105 Propagation of Taxodium mucronatum (Montezuma Cypress)

An rbcL sequence from a Miocene Taxodium (bald cypress).

During the past decade, ancient DNAs from both animals and plants have been successfully extracted and analyzed. Recently, the age of DNA that can be recovered and sequenced was increased manyfold by the amplification and sequencing of a DNA fragment from a Magnolia fossil obtained from the Miocene Clarkia deposit (17-20 million yr old). However, the validity of this report has been questioned ...

Endophytic taxol-producing fungi from bald cypress, Taxodium distichum.

Pestalotiopsis microspora occurs as a range of strains in bald cypress, Taxodium distichum. The organisms live as endophytes in the bark, phloem and xylem, and isolates show differences in cultural and microscopic characteristics on common laboratory media. Many of these fungi make taxol as determined by the reactivity of partially purified culture extracts with specific monoclonal antibodies a...

Seed germination enhancement for bald cypress [Taxodium distichum (L.) Rich.]

Bald cypress has been retreating in the estuary ecosystem of the Loxahatchee River Watershed in southeastern Florida because of the negative impacts of anthropogenic activities. Seed germination of bald cypress is an important means to increase the arbor population in the vegetation community and accelerate restoration of the wetland ecosystem. The objective of this research was to find an effe...

Nitrogen Fixation (Acetylene Reduction) Associated with Decaying Leaves of Pond Cypress (Taxodium distichum var. nutans) in a Natural and a Sewage-Enriched Cypress Dome.

Surface litter from a natural and a sewage-enriched cypress dome in north-central Florida showed a pronounced seasonal pattern of nitrogenase (acetylene reduction) activity associated with seasonal leaf fall from deciduous trees in the domes. Samples of peat from cores indicated negligible nitrogenase activity below the surface layer. Integrating the monthly rates of nitrogen fixation (based on...
