Cells, 2021 Phototropins are plasma membrane-associated photoreceptors of blue light and UV-A/B radiation. The Arabidopsis thaliana genome encodes two phototropins, PHOT1 and PHOT2, that mediate phototropism, chloroplast positioning, and stomatal opening.

Limnology and Oceanography, Volume 67, Issue 12, Page 2718-2733, December 2022., 2022 Abstract Continental freshwater systems are particularly vulnerable to environmental variation. Climate change‐induced desertification and the anthropogenic exploitation of hydric resources result in the progressive evaporation and salinization of inland water bodies in many areas of the globe.

Production and Scavenging of Reactive Oxygen Species in Chloroplasts and Their Functions1
Plant Physiology, 2006 The reaction centers of PSI and PSII in chloroplast thylakoids are the major generation site of reactive oxygen species (ROS). Photoreduction of oxygen to hydrogen peroxide (H2O2) in PSI was discovered over 50 years ago by [Mehler (1951)][1 ...

Chloroplast microsatellites: measures of genetic diversity and the effect of homoplasy [PDF]
Molecular Ecology 14, 5 (2005) 1333-41, 2009 Chloroplast microsatellites have been widely used in population genetic studies of conifers in recent years. However, their haplotype configurations suggest that they could have high levels of homoplasy, thus limiting the power of these molecular markers.

The use of an automated organism tracking microscope in mesocosm experiments
Limnology and Oceanography: Methods, Volume 20, Issue 12, Page 768-780, December 2022., 2022 Abstract A method for automatically counting and measuring sizes and motility behavior of zooplankton and phytoplankton in water samples is presented. Two video cameras are focused on separate optical chambers of different sizes. The chambers are filled and emptied repeatedly by synchronized pumps.
