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
Turgor‐sensitive sucrose and amino acid transport into developing seeds of Pisum sativum. Effect of a high sucrose or mannitol concentration in experiments with empty ovules
Physiologia Plantarum - Tập 61 Số 2 - Trang 172-182 - 1984
P. Wolswinkel, Ankie Ammerlaan
Sugar and amino acid transport into empty ovules of Pisum sativum L. cv. Marzia was examined. In fruits containing 4–6 developing seeds, the embryo was removed from four ovules. After this surgical treatment, each empty seed coat was filled with a solution (pH 5.5) containing a low (0, 50 or 200 mM), medium (350, 400 or 500 m... hiện toàn bộ
Characterization of glycine‐rich RNA‐binding proteins in Brassica napus under stress conditions
Physiologia Plantarum - Tập 146 Số 3 - Trang 297-307 - 2012
Min Kyung Kim, Hyun‐Ju Jung, Dong Hyun Kim, Hunseung Kang
Although the functional roles of glycine‐rich RNA‐binding proteins (GRPs) during stress adaptation have been extensively evaluated in Arabidopsis thaliana and rice (Oryza sativa), the stress‐responsive roles of a majority of GRPs have not been characterized in other plant species including rapeseed (Brassica napus... 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
Drought acclimation confers oxidative stress tolerance by inducing co‐ordinated antioxidant defense at cellular and subcellular level in leaves of wheat seedlings
Physiologia Plantarum - Tập 127 Số 3 - Trang 494-506 - 2006
Devarshi Selote, Renu Khanna‐Chopra
Wheat (Triticum aestivum L.) seedlings of a drought‐resistant cv. C306 were subjected to severe water deficit directly or through stress cycles of increasing intensity with intermittent recovery periods (drought acclimation). The antioxidant defense in terms of redox metabolites and enzymes in leaf cells, chloroplasts, and mitochondria was examined in relation to...... hiện toàn bộ
Pyridine nucleotide cycle and trigonelline (N‐methylnicotinic acid) synthesis in developing leaves and fruits of Coffea arabica
Physiologia Plantarum - Tập 122 Số 4 - Trang 404-411 - 2004
Xin‐Qiang Zheng, Chifumi Nagai, Hiroshi Ashihara
We examined the biosynthesis of trigonelline in leaves and fruits of Arabica coffee (Coffea arabica) plants. [3H]Quinolinic acid, which is an intermediate of de novo pyridine nucleotide synthesis, and [14C]nicotinamide and [14C]nicotinic acid, which are degradation products of NAD, were co...... 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
Organic Growth Factor Requirements of Tobacco Tissue Cultures
Physiologia Plantarum - Tập 18 Số 1 - Trang 100-127 - 1965
Elfriede M. Linsmaier, Folke Skoog
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
