FIGURE 4.

Photomicrographs showing the distribution of several tri-nucleotide SSRs (AGG, AGC, and ATC) on metaphase chromosomes of Wu ta cai, Fen nie cai, and Tai cai. (a,b) in Wu ta cai; (c–e) in Fen nie cai; (f,g) in Tai cai; (h–k) variation in the number of signal sites in Wu ta cai; (l–o) variation in the number of signal sites in Tai cai; lines indicate the number of fluorescent signals in Wu ta cai and Tai cai; arrows indicate different intensity fluorescent signals. Chromosomes were counterstained with DAPI.
