Scientists in California and Virginia will try to decode
genetic makeup of two plant-destroying microbes, including 【M1】______
one blaming for killing tens of thousands of oak trees along the 【M2】______
West Coast.
Backed by $4 million in federal grants, the scientists hope
to sequence the genomes of the two species of Phytophthora.
The most notorious of the pair is P. ramorum, that causes sudden【M3】______
oak death syndrome.
With the genomes in hand, scientists expect to develop
the mean to track, detect and, eventually, treat both diseases.【M4】______
P. ramorum has killed tens of thousands of black oak,
coast live oak and tan oak trees in northern California and
southern Oregon as it first appeared in 1995. This year, 【M5】______
scientists invented coast redwoods and Douglas fir also 【M6】______
are susceptible, as is at least 14 other plant species. 【M7】______
At the same time, scientists at the Walnut Creek laboratory
and at the Virginia Bioinformatics Institute in Blacksburg will
sequence the genome of P. sojae, a related microbe
responsible soy rot, which is estimated to cause $1 billion in 【M8】______
damages to soy Bean crops worldwide. Both sequences will be
free available on the Internet once completed. 【M9】______
The two species of funguslike organisms are closely
related to algae. Among their relatives is P. infestans, the microbe
responsible for the failure of potato crops in Ireland in the
19th century and the resulting famine. The name
Phytophthora means "plant devourer" in Greece. 【M10】______ [br] 【M3】
