+# 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 large language models in plant genomes]() 
+
+### Architecture
+
+The model is trained based on the State-Space Mamba-130m model with modified tokenizer specific for DNA sequence.
+
+This model is fine-tuned for predicting promoter strength in maize protoplasts system.
+
+
+### How to use
+
+Install the runtime library first:
+```bash
+pip install transformers
+pip install causal-conv1d<=1.2.0
+pip install mamba-ssm<2.0.0
+```
+
+Since `transformers` library (version < 4.43.0) does not provide a MambaForSequenceClassification function, we wrote a script to train Mamba model for sequence classification.  
+An inference code can be found in our [GitHub](https://github.com/zhangtaolab/plant_DNA_LLMs).  
+Note that Plant DNAMamba model requires NVIDIA GPU to run.
+
+
+### Training data
+We use a custom MambaForSequenceClassification script to fine-tune the model.  
+Detailed training procedure can be found in our manuscript.
+
+
+#### Hardware
+Model was trained on a NVIDIA GTX4090 GPU (24 GB).
