My Plant Has Galls On a Plant

What are Plant Galls?

Plant galls are abnormal growths that can occur on various parts of a plant, including leaves, stems, roots, and flowers. They are usually caused by external factors, such as insects, bacteria, fungi, or viruses, that stimulate the plant's cells to multiply and form a gall. Galls can vary in size, shape, and color, and may appear as bumps, blisters, or knots on the plant's surface.

Types of Plant Galls

There are several types of plant galls, each with its own unique characteristics and causes. Some common types of galls include:

- Insect galls: Caused by insects such as aphids, wasps, and midges, these galls can appear as small, rounded bumps or complex structures on the plant's leaves or stems.

- Bacterial galls: Caused by bacteria such as Agrobacterium tumefaciens, these galls can appear as large, tumor-like growths on the plant's stems or roots.

- Fungal galls: Caused by fungi such as Uromyces, these galls can appear as small, powdery or rusty spots on the plant's leaves.
