Pepper tissue necrosis

Capsicum annuum L.

Tissue necrosis in pepper is not a standalone disease, but a general symptom of infection by various bacterial, fungal, and viral pathogens, or a physiological disorder.

In the reference 4 varieties crop Bell pepper, where this is mentioned in the description.

Bacterial infections manifest as black spotting on leaves and stems, darkening of vascular bundles during wilting caused by Pseudomonas solanacearum, as well as softening and maceration of stem tissues due to Pectobacterium. Fungal and oomycete pathogens, such as Phytophthora capsici, cause extensive necrotic areas on roots and stems, while Fusarium species provoke latent necrosis of the seeds and fruit placenta.

Viral infections can lead to necrosis of the apical meristem and fruits, which is characteristic of the pepper mild mottle virus. In pepper breeding, resistance is evaluated not against the concept of "necrosis," but against specific pathogens, such as Xanthomonas vesicatoria or Phytophthora capsici, using modern methods of QTL mapping and bioinformatic analysis.
