Characterisation, immunolocalisation and antifungal activity of a lipid transfer protein from chili pepper (Capsicum annuum) seeds with novel α‐amylase inhibitory properties
Physiologia Plantarum - Tập 142 Số 3 - Trang 233-246 - 2011
Mariângela S. S. Diz, André de Oliveira Carvalho, Suzanna F. F. Ribeiro, Maura Da Cunha, Leila Maria Beltramini, Rosana Rodrigues, Viviane Veiga do Nascimento, Olga Lima Tavares Machado, Valdirene Moreira Gomes
Lipid transfer proteins (LTPs) were thus named because they facilitate the transfer of lipids between membranes in vitro. This study was triggered by the characterization of a 9‐kDa LTP from Capsicum annuum seeds that we call Ca‐LTP1. Ca‐LTP1 was repurified, and in the...... hiện toàn bộ
Metabolite profile analysis: from raw data to regression and classification
Physiologia Plantarum - Tập 132 Số 2 - Trang 150-161 - 2008
Matthias Steinfath, Detlef Groth, Jan Lisec, Joachim Selbig
Successful metabolic profile analysis will aid in the fundamental understanding of physiology. Here, we present a possible analysis workflow. Initially, the procedure to transform raw data into a data matrix containing relative metabolite levels for each sample is described. Given that, because of experimental issues in the technical equipment, the levels of some metabolites cannot be univ...... hiện toàn bộ
Microalgae biotechnology in Nordic countries – the potential of local strains
Physiologia Plantarum - Tập 166 Số 1 - Trang 438-450 - 2019
Otilia Cheregi, Susanne Ekendahl, Johan Engelbrektsson, Niklas Strömberg, Anna Godhe, Cornelia Spetea
Climate change, energy use and food security are the main challenges that our society is facing nowadays. Biofuels and feedstock from microalgae can be part of the solution if high and continuous production is to be ensured. This could be attained in year‐round, low cost, outdoor cultivation systems using strains that are not only champion producers of desired compounds but also have robus...... hiện toàn bộ
Correlation between chlorophyllide esterification, Shibata shift and regeneration of protochlorophyllide650 in flash‐irradiated etiolated barley leaves
Physiologia Plantarum - Tập 121 Số 4 - Trang 556-567 - 2004
V. V. Rassadina, В. П. Доманский, Н. Г. Аверина, Siegrid Schoch, Wolfhart Rüdiger
The pigments of etiolated leaves of barley (Hordeum vulgare L.) were analysed during dark periods after flash illumination, and the results were compared with in vivo spectroscopy of the leaves. Pretreatment of the leaves with kinetin slightly stimulated and pretreatment with NaF and anaerobiosis inhibited the esterification of chlorophyllide ... hiện toàn bộ
Oxidative damage and defense mechanisms in primary leaves of Phaseolus vulgaris as a result of root assimilation of toxic amounts of copper
Physiologia Plantarum - Tập 96 Số 3 - Trang 506-512 - 1996
J. Weckx, H. Clijsters
We studied the sequence of several metabolic reactions, representative for oxidative damage and protection, in primary leaves of Phaseolus vulgaris (cv. Limburgse vroege) as a function of root assimilation of a toxic sublethal Cu concentration (630 μM). A transient increase of products of membrane peroxidation was observed in the primar...... hiện toàn bộ
Cytokinin‐binding proteins
Physiologia Plantarum - Tập 100 Số 3 - Trang 520-527 - 1997
Mathias Brault, Régis Maldiney, Émile Miginiac
This article is focused on the modalities of reception of cytokinins which remain largely unknown. It summarizes the main steps of the different protocols used to study cytokinin‐binding proteins (CBPs). We place emphasis on the significance and specificity of the detection according to the properties of the probes used: radioactive or photoreactive cytokinins, fluorescent anticytokinins, ...... hiện toàn bộ
The contribution of fructose 2,6‐bisphosphate to the regulation of sucrose synthesis during photosynthesis
Physiologia Plantarum - Tập 69 Số 2 - Trang 377-386 - 1987
Mark Stitt, Richard Gerhardt, Ingo Wilke, Hans‐Walter Heldt
This review discusses (a) how the concentration of fructose 2,6‐bisphosphate is controlled in spinach leaves, (b) how fructose 2,6‐bisphosphate and cytosolic metabolites control the cytosolic fructose‐1,6‐bisphosphatase (EC 3.1.3.11), and (c) how the activities of the fructose‐1,6‐bisphosphatase and of sucrose phosphate synthase (EC 2.3.1.14) are coordinated. These features provide the ele...... hiện toàn bộ
Characterization of potato tuber lipoxygenase cDNAs and lipoxygenase expression in potato tubers and leaves
Physiologia Plantarum - Tập 102 Số 2 - Trang 257-271 - 1998
Ana Fidantsef, Richard M. Bostock
A collection of cDNAs was isolated from a λgt11 potato (Solanum tuberosum L.) tuber library by using a soybean lipoxygenase (LOX; linoleate:oxygen oxidoreductase, EC 1.13.11.12) sequence as a hybridization probe. These cDNA clones were classified by restriction patterns and sizes and two clones, plox1 and plox...... hiện toàn bộ
Phenoloxidase of peach (Prunus persica) endocarp: Its relationship with peroxidases and lignification
Physiologia Plantarum - Tập 109 Số 4 - Trang 382-387 - 2000
Claudia Mónica Alba, Silvia Milrad de Forchetti, Horacio A. Tigier
A preliminary characterization of a phenoloxidase from extracts of soluble and ionically‐bound cell wall proteins of peach (Prunus persica L. Batsch, cv. Redhaven) endocarp is described in the present study to establish differences with peroxidases from the same plant tissue. The phenoloxidase activity was detected mainly in the first stage of peach fruit growth,...... hiện toàn bộ
Uptake of atmospheric 15NO2 and its incorporation into free amino acids in wheat (Triticum aestivum)
Physiologia Plantarum - Tập 94 Số 1 - Trang 71-77 - 1995
Paul L. Weber, S Nussbaum, Jürg Fuhrer, Hans Gfeller, U. P. Schlunegger, Christian Brunold, Heinz Rennenberg
Five‐week‐old wheat plants were exposed, under controlled environmental conditions, to 60 nl 1−115NO2 or to purified air. After 48 and 96 h of exposure, leaves, stalks and roots were analysed for 15N‐enrichment in α‐amino nitrogen of soluble, free amino acids. In addition, the in vitro nitrate reductase (NR...... hiện toàn bộ
