## Map between Manufacturer Identifiers and Gene Symbols

### Description

ath1121501SYMBOL is an R environment that provides mappings between manufacturer identifiers and gene abbreviations.

### Details

Each manufacturer identifier is mapped to an abbreviation for the corresponding gene. An `NA` is reported if there is no known abbreviation for a given gene.

Symbols typically consist of 3 letters that define either a single gene (ABC) or multiple genes (ABC1, ABC2, ABC3). Gene symbols can be used as key words to query public databases such as Entrez Gene.

Mappings were based on data provided by:
