Phloem loading is a critical process in plant physiology. The potential of regulating the translocation photoassimilates from source to sink tissues represents an opportunity increase crop yield. Pyrophosphate homeostasis crucial for normal phloem function apoplasmic loaders. involvement Arabidopsis (Arabidopsis thaliana) type I proton-pumping pyrophosphatase (AVP1) was analyzed at genetic, histochemical, and physiological levels. A transcriptional AVP1 promoter::GUS fusion revealed activity...
Gold nanoparticle (AuNP)-mediated photothermal therapy represents an alternative to the effective ablation of cancer cells. However, response AuNPs must be tailored improve therapeutic efficacy plasmonic (PPT) and mitigate its side effects. This study presents ease tuning efficiency target selectivity. We use laser-treated spherical anisotropic different sizes biocompatible folic acid (FA)-conjugated (FA-AuNPs) in well-known human epithelial cervical (HeLa) cell line. show that large produce...
Ligand-targeted multifunctional nanoliposome combining NaYF<sub>4</sub>:Yb,Er nanoparticles for NIR-activated bioimaging and chemo-photodynamic therapy against HER2 positive breast cancer.
Gold nanoparticles (AuNPs) have a wide range of applications due to their optoelectronic properties. Particularly, biological synthesis AuNPs highlights the advantages related environmental care and stabilization provided by capping biomolecules during biosynthesis. The antimicrobial activity was reported, however, against resistant structures such as bacterial endospores not been evaluated. This work shows extracellular biosynthesis using Epicoccum nigrum (Au1-8) throughout an ecofriendly,...
Antifungal silver nanocomposites inspired by titanate nanotubes (AgTNTs) were successfully evaluated for the effective inactivation of phytopathogenic fungus Botrytis cinerea within 20 min. One-dimensional H2Ti3O7 functionalized with nanoparticles (AgNPs) exhibit unique surface and antifungal properties photoinactivation B. cinerea. Nanostructured titanates synthesized eco-friendly, practical, microwave-induced, hydrothermal method followed a highly monodispersive AgNP UV-photodeposition....
Some filamentous fungi of the Trichoderma genus are used as biocontrol agents against airborne and soilborne phytopathogens. The proposed mechanism by which spp. antagonizes phytopathogens is through release lytic enzymes, antimicrobial compounds, mycoparasitism, induction systemic disease-resistance in plants. Here we analyzed role TGF-1 (Trichoderma Gcn Five-1), a histone acetyltransferase atroviride, mycoparasitism antibiosis phytopathogen Rhizoctonia solani. Trichostatin A (TSA),...
PREMISE OF THE STUDY: During the interactions between a parasitic plant and its host, parasite affects host morphologically, anatomically, physiologically, yet there has been little focus on effect of hosts parasite. Here, functional hemiparasitic mistletoe Psittacanthus schiedeanus Liquidambar styraciflua Quercus germana were interpreted based anatomical features vascular tissues. METHODS: Using standard techniques for light transmission electron microscopy, we studied effects P. phloem...
Imposex is the development of male features in female prosobranch gastropods, caused by organotin compounds. In Mexican Pacific coast, imposex was observed Plicopurpura pansa. This snail has been used indigenous people to dye cotton and traditional fabric clothing. During 2010 2011, 5 habitats were visited along coastline Nayarit Sinaloa, Mexico. At low tide, 675 snails collected. Shell length, sex ratio incidence measured. incidences higher samples collected near harbor areas.
Calcium oxalate (CaOx) crystals in plants are formed crystal idioblasts cells and have specific geometric shapes. Their proposed functions include calcium homeostasis carbon source, among others. Amaranth is a plant that presents high tolerance to abiotic stresses accumulates considerable amounts of CaOx crystals; however, few studies focused on characterizing the ultrastructure none related identifying proteins bound them. This information great interest understand mechanisms formation...
To our knowledge, there are no studies about the structure and ecological function of extrafloral nectaries (EFNs) in Opuntia robusta. This is first description EFNs O. robusta, where young spines have an interesting a secreting function, which different from described other Cactaceae species. We used light, scanning-electron, transmission-electron microscopy to examine morphology, anatomy, ultrastructure secretory areoles female hermaphrodite individuals Young cladodes develop with modified...
Candida glabrata (CG) is an opportunistic fungal pathogen that initiates infection by binding to host cells via specific lectin-like adhesin proteins. We have previously shown the importance of lectin-oligosaccharide in cardiac responses flow and agonists. Because lectinic-oligosaccharide nature CG binding, we tested ability alter agonist- flow-induced changes function isolated perfused guinea pig hearts. Both transmission scanning electron microscopy showed strong attachment coronary...
Cowpea chlorotic mottle virus (CCMV) and brome mosaic (BMV) are naked plant viruses with similar characteristics; both form a T = 3 icosahedral protein capsid members of the bromoviridae family. It is well known that these completely disassemble liberate their genome at pH around 7.2 1 M ionic strength. However, strength condition not present inside cells, so an important question how deliver cells for viral replication. There some studies reporting swelling CCMV using different techniques....
A bioelectrochemical study of charge transfer in the biofilm–chalcopyrite interface was performed to investigate effect surficial reduced sulfur species (RSS), form non-stochiometric compounds or polysulfides (Sn2−) and elemental (S0) on a biofilm structure, during earliest stages (1, 12 24 h) chalcopyrite biooxidation by Acidithiobacillus thiooxidans alone adding Leptospirillum sp. The surface massive electrodes exposed bacteria, which were analyzed electrochemically, spectroscopically,...
