What is a common effect of systemic infection in seedlings affected by bacterial wilt?

• A. Reduction in height
• B. Wilting and drought-like appearance
• C. Leaf curling
• D. Root rot

Answer: (B)

In seedlings affected by bacterial wilt, a common effect is wilting and a drought-like appearance. This occurs because the bacteria infect the vascular system, disrupting the plant's ability to transport water and nutrients effectively. As a result, even when there is sufficient water in the soil, the plant cannot take it up, leading to wilting. The symptoms manifest as drooping leaves and stems, which make the plant look as if it is suffering from drought, even in well-watered conditions.

This characteristic response is crucial for identifying bacterial wilt, as it distinguishes it from other conditions that may cause similar symptoms.
