Description and Significance
Citrus psorosis virus (CpsV) is considered to be the most infectious and problematic virus pathogen of citrus plants worldwide, mostly in citrus producing countries such as North, South American and the Mediterranean. CpsV is the oldest reported citrus virus, first reported symptoms in 1896 and known viral etiology in 1933. There are a variety of different strains and symptoms which vary from mild, type 'A,' to severe, type 'B.' Symptoms can be exhibited in leaves, fruit, bark, trunk and branches. Leaf infection displays chlorotic flecks, or a decrease in chlorophyll/healthy coloring, mottling and spots; fruit may show ring-like chlorotic areas[1]. Chlorosis decreases plant's efficiency to perform photosynthesis, or ability to produce carbohydrates necessary for energy, organism support and growth[1]. The most common symptom of psorosis is deterioration of bark, such as flaking or scaling on trunk and limbs. Early stages of this deterioration are marked by blisters or bubbles which grow and later result in patches.
Citrus plants which have been reported to exhibit this virus are grapefuit, mandarin, orange and tangerine, lemon, pomelo and lime. It is economically important in the production and distribution of citrus fruit.
