Environmental Requirements for Germination and Appressorium Formation of Ascospores and Conidia of Phyllosticta citricarpa, the Causal Agent of Citrus Black Spot

Plant Pathology, Volume 74, Issue 7, Page 2108-2120, September 2025.
Cardinal temperatures for both Phyllosticta citricarpa spore germination were estimated as ~10ºC (minimum) and ~40ºC (maximum), and the optimum temperatures were ~30ºC for ascospores and ~24ºC for conidia. ABSTRACT Phyllosticta citricarpa produces ascospores and conidia that infect citrus tissues and cause citrus black spot (CBS).

Advancements in Water‐Saving Strategies and Crop Adaptation to Drought: A Comprehensive Review

Physiologia Plantarum, Volume 177, Issue 4, July/August 2025.
ABSTRACT Drought stress, which is one of the most critical environmental constraints affecting global crop productivity, is exacerbated by climate change and increased atmospheric water demand. This review comprehensively examines plant responses to drought, integrating physiological, morphological, biochemical, and genetic adaptations that contribute ...

A high‐throughput analysis of high‐resolution X‐ray CT images of stems of olive and citrus plants resistant and susceptible to Xylella fastidiosa

Plant Pathology, Volume 73, Issue 3, Page 630-643, April 2024.
Though morphological traits of resistant olives (narrow vessels) and citrus' (connected vessels) are distinct, across both taxa, susceptible cultivars have many more vessels; representing a potentially broader‐reaching trend. Abstract The bacterial plant pathogen Xylella fastidiosa causes disease in several globally important crops.

Genetic divergence among hybrids of 'Cravo' mandarin with 'Pêra' sweet orange

Scientia Agricola, 2003
Molecular markers have been used as tools in breading programs of sexual hybridation, allowing the genetic characterization of a large number of genotypes. The RADP markers are the most used since the employed techniques are simple and of low cost.
