Sv. Pillai et al., YEAST AND BACTERIAL ARTIFICIAL CHROMOSOME (YAC AND BAC) CLONES OF THEMODEL LEGUME LOTUS-JAPONICUS, Symbiosis, 21(2), 1996, pp. 149-164
Lotus japonicus is a model legume with a small diploid genome (n=6), s
hort life cycle and high transformation ability. As a step towards pos
itional cloning of developmental genes in L. japonicus we cloned piece
s of high molecular weight (HMW) DNA into yeast and bacterial artifici
al chromosomes vectors (YACs and BACs) and transformed them into their
respective hosts. Standardized cloning and transformation conditions
as well as verification of inserts by pulsed field gradient electropho
resis (PFGE) and Southern hybridization are described.
