WHO CAUSES IT?
Beet Mild Yellowing Virus (BMYV) is a virus that primarily affects beet plants, causing a disease known as beet mild yellowing virus. This virus belongs to the Polerovirus genus, within the Luteoviridae family. BMYV is a positive-sense single-stranded RNA virus. Its cycle begins when an aphid, the main vector, feeds on an infected plant, thus acquiring the virus. Aphids transmit the virus to new plants during feeding. Within the beet plant, BMYV replicates in phloem cells and moves through the vascular system, interfering with nutrient transport and causing the characteristic symptoms of the disease. Viral replication and spread are facilitated by proteins encoded by the virus, which contributes to the spread of the pathogen within the plant.
SYMPTOMS
The beet moderate yellowness virus produces a series of symptoms in beet plants that affect their development and yield. The first signs of the disease include slight yellowing of the leaves, which may go unnoticed in the early stages. As the infection progresses, the yellowing spreads and may intensify, affecting plant growth and productivity. Infected plants may also exhibit leaf curling and a general reduction in vigor.
- Slight yellowing of the leaves
- Extension of yellowing throughout the plant
- Leaf curling
- Reduction of plant vigor
- Decreased growth
- Lower crop yield
