Germplasm Resources Information Network

Germplasm Resources Information Network is a computer science 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 Germplasm Resources Information Network rather than just read about it. In short: Germplasm Resources Information Network or GRIN is an online USDA National Genetic Resources Program software project to comprehensively manage the computer database for the holdings of all plant germplasm collected by the National Plant Germplasm System. GRIN has extended its role to manage information on the germplasm reposits of insect (invertebrate), microbial, and animal species (see sub-projects).

Key takeaways

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

Reference excerpt

Germplasm Resources Information Network or GRIN is an online USDA National Genetic Resources Program software project to comprehensively manage the computer database for the holdings of all plant germplasm collected by the National Plant Germplasm System. GRIN has extended its role to manage information on the germplasm reposits of insect (invertebrate), microbial, and animal species (see sub-projects).

Description The site is a resource for identifying taxonomic information (scientific names) as well as common names on more than 500,000 accessions (distinct varieties, cultivars etc.) of plants covering 10,000 species; both economically important ones and wild species. It profiles plants that are invasive or noxious weeds, threatened or endangered, giving out data on worldwide distribution of its habitat; as well as passport information. GRIN also incorporates an Economic Plants Database. The network is maintained by GRIN's Database Management Unit (GRIN/DBMU). GRIN is under the oversight of National Germplasm Resources Laboratory (NGRL) in Beltsville, Maryland, which in 1990 replaced its forerunner, the Germplasm Services Laboratory (GSL), that had formerly run GRIN. Since November, 2015 GRIN has been running on GRIN-Global software produced by a collaborative project between the USDA and the Global Crop Diversity Trust.

Sub-projects A stated mission of GRIN is to support the following projects:

National Plant Germplasm System (NPGS) National Animal Germplasm Program (NAGP) National Microbial Germplasm Program (NMGP) National Invertebrate Germplasm Program (NIGP)

Worked examples

Example 1 — a first encounter with Germplasm Resources Information Network

Start with the simplest possible case. Write down what Germplasm Resources Information Network claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, 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 Germplasm Resources Information Network 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 Germplasm Resources Information Network 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 Germplasm Resources Information Network

In research: Germplasm Resources Information Network appears in computer science 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 Germplasm Resources Information Network 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: Germplasm Resources Information Network is common in secondary-school and first-year university syllabi. It links to neighbouring topics Biodiversity databases, Genetics organizations, Online taxonomy databases, so understanding it makes those chapters shorter.
In everyday life: Look for Germplasm Resources Information Network 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.
