Small hermetic bags (50 and 100 kg capacities) used by smallholder farmers in several African countries have proven to be a low-cost solution for preventing storage losses due insects. The complexity of postharvest practices the need ideal drying conditions, especially Sub-Sahara, has led questions about efficacy controlling spoilage fungi potential mycotoxin accumulation. This study compared effects environmental temperature relative humidity at two locations (Indiana Arkansas) on dry maize...
Prior to harvest, maize kernels are invaded by a diverse population of fungal organisms that comprise the microbiome grain mass. Poor post-harvest practices and improper drying can lead growth mycotoxigenic storage fungi deterioration quality. Hermetic bags low-cost technology for preservation during storage, which has seen significant adoption in many regions Sub-Saharan Africa. This study explored use high-throughput DNA sequencing Internal Transcribed Spacer 2 (ITS2) region...
Plants in grasslands navigate a complex landscape of interactions including competition for resources and defense against pathogens. Foliar fungi can suppress plant growth directly through pathogenic interactions, or indirectly via host growth-defense tradeoffs. The exclusion foliar allows the reallocation from to reproduction. In addition, plants also invest photosynthates rhizodeposition, root exudates, which play significant role shaping rhizosphere microbial community. However, it...
Non-native invasive plants can establish in natural areas, where they be ecologically damaging and costly to manage. Like cultivated plants, experience a relatively disease-free period upon introduction accumulate pathogens over time. Diseases of plant populations are infrequently studied compared diseases agriculture, forestry, even native populations. We evaluated similarities differences the processes that likely affect pathogen accumulation disease which dominant focus field pathology....

Invasive plants, which cause substantial economic and ecological impacts, acquire both pathogens beneficial microbes in their introduced ranges. Communities of fungal endophytes are known to mediate impacts on plant fitness but few studies have examined the temporal dynamics communities invasive plants. The annual grass Microstegium vimineum, an invader forests riparian areas throughout eastern United States, experiences epidemics disease caused by Bipolaris pathogens. Our objective was...
Abstract Soil bacteria spend significant periods in dormant or semi‐dormant states that are interrupted by resource pulses which can lead to of rapid growth and intense nutrient competition. Microbial populations have evolved diverse strategies circumvent competitive interactions facilitate coexistence. Here, we show use soilborne Streptomyces is temporally partitioned during experimental pulses, leading reduced niche overlap, potential grew rapidly on the majority distinct 95 carbon sources...
Bipolaris gigantea is a pathogen of the invasive grass Microstegium vimineum and an emerging other hosts such as hemp barley, causing characteristic eyespot foliar lesions. The fungus characterized by long pale hyaline conidia measuring about 300 to 350 μm. Previously, this was classified in Drechslera genus, recently reassigned based on molecular identification. Here, we generated high-quality draft genome sequence B. isolate BGF using short read DNA sequencing. assembled genome, 30.23 Mb...
Abstract Invasive species impact ecosystems through their large abundances and strong per capita effects. Enemies can regulate effects, but are notably absent for many new invaders. However, invaders acquire enemies over time as they spread; processes hypothesized to mitigate negative invader impacts by reducing abundance or Alternatively, properties of acquired enemies, such an enemy’s ability attack multiple species, may hinder enemy mitigation impacts. We used field experiments evaluate...
