Fusariosis, caused by the fungus Fusarium subglutinans f. sp. ananas (Syn. F. guttiforme), is one of the main phytosanitary threats to pineapple (Ananas comosus var. comosus). Identification of plant cell responses to pathogens is important in understanding the plant?pathogen relationship and establishing strategies to improve and select resistant cultivars. Studies of the structural properties and phenolic content of cell walls in resistant (Vitoria) and susceptible (Perola) pineapple cultivars, related to resistance to the fungus, were performed. The non-chlorophyll base of physiologically mature leaves was inoculated with a conidia suspension. Analyses were performed post-inoculation by light, atomic force, scanning and transmission electron microscopy, and measurement of cell wall-bound phenolic compounds. Non-inoculated leaves were used as controls to define the constitutive tissue characteristics. Analyses indicated that morphological differences, such as cell wall thickness, cicatrization process and lignification, were related to resistance to the pathogen. Atomic force microscopy indicated a considerable difference in the mechanical properties of the resistant and susceptible cultivars, with more structural integrity, associated with higher levels of cell wall-bound phenolics, found in the resistant cultivar. p-Coumaric and ferulic acids were shown to be the major phenolics bound to the cell walls and were found in higher amounts in the resistant cultivar. Leaves of the resistant cultivar had reduced fungal penetration and a faster and more effective cicatrization response compared to the susceptible cultivar.

1. Fertilization input is required to improve productivity and attend the market demand for tomatoes. However, providing crops with nutrients can affect plant?insect interactions via bottom-up effects. The South American tomato pinworm, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is a main pest of tomato crops worldwide but little is known about the effects of macro-elements fertilization inputs on its biological traits.
2. This study aimed to evaluate the effects of low, high and normal fertilization levels calcium, sulphur, nitrogen and potassium to tomato plants on T. absoluta development, survival and crop damage.
3. Larval mortality was lower in tomato plants fertilized with high sulphur fertilization level. The number of mines per leaf was not affected by calcium, sulphur and potassium fertilization, but low nitrogen input resulted in higher crop damage. Overall, our results indicate that nutritionally unbalanced tomato plants improve the biological performance of T. absoluta in comparison with balanced plants.
4. The results provide useful information that can be used in fertilization programmes of tomato and planning of strategies and tactics to reduce tomato suitability to T. absoluta.
5. In addition, the obtained findings provide an insight into the basic understanding of the interactions between crop fertilization and the performance T. absoluta. |
