The hydrophobic proteins of plant plasma membrane still remain largely unknown.  For example in the Arabidopsis genome, receptor-like kinases (RLKs) are plasma membrane proteins, functioning as the primary receptors in the signaling of stress conditions, hormones and the presence of pathogens form a diverse family of over 610 genes. A limited number of these proteins have appeard in pr...

The precursor form of the major-harvesting chlorophyll a/b-binding protein @LHCP) of chloroplast thylakoids was overproduced in E. coli cells and used to study the influence of soluble factors on post-translational protein import into isolated pea chloroplasts. pLHCP solubilised in 8 M urea was not import-competent. However, if pLHCP was dialysed in the presence of soluble proteins (leaf extrac...

To explore the function of light-harvesting complex protein (LHCP) in Arabidopsis growth and development, the Leclere and Bartel seed collection was screened. In this collection randomly cloned cDNAs are expressed under the CaMV35S promoter. A pale green line has been identified and characterized in more details. Analysis of the inserted cDNA in the pale green line showed it encodes LHCB1 prote...

Peanut genotypes from the US mini-core collection were analysed for changes in leaf proteins during reproductive stage growth under water-deficit stress. One- and two-dimensional gel electrophoresis (1- and 2-DGE) was performed on soluble protein extracts of selected tolerant and susceptible genotypes. A total of 102 protein bands/spots were analysed by matrix-assisted laser desorption/ionizati...

the effect of tricyclazole application on waterlogging damage alleviation in canola seedlings was evaluated in a pot experiment in complete randomized design layout with three replications. treatments included: control (no waterlogging), waterlogging, tricyclazole plus waterlogging and tricyclazole. tricyclazole (75%) applied at three-leaf stage on canola seedlings. seedlings were exposed to wa...

Biofertilizers, such as arbuscular mycorrhiza fungi (AMF) and seaweed extract (SWE), have been effective in environmental agricultural ecosystems. In this study, the effects of AMF, SWE, their co-application were assayed on growth antioxidant potential lettuce plants. The experiment was conducted a factorial based completely randomized design with two factors four replications under greenhouse ...

Rhizobial endophytes infect and colonize not only leguminous plants, but several non-leguminous species as well. Using green fluorescent protein tagging technique, it has been shown that Rhizobia infect different varieties of rice species and migrate from plant roots to aerial tissues such as leaf sheaths and leaves. The interaction between them was found to promote the growth of rice. The grow...

IIn this study, the effects of paraxanthin on lettuce were investigated. Paraxanthin is a group of purine alkaloids, secondary metabolites of plants. This compound is made up of the caffeine metabolism found in plants such as tea, coffee and cocoa. There have been previous reports of paraxanthine antihypertensive properties.Three different concentrations of paraxanthine as 10, 50 and 100 µg/ml ...

Alternaria sesami causes leaf spot disease in Sesamum orientale. Conidium germination, inoculation, penetration and colonization of the pathogen on the plant surfaces were studied using scanning electron microscopy. Electron microscopy analysis revealed multiple germ tubes from conidium that spread in all direction across the leaf surfaces. Penetration in the plant surface occured, directly thr...
