Abstract:

Abstract To understand the role of Los1p in pre-tRNA splicing, we sought los1 multicopy suppressors. We found SOLl that suppresses both point and null LOS1 mutations. Since, when fused to the Gal4p DNA-binding domain, Los1p activates transcription, we tested whether Los1p regulates SOL1. We found that los1 mutants have depleted levels of SOL1 mRNA and Sollp. Thus, LOS1 appears to positively regulate SOL1. SOL1 belongs to a multigene family with at least two additional members, SOL2 and SOL3. Sol proteins have extensive similarity to an unusual group of glucose-6phosphate dehydrogenases. As the

Abstract:

Previous studies have shown that various Eucalyptus species can yield allelopathic chemicals which may be effective in suppressing understorey vegetation. However, the techniques employed in many studies do not resemble natural ecological processes. This study used germination of Lolium and growth of Lolium, Lemna, Eucalyptus and Acacia to test for allelopathy. Extraction techniques mimicked typical daily rainfall rates upon quantities of foliage, leaf litter and bark litter that are typically encountered in forests; root leachates were obtained hydroponically; stemflow was obtained following

Abstract:

Diseases remain a yield-limiting factor for crops despite the availability of control measures for many pathogens. Indigenous soil microorganisms can suppress some plant pathogens, yet there is little systematic information on the effects of cropping systems on disease-suppressive populations in soil. Streptomyces have been associated with suppression of plant diseases in several naturally occurring disease-suppressive soils. Pathogen-suppressive activity of Streptomyces communities is correlated with higher bacterial densities and with inhibitory phenotypes, driven by competition among indige

Abstract:

Soils suppressive to soilborne pathogens have been identified worldwide for almost 60 years and attributed mainly to suppressive or antagonistic microorganisms. Rather than identifying, testing and applying potential biocontrol agents in an inundative fashion, research into suppressive soils has attempted to understand how indigenous microbiomes can reduce disease, even in the presence of the pathogen, susceptible host, and favorable environment. Recent advances in next-generation sequencing of microbiomes have provided new tools to reexamine and further characterize the nature of these soils.

Abstract:

Cover crops are an important component of integrated weed management programs in annual and perennial cropping systems because of their weed suppressive abilities. They influence weed populations using different mechanisms of plant interaction which can be facilitative or suppressive. However, the question often arises if cover crops can be solely relied upon for weed management or not. In this review we have tried to provide examples to answer this question. The most common methods of weed suppression by an actively growing cover crop include competition for limited plant growth resources tha

In disease-suppressive soils, microbiota protect plants from root infections. Bacterial members of this microbiota have been shown to produce specific molecules that mediate this phenotype.

Here, we screened a large collection of field soils for suppressiveness to Fusarium culmorum using wheat ( Triticum aestivum ) as a model host plant. A high variation of disease suppressiveness was observed, with 14% showing a clear suppressive phenotype. The

Total DNA was extracted from both the disease-conducive and -suppressive soils. A phylogenetically taxon-informative region of the 16S rRNA gene was u

Abstract:

This study aimed to evaluate the suppressive potential of different soils on soybean cyst nematodes (SCN) and to estimate the suppressive mechanism. Fifteen soils (designated as soil A to O) from different agricultural fields with varying organic inputs were added with SCN-infested soil and grown with a green soybean variety. The SCN density in the soil at 6 weeks of soybean growth was markedly different depending on the soils used, indicating a different level of disease suppressiveness. No significant correlation was observed between the SCN density and any of the soil physicochemical and bi

A total of 12 soils collected from different agricultural fields, having different backgrounds of organic input, were evaluated for their suppressive potential against Meloidogyne incognita. Second-stage juveniles (J2) of M. incognita were inoculated into the soils and their survival was evaluated. The number of M. incognita J2 5 days after inoculation differed depending on soil and was significantly lower in two soils, suggesting higher suppressiveness against M. incognita in these soils. This was confirmed by an experiment using tomato as a test plant, in which the gall formation was signifi

Pythium spp. and Pratylenchus penetrans are significant components of the diverse pathogen complex that incites apple replant disease in Washington State.

Abstract:

The suppressors of cytokine signaling (SOCS) are a cytoplasmic protein family that completes a negative feedback loop to attenuate signal transduction from cytokines through the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway. They work as a natural precaution to pre-vent excessive immune responses that could cause collateral damage to body tissues. But viruses use SOCS proteins to suppress the proportionate immune response also so that a vulnerable environment can be developed in host body to let them grow freely.

Many studies have suggested that E3 ubiquitin ligases can behave as either oncogenes or tumour suppressor genes and, recently, it has become clear that the SOCS (suppressor of cytokine signalling) E3 ligases fit this mould. While most cancer-associated E3s regulate the cell cycle or DNA repair, the SOCS proteins inhibit growth factor responses by degrading signalling intermediates such as JAKs (Janus kinases) via the SOCS-box-associated ECS (Elongin–Cullin–SOCS) E3 ligase.

The results revealed that raising cowpea as a dual crop with maize at a spacing of 60 x 20 cm not only suppresses the weed growth but also supplies nutrient to the crop, resulting in highest grain yield, (62 q/ha) net return (Rs. 12,006/ha) and BC ratio (2.06) compared to 43.6 q/ha, Rs. 6376/- and 1.55 respectively under sole cropping of maize.

Abstract:

Fusarium wilt of spinach is caused by the soilborne fungus Fusarium oxysporum f. sp. spinaciae and occurs in most regions of spinach production. The disease is favored by acid soils and warm temperatures, and the fungus can survive extended periods as chlamydospores or by asymptomatic colonization of the roots of nonhost plant species. The 10- to 15-year rotation required to minimize losses to Fusarium wilt is the primary constraint on spinach seed production in the maritime Pacific Northwest, the only region of the United States suitable for this cool-season, daylength-sensitive crop.

Abstract:

Managing soil-borne pathogens and diseases in plants is particularly challenging because the pathogens that cause them can persist in the soil for extended periods, often resulting in repeated crop damage in affected areas. These destructive diseases compromise plant health by weakening the root systems, which makes the plants more susceptible to environmental stress and nutritional deficiencies. Every year in the United States, a whopping $9.6 million is allocated to reverse the harmful effects of pesticides on humans, plants, animals, and the environment.

These data strongly suggest that Glc7 ensures accurate chromosome segregation by dephosphorylating Ipl1 targets rather than regulating the Ipl1 kinase. To identify potential Glc7 and Ipl1 substrates, we isolated ipl1-321 d

Abstract Suppressors of cytokine signaling (SOCS) have emerged as multiple role players in the regulation of immune signaling pathways.

In the present study we have investigated the role of SOCS in ROS-mediated T cell differentiation leading to Th1/Th2 cytokine production.
