Interaction of NPR1 with basic leucine zipper protein transcription factors that bind sequences required for salicylic acid induction of the PR-1 gene.

The Arabidopsis thaliana NPR1 has been shown to be a key regulator of gene expression during the onset of a plant disease-resistance response known as systemic acquired resistance. The npr1 mutant plants fail to respond to systemic acquired resistance-inducing signals such as salicylic acid (SA), or express SA-induced pathogenesis-related (PR) genes. Using NPR1 as bait in a yeast two-hybrid screen, we identified a subclass of transcription factors in the basic leucine zipper protein family (AHBP-1b and TGA6) and showed that they interact specifically in yeast and in vitro with NPR1. Point muta

Ammonium secretion during Colletotrichum coccodes infection modulates salicylic and jasmonic acid pathways of ripe and unripe tomato fruit.

The postharvest pathogens Colletotrichum coccodes remains quiescent after infection of unripe fruit. However, during fruit ripening, the pathogen assumes a necrotrophic life style, rapidly colonizing the tissue. C. coccodes secretes ammonium during germination and colonization of host tissue that induces host programmed cell death. We further examined the role of ammonia in the infection process by analyzing transcriptome expression from infected and ammonia-treated fruit tissue compared with healthy tissue. The analysis revealed 82 and 237 common upregulated and downregulated genes, respectiv

Intravenous Administration of Lycopene, a Tomato Extract, Protects against Myocardial Ischemia-Reperfusion Injury.

BACKGROUND: Oral uptake of lycopene has been shown to be beneficial for preventing myocardial ischemia-reperfusion (I/R) injury. However, the strong first-pass metabolism of lycopene influences its bioavailability and impedes its clinic application. In this study, we determined an intravenous (IV) administration dose of lycopene protects against myocardial infarction (MI) in a mouse model, and investigated the effects of acute lycopene administration on reactive oxygen species (ROS) production and related signaling pathways during myocardial I/R. METHODS: In this study, we established both in

Tomato LeTHIC is an Fe-requiring HMP-P synthase involved in thiamine synthesis and regulated by multiple factors.

Thiamine is a key primary metabolite which is necessary for the viability of all organisms. It is a dietary requirement for mammals because only prokaryotes, fungi and plants are thiamine prototrophs. In contrast to the well documented biosynthetic mechanism in bacteria, much remains to be deciphered in plants. In this work, a tomato thiamine-auxotrophic (thiamineless, tl) mutant was characterized. The tl mutant occurs due to inactivation of LeTHIC transcription as a result of insertion of a large unknown DNA fragment in its 5'-untranslated region. Expression of wild-type LeTHIC in tl plants w

Natural disulfide bond-disrupted mutants of AVR4 of the tomato pathogen Cladosporium fulvum are sensitive to proteolysis, circumvent Cf-4-mediated resistance, but retain their chitin binding ability.

The extracellular AVR4 elicitor of the pathogenic fungus Cladosporium fulvum induces defense responses in the tomato genotype Cf-4. Here, the four disulfide bonds of AVR4 were identified as Cys-11-41, Cys-21-27, Cys-35-80, and Cys-57-72 by partial reduction with Tris-(2-carboxyethyl)-phosphine hydrochloride, subsequent cyanylation, and base-catalyzed chain cleavage. The resulting peptide fragments were analyzed by mass spectrometry. Sequence homology and the disulfide bond pattern revealed that AVR4 contains an invertebrate (inv) chitin-binding domain (ChBD). Binding of AVR4 to chitin was conf

Biotechnological potential of plant growth-promoting bacteria from the roots and rhizospheres of endemic plants in ironstone vegetation in southeastern Brazil.

Microorganisms associated with plants have a great biotechnological potential, but investigations of these microorganisms associated with native plants in peculiar environments has been incipient. The objective of this study was to analyze the plant growth-promoting bacteria potential of cultivable bacteria associated with rare plants from the ferruginous rocky fields of the Brazilian Iron Quadrangle. The roots and rhizospheres of nine endemic plants species and samples of a root found in a lateritiric duricrust (canga) cave were collected, the culturable bacteria isolated and prospected for d

Multiple RNA binding protein complexes interact with the rice prolamine RNA cis-localization zipcode sequences.

