Citrus Tristeza – Banana Sigatoka disease

Combating the Sigatoka Disease Complex on Banana

Banana is the fourth most important staple food in the world, behind rice, wheat, and maize, with more than 100 million tons produced annually [1]. Although the majority of bananas produced are consumed locally, banana export is a multi-billion–dollar business [2]. Bananas are grown in more than 100 countries worldwide, largely in developing countries in tropical regions of Africa, Asia, and La...

Citrus tristeza virus-host interactions

Citrus tristeza virus (CTV) is a phloem-limited virus whose natural host range is restricted to citrus and related species. Although the virus has killed millions of trees, almost destroying whole industries, and continually limits production in many citrus growing areas, most isolates are mild or symptomless in most of their host range. There is little understanding of how the virus causes sev...

The Complex Genetics of Citrus tristeza virus

The 2000 x 11 nm long bipolar flexuous filamentous particles of Citrus tristeza virus (CTV) (genus Closterovirus, family Closteroviridae) (Figure 1) contain a single-stranded positive-sense RNA genome of 19.3 kb, which is encapsidated in two different capsid proteins that coat the opposite ends of the virions [1, 2]. CTV is the largest identified RNA virus infecting plants and the second larges...
