| Comments |
"The new data available have extended the range of
genome sizes encountered in land plants at both ends of
the scale so C-values now vary nearly 2,400-fold. Both
record holders are angiosperms with the smallest reported
in the eudicot genus Genlisea (G. aurea 1C=0.065 pg,
Fig. 19.2a) (Greilhuber et al. 2006 the report of 0.065 pg
for G. margaretae actually belongs to G. aurea
J. Greilhuber, pers. comm.) while the largest to date is in
the monocot Paris japonica which is an octoploid with 2n=8x=40 and a staggering 1C=152.23 pg (primary source)(Fig. 19.2b)." "...a 1C-value refers to the
amount of DNA in an unreplicated, gametic nucleus with a
chromosome number n." Primary source abstract:"[Researchers] report the largest eukaryotic genome to date in the monocot Paris japonica (Melanthiaceae, 1C = 152.23 pg),
measured using flow cytometry. This value is 15% larger than any previous estimate and extends the range of
genome sizes to c. 2400-fold across angiosperms and c. 66 000-fold across eukaryotes." |