RNAs for the storage proteins, glutelins and prolamines, contain zipcode sequences, which target them to specific subdomains of the cortical endoplasmic reticulum in developing rice (Oryza sativa) seeds. Fifteen RNA binding proteins (RBPs) specifically bind to the prolamine zipcode sequences and are likely to play an important role in the transport and localization of this storage protein RNA. To understand the underlying basis for the binding of multiple protein species to the prolamine zipcode sequences, the relationship of five of these RBPs, RBP-A, RBP-I, RBP-J, RBP-K, and RBP-Q, were stud

Chemical Modification of 1-Aminocyclopropane Carboxylic Acid (ACC) Oxidase: Cysteine Mutational Analysis, Characterization, and Bioconjugation with a Nitroxide Spin Label.

1-Aminocyclopropane carboxylic acid oxidase (ACCO) catalyzes the last step of ethylene biosynthesis in plants. Although some sets of structures have been described, there are remaining questions on the active conformation of ACCO and in particular, on the conformation and potential flexibility of the C-terminal part of the enzyme. Several techniques based on the introduction of a probe through chemical modification of amino acid residues have been developed for determining the conformation and dynamics of proteins. Cysteine residues are recognized as convenient targets for selective chemical m

Evidence for a role of the N terminus and leucine-rich repeat region of the Mi gene product in regulation of localized cell death.

The tomato Mi gene confers resistance against root-knot nematodes and potato aphids. Chimeric constructs of the functional gene, Mi-1. 2, with a homolog, Mi-1.1, were produced, and their phenotypes were examined in Agrobacterium rhizogenes-transformed roots. Exchange of the leucine-rich repeat (LRR) region of Mi-1.1 into Mi-1.2 resulted in the loss of ability to confer nematode resistance, as did substitution of a 6-amino acid sequence from the Mi-1.1 LRR into Mi-1.2. Introduction of the Mi-1.2 LRR-encoding region into Mi-1.1 resulted in a lethal phenotype, as did substitution of the fragment

The Mediterranean Diet, a Rich Source of Angiopreventive Compounds in Cancer.

Diet-based chemoprevention of cancer has emerged as an interesting approach to evade the disease or even target its early phases, reducing its incidence or slowing down tumor progression. In its basis in the essential role of angiogenesis for tumor growth and metastasis, angioprevention proposes the use of inhibitors of angiogenesis in cancer prevention. The anti-angiogenic potential exhibited by many natural compounds contained in many Mediterranean diet constituents makes this dietary pattern especially interesting as a source of chemopreventive agents, defined within the angioprevention str

Vitamin C-Sources, Physiological Role, Kinetics, Deficiency, Use, Toxicity, and Determination.

Vitamin C (L-ascorbic acid) has been known as an antioxidant for most people. However, its physiological role is much larger and encompasses very different processes ranging from facilitation of iron absorption through involvement in hormones and carnitine synthesis for important roles in epigenetic processes. Contrarily, high doses act as a pro-oxidant than an anti-oxidant. This may also be the reason why plasma levels are meticulously regulated on the level of absorption and excretion in the kidney. Interestingly, most cells contain vitamin C in millimolar concentrations, which is much highe

Precision in Action: The Role of Clustered Regularly Interspaced Short Palindromic Repeats/Cas in Gene Therapies.

Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)-associated enzyme-CAS holds great promise for treating many uncured human diseases and illnesses by precisely correcting harmful point mutations and disrupting disease-causing genes. The recent Food and Drug Association (FDA) approval of the first CRISPR-based gene therapy for sickle cell anemia marks the beginning of a new era in gene editing. However, delivering CRISPR specifically into diseased cells in vivo is a significant challenge and an area of intense research. The identification of new CRISPR/Cas variants, particularly
