A species of gram-negative bacteria, in the genus XANTHOMONAS, causing disease in TOMATO and pepper crops.

A genus in the family XANTHOMONADACEAE whose cells produce a yellow pigment (Gr. xanthos - yellow). It is pathogenic to plants.

A species of gram-negative, aerobic bacteria that is pathogenic for plants.

A plant genus of the family SOLANACEAE. The hot peppers yield CAPSAICIN, which activates VANILLOID RECEPTORS. Several varieties have sweet or pungent edible fruits that are used as vegetables when fresh and spices when the pods are dried.

A species of gram-negative bacteria in the genus XANTHOMONAS, which causes citrus cankers and black rot in plants.

Diseases of plants.

A plant species of the family SOLANACEAE, native of South America, widely cultivated for their edible, fleshy, usually red fruit.

Expanded structures, usually green, of vascular plants, characteristically consisting of a bladelike expansion attached to a stem, and functioning as the principal organ of photosynthesis and transpiration. (American Heritage Dictionary, 2d ed)

Proteins found in any species of bacterium.

A plant family of the order Solanales, subclass Asteridae. Among the most important are POTATOES; TOMATOES; CAPSICUM (green and red peppers); TOBACCO; and BELLADONNA.

A family of flowering plants in the order Piperales best known for the black pepper widely used in SPICES, and for KAVA and Betel used for neuroactive properties.

A genus of gram-negative, facultatively anaerobic, small, rod-shaped bacteria occurring in fresh water.

The degree of pathogenicity within a group or species of microorganisms or viruses as indicated by case fatality rates and/or the ability of the organism to invade the tissues of the host. The pathogenic capacity of an organism is determined by its VIRULENCE FACTORS.
