Abstract The SWEET (sugar will eventually be exported transporter) family proteins are a recently identified class of sugar transporters that are essential for various physiological processes. Although the functions of the SWEET proteins have been identified in a number of species, to date, there have been no reports of the functions of the SWEET genes in woodland strawberries (Fragaria vesca). In this study, we identified 15 genes that were highly homologous to the A. thaliana AtSWEET genes and designated them as FvSWEET1–FvSWEET15. We then conducted a structural and evolutionary analysis of these 15 FvSWEET genes. The phylogenetic analysis enabled us… More >

Abstract The sulfate groups in agar structure played a good role in the formation of fiber. However, commercially available agar is usually extracted from red algae by alkali treatment to decrease the content of sulfate group for the purpose of high gel strength. In this paper, an alkali-free method of agar extraction from Gracilaria lemaneiformis was proposed for the wet-spinning purpose. This method is environmentally friendly, reduces the extraction steps, saves energy, and reduces the production cost of agar fiber. The improved agar preparation process not only has higher agar yield, but also has higher molecular weight More > Graphic Abstract

Abstract Auxin signaling and its components (Auxin/Indole-3-Acetic Acid (Aux/IAA)) are critical for plant growth and development. Here, we performed a genome-wide annotation and identified twenty-one Aux/IAA genes in strawberry (Fragaria vesca). Most FveIAAs were located on chromosomes 1, 2, 4, 5, and 6, while no FveIAAs were found in chromosomes 3 and 7. Phylogenetic analysis divided these genes into nine subfamilies. Most FveIAAs contained the DNA-binding and Aux/IAA domains, as well as motifs I–IV. There were 2–6 exons in the FveIAA genes based on the gene structure analysis. Also, we found that four pairs of FveIAA genes underwent segment More >

Abstract Two methods were used to produce chitosan by deacetylation of chitin which was extracted from Agaricus bisporus stipes. The first one gives chitosan 1 with low yield of 2.5%, degree of acetylation (DA) of 4%, molecular weight (MW) of 2.973 × 10⁵ (g/mol). The second route produces chitosan 2 with higher yield of 41%, degree of acetylation (DA) of 17.23%, molecular weight (MW) of 2.939 × 10⁵ (g/mol). Both chitosans were characterized by XRD, FTIR, ¹ H-NMR spectroscopy nuclear magnetic resonance of proton. The molecular weight (M_W) was determined by size exclusion chromatography (SEC). Thermal analysis shows that More >

Abstract In this work, nine different types of edible coating based on pectin, cellulose nanocrystals, glycerol, and essential oil of lemongrass were prepared and used to coat strawberries with a film formed directly on the surface of the coated fruit. The effects of the different edible coatings on refrigerated fruits in terms of weight loss, titratable acidity, total soluble solids, pH, and anthocyanin content was evaluated after 2 days, 4 days, 6 days, and 8 days of storage. Application of the edible coatings reduced the weight loss of the coated strawberries and the anthocyanin content. The More >

Abstract Grading of writers in perspective of their handwriting is a challenging task owing to various writing styles of different individuals. This paper presents a framework for grading of Devanagari writers in perspective of their handwriting. This framework of grading can be useful in conducting the handwriting competitions and then deciding the winners on the basis of an automated process. Selecting the set of features is a challenging task for implementing a handwriting grading system of particular language. In this paper, curvature features, namely, parabola curve fitting and power curve fitting have been considered for extracting… More >
