Genome-wide excision repair in Arabidopsis is coupled to transcription and reflects circadian gene expression patterns (Nature Comms)

Exposure to ultraviolet radiation and numerous other factors can cause mispairing of the nucleotides in the DNA, compromising genome integrity. Luckily, plants employ excision repair systems to recognize and repair such DNA damage. Oztas et al. examined the dynamics of such a repair system by using excision…

How Plants Clear Toxic Proteins

Gil et al. explore ZTL-mediated protein quality control https://doi.org/10.1105/tpc.17.00612 By Kyung-Eun Gil Background: As sessile organisms, plants have evolved various mechanisms to adapt to environmental changes. Under stressful conditions such as high temperatures, proteins are misfolded…

CIRCADIAN CLOCK ASSOICATED 1 (CCA1) and the circadian control of stomatal aperture

How do plants ‘decide’ how to respond to so many conflicting stimuli? What has the final say in stomatal aperture control? Hassidium et al. investigate the role of the oscillator gene CIRCADIAN CLOCK ASSOICATED 1 (CCA1) during stomatal opening and determined if CCA1 is responsive to other stimuli.…

Stop the Clock: Optimized Carbon Fixation and Circadian Rhythm in a CAM Plant

The energetically costly tendency of the carbon fixing enzyme RuBisCO to, every now and then, fix oxygen instead of carbon dioxide has led to the evolution of various carbon concentrating mechanisms in plants and algae. One such mechanism, Crassulacean acid metabolism (CAM), involves primary CO2 fixation…
