| dc.description.abstract | Citrus fruit is considered a very nutritious and delicious diet. Citrus consists of
lemon, oranges, mandarin, and grapefruit which have economic value in the world.
Significant losses occur in citrus due to numerous diseases. Among various
diseases, citrus trees are seriously affected by a phytopathogenic mollicute
Spiroplasma citri which causes stubborn disease. S. citri is transovarially
transmitted by several leafhopper species. Symptoms include smaller and cupped
leaves, small size, crook fruits with aborted seeds. Moreover, irregularity on the
fruits such as different sizes, shapes, and typically lighter, smaller fruits than its
healthy counterpart has also been observed. The affected fruits often drop before
maturity. The color inversion is often seen with the stylar end remaining green and
the peduncle end showing color. Various molecular and biochemical tests are
conducted to identify S. citri. Under in-vitro conditions, S. citri grows on SP4 media
where a fried egg-like shaped colony is observed. Keeping the importance of the
stubborn citrus disease, the present short note briefly described the
symptomology, detection, transmission, and management. | en_US |
