+# Plant foundation DNA large language models
+
+The plant DNA large language models (LLMs) contain a series of foundation models based on different model architectures, which are pre-trained on various plant reference genomes.  
+All the models have a comparable model size between 90 MB and 150 MB, BPE tokenizer is used for tokenization and 8000 tokens are included in the vocabulary.  
+
+
+**Developed by:** zhangtaolab
+
+### Model Sources
+
+- **Repository:** [Plant DNA LLMs](https://github.com/zhangtaolab/plant_DNA_LLMs)
+- **Manuscript:** [Versatile applications of foundation DNA language models in plant genomes]() 
+
+### Architecture
+
+The model is trained based on the Google BERT base model with modified tokenizer specific for DNA sequence.
+
+This model is fine-tuned for predicting H3K27ac histone modification.
+
+
+### How to use
+
+Install the runtime library first:
+```bash
+pip install transformers
+```
+
+Here is a simple code for inference:
+```python
+from transformers import AutoModelForSequenceClassification, AutoTokenizer, pipeline
+
+model_name = 'plant-dnabert-H3K27ac'
+# load model and tokenizer
+model = AutoModelForSequenceClassification.from_pretrained(f'zhangtaolab/{model_name}', trust_remote_code=True)
+tokenizer = AutoTokenizer.from_pretrained(f'zhangtaolab/{model_name}', trust_remote_code=True)
+
+# inference
+sequences = ['GCTTTGGTTTATACCTTACACAACATAAATCACATAGTTAATCCCTAATCGTCTTTGATTCTCAATGTTTTGTTCATTTTTACCATGAACATCATCTGATTGATAAGTGCATAGAGAATTAACGGCTTACACTTTACACTTGCATAGATGATTCCTAAGTATGTCCT',
+             'TAGCCCCCTCCTCTCTTTATATAGTGCAATCTAATATATGAAAGGTTCGGTGATGGGGCCAATAAGTGTATTTAGGCTAGGCCTTCATGGGCCAAGCCCAAAAGTTTCTCAACACTCCCCCTTGAGCACTCACCGCGTAATGTCCATGCCTCGTCAAAACTCCATAAAAACCCAGTG']
+pipe = pipeline('text-classification', model=model, tokenizer=tokenizer,
+                trust_remote_code=True, top_k=None)
+results = pipe(sequences)
+print(results)
+
+```
+
+
+### Training data
+We use BertForSequenceClassification to fine-tune the model.  
+Detailed training procedure can be found in our manuscript.
+
+
+#### Hardware
+Model was trained on a NVIDIA GTX1080Ti GPU (11 GB).
