siea. Low temperature is the key factor that limits
the growth, colour and appreciatability in winter in the northern of China. Introducing foreign gene
into kale through genetic engineering may create novel variety with cold tolerance. In this study,
BADH(encoding betaine aldehyde dehydrogenase) and TCH(encoding transcription regulation
factors) were used to be transformed into kale with Agrobacterium-mediated transformation.
