LibertyLink

LibertyLink is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand LibertyLink rather than just read about it. In short: LibertyLink is a BASF-owned brand of genes for use in agriculture providing tolerance to Liberty herbicide and glufosinate (a.k.a. Liberty or Basta).

Key takeaways

LibertyLink belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect LibertyLink to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of LibertyLink from memory before moving on to harder problems.

Reference excerpt

LibertyLink is a BASF-owned brand of genes for use in agriculture providing tolerance to Liberty herbicide and glufosinate (a.k.a. Liberty or Basta). The genes were developed by Bayer CropScience, before being sold to BASF Ag in late 2017. LibertyLink provides an herbicide resistance system that is still effective in the presence of glyphosate resistant weeds. The gene which gives resistance to glufosinate is a bar or pat gene which was first isolated from two species of Streptomyces bacteria. Glufosinate was included in a biocide ban proposed by the Swedish Chemicals Agency and approved by the European Parliament on January 13, 2009.

Crops The LibertyLink gene is available in a variety of crops including corn, cotton, canola, sugarbeet and soybean. It is not available in rice.

Contamination lawsuit In 2006, the U.S. Department of Agriculture announced that Bayer CropScience's LibertyLink genetically modified rice had contaminated the U.S. rice supply. Shortly after the public learned of the contamination, the E.U. banned imports of U.S. long-grain rice and the futures price plunged. In April 2010, a Lonoke County, Arkansas jury awarded a dozen farmers $48 million. The case was appealed to the Arkansas Supreme Court, which affirmed the judgement. On 1 July 2011, Bayer CropScience agreed to a global settlement for up to $750 million.

Worked examples

Example 1 — a first encounter with LibertyLink

Start with the simplest possible case. Write down what LibertyLink claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to LibertyLink before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about LibertyLink ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of LibertyLink

In research: LibertyLink appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses LibertyLink in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: LibertyLink is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agriculture stubs, Chemical companies of Germany, Genetically modified organisms in agriculture, so understanding it makes those chapters shorter.
In everyday life: Look for LibertyLink outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is LibertyLink in simple terms?

LibertyLink is a BASF-owned brand of genes for use in agriculture providing tolerance to Liberty herbicide and glufosinate (a.k.a. Liberty or Basta).

Why does LibertyLink matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study LibertyLink?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on LibertyLink.
