# Promoter Sequences for Various plant species
The data in this dataset has the promoter sequences for **241 different plant species** and has been used for the pretraining step of [`Florabert`](https://huggingface.co/Gurveer05/FloraBERT). It has been created by processing the raw fasta files and the gff3 / gff files from [`Ensembl`](https://plants.ensembl.org/) and [`Refseq`](https://www.ncbi.nlm.nih.gov/refseq/).
*samtools* and *bedtools* have been used to extract the promoter sequences from these that are 1kb upstream of the sequence.
The data has been split into train and test data (90-10 split). In all, there are ~ 10 million sequences across the split files. The steps followed to obtain this data are available in this [`Github Repository`](https://github.com/gurveervirk/florabert). |
