Genetic dwarfness in plants can be resolved by

Options

A. Lower ABA contents
B. Higher endogenous auxin contents
C. Higher endogenous gibberellins contents
D. High ethylene content

Answer

To resolve genetic dwarfness in plants, we need to understand the role of concavalin A, which is a type of lectin. Here’s a step-by-step solution to the question:

### Step 1: Identify the Problem
Genetic dwarfness in plants is often caused by genetic factors that inhibit normal growth.

**Hint:** Consider what substances can influence plant growth and development.

### Step 2: Understand Concavalin A
Concavalin A is a type of lectin, which is a protein that can bind to carbohydrates. It is derived from the jack bean and is known for its ability to agglutinate (clump together) cells, particularly red blood cells.

**Hint:** Lectins can interact with specific carbohydrates on cell surfaces; think about how this might affect plant cells.

### Step 3: Role of Lectins in Plant Growth
Lectins like concavalin A can play a role in signaling pathways and can influence plant growth and development. They may help in overcoming certain genetic limitations by promoting cell division and elongation.

**Hint:** Consider how signaling molecules can affect growth patterns in plants.

### Step 4: Conclusion
To resolve genetic dwarfness, applying concavalin A may help stimulate growth processes that are otherwise inhibited by genetic factors. Therefore, using concavalin A can be an effective method to address genetic dwarfness in plants.

**Hint:** Look for ways that external compounds can influence genetic traits in organisms.

### Final Answer
Genetic dwarfness in plants can be resolved by using concavalin A, which is a type of lectin that can promote growth by influencing cell signaling and division.
