1. Extended-Spectrum Beta-Lactamase Producing Strains of Escherichia Coli Isolated from Avian Cellulitis Lesions
ABSTRACT Avian cellulitis causes significant losses to the poultry industry. Avian-pathogenic Escherichia coli (APEC) is the etiological agent of that disease. This microorganism has zoonotic potential and may act as reservoir of antimicrobial-resistance genes. In this context, the production of extended-spectrum B-lactamase (ESBL) is one of the main antimic

2. Search for sources of resistance to Meloidogyne enterolobii in commercial and wild tomatoes
RESUMO Meloidogyne enterolobii (=M. mayaguensis) é um patógeno de plantas capaz de induzir galhas e reduzir produtividade de uma vasta gama de espécies hospedeiras. Este patógeno tem sido também reportado como ameaça global para a cultura do tomateiro (Solanum lycopersicum), principalmente, por causa da sua habilidade de suplantar a resistência a algu

3. Protocol adjustment improves the extraction of high-quality total RNA from common bean stems infected by Sclerotinia sclerotiorum
RESUMO O Straw Test é um ensaio desenvolvido para avaliar a resistência do feijoeiro ao mofo branco, no qual as hastes da planta são inoculados e os sintomas da doença são monitorados. É plausível admitir que a investigação da expressão gênica em tecidos infectados por patógenos possa ser estrategicamente interessante. No entanto, obter um RNA de

4. The combining ability of popcorn S7 lines for Puccinia polysora resistance purposes
ABSTRACT The present study resulted from the lack of information on the genotypic expression ruling the resistance to rust and on the main traits of economic importance to the herein addressed crop. The combining ability of 16 popcorn lines and hybrids was assessed in partial diallel cross in two representative locations in Rio de Janeiro State, Brazil, wher

5. Genome-wide characterization of the NRAMP gene family in Phaseolus vulgaris provides insights into functional implications during common bean development
Abstract Transporter proteins play an essential role in the uptake, trafficking and storage of metals in plant tissues. The Natural Resistance-Associated Macrophage Protein (NRAMP) family plays an essential role in divalent metal transport. We conducted bioinformatics approaches to identify seven NRAMP genes in the Phaseolus vulgaris genome, investigated the

6. Properties of the enzyme acetolactate synthase in herbicide resistant canola
ABSTRACT Mutations in the gene that encodes the enzyme acetolactate synthase (ALS), conferring plant resistance to ALS inhibitor herbicides, can reduce or inhibit enzymatic function. The objective of this work was to determine the functionality and kinetic characteristics of the enzyme ALS and evaluate the action of the herbicides imazapic (imidazolinone) an

7. Gene transfer utilizing pollen-tubes of Albuca nelsonii and Tulbaghia violacea
Abstract Developing a tissue culture-independent genetic transformation system would be an interesting technique for gene transfer in valuable medicinal and horticultural plants. Efficient gene delivery (Agrobacterium tumefaciens strain LBA 4404: harbouring PBI121 plasmid) was achieved with Km-resistant pollen grains (pollen tube technique) and were found to

8. Genome-wide Identification, Classification and Expression Analysis of the Mildew Resistance Locus O ( MLO ) Gene Family in Sweet Orange ( Citrus sinensis )
ABSTRACT Mildew resistance Locus O (MLO), a gene family specific to plants, plays significant roles in the resistance to powdery mildew (PM) and response to a variety of abiotic stresses, plant growth and development. Despite their importance as barley, rice, wheat, few studies are reported in dicots except Arabidopsis; no global analysis has been performed

9. Contribution of non-target-site resistance in imidazolinone-resistant Imisun sunflower
ABSTRACT The first commercial herbicide-resistant trait in sunflower (Helianthus annuus L.) is known as ‘Imisun’. Imidazolinone resistance in Imisun cultivars has been reported to be genetically controlled by a major gene (known as Imr1 or Ahasl1-1) and modifier genes. Imr1 is an allelic variant of the Ahasl1 locus that codes for the acetohydroxyacid syn

10. Genome-wide analysis of EgEVE_1, a transcriptionally active endogenous viral element associated to small RNAs in Eucalyptus genomes
Abstract Endogenous viral elements (EVEs) are the result of heritable horizontal gene transfer from viruses to hosts. In the last years, several EVE integration events were reported in plants by the exponential availability of sequenced genomes. Eucalyptus grandis is a forest tree species with a sequenced genome that is poorly studied in terms of evolution a

11. The PIN1 family gene PvPIN1 is involved in auxin-dependent root emergence and tillering in switchgrass
Abstract Switchgrass (Panicum virgatum L.; family Poaceae) is a warm-season C4 perennial grass. Tillering plays an important role in determining the morphology of aboveground parts and the final biomass yield of switchgrass. Auxin distribution in plants can affect a variety of important growth and developmental processes, including the regulation of shoot an

12. Auxinic herbicides, mechanisms of action, and weed resistance: A look into recent plant science advances
Auxin governs dynamic cellular processes involved at several stages of plant growth and development. In this review, we discuss the mechanisms employed by auxin in light of recent scientific advances, with a focus on synthetic auxins as herbicides and synthetic auxin resistance mechanisms. Two auxin receptors were reported. The plasma membrane receptor ABP1
