Researchers from Oregon State University have revealed the earliest
evidence of sexual reproduction in flower plants in a new report published
in the Journal of the Botanical Institute of Texas.
http://brit.org/webfm_send/455
The evidence was found in a 100-million-year old piece of amber containing
a bunch of 18 previously-undescribed flowers from the Cretaceous Period.
Dubbed Micropetasos burmensis, the flowers were frozen in the process of
making new seeds.
.
Like many other plants and insects preserved in amber, the flowers are
essentially frozen in time with nearly every detail appearing as it had
millions of year ago. The preservation process began with flowing tree sap
covering the flowers. Eventually, the sap hardened into a fossilized,
semi-precious gem.
.
The flower cluster came from a time when many of the flowering plants on
Earth were still fairly small. During the Cretaceous, flowering plants
started to emerge, providing increased biodiversity and food. Until the
Cretaceous, plant life on Earth was composed entirely of conifers, ferns,
mosses, and cycads.
.
The remarkable amount of preservation allowed the OSU scientists to
capture microscopic images of pollen tubes emerging from two grains of
pollen and entering the flower's stigma, direct evidence of sexual
reproduction. The pollen tubes allow for the fertilization of the egg
within the stigma and the eventual formation of a seed.
.
"In Cretaceous flowers we've never before seen a fossil that shows the
pollen tube actually entering the stigma," said study author George
Poinar, Jr., a professor of integrative biology at OSU. "This is the
beauty of amber fossils. They are preserved so rapidly after entering the
resin that structures such as pollen grains and tubes can be detected with
a microscope."
