We aimed to isolate and identify yeasts found in the tomato fruit in order to obtain isolates with biotechnological potential, such as in control of fungal diseases that damage postharvest fruits. We identified Candida orthopsilosis strains LT18 and LT24. This is the first report of this yeast on Lycopersicum esculentum fruits in Brazil.

Fungal wilt diseases are among the most destructive pathogens attacking crop plants globally. Host resistance is considered a key for Fusarium wilt management. Some resistant plant varieties have been screened, but the underlying mechanisms are poorly understood. Here detailed metabolomic analysis was performed of resistant and susceptible tomato varieties in response to Fusarium wilt infection...

Tomato (Lycopersicon esculentum Mill.) is the second most important fruit crop worldwide. Tomatoes are a key component in the Mediterranean diet, which is strongly associated with a reduced risk of chronic degenerative diseases. In this work, we use a combination of mass spectrometry (MS) techniques with negative ion detection, liquid chromatography/electrospray ionization linear ion trap quadr...

Ethylene evolution occurs concomitantly with the progression of disease symptoms in response to many virulent pathogen infections in plants. A tomato mutant impaired in ethylene perception-Never ripe-exhibited a significant reduction in disease symptoms in comparison to the wild type after inoculations of both genotypes with virulent bacterial (Xanthomonas campestris pv vesicatoria and Pseudomo...

Serum lycopene is inversely related to the risk for cancer and cardiovascular diseases. We used data from the Third National Health and Nutrition Examination Survey, 1988-1994, to investigate the relation between serum lycopene concentrations and sex, age, geographical location, race-ethnicity, education, alcohol, smoking, BMI, blood pressure, serum total cholesterol and triacylglycerol, and in...

Genetic variability due to host plants was studied in whitefly, Bemisia tabaci (Genn.), populations that were collected from fields of different crops (cotton, brinjal, potato, tomato and soyabean) and a weed (Sida sp.), and maintained on their respective host plants for 12 generations. Comparative RAPD-PCR analysis of these populations led to identification of 85 different polymorphic bands or...

The coat protein (CP) gene-containing circular DNA molecule of an isolate of tomato leaf curl geminivirus (ITmLCV; 2749 nt) obtained from southern India, and the CP genes of tomato yellow leaf curl geminivirus isolates from Nigeria and two regions of Saudia Arabia were sequenced. ITmLCV DNA had the same arrangement of ORFs, and the same pattern of repeats in the large intergenic region as is fo...

L-ascorbate (the reduced form of vitamin C) participates in diverse biological processes including pathogen defence mechanisms, and the modulation of plant growth and morphology, and also acts as an enzyme cofactor and redox status indicator. One of its chief biological functions is as an antioxidant. L-ascorbate intake has been implicated in the prevention/alleviation of varied human ailments ...

Interactions among the four biotic agents - host plants, a virus, insect vector whiteflies and their bacterial endosymbionts was investigated in this study. The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is an important crop pest that infected by several endosymbiotic bacteria can play varying roles on hosts. Both are affected plants they feed on, which turn affect fourth agen...
