What are the symptoms of wart disease of potato?

-✅Explanation: Wart disease of potato is caused by the Synchytrium endobioticum fungus. The symptoms include the development of large, irregular, wart-like growths (tumors) on the surface of the tubers and sometimes on the roots. These growths are typically greenish or yellowish and are a characteristic feature of this disease.

📌Other Options Explanations:
-Soft rot of potato is caused by bacterial pathogens (like Pectobacterium species) and leads to a mushy, decayed appearance of the tubers.
-Black heart of potato is associated with internal rot caused by a lack of oxygen in storage conditions, leading to blackened tissue inside the tubers.

🔑Key Points:
-Synchytrium endobioticum causes the black wart or wart disease of potatoes (Solanum tuberosum).
-Usually, the disease affects the underground parts of the host.
-Diseased potato tubers appear as dark brown or black cauliflower-like outgrowths.
-Galls or tumors may be formed on aerial parts as well.
-Due to the presence of the fungus, the host cells are stimulated to divide leading to an increase in the number of host cells.
-Most of the host cells contain resting sporangia.
