Cryptic species present challenges across many subdisciplines of biology. Not all “cryptic” species, however, are truly cryptic; simply underexplored morphologically. We examined this idea for the Antistrophus rufus complex, which previously contained three thought to be morphologically cryptic. To determine whether A. complex cryptic we assessed boundaries members using morphological, ecological, and DNA barcode data, tested a set 50 morphological characters could adequately diagnose these...

Crop rotations in the Midwest U.S. have become less diversified over last twenty years while at same time cover crop acreage has increased. The impact of these changes on soil health and microbial communities is not entirely understood. In rotational plots two sites Ohio, we investigated a corn-soy-wheat rotation rye carbon, nitrogen, organic matter, their relationships with soybean yield. Rhizosphere fungal, arbuscular mycorrhizal bacterial were also assessed, as well yield parameters....

Maize chlorotic mottle virus (MCMV) has driven the emergence of maize lethal necrosis worldwide, where it threatens production in areas East Africa, South America, and Asia. It is thought that MCMV transmission through seed may be important for introduction new regions. Identification infested lots critical preventing spread seed. Although methods detecting leaf tissue are available, diagnostic its detection lacking. In this study, ELISA, RT-PCR, RT-qPCR were adapted Purified virions...

Maize lethal necrosis is a destructive virus disease of maize caused by chlorotic mottle (MCMV) in combination with the family Potyviridae . Emergence MLN typically associated introduction MCMV or its vectors and understanding spread through seed critical for management. Previous studies suggest that although detected on seed, transmission rate this low. However, mechanisms influencing are poorly understood. Elucidating these crucial informing strategies to prevent contaminated seed. In...

Crop rotation is a cultural practice in disease management used to break the cycle, resulting reduction of inoculum. In Ohio, crop rotations have been reduced diversity, with many farmers shifting corn-soy from more diverse featuring wheat. We investigated impact this shift on soil fungal communities under corn by conducting synthetic long-read amplicon sequencing. DNA was extracted sampled during corn-growing season at two locations Ohio replicated long-term plots corn–soybean (CS) and...

Abstract Farmers are becoming interested in management practices that mitigate greenhouse gas emissions because of C trading initiatives. For example, farmers may be paid for no‐tillage and use cover crops, including winter wheat ( Triticum aestivum L.). In 2012, a study was initiated at two locations Ohio comparing corn Zea mays L.)–soybean [ Glycine max (L.) Merr.] (CS) corn–soybean–wheat (CSW) annual rotations under with no straw removal. The objectives were to compare: (a) plant stand...

Abstract Hydroponics is a method of growing plants using nutrient-enriched solution in controlled environment. Unlike soil-based systems, where soil acts as the primary source microbial inoculum, hydroponic systems rely on nutrient composition and environment conditions to influence growth, survival, dynamics. Few studies have evaluated occurrence bacteria root zone hydroponically grown crops, however fungal communities not been deeply described. This research aimed characterize diversity...

Unlike soil-based systems, where soil acts as the primary source microbial inoculum, hydroponic systems rely on nutrient composition and environment conditions to influence growth, survival, dynamics.

Crop rotation is a cultural practice in disease management used to break the cycle resulting reduction of inoculum. In Ohio, crop rotations have been reduced diversity, with many farmers shifting corn-soy from more diverse featuring wheat and forage crops. We investigated impact this shift on soil fungal communities under corn by conducting synthetic long-read amplicon sequencing.
