maltose/タバコ属

Maltose-binding protein (MBP) is a part of the complex regulatory and transport maltose system of Escherichia coli that is responsible for the uptake and efficient catabolism of maltodextrins through the transmembrane signaling at the expense of ATP. In the present work, this bacterial periplasmic

The C-terminal catalytic domain of tobacco N-acetylglucosaminyltransferase I fused to maltose-binding protein was produced in Escherichia coli as a soluble form with significant activity. The protein was affinity-purified using amylose resin, and its enzymatic properties were investigated, including

Pollen tube growth is influenced by interaction between pollen proteins and the pistil extracellular matrix. The transmitting tract-specific glycoprotein (NaTTS) and 120-kDa glycoprotein (120K) are two pistil arabinogalactan proteins (AGPs) that share a conserved C-terminal domain (CTD) and directly

The influence of sugars in culture media on the kinetics of the mono- and disaccharide uptake and cell growth behavior was studied by mid-infrared spectroscopy using a Fourier transform infrared spectrometer (FT-IR) equipped with an attenuate total reflection accessory (ATR). We performed the plant

Elicitins produced by the pathogenic fungi Phytophthora are known to exhibit The elicitin cinnamomin is of nonspecific toxicity to different solanaceous plant species. particular interest for its potential role in the hypersensitive-like cell death and in the biological response of cranberry plants

The movement protein of red clover necrotic mosaic virus (RCNMV) was expressed in Escherichia coli as a fusion with a maltose-binding protein using the vector pMAL-cRI and used to produce an antiserum. The RCNMV movement protein was detected in a cell wall fraction obtained from infected Nicotiana

Sucrose (Suc)-phosphate synthase (SPS) plays a crucial role in the synthesis of Suc in photosynthetic and nonphotosynthetic tissues. Several isoforms of SPS exist in dicotyledonous plants that can be grouped into the different families A, B, and C. To explore whether functional differences between

Two genes encoding the auxin-binding protein (ABP1) of tobacco (Nicotiana tabacum L.), both of which possess the characteristics of a luminal protein of the endoplasmic reticulum (ER), were isolated and sequenced. These genes were composed of at least five exons and four introns. The two coding

β-Amylase (BAM) catalyses starch breakdown to generate maltose, which can be incorporated into sugar metabolism. However, the role of BAM genes in cold tolerance is less characterized. In this study, we report the isolation and functional characterization of a chloroplast-localizing BAM-encoding

Starch synthesis in leaves was increased by phosphate starvation or by treatments which decreased cytoplasmic orthophosphate levels (such as mannose feeding). Usually less than 30% of the total carbon fixed during CO(2) assimilation was incorporated into starch in spinach (Spinacia oleracea L.),

Transitory starch, a major photosynthetic product in the leaves of land plants, accumulates in chloroplasts during the day and is hydrolyzed to maltose and Glc at night to support respiration and metabolism. Previous studies in Arabidopsis thaliana indicated that the degradation of transitory starch

β-Amylase (BAM) is involved in sugar metabolism, but the role of BAM genes in cold tolerance remains poorly understood. Here, we report the identification and functional characterization of the chloroplast-localized BAM-encoding gene PbrBAM3 isolated from Pyrus betulaefolia. The transcript levels of

All RNA viruses encode an RNA-dependent RNA polymerase (RdRP) that is required for replication of the viral genome. Nuclear inclusion b (NIb) gene codes for the RdRp in Potyviridae viruses. In this study, expression, solubilization and purification of NIb protein of Cardamom mosaic virus (CdMV) is

Ralstonia solanacearum (Smith) Yabuuchi et al. causes bacterial wilt worldwide on a wide range of plant species. In Mali, the disease is commonly found on potato (Solanum tuberosum L.), tomato (Lycopersicon esculentum var. esculentum L.), pepper (Capsicum annuum L.), eggplant (Solanum melongena L.),

Fruit rot disease (FRD), an emerging problem of tinda (Praecitrullus fistulosus) in India. FRD epidemics begin during rainy and warm weather and often spoil marketable produce. Symptoms appear as numerous, pale brown-to-dark brown, deeply penetrating circular soft rot lesions on fleshy fruit
