Potential Biological Control Agents For Nassella Neesiana (Poaceae) Invading Australian Native Grasslands, F. E. Anderson, M. L. Díaz, D. A. Mclaren
IGC Proceedings (1997-2023)
The introduction and proliferation of exotic stipoid grasses over the past 100 years seriously threatens agricultural productivity and the integrity of Australia's indigenous flora and fauna, particularly its grasslands (McLaren et al., 1998). The full effect on biodiversity by the spread of these grasses is unknown but likely to be major (Hocking, 1998). Conventional control techniques have not stopped the invasion adequately, so it is a priority to find control options to achieve an effective management strategy. A biological control project against Nassella trichotoma and N. neesiana was initiated in 1999 in Argentina. We report on the most recent …

The "psilocybiome" represents the mutually beneficial relationship between ourselves, our bacteria, and psychedelic drugs. This short review briefly discusses the benefits and limitations surrounding the potential for psychedelic therapy to synergize with gut bacteria to help regulate and maintain proper balance in the immune system, diet, and stress levels. Psychedelic therapy is a novel treatment strategy that has the potential to improve patient mental health, and, by identifying the types of gut bacteria present in patients, it can aid in personalizing medicine by determining how well their "psilocybiome" may respond.

In recent times, land use in the United Kingdom has undergone considerable changes because of social and economic pressures, leading to a fine balance between the demands of highly productive intensive systems and practices which are perceived to be more environmentally acceptable. Plant productivity is governed by the supply of nutrients from the soil, which in turn is dependent on the dynamics of organic matter decomposition driven by soil micro-, meso- and macro fauna. Considerable information is available concerning the impact of inorganic fertiliser additions on communities of macro-fauna and flora, but the effects on specific microbial communities in soils …

Possibilities To Avoid Growth Of Clostridia And/Or Fungi In Wilted Silage By Use Of Organic And Inorganic Salts, Martin Knický, P. Lingvall
IGC Proceedings (1997-2023)
The hygienic quality of silage will be of great importance in the future as poor quality not only influences the animal production but also the animal health and the food quality. This study examined the impact of mixtures of sodium benzoate (NaB), sodium nitrite (NaN), hexamine (HMTA), sodium propionate (NaP), sodium bisulphite, and propionic acid on low and high wilted clover/grass. The silage (crop wilted to 300 or 600 g DM kg-1 of fresh weight) consisted of about 50% red clover (Trifolium pratense) and 50% timothy (Phleum pratense) and the study covered 7 additive treatments. …

Indigenous Traditional knowledge (ITK) is the local knowledge unique to a given culture or society. It is the basis for local-level decision making in agriculture, health care, food preparation, natural-resource management and a host of other activities in rural communities. Storage structures and locally available plant products were used to store seeds and to ward off seed pests and pathogens. In different parts of India, different types of containers are used locally to store different crop seeds, according to the availability and climatic conditions. Sundaramari et. al. (2011) advocated the importance of indigenous storage structures for safe storage of grains …

Fungi growth occurs in seeds as a result of environmental conditions (high relative humidity, suitable temperature and high level of seed moisture content). But pathogen free healthy seeds are required for plant propagation. Microbial and insect attack affect seeds throughout the life cycle of the plant (Islam et al., 2009). Fungi are the most common microbes that affect seed germination and they can be both saprophytic and pathogenic. Hence, the aim of this experiment is to determine the cultural and morphological characteristics and population of fungi associated with the germination of some legume seeds after storage and scarification.

Perennial peanut has high quality, evidenced by the improvement of animal production in grazing, due to good contents of crude protein and digestibility, which makes it one of the best alternatives for low cost feeding (Paganella and Valls 2002). Grass ensilage associated with legumes is considered an alternative to meet the protein demand of cattle in the livestock. However, due to limited information on the techniques of grass ensilage with tropical legumes, this research aimed to evaluate the chemical composition and the fermentation profile of perennial peanut and Marandu mixed grass silages, treated or not with bacterial inoculant.

Swainsonine—a cytotoxic fungal alkaloid and a potential cancer therapy drug—is produced by the insect pathogen and plant symbiont Metarhizium robertsii, the clover pathogen Slafractonia leguminicola, locoweed symbionts belonging to Alternaria sect. Undifilum, and a recently discovered morning glory symbiont belonging to order Chaetothyriales. Genome sequence analyses revealed that these fungi share orthologous gene clusters, designated “SWN,” which included a multifunctional swnKgene comprising predicted adenylylation and acyltransferase domains with their associated thiolation domains, a β-ketoacyl synthase domain, and two reductase domains. The role of swnK was demonstrated by inactivating it in M. robertsii through homologous …

Seed germination and seedling establishment are central to the distribution and abundance of plant species in wetlands. While fungal and oomycete pathogens are known to affect seed viability and emergence, relatively little is known about which fungi and oomycetes are associated with seeds in the soil or how these species affect seeds and seedlings. We characterized the fungi and oomycetes associated with overwintering seeds in wetlands and determined their potential to influence seed germination and subsequent seedling mortality. Fungi and oomycetes did not affect seed germination, despite the isolation of high frequencies of known seed and seedling pathogens in the …

Plants that accumulate the yeast polyadenylate binding protein (yPAB) display a range of abnormalities, including a characteristic chlorosis in leaves to a necrosis and pronounced inhibition of growth. The severity of these abnormalities reflects the levels of yeast PAB expression in the transgenic plants. In contrast, no obvious differences are seen in undifferentiated callus cultures that express the same range of yeast PAB. The expression of the yeast PAB1 gene in plants does not affect expression of the plant PAB gene family or alter poly(A) length in the total RNA population. It is proposed that the yeast PAB1 gene or …
