(Utricularia), a carnivorous plant with a minimal genome," BMC Plant Biology, vol.
Food composition of aquatic bladderworts
(Utricularia, Lentibulariaceae) in various habitats.
That is, at three distinct times in the course of its evolution, the bladderwort
's genome doubled in size, with offspring receiving two full copies of the species' entire genome.
The scientists said that it seems that the plant has been busy deleting noncoding "junk" DNA from its genetic material over many generations, which may explain differences between bladderworts
and junk-heavy species like corn and tobacco - and humans.
Scientists, including the famous naturalist Charles Darwin, have marveled at the bladderwort
's traps for more than 100 years.
Unexpectedly, at the lowest nitrogen level, trapping of Euglena depressed plant growth, apparently because it competed with the bladderwort
for nitrogen under these conditions -- the prey here acting as a parasite.
Obligatory tedium began with unregulated steward calcification of the most horrid sort; pleasantries aside, shimmying along amnesia's inner membrane wasn't so much like Yahweh's clattering as one might not have thought had one not been cleansed by the temptress of bladderwort
By the photos on a Northwest Ontario website, I positively identified our nemeses: milfoil, horsetail, bladderwort
, bulrush, arrowhead, and duckweed.
Rootless and adrift in its wetland habitat, the humped bladderwort
(Utricularia gibba) preys on water fleas and other small invertebrates.
On its southern shore is a fen, where visitors can find cranberries and insect-eating plants such as sundew, pitcher plant and bladderwort
