Micropropagating American chestnut plantlets in the Plant Tissue Culture Lab at @SUNY ESF 🔪🌱 More information: These clonally propgated chestnuts are not meant for restoration or field plantings. We use tissue culture trees for research purposes only such as studying OxO gene expression or conducting controlled fungal inoculations. We also put tissue culture generated trees into high light growth chambers to produce transgneic pollen to be used in controlled pollinations! #americanchestnut #bi
