The toc1 mutation causes shortened circadian rhythms in light-grown Arabidopsis plants.
Here, we report the same toc1 effect in the absence of light input to the clock. We also show …

The temporal control of CONSTANS (CO) expression and activity is a key mechanism in
photoperiodic flowering in Arabidopsis. FLAVIN-BINDING, KELCH REPEAT, F-BOX 1 (FKF1) …

The circadian clock is required for adaptive responses to daily and seasonal changes in
environmental conditions 1 , 2 , 3 . Light and the circadian clock interact to consolidate the …

A crucial requirement in the rational design of a prophylactic vaccine against the hu-uman
immunodeficiency virus (HIV) is to establish whether or not protective immunity can occur …

We have conducted genetic screens for period length mutants in Arabidopsis using a transgenic
bioluminescence phenotype. This screen identified mutations at a locus, ZEITLUPE (ZTL…

Members of the order Coleoptera are sometimes referred to as ‘living jewels’, in allusion to
the strikingly diverse array of iridescence mechanisms and optical effects that have arisen in …

… This paper was presented by Thomas H. Schultz in the Symposium on Methods for Isolation
of Trace Volatile Constituents, Agricultural and Food Chemistry Division, 172nd National …

In higher plants, the circadian clock orchestrates fundamental processes such as light
signaling and the transition to flowering. We isolated mutants of the circadian clock from an …

We present experimental and theoretical evidence for an excited-state deactivation
mechanism specific to hydrogen-bonded aromatic dimers, which may account, in part, for the …

We present femtosecond time-resolved photoelectron spectra (TRPES) of the DNA and RNA
bases adenine, cytosine, thymine, and uracil in a molecular beam. We discuss in detail the …
