Soft Rot of Citrus Fruit Caused by Penicillium Digitatuaa and P. Italicuaa1
Peel tissue of citrus fruit rotted by Penicillium digitatum Sacc. and P. italicum Wehmer was similar in degree of softness and relative water content. Pectolytic enzymes produced by these fungi degraded pectin of the cell wall middle lamella resulting in loss of cell coherence. This pro cess is considered important in aiding hyphal penetration. Rate of development of the decay was not determine...
متن کاملEffect of LED Blue Light on Penicillium digitatum and Penicillium italicum Strains.
Studies on the antimicrobial properties of light have considerably increased due in part to the development of resistance to actual control methods. This study investigates the potential of light-emitting diodes (LED) blue light for controlling Penicillium digitatum and Penicillium italicum. These fungi are the most devastating postharvest pathogens of citrus fruit and cause important losses du...
متن کاملTranscriptional response of Citrus aurantifolia to infection by Citrus tristeza virus.
Changes in gene expression of Mexican lime plants in response to infection with a severe (T305) or a mild (T385) isolate of Citrus tristeza virus (CTV) were analyzed using a cDNA microarray containing 12,672 probes to 6875 different citrus genes. Statistically significant (P<0.01) expression changes of 334 genes were detected in response to infection with isolate T305, whereas infection with T3...
متن کاملEffect of Pomegranate Peel Extract on Green (Penicillium digitaum) and Blue Molds (P. italicum) of Mandarin Fruit
The global trend has shifted towards the reduction of synthetic pesticide application in agriculture in general and in postharvest in particular. Currently there is a growing interest in using natural antifungal compounds, like plant extracts for the preservation of foods. In order to develop fungicide formulation of natural origin as postharvest treatments, this study was conducted on the anti...
متن کاملRelationship Between Host Acidification and Virulence of Penicillium spp. on Apple and Citrus Fruit.
ABSTRACT Penicillium expansum, P. digitatum, and P. italicum acidify the ambient environments of apple and citrus fruit during decay development. They use two mechanisms for this: the production of organic acids, mainly citric and gluconic, and NH(4)(+) utilization associated with H(+) efflux. Exposure of P. expansum and P. digitatum hyphae to pH 5.0 increased their citric acid production, comp...
