Sensitivity to demethylation-inhibiting fungicides and induced expression of CYP51 associated with tebuconazole resistance in Alternaria species on mandarin in Brazil. [PDF]

Pest Manag Sci
Tebuconazole‐resistant isolates overexpress CYP51 and, when tested at field rates, did not reduce ABS severity, whereas difenoconazole and mefentrifluconazole remained effective. Abstract BACKGROUND Alternaria brown spot (ABS), caused by Alternaria spp., is an important disease affecting mandarin production in several citrus‐growing regions worldwide ...

Parallel host shifts in a bacterial plant pathogen suggest independent genetic solutions. [PDF]

Mol Plant Pathol, 2023
In Xylella fastidiosa, two parallel host shifts to infect olive trees occurred in Brazil and Italy, but the lack of genetic convergence in olive‐infecting strains across the two distinct clades suggests independent genetic solutions. Abstract While there are documented host shifts in many bacterial plant pathogens, the genetic foundation of host shifts

High Environmental Irradiance Induces Anatomical and Ultrastructural Damage in Citrus Leaves. [PDF]

Physiol Plant
ABSTRACT Climate change is intensifying episodes of high irradiance and thermal stress, posing a major threat to the sustainability of citrus production. Although reflective particle films have emerged as mitigation tools, their protective effects at the anatomical and ultrastructural levels under field conditions remain insufficiently understood. Here,

Reaction of Mandarins to the Alternaria Brown Spot and Huanglongbing: Identification of Potential Varieties for These Diseases to Be Managed in the Field

Horticulturae, 2023
Mandarins occupy the third group among citrus produced in Brazil. Primarily aimed at the fresh fruit market, commercial orchards have suffered significant production losses due to the high incidence of diseases, such as the alternaria brown spot (ABS ...

Strategies for Enhancing Resilience in Horticultural Crops Against Combined Abiotic Stresses. [PDF]

Physiol Plant
ABSTRACT Horticultural crops are increasingly exposed to simultaneous abiotic stresses such as drought, salinity, and temperature extremes, which often exacerbate each other's effects, leading to severe yield and quality losses. Addressing these multifaceted challenges necessitates the development and application of integrated and innovative strategies.
