The endophytic bacterium Pseudomonas poae RE*1-1-14 shows broad antagonistic activity and is applied to seeds as a biocontrol agent to suppress late root rot in the sugar beet. The completely sequenced 5.5-Mb genome reveals genes that putatively contribute to this antagonistic activity and the intimate plant-microbe interaction.

One of the diseases that has greatest negative effect on peach production is brown rot, produced by fungus, Monilinia spp. The way to diminish this disease selection genotypes with a high tolerance while maintaining fruit quality. In study, laxa and agronomic biochemical characteristics forty-two hybrids derived from ‘Andross’ × ‘Calante’ cross were studied under controlled conditions during tw...

Isolates of Colletotrichum acutatum were collected from anthracnose-affected strawberry, leatherleaf fern, and Key lime; ripe-rot-affected blueberry; and postbloom fruit drop (PFD)-affected sweet orange in Florida. Additional isolates from ripe-rot-affected blueberry were collected from Georgia and North Carolina and from anthracnose-affected leatherleaf fern in Costa Rica. Pathogenicity tests ...

The endophytic bacterium Pseudomonas aurantiaca PB-St2 exhibits antifungal activity and represents a biocontrol agent to suppress red rot disease of sugar cane. Here, we report the completely sequenced 6.6-Mb genome of P. aurantiaca PB-St2. The sequence contains a repertoire of biosynthetic genes for secondary metabolites that putatively contribute to its antagonistic activity and its plant-mic...

In recent years, safer methods for the control of fruit postharvest pathogens have been investigated and heat treatment could represent an effective and safe approach for managing postharvest decay such as Monilinia rots. In the present study, the effect of hot water treatment (HWT) (60◦C for 30 and 60 s) on brown rot was investigated. More specifically, the influence of HWT was determined in i...

In discussion related to the planning of the present workshop on 'disease resistance in fruit', the question arose as to whether fruit harvested from stressed plants have increased, decreased, or unchanged susceptibility to pathogens whose disease symptoms are expressed after harvest. For example, does preharvest water deficit stress affect the incidence and severity of stem-end rot (endophytic...

BACKGROUND Oregano essential oil (EO) was incorporated into film-forming dispersions (FFDs) based on biopolymers (chitosan and/or methylcellulose) at two different concentrations. The effect of the application of the FFDs was evaluated on tomato plants (cultivar Micro-Tom) at three different stages of development, and on pre-harvest and postharvest applications on tomato fruit. RESULTS The ap...
