Traversing Swanton Road, 3rd Ed., James A. West Jan 2011

Traversing Swanton Road, 3rd Ed., James A. West

Academic, Government & Associated Organizational Research Resources

Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …

Biological Sciences Faculty and Staff Research

• Premise of the study : The clusioid clade includes five families (i.e., Bonnetiaceae, Calophyllaceae, Clusiaceae s.s., Hypericaceae, and Podostemaceae) represented by 94 genera and ~1900 species. Species in this clade form a conspicuous element of tropical forests worldwide and are important in horticulture, timber production, and pharmacology. We conducted a taxon-rich multigene phylogenetic analysis of the clusioids to clarify phylogenetic relationships in this clade. • Methods : We analyzed plastid ( matK , ndhF , and rbcL ) and mitochondrial ( matR ) nucleotide sequence data using parsimony, maximum likelihood, and Bayesian inference. Our combined data set included 194 …

Aceraceae - Acer Griseum, Janice Coons, Nancy Coutant, Wesley Whiteside

Plants by Family

Acer griseum was first brought to North America in 1907 by Ernest Henry Wilson in the form of two seedlings that were collected from Hubei Province in China. These two original plants remain at the Arnold Arboretum in Boston, Massachusetts, and were the source of the first North American horticultural distribution of the plant in 1927 (Del Tredici 2007). It is a handsome plant with very showy bark and is becoming more popular and easier to obtain than it has been in the past.

Plants by Genus Species

Cedar of Lebanon had an extensive ancient range through Lebanon, Syria, and Southern Turkey. It now is greatly reduced and fragmented through economic exploitation for 5000 years, agricultural clearing, and war. Populations are found in the Taurus Mountains and Black Sea region of Turkey, the eastern side of Jabal an-Nusayriya in Syria, and the western mountain range in Lebanon (Khuri 2000).

[Accepted Article Manuscript Version (Postprint)] Pex5 Mutants That Differentially Disrupt Pts1 And Pts2 Peroxisomal Matrix Protein Import In Arabidopsis, Bibi Khan, Bethany Zolman Dec 2010

[Accepted Article Manuscript Version (Postprint)] Pex5 Mutants That Differentially Disrupt Pts1 And Pts2 Peroxisomal Matrix Protein Import In Arabidopsis, Bibi Khan, Bethany Zolman

Biology Department Faculty Works

PEX5 and PEX7 are receptors required for the import of peroxisome-bound proteins containing one of two peroxisomal targeting signals (PTS1 or PTS2). To better understand the role of PEX5 in plant peroxisomal import, we characterized the Arabidopsis (Arabidopsis thaliana) pex5-10 mutant, which has a T-DNA insertion in exon 5 of the PEX5 gene. Sequencing results revealed that exon 5, along with the T-DNA, is removed in this mutant, resulting in a truncated pex5 protein. The pex5-10 mutant has germination defects and is completely dependent on exogenous Suc for early seedling establishment, based on poor utilization of seed-storage fatty acids. This …
