The beta-amyloid peptide, the hallmark of Alzheimer disease, forms fibrillar toxic aggregates in brain tissue that can be dissolved only by strong denaturing agents. To study formation and its inhibition, we prepared immune complexes with two monoclonal antibodies (mAbs), AMY-33 6F/3D, raised against fragments spanning amino acid residues 1-28 8-17 peptide chain, respectively. In vitro aggregation was induced incubation for 3 h at 37 degrees C monitored ELISA, negative staining electron...
Abstract Weed management is a critically important activity on both agricultural and non‐agricultural lands, but it faced with daunting set of challenges: environmental damage caused by control practices, weed resistance to herbicides, accelerated rates dispersal through global trade, greater impacts due changes in climate land use. Broad‐scale use new approaches needed if be successful the coming era. We examine three likely prove useful for addressing current future challenges from weeds:...
Summary Phelipanche and Orobanche species (broomrapes) are root holoparasitic plants that cause severe damage to economically important crops. spp. widespread in Mediterranean areas, Asia Southern Eastern Europe, attacking dicotyledonous crops depending entirely on their hosts for all nutritional requirements. aegyptiaca , ramosa cernua extremely troublesome weeds tomatoes. These noxious parasites exert greatest prior shoot emergence flowering; therefore, the majority of field loss may occur...
The obligate root parasitic weeds commonly known as broomrape (Orobanche and Phelipanche spp.) cause severe damage to vegetable field crops worldwide. Efficient control of these parasites is difficult due their development attachment the host plant (via a specialized organ, haustorium) under soil surface unique biological traits massive seed production, facile dispersal, germination only specific conditions, longevity. major inflicted by takes place underground, making extremely challenging....
Abstract The adoption of site‐specific weed management (SSWM) technologies by farmers is not aligned with the scientific achievements in this field. While scientists have demonstrated significant success real‐time identification, phenotyping and accurate mapping using various sensors platforms, integration SSWM tools into protocols limited. This gap was therefore a central topic discussion at most recent workshop Working Group arranged European Weed Research Society (EWRS). insight paper...
Broomrapes ( Orobanche and Phelipanche spp.) are obligate root parasites that spend most of their life cycle in the soil subsurface, making them hard to detect. In these underground developmental stages, broomrapes highly sensitive herbicides, therefore knowledge dynamics parasitism is essential precisely apply herbicide for control. To address complexities, two approaches have been proposed: (1) estimating temporal variation predicting broomrape on its host by thermal time; (2)...
Summary Transdisciplinary weed research ( TWR ) is a promising path to more effective management of challenging problems. We define as an integrated process inquiry and action that addresses complex problems in the context broader efforts improve economic, environmental social aspects ecosystem sustainability. seeks integrate scholarly practical knowledge across many stakeholder groups (e.g. scientists, private sector, farmers extension officers) levels local, regional landscape)....
Abstract Atrazine is an herbicide and a pollutant of great environmental concern that naturally biodegraded by microbial communities. Paenarthrobacter aurescens TC1 one the most studied degraders this herbicide. Here, we developed genome scale metabolic model for P. TC1, i RZ1179, to study atrazine degradation process at organism level. Constraint based flux balance analysis time dependent simulations were used explore organism’s phenotypic landscape. Simulations aimed designing media...
Abstract Mechanical weed control tools are commonly used in the production of many vegetable and field crops. This study aimed to determine impact species growth stage on finger weeder performances reveal relation between root morphology, uprooting force efficacy. A one‐month experiment with two model species, Triticum aestivum L. (grass) Sinapis alba (broadleaf), showed that efficacy was affected by stage: Finger‐weeder application during first stages (cotyledon second leaf) more effective...
Weeds of the genus Orobanche parasitize many dicotyledonous species, causing severe damage to vegetable and field crops worldwide. In Oregon, number red clover fields contaminated with small broomrape has increased in recent years. Small parasitism is temperature related. this study, temperature-dependent relationship was developed into a predictive model based on growing degree-days (GDD) for clover. The greenhouse studies validated during three seasons. A strong between GDD parasite size...
Leaf-cover area is a widely required plant development parameter for predictive models of weed growth and competition. Its assessment performed either manually, which labor intensive, or via visual inspection, provides biased results. In contrast, digital image processing enables high level automation, thereby offering an attractive means estimating vegetative leaf-cover area. Nonetheless, image-driven analysis greatly affected by illumination conditions camera position at the time imaging...
Weed infestations in agricultural systems constitute a serious challenge to sustainability and food security worldwide. Amaranthus palmeri S. Watson (Palmer amaranth) is one of the most noxious weeds causing significant yield reductions various crops. The ability estimate seed viability herbicide susceptibility key factor development long-term management strategy, particularly since misuse herbicides driving evolution response weed species. limitations studies are that they conducted...
RNA silencing refers to diverse mechanisms that control gene expression at transcriptional and post-transcriptional levels which can also be used in parasitic pathogens of plants Broomrapes (Orobanche/Phelipanche spp.) are holoparasitic subsist on the roots a variety agricultural crops cause severe negative effects yield quality those crops. Effective methods for controlling weeds scarce, with only few known cases genetic resistance. In current study, we suggest an improved strategy based...
Summary Seed‐attacking microorganisms have an undefined potential for management of the weed seedbank, either directly through inundative inoculation soils with effective pathogenic strains, or indirectly by managing in a manner that promotes native seed‐decaying microorganisms. However, research this area is still limited and not consistently successful because technological limitations identifying pathogens involved their efficacy. We suggest these can now be overcome application new...
Understanding the spectral characteristics of crops in response to stress caused by weeds is a basic step improving precision agricultural technologies that manage field. This research focused on competition between corn (Zea mays) and redroot pigweed (Amaranthus retroflexus), common weed strongly reduces yield. The aim this was characterize physiological changes occur during early growth because crop–weed examine ability detect effect through hyperspectral measurements. A greenhouse...
Abstract Increased demand for pesticide‐free food and the development of herbicide‐resistant weed populations have created a need non‐chemical weed‐control tools. A candidate mechanical tool controlling weeds in seeding line (intra‐row zone) is finger weeder. This study thus aimed to evaluate safety efficacy weeder various irrigated field crops. Eight trials were conducted processing tomato, sweet corn, sunflower, cotton, beetroot over 2 years. The treatments applied as sole method (single...
