Sweet orange scab with a new scab disease "syndrome" of citrus in the USA associated with Elsinoë australis [PDF]

Tropical Plant Pathology, 2013
Elsinoe fawcettii causes citrus scab and E. australis causes sweet orange scab and there are different pathotypes of each species. Citrus scab is widely distributed, whereas sweet orange scab is limited mostly to southern South America. In 2010, E. australis was detected by PCR in Texas for the first time in the USA and subsequently found in commercial

Development of PCR Assays for the Identification of Species and Pathotypes of Elsinoë Causing Scab on Citrus [PDF]

Plant Disease, 2007
Two scab pathogens of citrus, Elsinoë fawcettii and E. australis, cause citrus scab and sweet orange scab, respectively, and pathotypes of each species have been described. The two species cannot be readily distinguished by morphological or cultural characteristics and can be distinguished only by host range and the sequence of the internal ...

Factors Affecting the Production of Elsinochrome Phytotoxin by the Citrus Scab Pathogen, Elsinoe fawcettii [PDF]

The Open Mycology Journal, 2009
Elsinochrome (ESC), light-activated, nonhost-selective phytotoxin, is produced by many members of the genus Elsinoe and required for full virulence of the fungus. It appears that approaches disrupting the ESC production will likely reduce disease severity caused by Elsinoe pathogens. In this study, the influence of nutritional and environmental factors

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.

A co-inoculation technique to rapidly screen citrus hybrids for resistance to both Alternaria Brown Spot caused by Alternaria alternata and Citrus Scab caused by Elsinoe fawcettii.

, 2016
A simple and inexpensive technique has been developed to allow the simultaneous screening of young hybrid seedlings for susceptibility to Alternaria Brown Spot (ABS) caused by Alternaria alternata and Citrus Scab (CS) caused by Elsinoe fawcettii.

Citrus aurantium honey‐mediated gut homeostasis and anti‐inflammation via Thorl/Nprl2‐TORC1 signaling: Network pharmacology and Drosophila validation

Animal Models and Experimental Medicine, EarlyView.
The study employed a four‐tiered strategy: (1) UHPLC‐FTMS profiling of Citrus aurantium honey to characterize its chemical composition; (2) network pharmacology analysis integrating target prediction, protein–protein interaction networks, and KEGG pathway enrichment to identify the Thor1/Nprl2‐TORC1 axis as a key mechanistic pathway; (3) in vitro ...

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

Biological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

Automatic Detection of Citrus Fruit and Leaves Diseases Using Deep Neural Network Model

IEEE Access, 2021
Citrus fruit diseases are the major cause of extreme citrus fruit yield declines. As a result, designing an automated detection system for citrus plant diseases is important.
