A cationic lipid mediated CRISPR/Cas9 technique for the production of stable genome edited citrus plants

Plant Methods, 2022
Background The genetic engineering of crops has enhanced productivity in the face of climate change and a growing global population by conferring desirable genetic traits, including the enhancement of biotic and abiotic stress tolerance, to improve ...

Identification and Characterization of Two Putative Citrus Phosphomannose Isomerase (CsPMI) Genes as Selectable Markers for Mature Citrus Transformation

Horticulturae, 2022
Two Citrus sinensis (L.) phosphomannose isomerase (PMI) genes, CsPMI1 and CsPMI2, were evaluated as novel selectable markers in mature citrus transformation.

Canopy Density, but Not Bacterial Titers, Predicts Fruit Yield in Huanglongbing-Affected Sweet Orange Trees

Plants, 2023
In Florida, almost all citrus trees are affected with Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus (CLas). We characterized various parameters of HLB-affected sweet orange trees in response to yield-improving nutritional treatment ...

A new toolset for protein expression and subcellular localization studies in citrus and its application to citrus tristeza virus proteins

Plant Methods, 2018
Background Transient gene expression is a powerful tool to study gene function in plants. In citrus, Agrobacterium transformation is the method of choice for transient expression studies, but this method does not work efficiently with many gene ...

Effects of δ‐aminolevulinic acid dehydratase silencing on the primary and secondary metabolisms of citrus

Plant Direct, 2018
δ‐aminolevulinic acid dehydratase (ALAD) is an important enzyme in tetrapyrrole synthesis. ALAD combines two δ‐aminolevulinic acid (δ‐ALA) molecules to form the pyrrole molecule, porphobilinogen, an important precursor for plant pigments involved in ...

An insect virus differentially alters gene expression among life stages of an insect vector and enhances bacterial phytopathogen transmission

Journal of Virology
Diaphorina citri transmits Candidatus Liberibacter asiaticus (CLas) between citrus plants which causes the expression of huanglongbing disease in citrus. D. citri flavi-like virus (DcFLV) co-occurs intracellularly with CLas in D. citri populations in the

Voluntary Collective Action to Address Growing Agricultural Challenges in Two Countries: Experimental Insights and Commonalities

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We conducted two framed field economic experiments with citrus farmers in Florida, United States and soybean farmers in Argentina to investigate their willingness to coordinate pest and weed management efforts. Despite the contrast between these two agricultural contexts, we find striking behavioral commonalities.

How cold is too cold? A theoretical analysis of the optimal trigger for index insurance for frost damage to crops

American Journal of Agricultural Economics, EarlyView.
Abstract Crop insurance is undoubtedly an extremely valuable element in protecting agricultural businesses, but in many cases standard indemnity‐based products have had very low uptake due to high transaction costs elevating premiums to unaffordable levels.

Phloem Regeneration Is a Mechanism for Huanglongbing-Tolerance of “Bearss” Lemon and “LB8-9” Sugar Belle® Mandarin

Frontiers in Plant Science, 2019
Huanglongbing (HLB) is an extremely destructive and lethal disease of citrus worldwide, presumably caused by phloem-limited bacteria, Candidatus Liberibacter asiaticus (CLas).

Risk management externalities in agrifood supply chains

American Journal of Agricultural Economics, EarlyView.
Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...
