Disaster plant pathology addresses how natural and human-driven disasters impact diseases the requirements for smart management solutions. Local to global drivers of disease change in response disasters, often creating environments more conducive disease. Most have indirect effects on health through factors such as disrupted supply chains damaged infrastructure. There is also potential direct from pathogen or vector dispersal due floods, hurricanes, human migration driven by war. Pulse...
Natural and human-driven disasters are a significant challenge to the sustainable production of food security crops in Great Lakes region Africa. A relevant research gap is effect climate change on distribution pathogens pests this region. We evaluated current geographic risk four - banana, cassava, potato, sweetpotato region, potential future under change. First, cropland connectivity analysis identified locations likely important spread establishment crop-specific for each crop, with...
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....

Abstract Plant litter can alter ecosystems and promote plant invasions by altering resource availability, depositing phytotoxins, transmitting microorganisms to living plants. Transmission of from invasive live plants may gain importance as plants, which often escape pathogens upon introduction a new range, acquire over time. It is unclear, however, if affects native communities promoting disease. Microstegium vimineum an grass that suppresses populations, in part through production, has...
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...
Guinea grass is an invasive perennial C4 and a common weed around agricultural crops in Louisiana, Texas, Hawaii, USA (Overholt Franck 2019). In November 2018, leaf spots were observed on occurring organic garden located Gainesville, Florida, USA. Lesions oblong to irregular, dark grey brownish center with pale-yellow black margin. had coalesced, forming necrotic margins that spread from the tip, resulting blight collapse of canopy. Pieces symptomatic blades (5 sq cm) surface sterilized (1...
Infectious diseases and invasive species can be strong drivers of biological systems that may interact to shift plant community composition. For example, disease modify resource competition between native species. Invasive tend with a diversity species, it is unclear how differ in response disease-mediated Here, we quantified the biomass responses three North American grass (Dichanthelium clandestinum, Elymus virginicus, Eragrostis spectabilis) non-native Microstegium vimineum. The foliar...
The collective participation in Belt and Road Initiative expects to forego unequal integration start inclusive fair development. Nepal also participates this initiative with similar aspirations. China has linked her West Development Strategy BRI. Nepal’s connectivity is now through Western the autonomous region of Tibet, which comes form bilateral cooperation. What kind will give best economic benefits Nepal? As an answer question, paper proposes argues for two distinct features: Regionality...
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...
Abstract Infectious diseases and invasive species are strong drivers of biological systems that may interact to shift plant community composition. Disease invasion can each directly suppress native populations, but variation in responses among disease, invasion, their combined effects not well characterized. Here, we quantified the three North American grass experimental inoculation with fungal pathogen Bipolaris gigantea , which has recently emerged populations Microstegium vimineum causing...
The interpretations of MCC in the Nepali “bazaar” comprise three themes: sovereignty, geopolitics, and governance. This study reveals that these diverging MCC, based upon themes, pose implications to national security Nepal. Firstly, it poses a challenge unity Nepalese people. Second, composed narratives United States against China under geopolitical theme construct another conduct Nepal’s foreign policy. Last, absence on economic development perspectives creates socio-economic related...
Watermelon is an important crop in Florida, representing $88.2 million cash receipts 2015 (USDA/NASS 2017). In April and May 2021, the UF/IFAS Plant Diagnostic Center Gainesville, Florida received eight diseased watermelon leaf samples from Alachua, Gilcrest, Levy, Suwannee counties Florida. Lesions were round to oblong, light gray tan with reddish brown margins white center, some coalescing resulting about 15% disease severity. Symptomatic tissue (0.5 cm2) was surface sterilized 0.6% sodium...
Abstract Plant litter can alter ecosystems and promote plant invasions by changing resource acquisition, depositing toxins, transmitting microorganisms to living plants. Transmission of from invasive live plants may gain importance as accumulate pathogens over time since introduction. It is unclear, however, if affects native communities promoting disease. Microstegium vimineum an grass that suppresses populations, in part through production, has accumulated leaf spot diseases its...
