In this paper, a comprehensive study of the fate of an antibiotic, lincomycin, in the aquatic environment is presented. High-resolution mass spectrometry was employed to assess the evolution of the process over time. Formation of intermediate compounds was followed by
Plant physiology, 159(1), 366-390 (2012-03-03)
We previously provided evidence that plastid signaling regulates the downstream components of a light signaling network and that this signal integration coordinates chloroplast biogenesis with both the light environment and development by regulating gene expression. We tested these ideas by
Chloroplast movement provides photoprotection to plants by redistributing PSII damage within leaves.
Photosynthesis research, 112(3), 153-161 (2012-06-15)
Plants use light to fix carbon through the process of photosynthesis but light also causes photoinhibition, by damaging photosystem II (PSII). Plants can usually adjust their rate of PSII repair to equal the rate of damage, but under stress conditions

A fast liquid chromatography-tandem mass spectrometry (LC-MS-MS) method is developed to determine lincomycin (LM) in honey, muscle, milk, and egg. Samples are cleaned-up at pH 4.7 using Strata-X-C mixed-mode polymeric strong cation exchange solid-phase extraction (SPE) cartridges, which could selectively
Photosynthesis research, 113(1-3), 165-180 (2012-07-17)
When visible light is excess, the photosynthetic machinery is photoinhibited. The extent of net photoinhibition of photosystem II (PSII) is determined by a balance between the rate of photodamage to D1 and some other PSII proteins and the rate of

Lincomycin A is a potent antimicrobial agent noted for its unusual C1 methylmercapto-substituted 8-carbon sugar. Despite its long clinical history for the treatment of Gram-positive infections, the biosynthesis of the C(8)-sugar, methylthiolincosamide (MTL), is poorly understood. Here, we report our
