Vegetatively propagated peppermint (Mentha piperita L., cv. Black Mitcham) was used to determine the effects of night temperatures (8°C vs 25°C) on the plant growth in terms of fresh weight and leaf area, and on metabolite contents. The plants were sampled after 14 days, 21 days and 28 days in...
This paper describes a learning control system which is capable
of controlling a linear plant subjected to periodic inputs, providing
that an upper limit for the order of the plant is known. Otherwise the
characteristics of the plant and the inputs are unknown. Only one
system variable is measured. The...
PCR-based codon-specific random mutagenesis and site-specific mutagenesis were performed to construct a library of 18 amino acid changes at Arg276 in the conserved leucine-loop of the core catalytic domain of human uracil-DNA glycosylase (UNG). Each Arg276 mutant was then overproduced in E. coli cells and purified to apparent homogeneity by...
Background: Little is known about the potential of Brachypodium distachyon as a model for low temperature stress
responses in Pooideae. The ice recrystallization inhibition protein (IRIP) genes, fructosyltransferase (FST) genes, and
many C-repeat binding factor (CBF) genes are Pooideae specific and important in low temperature responses. Here
we used comparative...
The West Antarctic Ice Sheet Divide (WAIS Divide, WD) ice core is a newly drilled, high-accumulation
deep ice core that provides Antarctic climate records of
the past ~68 ka at unprecedented temporal resolution. The
upper 2850 m (back to 31.2 ka BP) have been dated using
annual-layer counting. Here we...

Internal waves of depression were observed propagating
along‐shelf and into northern Monterey Bay, California
(CA) on the inner shelf. These waves had amplitudes
approximately equal to the thermocline depth (∼4 m), and
were unstable to shear and mix the thermocline. Isopycnal
gradient spectra showed that the wave packets lead to...
Neurospora crassa has been for decades a principal model for filamentous
fungal genetics and physiology as well as for understanding
the mechanism of circadian clocks. Eukaryotic fungal and animal
clocks comprise transcription-translation-based feedback loops that
control rhythmic transcription of a substantial fraction of these transcriptomes,
yielding the changes in protein...
