BACKGROUND It remains an open question whether plant phloem sap proteins are functionally involved in plant defense mechanisms. METHODS The antifungal effects of two profilin proteins from Arabidopsis thaliana, AtPFN1 and AtPFN2, were tested against 11 molds and 4 yeast fungal strains. Fluorescence

ATP-binding cassette (ABC) transporters hydrolyze ATP to transport a wide range of substrates. Fusarium graminearum is a major causal agent of Fusarium head blight, which is a severe disease in wheat worldwide. FgABCC9 (FG05_07325) encodes an ABC-C (ABC transporter family C) transporter in F.

Being natural plant antimicrobials, saponins have potential for use as biopesticides. Nevertheless, their activity in plant-pathogen interaction is poorly understood. We performed a comparative study of saponins' antifungal activities on important crop pathogens based on their effective dose

At least two components that modulate plant resistance against the fungal powdery mildew disease are ancient and have been conserved since the time of the monocot-dicot split (≈ 200 Mya). These components are the seven transmembrane domain containing MLO/MLO2 protein and the syntaxin ROR2/PEN1,

Oil bodies are localized in the seed cells and leaf cells of many land plants. They have a passive function as storage organelles for lipids. We recently reported that the leaf oil body has an active function as a subcellular factory that produces an antifungal oxylipin during fungal infection in

A novel antifungal protein, designated chrysancorin, was isolated from seeds of Chrysanthemum coronarium var. spatiosum with a procedure involving ion exchange chromatography on DEAE-cellulose, affinity chromatography on Affi-gel blue resin, ion exchange chromatography on SP-Sepharose and FPLC-gel

A novel antifungal peptide (termed as Anafp) was isolated from the culture supernatant of the filamentous fungi, Aspergillus niger. The whole amino acid sequence of Anafp was determined and the peptide was found to be composed of a single polypeptide chain with 58 amino acids including six cysteine

Transient receptor potential (TRP) channels, an ancient family of cation channels, are highly conserved in eukaryotes and play various physiological functions, ranging from sensation of ion homeostasis to reception of pain and vision. Calcium-permeable TRP channels have been identified from the

The production of therapeutic proteins in plant seed augments alternative production platforms such as microbial fermentation, cell-based systems, transgenic animals, and other recombinant plant production systems to meet increasing demands for the existing biologics, drugs under evaluation, and

Thionins are plant antimicrobial peptides with antibacterial and antifungal activities. Thionin Thi2.1 cDNA from Arabidopsis thaliana was expressed in BVE-E6E7 bovine endothelial cell line and its activity was evaluated against Escherichia coli, Staphylococcus aureus, Candida albicans and different

A plant antifungal protein was purified from Arabidopsis thaliana leaves by using a typical procedure consisting of anion exchange chromatography and high-performance liquid chromatography. We determined the amino acid sequence of the purified protein using MALDI-TOF/MS analysis, and found that the

An antifungal protein, AtUSP protein (At3g53990), was isolated from Arabidopsis thaliana leaves by ion and size chromatography and sequenced by N-terminal sequencing. The AtUSP gene amplified from an Arabidopsis leaf cDNA library was transformed to Escherichia coli to express the AtUSP protein. The

Plants are one of the most economical platforms for large-scale production of recombinant proteins for biopharmaceutical and industrial uses. A large number of human recombinant proteins of therapeutic value have been successfully produced in plant systems. One of the main technical challenges of

In planta expression of recombinant antibodies recognizing pathogen-specific antigens has been proposed as a strategy for crop protection. We report the expression of fusion proteins comprising a Fusarium-specific recombinant antibody linked to one of three antifungal peptides (AFPs) as a method for

Amine fungicides are widely used as crop protectants. Their success is believed to be related to their ability to inhibit postlanosterol sterol biosynthesis in fungi, in particular sterol-Δ(8),Δ(7)-isomerases and sterol-Δ(14)-reductases, with a concomitant accumulation of toxic abnormal sterols.
