Phytic acid, a naturally occurring component, widely found in many plants, can strongly bond toxic mineral elements in human body due to its six phosphate groups. Some of the metal ions present the property of bonding with phytic acid to form insoluble coordination complexes aggregations even in room temperature. Herein, a superhydrophobic cotton fabric was prepared by a novel and facile nature-inspired strategy which introduced phytic acid metal complexes aggregations to generate rough hierarchical structures on fabric surface followed with PDMS modification...

The main aim of this study was to evaluate the effect of the source of microorganisms on the selection of hydrolytic consortia dedicated to anaerobic digestion of maize silage. The selection process was investigated based on the analysis of changes in the hydrolytic activity and the diversity of microbial communities derived from (i) a hydrolyzer of a commercial agricultural biogas plant, (ii) cattle slurry and (iii) raw sewage sludge, during a series of 10 passages. Following the selection process, the adapted consortia were thoroughly analyzed for their ability to utilize maize silage and augmentation of anaerobic digestion communities...

Dry root rot (DRR) caused by the fungus Rhizoctonia bataticola (Taub.) Butler, is an emerging disease in chickpea. The disease is often mistaken with other root rots like Fusarium wilt, collar rot and black root rot in chickpea. Therefore, its timely and specific detection is important. Current detection protocols are either based on mycological methods or on protocols involving DNA amplification by polymerase chain reaction (PCR). Here we report the rapid and specific detection of R. bataticola using loop-mediated isothermal amplification (LAMP) assay targeting fungal specific 5...

Taxol (paclitaxel) is a diterpenoid compound with significant and extensive applications in the treatment of cancer. The production of Taxol and relevant intermediates by engineered microbes is an attractive alternative to the semichemical synthesis of Taxol. In this study, based on a previously developed platform, we first established taxadiene production in mutant E. coli T2 and T4 by engineering of the mevalonate (MVA) pathway. We then developed an Agrobacterium tumefaciens-mediated transformation (ATMT) method and verified the strength of heterologous promoters in Alternaria alternata TPF6...

BACKGROUND: The traditional Chinese medicine (TCM) Qianhu and Zihuaqianhu are the dried roots of Peucedanum praeruptorum and Angelica decursiva, respectively. Since the plant sources of Qianhu and Zihuaqianhu are more complex, the chemical compositions of P. praeruptorum and A. decursiva are significantly different, and many adulterants exist because of the differences in traditional understanding and medication habits. Therefore, the rapid and accurate identification methods are required...

What is fascinating in plants (true also in sessile animals such as corals and hydroids) is definitely their open and indeterminate growth, as a result of meristematic activity. Plants as well as animals are characterized by a multicellular organization, with which they share a common set of genes inherited from a common eukaryotic ancestor; nevertheless, circa 1.5 billion years of evolutionary history made the two kingdoms very different in their own developmental biology. Flowering plants, also known as angiosperms, arose during the Cretaceous Period (145-65 million years ago), and up to date, they count around 235,000 species, representing the largest and most diverse group within the plant kingdom...

Biosolids originating from Municipal Waste Water Treatment Plants are proposed as top soil improvers (TSI) for their beneficial input of organic carbon on agriculture lands. Their use to amend soil is controversial, as it may lead to the presence of emerging hazards of anthropogenic or animal origin in the environment devoted to food production. In this study, we used a shotgun metagenomics sequencing as a tool to perform a characterization of the hazards related with the TSIs. The samples showed the presence of many virulence genes associated to different diarrheagenic E...

HYPOTHESIS: Nanocrystalline cellulose (NCC) is a negatively charged rod-like colloid obtained from the hydrolysis of plant material. It is thus expected that NCC suspensions display a rich set of phase behaviour with salt and pH because of its anisotropic shape and electrical double layer that gives rise to liquid crystallinity and self-assembly respectively. It should thus be possible to tune the rheological properties of NCC suspensions for a wide variety of end-use applications. EXPERIMENTS: Rheology and structural analysis techniques are used to characterise surface-sulphated NCC suspensions as a function of pH, salinity (NaCl) and NCC concentration...

Rice grassy stunt virus (RGSV) is a tenuivirus posing a threat to rice production in many South, Southeast, and East Asian countries. To date, no host factor interacting with RGSV has been reported. In this study, we screened a rice cDNA library with the GAL4-based yeast two-hybrid system using RGSV p5 as the bait. One of the candidate host factors interacting with RGSV p5 was found to be CBL-interacting protein kinase 25 (OsCIPK25), a member of the plant-specific CBL-CIPK Ca(2+) signaling network. The interaction between RGSV p5 and OsCIPK25, as well as OsCIPK5, which is closely related to OsCIPK25, was confirmed by their cellular co-localization and by a bimolecular fluorescence complementation assay in Nicotiana benthamiana cells...

Nitric oxide (NO) raises the intracellular 3',5'-cyclic guanosine monophosphate (cGMP) level through the activation of soluble guanylate cyclase and, in the presence of reactive oxygen species (ROS), reacts with biomolecules to produce nitrated cGMP derivatives. 8-Nitro-cGMP was the first endogenous cGMP derivative discovered in mammalian cells (2007) and was later found in plant cells. Among the six nitrogen atoms in this molecule, the one in the nitro group (NO2) comes from NO. This chapter asserts that this newly found cGMP is undoubtedly one of the major physiological cNMPs...

Pseudomonas sp. M1 is able to mineralize highly hydrophobic and recalcitrant compounds such as benzene, phenol and their methylated/halogenated derivatives, as well as the backbone of several monoterpenes. The ability to use such spectrum of compounds as sole carbon source is, most probably, associated with a genetic background evolved under different environmental constraints. The outstanding performance of M1 strain regarding β-myrcene catabolism was elucidated in this work, with focus on the biocatalytical potential of β-myrcene-associated core-code, comprised in a 28-kb genomic island (GI), predicted to be organized in 8 transcriptional units...

Understanding the genomic complexity of bread wheat (Triticum aestivum L.) is a cornerstone in the quest to unravel the processes of domestication and the following adaptation of domesticated wheat to a wide variety of environments across the globe. Additionally, it is of importance for future improvement of the crop, particularly in the light of climate change. Focussing on the adaptation after domestication, a nested association mapping (NAM) panel of 60 segregating bi-parental populations were developed mainly involving landrace accessions from the core set of the Watkins hexaploid wheat collection optimized for genetic diversity (WINGEN et al...

The role of ready-to-eat products as a reservoir of pathogenic species of Acinetobacter remains unclear. The objective of the present study was to evaluate the presence of Acinetobacter species in lettuces and fruits marketed in Portugal, and their susceptibility to antimicrobials. Acinetobacter spp. were isolated from 77.9% of the samples and these microorganisms were also found as endophytes (i.e. present within the plant tissue) in 12 of 20 samples of lettuces analysed. Among 253 isolates that were identified as belonging to this genus, 181 presented different PFGE profiles, representing different strains...
