Typhi to melianone, resulting in the altered homeostasis of formate.An extracellular fructosyltransferase (Ftase) enzyme with a molar mass of ≈70 kDa from a newly isolated indigenous coprophilous fungus Aspergillus niger sp. XOBP48 is purified to homogeneity and characterized in this study. The enzyme was purified to 4.66-fold with a total yield of 15.53% and specific activity of 1219.17 U mg-1 of protein after a three-step procedure involving (NH4)2SO4 fractionation, dialysis and anion exchange chromatography. Ftase showed optimum activity at pH 6.0 and temperature 50 °C. Ftase exhibited over 80% residual activity at pH range of 4.0-10.0 and ≈90% residual activity at temperature range of 40-60 °C for 6 h. Metal ion inhibitors Hg2+ and Ag+ significantly inhibited Ftase activity at 1 mmol concentration. Ftase showed Km, vmax and k cat values of 79.51 mmol, 45.04 µmol min-1 and 31.5 min-1, respectively, with a catalytic efficiency (kcat/Km) of 396 µmol-1 min-1 for the substrate sucrose. HPLC-RI experiments identified the end products of fructosyltransferase activity as monomeric glucose, 1-kestose (GF2), and 1,1-kestotetraose (GF3). This study evaluates the feasibility of using this purified extracellular Ftase for the enzymatic synthesis of biofunctional fructooligosaccharides.Co-occurrence of two devastating foliar-fungal diseases of peanut, viz., late leaf spot (LLS), and rust may cause heavy yield loss besides adversely affecting the quality of kernel and fodder. This study reports the mapping of seven novel stress-related candidate EST-SSRs in a region having major QTLs for LLS and rust diseases using an F2 mapping population (GJG17 × GPBD4) consisting of 328 individuals. The parental polymorphism using 1311 SSRs revealed 84 SSRs (6.4%) as polymorphic and of these 70 SSRs could be mapped on 14 linkage groups (LG). QTL analysis has identified a common QTL (LLSQTL1/RustQTL) for LLS and rust diseases in the map interval of 1.41 cM on A03 chromosome, explaining 47.45% and 70.52% phenotypic variations, respectively. Another major QTL for LLS (LLSQTL1), explaining a 29.06% phenotypic variation was also found on LG_A03. selleck inhibitor A major rust QTL has been validated which was found harboring R-gene and resistance-related genes having a role in inducing hypersensitive response (HR). Further, 23 linked SSRs including seven novel EST-SSRs were also validated in 177 diverse Indian groundnut genotypes. Twelve genotypes resistant to both LLS and rust were found carrying the common (rust and LLS) QTL region, LLS QTL region, and surrounding regions. These identified and validated candidate EST-SSR markers would be of great use for the peanut breeding groups working for the improvement of foliar-fungal disease resistance.Spectral quality is an important factor for in vitro development of explants in a bioreactor system. Based on the need to optimize micropropagation for E. grandis × E. urophylla clones, the aim of the study was to assess the spectral quality of in vitro multiplication in temporary immersion bioreactor (TIB). The tissue used to generate the explants (i.e., the nodal segment with 1 cm of length and two axillary bud without leaves) was previously in vitro established and multiplied, it derived from ministumps of E. grandis × E. urophylla clone grown in a semi-hydroponic system. The spectral quality of in vitro multiplication was assessed through five light sources (i.e., fluorescent lamp, red, green, blue, and yellow cellophane). Morphological and anatomical features of tissues grown in TIB were evaluated at 90 days. Based on the results, yellow and blue spectral qualities were the most suitable to be adopted for in vitro multiplication of E. grandis × E. urophylla, since they enabled lesser hyperhydricity, favors high number of shoots per explant and shoot length, as well as thicker mesophyll and spongy parenchyma; arise as an alternative for large-scale production of eucalypts clonal plants.This study describes the abundance of multidrug-resistant Vibrios associated with marine invertebrate hosts from the Andaman Sea, India. Thirty-eight Vibrio strains were isolated from surface mucus layers of coral Porites, Goniastrea, Pocillopora, Fungia, and eggs of spiny lobster (Panulirus penicillatus). Phenotypically, the majority of strains exhibited growth at a wide range of temperatures, salt tolerance, and diverse nutritional requirements. All the strains had more than 97% 16S rRNA sequence similarity with type species of the genus Vibrio where Vibrio fortis, and Vibrio alginolyticus were predominant. Multilocus Sequence Analysis (MLSA) using eight housekeeping genes namely ftsZ, gapA, gyrB, mreB, pyrH, recA, rpoA, and topA distributed the strains into 6 reported clades i.e., Harveyi, Ponticus, Nereis, Orientalis, Splendidus, and Mediterranei where nearly half of the total strains represented the clade Harveyi, followed by the clade Splendidus. Likewise, the PFGE profile indicated genomic heterogeneity among the strains resulting in their distribution in five major clusters. Resistance to different antimicrobials was tested following the disc diffusion method where all strains were found susceptible to chloramphenicol (30 µg) and resistant to streptomycin (10 µg), vancomycin (30 µg), sulfamethoxazole-trimethoprim (25 µg). Moreover, the resistant phenotype to other antimicrobials confirmed the abundance of multidrug resistance strains in this marine environment.Erysipelothrix rhusiopathiae VR-2 is a commercially available live attenuated vaccine strain widely used in Russia, Kazakhstan, and a number of European countries for immunization of pigs against swine erysipelas. The draft genome sequence of E. rhusiopathiae strain VR-2 reported in this paper is 1,704,727 bp in length, has CG content of 36.5%, and contains 1680 genes, including 51 tRNA, 3 rRNA, and 1408 protein-coding genes. Comparative sequence analysis between Fujisawa (serovar 1a), VR-2 and six other serovar N strains of E. rhusiopathiae revealed wide genetic variability of the chromosomal region essential for serovar-specific antigenicity and virulence of E. rhusiopathiae strains. We have performed a BLAST search and found 12 genomic loci potentially specific for the E. rhusiopathiae VR-2 strain. These data could be helpful for developing genetic assays for differentiation of field isolates and this live attenuated vaccine strain, which is especially important for epizootical monitoring of swine erysipelas in countries, where the live vaccine strain E.
