs in Africa and Pakistan/northwestern India. The disease is caused by begomoviruses in association with specific betasatellites that differ between Africa and Asia. During survey of symptomatic cotton in Sindh (southern Pakistan) Cotton leaf curl Gezira virus (CLCuGV), the begomovirus associated with CLCuD in Africa, was i...

Background & Aim: This experiment investigated the effect of foliar application of methanol and ethanol on the biomass yield of medicinal plant Echinacea purpurea. Purple coneflower is an herbaceous perennial in the Asteraceae family that is used in therapy of respiratory tract infection and bacterial otitis. Experimental: This experiment was conducted in randomized complete ...
