Introduction
I am focused on increasing our understanding of the plant microbiome. I am specifically interested in how indigenous microbiota influence host phenology, inter-microbiome interactions, and plant health. See more here: www.nicholeginnan.com

Article
Full-text available
Plant microbiomes are critical components to plant health and can influence disease outcomes. We provide empirical data describing disease-induced shifts within the citrus microbiome at different levels of Huanglongbing (HLB) disease severity. HLB is associated with an invasive phloem-limited bacterium, Candidatus Liberibacter asiaticus (CLas), tha...
Article
Full-text available
The benefits of arbuscular mycorrhizal fungi (AMF) to agroecosystems have been well recognized. Citrus is a globally grown fruit tree commonly found in association with AMF. Global citrus production is currently under the threat of the pandemic huanglongbing (HLB) disease. Since its introduction in the United States, the disease has devastated the...
Article
Full-text available
Research at the forefront of plant microbiome studies indicates that plant-associated microbes can alter the timing of plant development (phenology). However, it is unclear if host phenological stage affects microbial community assembly.

Arbuscular mycorrhizal fungi (AMF) remain understudied in perennial cropping systems. Citrus is a globally grown fruit tree and under threat by the pandemic Huanglongbing (HLB) disease. Here, we assessed in what capacity geographical location, management strategies and disease affect AMF citrus root communities. Root samples were collected from 88...

Full-text available
Emerging research indicates that plant-associated microbes can alter plant developmental timing. However, it is unclear if host phenology impacts microbial community assembly. Microbiome studies in annuals or deciduous perennial plants face challenges in separating effects of tissue age from phenological driven effects on the microbiome. In contras...
Article
Full-text available
Plant development and the timing of developmental events (phenology) are tightly coupled with plant fitness. A variety of internal and external factors determine the timing and fitness consequences of these life-history transitions. Microbes interact with plants throughout their life history and impact host phenology. This review summarizes current...

Article
Full-text available
Globally, citrus is threatened by huanglongbing (HLB), and the lack of effective control measures is a major concern of farmers, markets, and consumers. There is compelling evidence that plant health is a function of the activities of the plant's associated microbiome. Using Liberibacter crescens , a culturable surrogate for the unculturable HLB-as...
Article
Full-text available
Citrus production throughout the world is being severely threatened by Huanglongbing (HLB), which is a disease associated with the bacteria ‘Candidatus Liberibacter asiaticus’ (CLas), africanus, and americanus. This Resource Announcement provides amplicon-based next generation sequencing (NGS) datasets of the bacterial and fungal rRNA internal tran...
Article
Toe clipping is commonly used to identify individual frogs in mark–recapture studies. However, Institutional Animal Care and Use Committees (IACUCs) often have reservations about approving studies that include toe clipping as a way to mark animals. Previous studies indicate that recapture rates of terrestrial frogs and toads decrease with increasin...
