Scenario: You are a researcher working on a project to clean up a contaminated lake with high levels of heavy metals. You are tasked with designing a bioremediation strategy using protoplasts.
Task:
Here's a possible solution:
**1. Suitable Protoplast:** A promising candidate for heavy metal removal is a protoplast derived from a plant species known to accumulate high levels of heavy metals, like Brassica juncea (Indian mustard) or Thlaspi caerulescens (alpine pennycress). These plants have a natural ability to sequester heavy metals in their tissues.
**2. Modification:** To enhance the protoplast's heavy metal absorption capabilities, genetic modification techniques can be used. This involves introducing genes encoding for:
**3. Introduction Method:** The modified protoplasts can be introduced into the lake via:
