Putative light-sensing proteins are ubiquitously encoded in the genomes of chemotrophic,
non-photosynthetic bacteria. Surprisingly, these are not limited to UV-receptors: the …

Selman Waksman's seminal discovery that streptomycin, a natural product produced by
Streptomyces griseus, 1 could be used to treat tuberculosis set the stage for decades of …

Fluorescent reporter proteins such as green fluorescent protein are valuable noninvasive
molecular tools for in vivo real-time imaging of living specimens. However, their use is …

Purpose: Carotenoids are of great interest in many scientific disciplines because of their
wide distribution, diverse functions and interesting properties. The present report describes …

Previous work on possible surface reflectance biosignatures for Earth-like planets has
typically focused on analogues to spectral features produced by photosynthetic organisms …

Sequencing of Streptomyces genomes has revealed they harbor a high number of
biosynthesis gene cluster (BGC), which uncovered their enormous potentiality to encode …

Control of carotenoids production from the yeast Rhodotorula mucilaginosa AY-01, based
on the results of 28S rDNA sequence (D1/D2 region) analysis and homology search, was …

Background In a number of gram-positive bacteria, including Listeria, the general stress
response is regulated by the alternative sigma factor B (SigB). Common stressors which …

Members of the marine actinomycete genus S alinispora constitutively produce a
characteristic orange pigment during vegetative growth. Contrary to the understanding of …

A light‐inducible promoter, PB, drives expression of the carB operon in Myxococcus
xanthus. Repressed by CarA in the dark, PB is activated when CarS, produced in the light …
