Fig. 5: Independent expansions of LFS and ALL gene families between bunching onion and garlic.

a, b The micro-collinearity relationship of LFS (a) and ALL (b) in A. fistulosum and A. sativum. The red lines indicate genes were expanded in A. fistulosum, the blue lines indicate genes were expanded in A. sativum, and the gray lines indicate other genes which show collinearity relationships. c, d The gene duplication relationships of LFS (c) and ALL (d) in A. fistulosum. The blue line indicates dispersed duplication relationship, the green line indicates tandem duplication relationship, and the yellow line indicates proximal duplication relationship. The gene details are listed in Supplementary Data 1–3.
