Regulation of monocot and dicot plant development with constitutively active alleles of phytochrome B

open access: yesPlant Direct, 2020
The constitutively active missense allele of Arabidopsis phytochrome B, AtPHYBY276H or AtYHB, encodes a polypeptide that adopts a light‐insensitive, physiologically active conformation capable of sustaining photomorphogenesis in darkness.

Phytochrome B and REVEILLE1/2-mediated signalling controls seed dormancy and germination in Arabidopsis

open access: yesNature Communications, 2016
Seed dormancy prevents germination under adverse environmental conditions. Here the authors show that the RVE1 and RVE2 transcription factors suppress biosynthesis of the germination-promoting hormone GA and act downstream of phytochrome signalling to ...

Effects of Low-Level Artificial Light at Night on Kentucky Bluegrass and an Introduced Herbivore

open access: yesFrontiers in Ecology and Evolution, 2021
Increasing evidence suggests that artificial light at night (ALAN) can negatively impact organisms. However, most studies examine the impacts of ALAN on a single species or under high levels of artificial light that are infrequent or unrealistic in urban

Effects of Glyphosate-Based Herbicide on Primary Production and Physiological Fitness of the Macroalgae Ulva lactuca

open access: yesToxics, 2022
The use of glyphosate-based herbicides (GBHs) worldwide has increased exponentially over the last two decades increasing the environmental risk to marine and coastal habitats. The present study investigated the effects of GBHs at environmentally relevant

Photochemistry and Photobiology of the Spore Photoproduct: A 50-Year Journey

open access: yes, 2015
Fifty years ago, a new thymine dimer was discovered as the dominant DNA photolesion in UV-irradiated bacterial spores [Donnellan, J. E. & Setlow R. B. (1965) Science, 149, 308-310], which was later named the spore photoproduct (SP).

Unique Cl– pump rhodopsin with close similarity to H+ pump rhodopsin

open access: yesBiophysics and Physicobiology, 2022
Microbial rhodopsin is a ubiquitous membrane protein in unicellular microorganisms. Similar to animal rhodopsin, this protein consists of seven transmembrane helices and the chromophore retinal.
